Clinical Observation for Primary Repair of the Severed Parotid Duct

Abstract

The incidence of facial injuries is high compared to injuries in other areas because the face is in an exposed position without protective covering. This facial injuries are simple or crush injuries involving soft and hard tissues, facial nerves or parotid duct etc. Therefore, in the clinical management of facial injuries, it is the responsibility of the physician to restore appearance and function to the best of his ability in order to return the patient to an active productive life as soon as possible with minimal cosmetic or functional disability.
The parotid duct or Stensen´s duct is located at the intersection of a hori￢zontal line extending from the tragus of the ear to the mid-portion of the upper lip. As the duct crosses the outer portion of the masseter -muscle( the middle third of the line), it lies close to the zygomatic. and buccal branches of the facial nerve. It is at this point that the duct is most-superficial and susceptible to injury. The severed parotid duct should be repaired at the time of the wound closure. If the repair of the severed parotid duct is failed, the
patient has great distress from combination of facial deformity and corpious outpouring of saliva. Since Dieulafe implanted parotid duct or fistulous cloaca into the buccal mucossa by creating a mucosal flap in 1919, many ingenious methods for primary repair of the severed parotid duct had been developed. Author performed end to end anastomosis using a 23-gauge polyethylene catheter as a dowel over which to suture the duct in nine patients. The success of the, anastomosis could be judged by sialograms taken postoperatively showing the duct system to be patent, and author present with as review of literature.
