commissuroplasty
Pronunciation: kom-ih-SHUR-oh-plas-tee
Surgical procedure to widen the mouth opening by reconstructing or releasing the oral commissures.
Full Definition
Commissuroplasty is a reconstructive surgical technique designed to widen the mouth opening by addressing the oral commissures (corners of the mouth). This procedure is commonly performed to treat microstomia, whether congenital or acquired from burns, trauma, or scar contracture. The surgery typically involves releasing tight commissural bands and may employ various techniques including simple commissural release, Z-plasty advancement, or local tissue rearrangement with mucosal grafts. The goals include achieving adequate oral aperture for normal function while maintaining lip competence, sensation, and acceptable aesthetic appearance. Careful planning is essential to avoid overcorrection, which could result in drooling or difficulty with lip seal.
Usage
Usage note: Specifically refers to surgery of the mouth corners; not to be confused with general lip surgery (cheiloplasty).
