Maxillomandibular advancement (MMA) surgery is indicated for severe sleep apnea. Dr. Pasha does not perform this type of surgery but he may refer you to a maxillofacial surgeon if he feels you may benefit from this advanced operation. During this procedure the upper jaw (maxilla) and lower jaw (mandible) are moved forward to open the airway in the back of your nose and throat using plates and screws. MMA surgery may be suggested if you continue to have severe sleep apnea after other procedures have failed. It is also performed in patients with significant jaw deformity contributing to obstructive sleep apnea.
This procedure is performed in a hospital surgery center under general anesthesia and lasts three to four hours in duration. Hospitalization is usually two to three days and in general the patient can return to work in four weeks. Chewing is avoided for four weeks. Neither speech nor swallowing is affected but this procedure is associated with pain and temporary numbness of the lower lip and chin. Some changes in facial appearance may occur but is usually quite acceptable.
