Labial commissure of mouth

Labial commissure of mouth
Fourteen Nylon sutures used to approximate the edges of this left cheek laceration, extending from the left commisure towards the left ear, allowing it to heal with considerably less scarring than it would without sutures.
Latin commissura labiorum oris
Code TA A05.1.01.012

The commisure is the corner of the mouth, where the vermillion border of the superior labium (upper lip) meets that of the inferior labium (lower lip).

The commisure is important in facial appearance, particularly during function such as smiling. As such it is of interest to dental surgeons.

Diseases that involve the commisure include angular chelitis.
