A parotid fistula and sialocele complicating temporomandibular joint surgery.

A case of a persistent parotid fistula and sialocele following temporomandibular joint surgery is described. This rarely reported complication is postulated to result from pre-existing bucco-masseteric obstruction of parotid outflow causing raised intraductal pressure in the patient. Following unsuccessful conservative management, the patient was cured by a 5-day course of restricted oral intake and propantheline bromide.
