It is well known that lower lip tumors among Japanese are rare in comparison with Europeans and Americans.<BR>Five cases of lower lip tumors (three cases of verrucous carcinoma, one case of adenoid cystic carcinoma and one case of hemangioma) were operated on by the step form method, M shape operation method and method of sliding of one side flap. These tumors were surgically removed enblock with the healthy peripheral tissue. The defects ranged from three-fifths to two-thirds of the width of the lower lip. The patients were successfully operated on by using only the lower tissue, because the lower lip has a great capacity for defects.<BR>Postoperative recovery of the function and shape were satisfactory. All patients are doing well and show no evidence of tumor recurrence.
