commissuroplasty
Pronunciation: com-ih-SURE-oh-plas-tee
Surgical reconstruction or repositioning of the oral commissure (corner of the mouth) to restore function and aesthetics.
Full Definition
Commissuroplasty is a specialized plastic surgery procedure focused on reconstructing or repositioning the oral commissure, the anatomical junction where the upper and lower lips meet at the corner of the mouth. This procedure is commonly performed to correct congenital anomalies such as macrostomia (wide mouth), to address acquired deformities from trauma or tumor resection, or to improve aesthetic appearance in cases of commissural ptosis (drooping corners). The surgery requires precise understanding of oral anatomy and careful attention to maintaining proper oral competence, sensation, and natural expression.
Usage
Usage note: Single word; refers specifically to corner of mouth surgery, not general lip procedures.
