Maxillomandibular advancement

This surgical procedure opens the airway behind the palate as well as behind the base of the tongue. The operation cuts the bone of the upper and lower jaw and pulls these structures forward. This is performed under general anesthesia and requires a two-day hospital stay. This type of treatment is usually done if previous procedures have not completely improved the obstructive breathing episodes and the patient has persistent symptoms of daytime sleepiness and fatigue.1
