Abstract Background: Tip-plasty is the most technically demanding among all the stages of rhinoplasty. The complex3-dimensional structure of the nasal tip and the essential relationship between the nasal tip, and the remaining upper two thirds of the nose have precipitated the development of numerous techniques for tip-plasty. Suture technique is used to alter the shape of the nose while preserving or reconstructing tip-support structures.

Aim of the Study: To evaluate the effectiveness of using 4-suture technique to control nasal tip dynamics including (tip shape, tip symmetry and tip definition point) .The four sutures include a medial crural suture, bilateral transdomal suture, and an interdomal suture.

Patients and methods: An experimental prospective, observational (follow up) study was conducted on 54 patients ( 14 males and 40 females) aging between 18-54 years, who underwent open rhinoplasty with 4- suture tip plasty in (ENT ,Head and Neck Surgery-Sulaimani Teaching Center ) and (Azmar Private Hospital) from 1st January 2016 - 1st September 2016. , by means of the questionnaire and comparing photography of preoperative, and 3, 6 months after the surgery. Collected data had been analyzed statistically, using SPSS version (21).

Results : Fifty-four patients underwent primary open rhinoplasty and had an overall variable average score of 2.22 and 2.51 for follow-up period of 3and 6 months respectively on a -3 to +3 scale.

Conclusions: Four sutures is powerful technique for controlling tip symmetry, tip shape, and better alignment of tip definition point, and improving overall aesthetics and natural appearing results of nose. So the 4-suture technique is a useful technique to be added into the armamentarium of the rhinoplastic surgery.

Key words: Rhinoplasty, Four Suture Technique, Tip Plasty.

1.1 Introduction The term Rhinoplasty means "nose molding", it refers to a procedure in Plastic Surgery in which the structure of the nose is changed, the change can be made by adding or removing bone or cartilage, grafting tissue from another part of the body, or implanting synthetic material to alter the shape of the nose. Cosmetic Rhinoplasty is nose surgery that is done to improve the appearance of the nose. A person may choose this type of surgery to feel better about his or her appearance. Functional Rhinoplasty can repair nose defects that are caused by an injury. It is also used to correct birth defects or improve some breathing problems. (1) Among all the stages of rhinoplasty,tip-plasty is the most technically demanding. Multiple characteristics of the nasal tip, including rotation, projection, definition, and symmetry must be addressed to achieve an aesthetically pleasing result. (2,3)The complex3-dimensional (3D) structure of the nasal tip, and the essential relationship between the nasal tip and the remaining upper two thirds of the nose have precipitated the development of numerous techniques for tip-plasty. The goal of these approaches which are (the 4 sutures include a medial crural suture, bilateral intradomal sutures, and an interdomal suture), is to alter the shape of the nose while preserving or reconstructing tip-support structures.

1.2 Anatomy: 1.2.1Skin: The skin is thinner and more mobile in the upper two thirds of the nose. In the lower third and especially at the nasal lobule, the skin becomes thicker, more sebaceous, and more adherent to the underlying structures (5) 1.2.2 Soft Tissue Layers Beneath the Skin: There are four distinct layers that occupy the area between the skin and the underlying osseocartilaginous frame: the Superficial Musculoaponeurotic System (SMAS) as originally described by Tessier, Fibromuscular layer, Deep fatty layer, and Periosteum/Perichondrium. Immediately under the skin, there is a superficial fatty panniculus, which is largely occupied by adipose tissue containing some vertical fibers and septi running from the skin to the underlying SMAS.Under the SMAS, there is a thin fibrofatty layer that divides to encase the superficial and deep muscles of the nose.(3,4) Wherever there is no muscle, these two layers join, creating a single layer. The third layer of the nose is the deep fatty layer that separates the fibromuscular layer from the underlying nasal frame. The fourth soft tissue layer is the periosteum over the nasal bones and the perichondrium over the cartilaginous frame.(6) 1.2.3 Musculature: The muscles of the nose are primarily elevators, which shorten the nose and dilate the nostrils. One of these is the M.procerus, which can be regarded as a continuation of the frontal muscle and is inserted on the aponeurotic layer of the nasal dorsum (Fig. 1). This layer can be found on the lower aspect of the nasal bones and the upper part of the upper lateral cartilages. The M. Dilator (pars 2

