== Description ==
*Traumatic wound
A salivary fistula can result from injury to any salivary gland, but most commonly the parotid. Fistulas forming from other glands is uncommon.
Injury may be due to:
*Traumatic wound to the face e.g. bite wound
*Abscess drainage
*Abscess drainage
*Iatrogenic rupture
*Iatrogenic rupture following prior surgery in the region
The continuous flow of saliva prevents healing.
*Exopthalmus is the most likely cause of zygomatic duct injury
==Diagnosis==
===Clinical Signs===
The continuous flow of saliva prevents healing and therefore a fistula develops
*Discharge from fistula (must be differentiated from a draining sinus)
==Treatment==
When a salivary duct injury occurs due to trauma on the face, this results in a fistula being created which will cause discharge of saliva onto the face. Discharge from the gland may be noticably worse before or during feeding.<br>
Surgical ligation of the duct or complete removal of the gland.

*Fistula visible over parotid region, or located upon clinical examination
*Discharge from fistula (must be differentiated from a draining sinus) resulting in a visibly wet face
*History or current presence of a wound over the parotid region<br>
Differentiation from a draining sinus by assessment of the discharge- salivary fistula will discharge a golden or blood tinged saliva, which will be viscous and 'stringy' in appearance. Mucous can be identified in this by use of periodic acid-schiff stain.
== Treatment ==
Surgical ligation of the duct or complete removal of the gland is neccesary
