Parotid duct injuries.

Treatment of parotid duct injuries varies with the anatomic location and the type of injury involved. The duct may be injured by sharp or blunt facial trauma. Moderate to severe facial swelling or clear drainage shortly after injury in the region of the parotid gland or its duct should alert the clinician to this potential problem. The anatomic considerations, as well as a variety of techniques to treat these injuries, are presented. A case involving a particularly resistant chronic ductal injury, with an extraoral fistula and its eventual cure, is presented. A second case of a lacerated duct which was diagnosed and treated primarily is presented as a contrast.