alarismusculinasalis) opens the nostrils and originates from the nasomaxillary suture and fibrofatty tissue which support the lower laterals with the piriform aperture. Its insertion is at the skin of the nasolabial groove.The M. levatorlabii superior dilates the nares and originates in the frontal process of the maxillary bone. It is attached to the perichondrial layer of the lower lateral cartilage. The M. depressor septi lowers the nasal tip and opens the nostrils in deep inspiration. It forms part of the orbicularismuscle of the upper lip and inserts in the columella. The only muscle to effect compression of the nose, lengthen the nose and contract the nostrils is the M. nasalis (parstransversamusculinasalis). Therefore, itantagonizes the M. procerus. It originates immediately lateral to the piriform aperture and inserts in the aponeurotic layer on the nasal dorsum.(7) All this muscular tissue should be protected during rhinoplasty, since its injury can cause a rigid appearance and immovabilityof the nose. A tension nose can be regarded as an exception to this rule.Surgical division of the M. depressor septi to release the pull at the nasal tip can then be advocated.(7)

1.2.4 Bony pyramid The nasal bones unite with each other in the midline, with the frontal bone superiorly at the nasofrontal suture and laterally with the frontal process of the maxilla at the nasolacrimal suture ,they are supported by the nasal spine of the frontal bone and by the perpendicular plate of the ethmoid, both of which groove the bones. The nasal bone is wedge-shaped, usually convex and smooth on its outer surface and concave and roughened internally, (Fig.2). The bones are grooved by adjacent neurovascular bundles. There is considerable ethnic and individual variation in the shape and size of the nasal bones .The inferior border of the pyramid up to the anterior nasal spine is called the piriform aperture and it is about be up to 15 mm in length.(8)

1.2.5 Cartilaginous Pyramid The nasal cartilages are composed of hyaline cartilage which may be ossified. They prevent collapse of the vestibule on inspiration. The upper cartilages are triangular flat expansions lying inferior to the nasal bones and are overlapped by them, by the adjacent frontal processes of the maxillae and by the lower lateral cartilages. The groove between the upper and lower lateral cartilages is known as the Limen Nasi, which is the site of intercartilaginous incisions. The medial aspects of the upper lateral cartilages are continuous with the nasal septal cartilage which is bifid in this area. The lower lateral or alar cartilages form the lower third of the nose. They are each composed of medial and lateral crus which meet at the dome of the tip, though the highest point can be on the lateral crus. The medial crura are loosely attached to each other in the midline and contribute to the Columella, anterior to the quadrilateral cartilage. The lower margin of the lateral crus does not follow the 4

margin of the nostril but ascends away from the margin laterally. Between one and four minor sesamoid cartilages are found between the upper and lower lateral cartilages. The part of the septum running between the tip of the nose and philtrum is called the columella. It bounds the anterior nares medially and is thicker posteriorly because of the contribution made by the medial crura of the lower lateral cartilages.(8) Three different forms of overlap between upper and lower lateral cartilage can be found. A true roof tile overlap is most frequently seen in which the cephalic margin of the lower lateral covers the free caudal margin of the upper lateral. In the second form of overlap the cephalic margin of the lower lateral covers a reverse curled free caudal margin of the upper lateral cartilage. This variation can be identified when the vestibulum is inspected in the valve area. Sometimes a true overlap between lower and upper lateral cartilage is missing mostly due to the aging process. An intercartilaginous incision, to undermine the nasal dorsum, will loosen this prominent support mechanism which could result in tip ptosis. The tip is the most forward projecting part of the lobule. The part immediately above the tip is called the supratip and the part below the intratip. The lower lateral cartilages encompass the nostrils, leaving a small triangular area between the medial and lateral crus (soft triangle of Converse). The medial component or medial crus forms the columella and the lateral component or lateral crus provide the cartilaginous framework of the ala. The medial footplate attachment to the caudal border of the septal cartilage forms the second major tip support mechanism. The junction of the columella and the upper lip forms the nasolabial angle. Changes of this angle can give the illusion of rotation of the tip. A blunt angle results in an upward rotation, e.g., a prominent anterior nasal spine or overdevelopment of the septal cartilage. A Sharp angle results in a downward rotation, e.g., underdevelopment of the septal cartilage or excessive resection of cartilage (‘retracted columella’). The lateral 5

crura diverge in the supratip area into the ala, leaving a small triangular area between them which contain the septal angle (weak triangle of Converse). Laterally, the oval-shaped cartilage is connected with dense fibro-fatty tissue to the piriform aperture. This area is called the hinge area. Small segments of cartilage (sesamoid cartilages) can be found in this region. The tip-defining point (highest projecting point) is usually associated with the transition of the medial and lateral crus (or angle). Size, shape and resilience of the medial as well as the lateral crus form the third major support mechanism of the nasal tip. Other minor supporting factors are: – The strong ligamentous attachment of the skin to the interdomal region. – The cartilaginous and membranous nasal septum. – The sesamoid complex extending the support of the lateral crura to the piriform aperture (hinge area). – The anterior nasal spine .

