Ectopic Parotid Main Duct on Buccal Mucosa: A Case Report and Literature Review

Ectopic parotid main duct (Stensen's duct) orifice is a rare anatomic abnormality of the salivary gland. We report a case in which the patient's left Stensen's duct opened on the left buccal skin. After surgery to perform parotid duct transposition, the buccal fistula was closed, and the saliva secreted by the parotid gland could overflow smoothly through the neworifice throughout a 3-year follow-up period. We also performed a review of the current relevant data. (C) 2020 American Association of Oral and Maxillofacial Surgeons.
