Anatomical terminology

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.