1.2.6 Nasal Septum The septum separates the two nasal cavities, provides structural support for the nose and influences airflow in the nasal cavity. The septum is made of a sagittal plate of cartilage and bone covered by respiratory mucosa. The membranous septum connect the columella to the quadrangular cartilage, the quadrangular cartilage comprises the majority of the anterior septum. The perpendicular plate of the ethmoid bone forms the bony upper one-third of the nasal septum and the Vomer makes up its bony postero inferior portion. Finally, the nasal frontal, maxilla, and palatine bones each contribute nasalcrests to the periphery of the septum.(9)

7

The internal and external carotid arteries supply the nose via branches which anastomose extensively within the lateral wall, septum and across the midline. The external carotid artery supplies the nasal cavity via facial and maxillary branches. The facial artery supplies the most anterior part of the septum (nasal septal rami of the superior labial artery), the vestibule (lateral nasal artery) and a small area of the nasal cavity (ascending palatine artery). The maxillary artery supply is via the sphenopalatine and greater palatine branches. The greater palatine artery supplies the anteroinferior part of the nasal floor and septum .The internal carotid contributes the anterior and posterior ethmoidal branches of the ophthalmic artery. (10) 1.2.8 Nerve Supply The sensory innervation of the nose is supplied by the first two divisions of the trigeminal nerve. The supratrochlear, infratrochlear, and external branches of the anterior ethmoid nerves (VI) provide sensation to the upper, dorsal, and nasal tip surfaces, whereas the infraorbital nerve (V2) supplies sensation to the side walls Internally along the lateral nasal wall, the anterior and posterior ethmoidal nerves provide sensation to the upper portions of the nasal cavity. The sphenopalatine ganglion (V2), which originates at the end of the middle turbinate, provides innervation throughout the posterior nasal cavity branches from anterior and posterior ethmoidal nerves and sphenoplatine nerves cross over superiorly and posteriorly to provide sensation to the majority of the septum.(11)

1.3 Literature Review of Tip Plasty: The earliest descriptions of total nasal reconstruction come from ancient India during the Vedic period, approximately 3000 BC. The first detailed description of nasal reconstruction and Rhinoplasty is found in the Indian medical treatise Sushruta Samhita (700 BC). (12) Despite the advances in instrumentation and techniques through the years, Fomon’s statement in the early part of the 20thcentury, “He who masters the tip, masters rhinoplasty,”remains valid today.(13) From 1935 to 1980, the nasal tip surgery consisted of excising, incising or dividing alar cartilages. The first results were usually amazing, but hematoma, boron narrowing and collapse of external valve used to gradually occur, especially under a thin skin. The alar cartilage division was the fatal failure of the technique, because it takes to a loss of support and subsequently results in breaking the soft tissue, retraction of the alar rimas and tip clamping. These noses, with their “operated appearance” take the nasal surgery to the era of grafts. Anyway, along with the inherent changeability of structural grafts for a contour, there is always a risk for extrusion, distortions and externally apparent abnormalities. To relive such graft disadvantages, the sutures to modify the alar cartilage were adopted in the late 1980’s. MCCOLLOUGH and ENGLISH and TARDY and CHEN, by using an endonasal approach, introduced the concept of tip approximation with only one suture through 2 intermediate and lateral crurals.(14) The last 2 decades of the century were marked with a rapid switch in ideology among rhinoplastic surgeons with more emphasis on suture to reshape nasal cartilage. This allowed preservation of natural support mechanisms between

9

cartilaginous components that were routinely disrupted with the aggressive resection approach. Over 9 different suture techniques having been described to control tip position alone, although the overall premise underlying these techniques remains the same.(15) 1.4 Physical Examination The physical examination identifies correctable nasal deformities and is used to determine whether the patient's goals and expectations are realistic. The surface anatomy of the nose directly reflects the underlying framework. A systematic, detailed examination provides the surgeon with a list of problems; he formulates the operative plan, accordingly. Examination should begin with a full facial analysis to assess facial balance and the potential benefit of adjunctive procedures. Next, the nasal structures are observed. Skin thickness and texture, nasal deviation, shape and width, alar rim morphology, tip definition, projection and rotation, nasal base width, and nostril shape should be thoroughly analyzed and documented.(16) The internal nasal examination includes dynamic maneuvers such as the Cottle test and the use of topical vasoconstrictors; it is essential for assessing and documenting the preoperative status of the functional airway and for discussing the potential strategies for altering nasal relationships and improving nasal airflow and nasal appearance (spreader grafts and dorsal width). Adequate lighting and instrumentation are requisite. The internal examination should be performed before and after vasoconstriction of the nasal mucosa. Identification of preexisting synechiae, septal deformities, or perforations should be reported to the patient preoperatively to avoid mistaken blame later. Assessment of cartilage donor sites (especially in secondary rhinoplasty patients) is made when necessary to allow 10

preoperative discussion and justification of distant graft sites. Abnormalities of the septum or turbinates are presented to the patient to allow discussion of surgical correction. (16)

