Maxillomandibular Advancement

Maxillomandibular advancement (pronunciation: max-ill-o-man-dib-u-lar ad-vance-ment) is a surgical procedure performed to treat sleep apnea and other breathing disorders.

Etymology

The term is derived from the Latin words 'maxilla' meaning jaw, 'mandibula' meaning lower jaw, and 'advancement' meaning moving forward.

Procedure

In a maxillomandibular advancement, the upper and lower jaws (the maxilla and mandible) are moved forward from the rest of the facial bones. This allows more room behind the tongue and soft palate, reducing the likelihood of obstruction and enabling easier breathing.

Indications

Maxillomandibular advancement is typically indicated for patients with severe obstructive sleep apnea who have not responded to other treatments. It may also be used in cases of certain facial deformities or malocclusions.
