maxillomandibular advancement
A surgical procedure that moves both the upper and lower jaws forward to treat obstructive sleep apnea and improve facial aesthetics.
Full Definition
Maxillomandibular advancement (MMA) is a comprehensive surgical procedure that involves the forward movement of both the maxilla and mandible. This technique is primarily used to treat severe obstructive sleep apnea by enlarging the airway space, but it also has significant applications in correcting facial deformities and improving facial projection. The procedure requires precise planning and coordination of movements in both jaws to maintain proper occlusion while achieving the desired functional and aesthetic outcomes. MMA is considered one of the most effective surgical treatments for OSA when other interventions have failed.
