UNASSIGNED: Macrostomia is a congenital deformity found in Tessier no. 7 facial clefts defined as an enlargement of the mouth at the oral commissure. Several techniques are described in literature to achieve optimal functional and aesthetic results, with varying results and surgeon preferences. In this case series we report surgical repair of macrostomia with a vermillion square flap method for the oral commissure combined with either Z-plasty or W-plasty closure for the skin.
METHODS: A retrospective case analysis of 12 patients with macrostomia operated over the past 7 years at our plastic surgery division was performed (by two different operators; 11 cases by A.S. and 1 case by R.S.). Clinical features of the patients were analyzed through photography documentation, and patient description such as age of operation, operation technique, and complications were obtained through patient records. Macrostomia was corrected with a vermillion square flap method for commissure, overlapping muscle closure, along with either Z-plasty or W-plasty closure for the skin. Quality of lip commissure position, symmetry, thickness of vermillion, and scar result were recorded.
UNASSIGNED: In all twelve patients repaired with the overlapping muscle closure and square flap, the lip commissures were formed with satisfactory shape, position, and thickness with no commissure contracture during the follow up period. The Z-plasty was a simpler method compared to the W-plasty, and resulted in comparable scars. One patient (adult with hemifacial macrostomia and W-plasty skin closure) underwent revision surgery for more accurate symmetry and position of the oral commissure.
CONCLUSIONS: There are many varieties of surgical repair for macrostomia, and each method should be adjusted and combined according to each patient. Overall, macrostomia repair with this technique combination produced satisfactory aesthetic and functional results in all twelve patients. Z-plasty for skin closure after muscle and vermillion closure was a simpler technique and resulted in comparable scars than W-pasty closure in this case series.

This study was conducted to see if better scar results could be obtained by administering botulinum neurotoxin type A (BoNTA) injection and W-plasty incision for preventing rhytidectomy scar.
All patients underwent extended deep-plane rhytidectomy in two groups. Group 1 had a straight incision line, and BoNTA was not given. Group 2 was injected with W-plasty and BoNTA. Photos were taken before surgery and twelve months after surgery. Two aesthetic surgeons analyzed the results using MSS, MSRS, and SBSES. Interrater reliability was measured using the intraclass correlation coefficient (ICC).
Forty-nine patients were included in the study. Group 1 (Straight incision, No BoNTA) had 26, and Group 2 (W-plasty, BoNTA) had 23 patients. The interrater reliability in Group 1 was excellent for MSS (ICC, 0.957 [0.904-0.981]), and good in two of the interrater reliability measures (ICCs, 0.897 [0.769-0.954] for MSRS, and 0.821 [0.605-0.919] for SBSES). Interrater reliability in Group 2 was good in two out of three measures (ICCs, 0.760 [0.423-0.899] for MSS, 0.746 [0.392-0.893] for MSRS, and 0.851 [0.654-0.937] for SBSES). There was a significant statistical difference between Group 1 and Group 2, showing that Group 2 has superior outcomes (MSS, 6.596 ± 1.569 vs. 5.435 ± 0.590, P = 0.001; MSRS, 4.346 ± 0.967 vs. 3.652 ± 0.510, P = 0.003; SBSES, 3.788 ± 0.695 vs. 4.261 ± 0.541, P = 0.012).
Analyzed by three dedicated scar assessments, better results were obtained through combining W-plasty and BoNTA injections, so it is expected to be a useful method for improving scars.

W-plasty is a very popular scar excisional revision technique. The core of the technique is to break up the scar margins into small triangular components, so as to cause light scattering and make the scar less noticeable. However, due to skin tension, facial incision scars tend to spread. Applying W-plasty alone cannot achieve the ideal repair effect of facial scars. In this study, we proposed a scar revision technique combined W-plasty with continuous tension-reduction (CTR) technique to improve the appearance of facial scars. Sixty patients with facial scar were comprised in this retrospective study. Scars were assessed independently using the scar scale before and at 12-month follow-up. Clinical results showed a significant difference in scar appearance between different groups at 12-month follow-up. Vancouver scar scale (VSS), visual analogue scale (VAS) scores, and patient satisfaction were significant better in W-plasty and CTR than other groups at 12-month follow-up. No severe complications were reported. The application of the tension offloading device provides an environment where the tension is continuously reduced, which could greatly decrease tension on the surgical incision. Combined with W-plasty, this technique could significantly improve the scar\'s aesthetic appearance.

