The vermilion myomucosal flap for the treatment of oral commissure gunshot wound deformities.

The vermilion myomucosal advancement flap was successfully used to reconstruct the oral commissure for a wide range of deformities in three patients with facial gunshot wounds. In one case, a delayed cross lip flap was later used to restore the philtrum of the upper lip, despite the fact that the cutaneous perforating vessels of the cross lip flap had previously been divided.
