A congenital anomaly of the first branchial cleft is a rare defect. In 1959, Gore and Masson1 reported a case. They found 12 previous cases in a review of the literature. Stark,2 in 1959, reported a single case. The two patients presented in this report make a total of 16 recorded cases. The embryological formation of the branchial arches has been well described by Lyall and Stahl.3 Suffice it to say that the first branchial arch divides into two parts. The upper or maxillary portion forms the upper jaw and the lateral parts of the upper lip and cheek. The lower or mandibular portion forms the lower jaw, lower lip, and chin. Failure of fusion of the branchial cleft results in formation of a cyst or sinus tract.
