A number of methods have been reported for reconstruction of defects after the excision of malignant tumors on the lower lip. Special interest has centered on Estlander's method, which makes triangular flaps of entire layers. The operative method is applied on a lateral part of the upper lip with a pedicle located on the median side, followed by downward transposition. The procedure can safely and easily reconstruct deficiencies in the lower lip with outstanding results. However, it requires a secondary commissuroplasty because the commissure on the affected side becomes smaller and round in shape.Several methods have been suggested for secondary commissuroplasty, but even with one of these methods, it is very difficult to create a satisfactory commissure in terms of aesthetic and functional considerations. As a new method for secondary operation, we performed the commissuroplasty with satisfactory results by forming two opposing triangular mucosal flaps in the vermilion area and a small triangular skin flap on the commissure. This method produces extremly good results, obtaining favorable commissure form and reconstruction of the mucosa of both upper lip and lower lips without an unnatural-looking color change in the mucosa or a step deformity in the vermilion.Our method could improve the results of Estlander's operations after tumor resection in the lower lip.