1.5 Digital Photographic Analysis: Photographic analysis is a key component of the secondary examination. Subtle asymmetries and deformities are more easily identified on quality photographs. Photographs also provide a significant contribution to the medical record by documenting the preoperative and postoperative status of the patient. Good quality photographs depend on proper positioning, cameras, lenses, and flashes. Every effort should be made to standardize techniques for the purpose of comparison between visits. Both traditional films and digital photographs are acceptable, although digital formats allow for easy storage and retrieval and eliminate the expense of film and development. The images are then stored in a database to allow for high-quality printing, image manipulation, and retrieval.(16) The following standardized views are obtained and analyzed in all patients: 1. Anterior (frontal) 2. True lateral (right and left) 3. Oblique (right and left) 4. Basal (high and low) 5. Top view (Helicopter view) Routinely the following views are taken: 1. Anterior (frontal) 2. True lateral (right and left) 3. Basal. Photographs also serve as useful visual aids in the communication process between patient and surgeon. The multiple-view photographs may allow patients a 11

chance to more accurately demonstrate their concerns, improving the surgeon's comprehension of the patient's goals and expectations. The surgeon may also use photographs to demonstrate qualities that the patient cannot appreciate such as asymmetries and disproportions seen in the lateral, basal, and bird's-eye views. Photographs from other patients may be used to demonstrate limitations and complications of the procedure. Facial disproportions should be pointed out to the patient to demonstrate that some asymmetries may not be corrected by the surgery or that additional procedures (for example, orthognathic surgery/genioplasty) may be necessary to accomplish the patient's goals. (16) 1.6 Aesthetic Analysis: Complete facial proportions must always be considered, because the nose occupies a central position in the overall facial aesthetics. Aesthetic nasal/facial analysis in the rhinoplasty patient is based on the relative proportions of each aspect of the face. Balanced or harmonious facial proportions are consistent with an aesthetically pleasing overall facial form. The typical proportions of a white female are used as a reference because this is the patient type most commonly seen. Variations for males are noted as appropriate (16).

1.7 Aim of the Study: To evaluate the effectiveness of using 4-suture technique to control nasal tip dynamics including (tip shape, tip symmetry and tip definition point). The four sutures include a medial crural suture, bilateral intradomal suture, and an interdomal suture.

12

Figure (4). The face is divided into thirds by transverse lines adjacent to the mentum, sub nasal, and brow at the level of the supraorbital notch and the hairline. The upper third is the least important for purposes of nasal/facial analysis because its dimension will vary with the position of the hairline. The lower third is divided into an upper third and a lower two thirds by a transverse line between the oral commissures. A transverse line through the labial mental groove divides the distance from the stomion to the menton in a 1:2 ratio. (16)

13

Figure (5). A natural horizontal facial plane is determined by drawing a line perpendicular to a plumb line superimposed over the head with the eyes in straightforward gaze. This may or may not correspond to Frankfort's line(16)

Figure (6). Attention is now directed specifically to the nasal form. Any sign of nasal deviation is identified. A line is drawn from the mid glabellar area to the menton. It should bisect the nasal ridge, upper lip, and Cupid's bow. In patients with a normal occlusion, the midline is the vertical line that passes between the two central incisors.(16) 14

Figure (7).The nasal dorsum is outlined by two slightly curved divergent lines extending from the medial super ciliary ridges to the tip-defining points. The width of the bony base is measured. It should be 75% to 80% of the normal alar base. If the bony base is wide, however, mobilization of the bones may be required to narrow the dorsum. (16)

Figure (8).The width of the alar base should be approximately the same as the intercanthal distance. If the interalar width is wider than the intercanthal width, it must be determined whether this is caused by increased interalar width or alar flaring. The normal degree of alar flaring in the Caucasian female is 2 mm wider than the alar base. If it is more than 2 mm, then alar base resection should be 15

considered. This should be distinguished from increased interalar width. If the interalar width is excessive, then nostril resection may be indicated. (16)

