A case of congenital lateral fistula of the upper lip at the cleft vermilion in a boy with cleft lip

Abstract

We report a rare case of a congenital lateral fistula of the upper lip at the vermilion in a 2-month-old boy with cleft lip. Under general anesthesia, fistulectomy was carried out with cheiloplasty bythe modified Millard technique. The fistulous tract terminated in the cartilaginous membrane of the nasalseptum. Histological examination revealed that the fistula was lined by stratified squamous epithelium, similar to the epithelium of the lip vermilion.
