Transcutaneous and Transmucosal Serdev Sutures ® for Nasal Tip Refinement, Alar Base Narrowing, and Other Corrections

The author describes his experience with the transcutaneous Serdev Suture ® techniques in different aesthetic disproportions of the external nose and in secondary cases. Author’s needles are specifically designed for these techniques. Rhinoplasty is part of the beautifi‐ cation process. The cosmetic surgeon should be guided by correct nose proportions, an‐ gles, and volumes. Proportional nose is one that fits in 1/3 of the face length. Proper volumes are: thin dorsum, thin tip, narrow alar base. The tip of the nose prominence gives volume to the central face and its position should be in harmony with the beauty triangle (projected cheekbones and chin). The tip should be in the line of the cheekbone prominences. The nasal dorsum should be straight or slightly concave. The best angles are: 90° angle at the tip, 110° nasolabial angle, 30° angle of nostrils to columella, 30° dor‐ sum to profile line. The aim of Serdev Suture ® techniques in beautification rhinoplasty is to improve the above-mentioned aesthetic proportions, volumes, and angles of the nose, adapted to the face as a whole. Serdev Sutures ® in rhinoplasty include: tip rotation, re‐ finement of the tip, lower and medial thirds, alar base narrowing and nasal dorsum lift‐ ing of concavities and irregularities.

Earlier rhinoplasty techniques were based on closed or open operative procedures with combinations of incisions, approaches, and tip altering maneuvers, cartilage separation and their treatments, which are followed by some not very rare complications, such as tip deformation, destabilization of the nasal framework, and nasal tip support. Later, radical cartilage resections have been replaced by reshaping and reorienting of the nasal tip components. Intraoperative suture techniques of the nasal tip in open surgery became popular with McCollough and English double-dome unit procedure to increase tip projection and refinement using a horizontal mattress suture through all 4 crura just beneath the domes; with Goldman tip procedure for the wide or bulbous lobule, with Daniel domal creation suture, a horizontally placed mattress suture, which shaped each dome separately. Numerous suturing techniques appear in the literature regarding open technique rhinoplasty. All subcutaneous suture techniques listed above are used in open surgery [18][19][20][21][22][23][24][25][26][27][28][29].
Serdev Sutures ® techniques represent scarless transcutaneous or transmucosal closed approach techniques. They could be: 1) transcutaneous methods to refine the tip or narrow the alar base; 2) transmucosal medial crura mattress sutures for tip refinement, columella sliding, and columella stabilization; 3) refinement sutures of projected lateral crura; and 4) sutures of fibrotic tissue or greater cartilages to lift depressions on the dorsum -primary or secondary. Thus, narrowing of the tip and alar base, and cartilaginous lower and medial third of the nose, etc., could be obtained. Author's needles ( Figure 1) and Polycon semielastic surgical sutures guarantee the atraumatic nature of the procedure and better healing process. One of the important qualities of Serdev® needles is that they create a round skin perforation point and allow for easy prevention of dermis fixation during the second needle pass that completes the circle of the suture. This is an advantage over cutting needles, which create a linear skin perforation that may result in capturing dermis, and must be avoided. The result when using other needles is dimpling, which is impossible to remove.
Stable results also depend on the suture material. Thin, monofilament threads can cut through the fine nasal cartilages, especially if the latter are mobile. Polycon, braided, semielastic USP 3-0 sutures, used by the author, protect the sutured cartilages and ensure the longevity of the result.

Anatomy
The alar cartilages define the nasal tip. Their three crura (medial, middle, and lateral) and their junctions are of main aesthetic importance. The medial crus forms the columella and its support. Wide distance between the medial crura makes the tip look bifid or wide, depending on thin or thick soft tissue and skin. The middle crus has a lobular and a domal segment. The normal divergence angle between lobular segments should be close to 30°. Both divergence and domal angle can form a wide tip. The length of the lobular segment is also responsible for the tip shape.

