What does maxillomandibular advancement involve?

Maxillomandibular advancement is a surgical procedure that involves the cutting and repositioning of the upper (maxilla) and lower (mandible) jaw bones to enhance airflow through the upper airway. This procedure is primarily aimed at treating obstructive sleep apnea by enlarging the airway space. By moving the jaws forward, the overall structure of the airway is altered, reducing the risk of airway collapse during sleep.

The advancement of both the maxilla and mandible creates a more open airway, which can improve breathing patterns and alleviate symptoms associated with obstructive sleep apnea. This method is particularly useful for individuals who have anatomical abnormalities contributing to their condition and may not respond to conservative treatments. Understanding the mechanics of this procedure is vital for anyone studying or working in the field of sleep medicine, as it highlights a surgical intervention that addresses the root cause of airway obstruction.