Scars pose a complex challenge to the reconstructive surgeon in the variability of their presentation and their effect on cosmesis and function. Numerous surgical and nonsurgical options exist for scar management, each with their respective advantages and disadvantages. Each treatment modality should be tailored to the patient to ensure enhanced outcomes. In this review, we discuss different scar presentations, scar management options, and the benefits and risks with undergoing these various treatment modalities.

Scars are the final result of the four processes that constitute cutaneous wound healing, namely, coagulation, inflammation, proliferation, and remodeling. Permanent scars are produced if the wounds reach the reticular dermis. The nature of these scars depends on the four wound healing processes. If the remodeling process is excessive, collagen degradation exceeds collagen synthesis and atrophic scars are produced. If the inflammation phase is prolonged and/or more potent for some reason, inflammatory/pathological scars such as keloids or hypertrophic scars can arise. If these pathological scars are located on joints or mobile regions, scar contractures can develop. When used with the appropriate timing and when selected on the basis of individual factors, surgical techniques can improve mature scars. This review paper focuses on the surgical techniques that are used to improve mature scars, burn scars, and scar contractures. Those methods include z-plasties, w-plasties, split-thickness skin grafting, full-thickness skin grafting, local flaps (including the square flap method and the propeller flap), and expanded flaps, distant flaps, regional flaps, and free flaps.

OBJECTIVE: A suture line placed with the same direction as the relaxed skin tension line leads to good healing, but a suture line with over 30 degrees of angle from the relaxed skin tension line leads to longer healing time and more prominent scarring. W-plasty is widely used to change the direction of the scar or to divide it into several split scars. In this study, we applied W-plasty to patients with facial lacerations in the emergency department.
METHODS: From June 2012 to December 2014, 35 patients underwent simple repair or W-plasty for facial lacerations. Patients in the simple repair group underwent resection following a thermal margin, and the W-plasty group was resected within a pre-designed margin of W-shaped laceration. We assessed prognosis using the Stony Brook Scar Evaluation Scale (SBSES) after 10 days (short-term) and six months (long-term), respectively, following suture removal.
RESULTS: Among 35 patients, 15 (42.9%) underwent simple debridement and 20 (57.1%) underwent W-plasty. In the W-plasty group, there was no difference between short-term and long-term follow-up showing high SBSES, but in the simple debridement group, long-term follow-up SBSES significantly decreased. W-plasty SBSES was higher than simple debridement at short-term as well as long-term follow-up.
CONCLUSIONS: We experienced good results of direct W-plasty application at six-month long-term follow-up. Therefore, W-plasty application is more effective in reducing scar appearance than a simple debridement method for facial laceration patients with an angle of 30 degrees or more to the relaxed skin tension line.

Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods.

Posttraumatic soft-tissue injuries of the face are often the most lasting sequelae of facial trauma. The disfigurement of posttraumatic scarring lies in both their physical deformity and psychosocial ramifications. This review outlines a variety of techniques to improve facial scars and limit their lasting effects.

Congenital double lip is a rare developmental anomaly which usually involves the upper lip more than the lower lip. It may occur in isolation or as a part of Ascher\'s syndrome. Sometimes upper and lower double lips occur simultaneously. The occurrence of double lip may result in facial deformity especially when the patient attempts to talk, smile or even show the teeth. It may also interfere with speech or mastication. Although surgery may be undertaken to facilitate speech and mastication, the majority of cases are operated for cosmetic reasons. A case of congenital double upper lip, which was surgically treated after orthodontic treatment, for cosmetic reasons, is reported. The different surgical approaches to the management of double upper lip are reviewed with a note on timing of surgery in patients who have concurrent orthodontic or prosthodontic problems. Although the majority of cases of double lip are treated by Plastic Surgeons and Oral and Maxillofacial Surgeons, it is important to make dentists aware of this condition since they may be the first clinicians to encounter patients with this abnormality.
