Wide and sharp jaw angles are viewed as masculine features and are considered non-attractive by many women. A jaw angle resection can be performed to soften the square jaw. In some patients, enlarged jaw muscles (masseter hypertrophy) are responsible for the a wide lower face. These patients may be treated by partial resection of the muscle or by injections with Botox. Digital radiographs may be needed in addition to physical examination to diagnose the underlying cause.
The procedure is performed under general anesthesia along with supplemental local anesthesia for optimal patient comfort. Incisions are made inside the mouth to gain access to the angle of the jaws. Instruments are then used to reshape the jawbone. Incisions are closed with dissolvable sutures which remains for seven to ten days. An external pressure dressing is applied around the head which is removed on the first postoperative day.
Cheek and lip swelling is expected which may last one week to ten days. Limited mouth opening is also expected for one to two weeks. However, patients can open and chew without much discomfort. A soft diet is recommended during the healing period. Patients may resume normal activities after two weeks and strenuous exercise after three weeks