Figure (9).The basal view of the columella and the outline of the nasal base should form an equilateral triangle. The lobular portion of the nose and the columella should have a 1:2 ratio. The nostril should have a slight teardrop shape with the long axis from the base to the apex in a slight medial direction. (16)

16

Figure (10).On the lateral view, the position and depth of the nasofrontal angle should be noted. The deepest portion of the nasofrontal angle should lie between the upper eyelash line and the supratarsal fold with the eyes in natural horizontal gaze. No assessment of the nasofrontal angle has been made for its angle and depth, although the distance from the cornea to the nasal/facial angle has been suggested. The aesthetic nasal dorsum lies approximately 2 mm behind and parallel to a line from the nasofrontal angle in females but is slightly higher in males. (16)

17

Figure (11).This gives the nose more definition and distinguishes the dorsum from the tip. When the nasal tip projection and dorsum are evaluated, the degree of supratip break should be assessed. A slight supratip break is preferred in women but not in men. (16)

Figure (12). Tip projection is now assessed. A line is drawn from the alar-cheek junction to the tip of the nose. If 50% to 60% of the tip lies anterior to the vertical line adjacent to the most projecting part of the upper lip, tip projection is normal. If it is more than 60%, the tip may be over projecting and require reduction. (16)

18

In the lateral view, this aesthetic triangle relates the major aesthetic components of the face by soft tissue angles and lines. The normal ranges for the various angles are: – Nasofrontal (NFr) 115–130 degrees – Nasofacial (NFa) 30–40 degrees – Nasomental (NM) 120–132 degrees – Mentocervical (MC) 80–95 degrees. (16)

1.8.1 Nasal Tip Sutures: 1- Interdomal Suture: Purpose: This suture is used to reduce the distance between the domes. Indications: It is used when the domes are too far apart. Technique:A 5-0 PDS suture is placed in such a manner that the knot willend up underneath the domes. This suture can be placed as a simple loop orin a figure-ofeight fashion. A loop stitch (Fig. 14) may overlap the domal cartilages, while the figure-of-eight suture will not only avoid this but, if the domes are overlapping or are misaligned cephalocaudally,will align them. Effects: While the main objective of this suture is to reduce the distance between divergent domes, depending on where the suture is placed, additional changes may be observed. If it is placed along the cephalic border of the domes, it may slightly rotate the lateral crura cephalically. If it is placed caudally, the effect will be reversed and it will rotate the lateral crura caudally. A suture that is placed in the center will merely reduce the distance between the domes without any rotation of the lateral crura. If the suture is passed further laterally along the anterior surface of the domes, as it is tied, it will borrow from the lateral crus and add to the central dome, thus gaining more tip projection and reducing the convexity of the lateral crus. The result is a more unified and commonly narrower tip. This variation of the interdomal suture only benefits patients who have a boxy,yet under projected tip. This suture, in addition to narrowing the interdomal distance, will strengthen the tip support, achieve more lobule volume, reduce the overall tip width and eliminate any clefting that may exist between the domes. (18)

21

2- Transdomal Suture: Purpose: The goal is to reduce the width of the domal arch. Indications: This suture is useful for patients with wide domal arches. Techniques: Although a single suture can be passed across both domes and tied in the center, because there is commonly disparity in the thickness of the lower lateral cartilages and the domes, the thinner dome may respond to suture force more than the thicker dome, resulting in unequal narrowing. It is therefore preferable to place an independent transdomal suture across each dome. The suture is started from the medial aspect of one dome, passed across the dome without violating the lining and through the lateral portion of the dome, and then brought back across the dome and tied in the medial side of the dome (Fig. 15). Effects: Depending on where this suture is placed, the lateral crus may respond differently. If the suture is off center caudally, it will rotate the lateral crus caudally. If the suture is placed cephalically, it will rotate the lateral crus cephalically. A centrally positioned suture will reduce the domal width without rotation of the ala. In most cases, this suture will result in a slight cephalic retraction of the caudal border of the dome and thus retraction of the infra tip lobule. The additional consequences of the transdomal suture are increased projection of the dome, flattening or concavity of the lateral crus and reduction in interdomal distance. (18)

3- Anterior Medial Crura–Septal Anchor Suture: Purpose: The purpose of this suture is to suspend the medial crura from the anterocaudal septum to gain more tip projection. Indications: This suture is indicated on patients who have an under projected tip with a short columella. Technique: The medial crura or the footplates are minimally dissected through a transfixion incision (Fig. 16). A 5-0 nylon suture is passed through the footplates or medial crura and tied gently. The same needle is passed through the anterocaudal 23

septum. As the suture is tied incrementally, one can observe the repositioning of the entire basal unit anteriorly. It is important to tie the suture after it is passed through the footplates and before it is passed through the anterocaudal septum to avoid overlapping or separation of the footplates and riding on the caudal septum. The suture can also be placed directly between the cephalic portion of the medial crura and the caudal septum. However, its stability will not be as enduring. Effects: As the suture is tied, the tip projection will increase, the domes will separate, and the tip becomes wide and rotates cephalically. This suture will also result in elongation of the columella and the nostrils.

