What Is "MMA"?

Maxillomandibular advancement (MMA) is a form of facial skeletal surgery that advances the jaws to expand the airway. All incisions are performed inside the oral cavity. Occasionally, there may be two inconspicuous incisions on the cheeks. 

Conditions Treated

Obstructive sleep apnea (OSA)

Occurs when a patient stops breathing during periods of sleep; usually as a result of blockage (obstruction) in the airway.


A very common condition caused by the obstruction of air into the lungs. The "extra" air gets redirected into the mouth, creating a vibration of the soft tissue of the palate.

Upper airway resistance syndrome (UARS)

A condition in which the upper airway is reduced during sleep, resulting in disturbed sleep; can lead to snoring, daytime sleepiness, cognitive impairment, un-refreshing sleep, and frequent arousals from sleep.

MMA orthognathic surgery successfully opens airway

and reduces the severity of obstructive sleep apnea by 65 to 80%
