Abstract:
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 new orifice throughout a 3-year follow-up period. We also performed a review of the current relevant data.
