Description

Upper lip cancer is extremely rare in Japanese patients. We report a case of squamous cell carcinoma of the upper lip mucosa in a patient in whom a bilateral perialar crescentic advancement (PCA) flap and an Abbe flap were used for immediate reconstruction. The patient, a 39-year-old man, presented with a tumor (dimensions, 25×21mm) on the upper lip mucosa. A full-thickness defect caused by surgical excision of the tumor extended over two-thirds of the upper lip. To reconstruct the large defect of the lip, a bilateral PCA flap and an Abbe flap were utilized. Two weeks after the operation, the pedicle of the Abbe flap was divided and returned to the lower lip. One month after the second operation, elongation of the oral fissure and restoration of the angle of the mouth were performed. Combined use of a bilateral PCA flap and an Abbe flap for reconstruction of the large defect of the upper lip has resulted in an excellent cosmetic and functional outcome to surgery, with no clinical evidence of recurrence.