4- Posterior Medial Crura–Septal Anchor Suture: Purpose: This suture is used to reposition the medial crura and footplates posteriorly. Indications: This suture is indicated in patients who have an over projected tip with a long columella. Technique: The medial crura or the footplates are minimally dissected through a transfixion incision (Fig.17). A 5-0 nylon suture is passed through the footplates or medial crura and tied gently. The same needle is passed through the caudal septum posteriorly close to the anterior nasal spine. As the suture is tied, one can observe the repositioning of the entire basal unit posteriorly. Here as well, it is important to tie the suture after it is passed through the footplates to avoid overlapping or separation of the footplates and riding on the caudal septum. Effects: As the suture is tied to pull the tip and columella posteriorly, the distance between the domes will become narrower and the tip will rotate caudally. This suture will also result in reduction of the columella length and shortening of the nostrils.

1.7.2 Complications of Suture Techniques: While extremely effective, suture techniques can result in complications or suboptimal results. Keen observation of the effects of the sutures during their placement is extremely important to prevent displeasing consequences. One of the most common adverse effects of suture techniques is excessive tip narrowing due to unification of the domes. This can happen without the use of an interdomal suture and can also result from placement of other sutures such as transdomal, lateral crura spanning, lateral crus convexity, and medial crura sutures. If this occurs, a subdomal graft can be utilized to overcome the excessive narrowing of the interdomal distance. Another undesirable consequence of suture techniques is alar retraction. This can be reduced by careful observation and by insuring that the tightening of the sutures is only enough to serve the purpose without causing ill effects. However, even under 26

the most ideal circumstances, alar retraction is a common possibility after cephalic trimming of the lower lateral cartilages, as well as after placement of some of the sutures as mentioned above. In order to overcome this displeasing effect, an alar rim graft can be placed in the majority of such noses. Other adverse events related to suture techniques include infection, rejection, and palpability. Infection is a highly unlikely complication and the use of absorbable sutures has further reduced the chance of late suture infection. As indicated earlier, suture-related infection is minimized with use of non absorbable sutures. Suture extrusion is unlikely and is usually the consequence of placing the suture too close to the skin or the nasal lining. .(18)

Patients and Methods 2.1 Study Design and Setting An experimental prospective, observational (follow up) study was conducted on 54 patients who underwent open rhinoplasty in (ENT ,Head and Neck SurgerySulaimani Teaching Center ) and (Azmar Private Hospital) from 1st Jan 2016 - 1st Sept 2016. 2.2 Sampling: The study was conducted on 54 patients (14 males and 40 females) aging between 18-54 years. Preoperatively detailed history was taken from each patient who was assessed for functional, aesthetic complaints and desire of the patient. Examination started by inspecting the face for analyzing the facial components and relation of the nose to other facial components, diagnosing any asymmetry. More specific abnormalities in the shape of the tip of the nose and various disfigurements such as bifid, bulbus boxy were inspected. Also for asymmetry of the nasal tip, over projection or under projection .Skin (thickness and elasticity), nasal skeleton assessed by palpation , tip support was assessed by (tip recoil), and any deformity of external nasal valve was assessed . Internal examination of the nasal cavity was done to examine the state of mucosal lining, septum, internal nasal valve assessment and condition of turbinates. Nasal patency assessed by cold spatula test, cotton strip test, cottle test, Palpation for the caudal part of the septum and its relation to the nasal spine was done. All patients were assessed according to the follow questionnaire which is shown in the appendix. Routine preoperative investigations were done which included hematological and biochemical investigations for all patients (CBC, Blood group and Rh, Blood 28

