commissuroplasty
Pronunciation: koh-MISH-ur-oh-plas-tee
Surgical reconstruction or widening of the oral commissures to improve mouth opening or correct microstomia.
Full Definition
Commissuroplasty is a surgical procedure designed to reconstruct or enlarge the oral commissures (corners of the mouth) to improve oral opening and function. This technique is commonly used to treat microstomia, which may be congenital (as in certain syndromes) or acquired (following burns, trauma, or scar contracture). The procedure typically involves releasing scar tissue and creating new commissures through various techniques including local flaps, skin grafts, or tissue rearrangement. Goals include improving access for dental care, oral hygiene, eating, and speech. The procedure requires careful attention to maintaining competent lip seal and aesthetic appearance while maximizing functional improvement. Multiple techniques exist, with selection based on the degree of limitation and underlying cause.
