Supplementary Material for: A New Concept for Central Wedge Resection in Labiaplasty

<b><i>Objective:</i></b> The aim of the study was to develop a new concept for central wedge resection to improve surgical results. Currently, the most common postoperative complications of the regular central wedge (RV) resection technique are wound dehiscence and scar contracture. <b><i>Methods:</i></b> A case-control study was applied to randomly divide 119 patients with labia minora hypertrophy deformities into 2 groups: new central wedge (NV) (<i>n</i> = 57) and RV (<i>n</i> = 62). All patients underwent the corresponding corrective surgery to repair the deformity. During the NV procedure, we changed the direction of the scalpel to form 2 inclined sections and sutured these sections together to achieve nonparallel closure lines. The patients in the 2 groups were followed up at 1 and 6 months postoperatively. We described the details of this method and evaluated the treatment outcomes of the 2 groups. <b><i>Results:</i></b> Patient age, labia minora width, and procedure time were not significantly different between the 2 groups (<i>p</i> &gt; 0.05). However, the visual analog scale (VAS) scores in the 2 groups were significantly different (<i>p</i> &lt; 0.05). Two patients in the NV group were somewhat dissatisfied because of lymphoedema and asymmetry; 6 patients in the RV group expressed dissatisfaction with scarring, healing complications, and asymmetry. A minor corrective operation was performed for asymmetry, and the dehiscence healed spontaneously. The patient with edema is still being followed up. <b><i>Conclusion:</i></b> The surgical method we introduced was indicated to be a simple and effective procedure that avoided wound dehiscence and scar contracture, which are common with the regular approach.
