Fistula of the fourth branchial pouch: report of a case treated by endoscopic cauterization

摘要

Fistula of fourth branchial pouch is a rare congenital cervical malformation. It typically affects child and occurs in the left side of the neck. Surgical removal of the entire fistulous tract through an external cervical approach is the treatment traditionally performed. We report a case of a right 4th bran- chial pouch in an adult managed through an endoscopic approach. Endoscopic cauterization of 4th branchial pouch may be considered as an attractice alternative procedure for the management of this congenital anomaly.
