Bilateral first and second branchial cleft fistulas: a case report.

Branchial cleft anomalies-which include branchial cysts, sinuses, and fistulas-are uncommon developmental defects of the neck. Approximately 2 to 3% of cases are bilateral; bilateral presentations appear to have a familial component. Only 5 cases of bilateral branchial cleft fistulas have been reported in the English-language literature, and only 1 case of simultaneous first and second branchial cleft fistulas has been previously reported. We report what to the best of our knowledge is the second case of bilateral first and second branchial cleft fistulas.
