Congenital parotid gland fistula.

A rare case of congenital parotid gland fistula is reported. A 4-year-old boy presented with a fistula opening at the facial surface of the skin posterior to the left commissure of the lips. This fistula originated from an accessory parotid gland with a duct entirely distinct from the original Stensen's duct. Because of the salivary outflow from the fistula opening, the opening was translocated to the oral cavity using Delore's method.
