First branchial cleft anomalies and the facial nerve.
First branchial cleft anomaly is an uncommon clinical problem that can be difficult to diagnose and treacherous to treat. It is generally believed that branchial anomalies arise from incomplete resolution of branchial cleft remnants. They may be a fistulous tract or cystic lesions, and they may be found in all age groups. This article presents three cases of first branchial cleft anomaly and offers an overview of the regional embryology and guidelines for surgical management and facial nerve preservation.