Indications for nasal tip, medial and lower third refinement via Serdev Sutures ®
Indications are specific wide tip deformities: bifid tip with a dimple between the two tips, bulbous tip with flat domal segment and broad convex lateral crura; boxy tip with rectangular shape; ball tip with alar cartilages, which are too large and convex; bulky tip with thick skin, too heavy in comparison to the rest of the nose.

Transcutaneous suture for lifting of all 4 crura or only medial crura of greater alar cartilages with fixation to the periosteum of the nasal bones
Two lines of the suture are important: 1) a pass under the nasal bone periosteum, which represents the immobile fixation, and 2) a subdermal pass in the columella, holding the mobile medial crura or all 4 crura of the greater alar cartilages -their suture rotation will shorten the nose. Two connecting subdermal passes fulfill the circle of the suture. The suture dives without engaging skin in each skin perforation point ( Figure 2).

Surgical technique
The needle and suture are introduced through the following planes: The pass A-B is subperiosteal (50 mm Serdev ® needle is used). A1-A and B1-B are subdermal connecting passed (60   B. Using one skin perforation point in the middle of the columella, just below the dome, the first connecting needle pass is done to lift the left greater alar cartilage dome with fixation to the nasal bone periosteum. The needle reaches the left-side skin perforation point B at the level of the subperiosteal pass. The needle is loaded and the suture will be introduced in line B-C subdermally C. Using the same skin perforation point in the middle of the columella, just below the dome, the second connecting needle pass is done to lift the right greater alar cartilage dome with fixation to the nasal bone periosteum. The needle reaches the right side skin perforation point A at the level of the subperiosteal pass. The needle is loaded and the suture will be introduced in line A-C subdermally D. Suture is tied to slightly overcorrect the position of the nasal tip. E.

Tip refinement using transcutaneous transdomal suture of all 4 crura
A 50 mm curved semielastic Serdev ® needle and semielastic Polycon sutures USP 3-0 are preferred for these specific delicate cartilages. They have prolonged absorption (2 years, i.e., after final fibrosis is obtained and foreign materials are no more necessary). Rigid and thin threads can perform like scalpels and cut through cartilages. Nonabsorbable sutures are potential foreign bodies for late complications (infection, foreign body reaction, and extrusion). Early absorbable suture material disappears sooner than needed.
Author's transcutaneous sutures do not engage skin. The direct contact between cartilage surfaces in suture techniques stimulates fibrotic formation, which guarantees the stability of the result.
There is a selection of variation in each technique, modifications or combinations of techniques. For tip refinement, the author mostly uses the transdomal technique of suturing all 4 crura.
This method is very effective for narrowing the tip. It could be also used to additionally increase the tip projection. Skin perforation points are usually positioned the level of the tip point on either side, to insert a horizontal mattress suture through all 4 crura subdomally. It is a double dome suture ( Figure 5) to narrow the tip by bringing the domes together.

Surgical technique
The transdomal suture uses 2 skin punctures and consists of 2 needle passes, without engaging skin. Each needle pass uses a different but parallel path through the cartilages. The transcutaneous suture is diving, buried below the skin. It attaches only cartilages, without including dermis in the suture. Skin and its perforations can be moved up and down the cartilages to obtain a distance of 2-3 mm between the parallel passes. Both needle passes have to be placed in the domal area without perforating the nostril in order to prevent contamination and compromising the result. The suture could be placed 3-4 mm posterior to the dome, to preserve the separation between the domes in front. The knots should be tied under elastic tension.

Clinical cases
The transcutaneous transdomal suture could be applied as a separate technique or as a part of primary or secondary rhinoplasty. It is simpler and safer than subcutaneous sutures in open rhinoplasty and their sequellae. It closes the divergence and dome angles atraumatically, thus saving time during operation, and shortens recovery.

