title: Reconstruction of Surgical Defects of the Labial Commissure.
abstract: The main objective of oncologic dermatologic surgery is the complete excision of skin tumors. During reconstruction of the defect, we must attempt to preserve function and cosmetic appearance. At the labial commissure, fibers from the superior and inferior portions of the orbicularis oris muscle intersect and the vermillion inserts onto the modiolus, a complex, cone-shaped structure at the angle of the mouth. Surgical reconstruction of the labial commissure is challenging because of the need to preserve sphincter function and cosmetic symmetry. We present a number of cases of surgical defects at the labial commissure and describe the reconstruction techniques used. We also propose an algorithm to help determine the most suitable technique for different cases.
