Snoring and ENT Surgery For Snoring & OSA

About Jaw Advancement Surgery

Snoring and obstructive sleep apnoea (OSA) occurs when one or more levels of the upper airway become obstructed due to narrowing and/or collapse while you sleep. 

In some patients, especially those with small, retruded jaws and severe OSA, surgery to move both the upper and lower jaw forward gives the best chance of increasing the size and of reducing collapse of the upper airway behind the soft palate and tongue. The surgery is known as maxillomandibular advancement (MMA) or bimaxillary advancement. 

In contrast to all other surgical procedures for OSA, MMA improves the airway at all levels, from the nasal cavity to the area behind the tongue. The vast majority of patients, even those with severe OSA, have a successful outcome. In fact, more than half of patients achieve elimination of OSA.

While jaw advancement surgery is very effective in treating OSA, patients need to be well selected. Patients who may be recommended MMA are usually those who have been unsuccessful in tolerating Positive Airway Pressure (PAP) therapy and those who have residual OSA even after other surgical procedures

While there are several variations of MMA, the goal of the move the upper and lower jaw forward, while maintaining or optimising the way the teeth of the upper and lower jaw fit (dental occlusion) and avoiding injury to the nerves that provide sensation to the teeth and lips.