urea, Bleeding time and Clotting time), viral studies to exclude hepatitis, and other specific investigations were done accordingly. Preoperative consent for operation was taken. Pre-operative photographs were taken for each patient (4 different views) frontal, basal, lateral, right, and left. The results were judged by an independent observer with respect to preoperative tip characteristics by comparing preoperative and postoperative photographs. Results were judged with respect to 3 variables, which are: 1. Tip shape (triangular vs boxy vs bulbous) 2. Tip definition and presence of tip defining points 3. Tip symmetry Each patient was assigned a score of -1, 0, or +1 for each of the 3 characteristics above, as the preoperative and postoperative photographs were compared. These scores corresponded to ( -1) if a postoperative result was worse than the preoperative appearance. Scores corresponded to (0) if a postoperative result was equal to the preoperative appearance. The result was (+1) if postoperative result was better than the preoperative appearance. Cumulative scores, which represented the sum of the individual variable scores for each patient, were calculated. Therefore, a cumulative score of (+ 3) indicated an improvement over preoperative appearance in all of the above 3 categories. Conversely, a cumulative score of (-3) represented a postoperative worsening in all 3 categories. Average scores for each variable were also calculated. This allowed judging effectiveness of the 4-suture technique for each of the above variables.

The table -3 -shows the effectiveness of the 4-suture technique with respect each of the 3 variables in primary open rhinoplasty. The numbers in columns 1 and 2 represent the mean score with respect to each variable. A mean score for tip symmetry was 0.79 for a mean follow-up period of three months on the -1 to +1 scale, and 0.9 for a mean follow-up period of six months on same scale of -1 to +1, it means tip symmetry was improved as preoperative photography was compared to post operative one by an independent observer. A mean score for tip definition point was 0.75 for a mean follow-up period of three months and 0.85 for a mean follow-up period of six months on the -1 to +1 scale, it means tip definition point was improved as preoperative photography was compared to post operative one by an independent observer. A mean score for tip shape was 0.68 for a mean follow up period of three months and 0.76 for a mean follow-up period of six months on the -1 to +1 scale, it means tip shape was improved as preoperative photography was compared to post operative one by an independent observer. Overall average score of 2.22 on the -3 to +3 scale, and a mean follow-up period of 3 months. And overall average score of 2.51 on the -3 to +3 scale, and a mean follow-up period of 6 months, shows the overall improvement in all of three variables as compared pre and postoperative photography of operated cases including in this study by an independent observer. The results were highly significant as shown in table - 4 -.

4.1 Discussion Nasal tip surgical procedures frequently involve manipulation of the lower lateral cartilages, so success with surgical treatment of the nasal tip is enhanced by in-depth insights into the behavior of the lower lateral cartilages . Modern nasal tip surgery, is founded on the philosophy that suture placement does not simply secure partially excised sections of alar cartilage; rather it aims to directly reshape and reposition the various nasal tip components. It is crucial to understand the goals for which the sutures are placed. The effects of sutures depend largely on the magnitude of suture tightening, the intrinsic forces on the cartilages, cartilage thickness, and the degree of soft-tissue undermining. It is also important to note that the sutures cannot be used interchangeably; each suture has a specific purpose, although some seem to be providing the same effects.(20) Nasal tip dynamics involve many properties of tip such as (tip projection, tip rotation, tip symmetry, tip shape, supra tip break, columellar double break, tip definition point) which can be controled and improved by variety of procedure such as cartilage resection, grafting and suture technique which can be used as single, but mostly used as combination procedure for controlling tip dynamics with predominant effect of one procedure on others. In the current study, suture technique was used as dominant procedure with minor contribution of other procedure for controlling of (tip shape, tip defining pint and tip symmetry), as other properties of tip such as (tip projection, rotation, supra tip break, double columellar break) can be controled by grafting and cartilage resection with minor contribution of suture technique. Gruber and Friedman(21) outlined several fundamental principles governing suture techniques including: 1) Leaving at least 5 to 6 mm wide strip of alar rim; 2) Change in shape of 1 suture-modified nasal cartilage unit with modification of other nasal components; 3) Usage of an anatomic nasal model intra operatively to judge intra operative nasal dimensions against ideal values; and least importantly; 49

4) Using appropriate suture type and size. Furthermore, Gruber and Friedman (21) described a 4-suture technique similar to the one described above to adjust tip shape in primary, open, revision, and closed rhinoplasty. Open rhinoplasty affords direct visualization of all nasal cartilages. Separating the cartilaginous framework from the soft tissue envelope leads to unpredictable contracture of the soft tissues. This “shrink-wrap” effect can be minimized by providing adequate underlying support mechanisms. This is one of the most pressing reasons to preserve as much of the native support mechanisms in the nose as possible. Resorbable suture materials such as polyglactin , polydioxanoe suture, and polyglycaprone are good for holding the cartilages in approximated position long enough for the scar tissue to take over. However, Polydioxanone is a better choice because it has long lasting tensile strength with a good knot-holding ability.(22) This study describes a 4-suture technique, which employs a medial crural suture, bilateral intra domal sutures, and an interdomal suture to manipulate tip position and shape. The medial crural suture acts to break up the natural contour of the crura from a curve into 2 distinct lines that meet at an angle. It does this by fixating these cartilages to the anterior border of the columellar strut at a precise point. By preventing splay of the dome cartilages, the intracrural suture controls tip shape, and the boxy tip is avoided. The 2 intradomal sutures are instrumental in commanding tip shape, rotation, and definition. These sutures will convert obtuse domal angles into acute ones, thereby preventing a bulbous appearance on basal view. The surgeon has license in the location of suture placement, and may create the new dome at any point along the cartilage that is appropriate.(23)

