The airway is, in essence, confined by the upper and lower jaws. By moving the upper jaw (maxilla) and lower jaw (mandible) forward, the entire airway can be enlarged. This procedure serves as the most effective surgical treatment for obstructive sleep apnea. It is performed on patients with moderate to severe obstructive sleep apnea as the only treatment, or when other procedures have failed. It is also performed in patients with significant jaw deformity that contributes to obstructive sleep apnea.

This procedure is performed in a hospital surgery center under general anesthesia.

Maxillomandibular advancement surgery is 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.

In general, the jaws do not need to be wired after surgery as they are stabilized. The integrity of the bite is preserved through the use of small titanium plates and screws, as well as braces (or arch bars) and rubber bands. Chewing is avoided for four weeks. Speech and swallowing are not affected but this procedure is associated with pain, swelling and temporary numbness of the lower lip and chin. Some changes in facial appearance will occur but is usually quite acceptable. This procedure is occasionally performed with genioglossus advancement or nasal surgery.
