A Case of Congenital Lateral Fistula of the Upper Lip and Nasal Associated with Unilateral Cleft Lip

Abstract

Congenital lip fistulas usually occur in the lower lip or in the angle of the mouth, but upper lip fistulas are extremely rare. We report a rare case of congenital lateral fistula of the upper lip and nose associated with a right side cleft lip. In this case, dimples in the right upper lip vermilion and ala were observed. At 6 months of age, a fistulectomy was performed with rhinocheiloplasty under general anesthesia. Histological examination showed that the fistula was lined by squamous epithelium. The postoperative course has been uneventful after a 3-year follow-up.