The tip defining point correspond to the caudal borders of the dome cartilages. Therefore, as the intradomal sutures make the domal angle sharper and stronger, the tip defining cartilages are brought into greater relief and tip definition is improved.

50

The interdomal suture completes the parallelogram—strengthening the tip complex, insuring symmetry and providing for a supratip break. By bringing the cephalic edges of the domes together, one prevents the tip from appearing too blunt on profile. The suture also causes the cephalic edges of the lateral crura to medialize slightly, obviating the need force phalic trim in many cases. This effect has a positive influence on tip definition, by bringing the caudal borders of the domes into greater prominence relative to the cephalic border. (24) In the current study, 40 (74.1%) of the cases were female,14 (25.9%) were male, and age ranged from 18-54 years old, mean age for operation was 27.56 years, it was found that female are more seeking for doing Rhinoplasty involving tip plasty than male. This result was contradict with Jang, T., Choi, Y., Jung, Y. et al. Jang 2007 (25) , as they reviewed of 85 patients (56 men and 29 women) with preoperative and 6-month postoperative photographs were analyzed. The mean age of the patients was 33.1 years (range, 16-65 years). The gender ratio shows that in Kurdish society female more seeking for beauty, and want more attractive nose, but males with more deformities are seeking for realignment. The current study results demonstrate that the 4-suture technique is effective in controlling nasal tip position and dynamics with respect to the 3 variables above. The overwhelming majority of the patients photographs reviewed was primary open rhinoplasty patients. The majority of primary rhinoplasty patients had favorable postoperative outcomes. The mean overall score among primary rhinoplasty patients was 2.2 after three months of follow up, and 2.51 after six months of follow up, it was found that this technique overall did not worsen the postoperative rhinoplasty result with respect to any of the 3 variables. In addition, the 4-suture technique is more effective at ameliorating some of the 3 variables than others. Namely, it is more effective at improving tip symmetry. The same result was obtained by Leach and Athre 2006. (26)

The mean values of scores for the tip symmetry were 0.79 after three months post operative assessment, and 0.90 after six months post operative follow up. The result

51

was obtained by Leach and Athre 2006, for tip symmetry was 0.85, for the mean follow up period of 3.8 month (26). In this study, skin thickness is a determining factor in the effectiveness of the four sutures. Results are more significant in patients with thin skin and sparse subcutaneous tissue. However, the suture techniques have less significant effect in patients with thicker skin and excessive subcutaneous tissue. The same result was described by Pasinato et al 2012.(27)Also the same result was obtained by Baker SR. 2000. (12) Also the same result was proven by Nassif Filho 2011.(14) The results found in this study were satisfactory from both patients and surgeon’s standpoints, and the overall aesthetic improvement was satisfactory. The same result was obtained by Vuyk HD 1993.(13) and also by Nassif Filho 2011.(14) The major limitation this study is the short period of follow-up, as it was well known that the last results of rhinoplasty are best to viewed several years after because it was found that scar contracture and aging may alter the shape of the nose in the long period, showing bossae, retractions, notching, and asymmetry. We are hopeful that this long period results will be satisfactory for many reasons: as cartilage resection and weakening was minimized in four suture technique that we used, a sutured-in-place columellar strut were used, and the 4 long-lasting sutures used provided empowerment to the cartilages rather than weaken them. In this study major complications such as infection, stitch extrusion, or suture breakage were not found.

52

5.1 Conclusions: Four suture techniques are powerful tools for controlling tip symmetry, tip shape, and better alignment of tip definition point, and improve overall aesthetics and natural appearing results of nose. So the 4-suture technique is a useful tool to be added into the armamentarium of the rhinoplastic surgeon.

5.2 Recommendations: Further conducting studies and taking larger number of cases are recommended for better assessment to demonstrate the effectiveness of this technique in long-term follow up. The 4-suture technique may not be satisfactory for some known rhinoplasty patients, particularly those with intrinsic weakness of the cartilage and relatively thick skin-soft tissue envelopes. In such cases, other technique may be more effective in improving tip strength and definition.
