Surgical excision of a congenital lateral fistula of the upper lip. An intra-oral approach.

A new technique for removal of a congenital lateral upper lip fistula is described, using an intra-oral approach. Previous reports of removal of such a congenital malformation have used an extra-oral approach. The technique described allows for excellent visualization of the fistula without cutaneous lip incision. Using this approach, good aesthetic results and complete removal of the fistula and associated mucous glands can be obtained.
