Abstract

In the head and neck area, a congenital fistula of the cheek is rare, while cervical and aural fistulae are often seen. We report a case of congenital accessory parotid gland duct fistula on the cheek successfully treated by drainage in the oral cavity. A 1-year-old boy presented with a fistula opening at the facial surface of the left cheek. The fistula was located at the center of the left cheek, 15 mm posterior to the left commissure of the lips, and discharged saliva-like exudate (which increased during meals). Three accessory ears of 3 mm in diameter were also found in front of the left ear. The pyelography of the left parotid duct revealed normal left parotid gland and duct within the normal position. Fistelography revealed that the glandular tissue existed at 5 mm from the opening. The fistula had no attachment with the normal parotid gland and duct. These findings led us to make a diagnosis of congenital accessory parotid gland duct fistula on the cheek. Surgical drainage of the fistula in the oral cavity was performed. The fistula translocated to the oral cavity was open with salivary flow one year after the operation.
