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

Fistula of the 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 branchial pouch in an adult managed through an endoscopic approach. Endoscopic cauterization of 4th branchial pouch may be considered as an attractive alternative procedure for the management of this congenital anomaly.
