title: Surgical management of Stenson's duct injury by using double J stent urethral catheter.
abstract: BACKGROUND
  Parotid duct or gland injury can be caused by assault with a knife, bottle, electrical-saw, road traffic accident, or rarely gunshot and fractures of the facial skeleton. The injury can be in the form of laceration, ductal exposure, total cutting, or crushing of the duct. These conditions are difficult to diagnose because of complex anatomy and variable forms of the injury. A successful management of parotid duct injuries depends on early diagnosis and appropriate intervention; improper surgery may lead to complications such as sialocele or salivary fistula
  
  
  METHODS
  A 27-years-old man was presented to the maxillofacial unit, complaining of bleeding over the right side of his face after accidental exposure to a chain-saw three hours before admission. On examination, a 6cm deep lacerated wound was found over the right buccal area, suspecting facial nerve-buccal branch and parotid duct injury. Under general anesthesia the parotid duct injury diagnosed, microsurgical anastomosis of the cut-ends of the parotid duct performed using the double J catheter. Sutures and JJ stent removed seven and twenty postoperative days respectively. After a proper supportive treatment a complete healing of the duct was obtained with normal amount of saliva.
  
  
  CONCLUSIONS
  Herein, we described an easy yet efficient technique in management of parotid duct injury using a JJ stent which is often used for urethra. We think that use of JJ stent is a valuable technique to be used in the diagnosis and surgical repair of the parotid duct during traumatic facial and/or parotid injuries.
