A Case of First Branchial Cleft Anomaly

Abstract

We report a case of first branchial cleft anomaly. A 16-year-old girl consulted our hospital, complaining of swelling at the angle of the mandible.
MRI imaging revealed the tract of the fistula. The tract extended from the angle of the mandible, through the parotid gland, to the intertragic notch.
We excised the fistula, utilizing superficial lobectomy to preserve the facial nerve. Facial palsy was not observed after surgery.
Microscopic examination of the fistula showed squamous epithelium and skin adnexa, and this lesion was diagnosed as first branchial cleft anomaly.
