Bulging of the mandibular angle is considered to be unattractive in the Orient since it gives the face a quadrangular and muscular appearance. In spite of its muscular origin, surgery should be aimed toward bony reduction or osteoplasty and supplemental myotomy. An intraoral approach was utilized with an oscillating saw to resect a predetermined segment of bone (mandibular angloplasty). In 2 patients with a prominent bilateral mandibular angle, only the bony angle was resected. The improvement of facial esthetics was subtle, and the acceptance and satisfaction of the patients were very good. A review of the literature is included with comments on the diagnosis and treatment of benign masseteric hypertrophy.