Tip refinement using transmucosal domal suture of medial crura
This method is usually combined with the author's closed rhinoplasty techniques, such as Texcision and columella sliding. The suture should be placed as high as possible to fix the domal medial crura. There is no need for this suture to be buried below the nasal mucosa, which is involved on each side in the transmucosal mattress suture. Using absorbable sutures, the fibrosis stabilizes the effect after the first 3-4 weeks. If suture is not absorbable, it has to be removed after 3 weeks.
Medial crural fixation suture is used to fix the medial crura and to close the divergence angle between lobular segments of medial crura. This suture can refine the tip in cases of an open divergence angle of medial crura and normal domal angle. If the domal angle is more open, then the medial crura fixation suture can be an additional correction. The suture gathers the Skin and its perforations can be moved up and down the cartilages to obtain a distance of 2-3 mm between the parallel passes. Both needle passes have to be placed in the domal area without perforating the nostril in order to prevent contamination and compromising the result. The suture could be placed 3-4 mm posterior to the dome, to preserve the separation between the domes in front. The knots should be tied under elastic tension. The suture should be placed in the domal tissue only. Be careful not to enter through the nostril as this will cause suture contamination. Dermis should not be engaged in order to prevent from dimples. Dimpling will be removed using a mosquito instrument.

A horizontal mattress suture is placed through mucosa and both medial crura ( Figure 9). The domal symmetry can be adjusted with the position of the needle perforating both medial crura. If there is asymmetry of both tips, the needle pass through cartilages should be parallel to the asymmetric defining points of the tip to keep symmetry in the tip area ( Figure 1, Chapter 5).

If both sides of the tip are not equal in projection, a domal equalization of symmetry may need an additional nonhorizontal transdomal or medial crura suture.
Both suture types give good refining definition and at the same time a projection effect. In cases of bulbous tip, transdermal suture of all 4 crura is preferable. Both sutures can be used separately, combined, or as a part of a complex rhinoplasty.

Refinement of nasal lower third using lateral crura transcutaneous suspension suture
If prominent lateral crura widen the lower third of the nose, then spanning sutures are used by the author to reduce their convexity and narrow the area cephalic to the tip. The transcutaneous suture should be placed at the highest convexity area, in order to suppress it. Fixation of the suture to a higher point of the dorsal septum is used in selected cases to additionally rotate the tip.  A. B. Figure 12:A. Before. Slightly deviated aquiline long nose.

Refinement of nasal medial third using transcutaneous suture of upper lateral cartilages
This suture (author's) is useful in primary cases with wide upper lateral cartilages or mostly in secondary cases with open cartilage and bony roof after humpectomy.
In secondary cases, digital fracture of the nasal bones and sutures of upper lateral cartilages are used by the author to optimally close the open roof, project and narrow the dorsum at the nasal medial third. One or more transcutaneous sutures could be placed along the cartilage part of the nose at the medial third, lower third, and the tip of the nose for whole dorsum refinement ( Figure 14). Fixation of the suture to the dorsal septum is used in selected cases for stabilization, if necessary. This maneuver is easy, catching the dorsal septum with the semiblunt, semielastic, curved Serdev ® needles. They create a round skin perforation point and allow for easy prevention of dermis fixation during the second needle pass. This is an advantage over cutting needles, which create a linear skin perforation that in most cases leads to fixation of the dermis -the result is dimpling, which is impossible to remove.
Stable results also depend on the suture material. Thin, monofilament threads can cut through the fine cartilages. Polycon sutures, braided, semielastic, USP 3-0 protect the sutured cartilages and ensure longevity of the result.

Alar base narrowing has the additional effect of tip projection.
Deviations and deformities in cases of wide alar base could be different, depending on ethnos, protruding medial crura, deviated nasal spine, etc. (Figure 17A, B, C).

Conclusion
Serdev Sutures ® in rhinoplasty, as mini-invasive and atraumatic procedures, used separately or as part of complex rhinoplasty, show advantages over other rhinoplasty techniques. Author's techniques are time-saving, atraumatic operations with great results and complication rate lower than 0.003% [1][2][3]. Transcutaneous suture techniques have advantages over medical rhinoplasty using temporary fillers as well, because the time of procedure is the same or shorter, but the result is permanent.
