Successful replantation of a portion of the upper and lower lip with the oral commissure.

The orofacial region consists of numerous structures that interact in an intricate and dynamic fashion with the oral commissure playing a central role in facial function, expression, and cosmesis. Traumatic amputations of this complex are rare. This case illustrates the successful replantation of portions of the right upper and lower lip with the oral commissure in a 6-year-old girl after traumatic amputation by a dog bite.
