A salivary fistula can result from injury to any salivary gland, but most commonly the [[Parotid Gland - Anatomy & Physiology|parotid]]. Fistulas forming from other glands is uncommon. Damage may be due to traumatic wound to the face e.g. bite wound or abscess drainage. Exopthalmus is the most likely cause of zygomatic fistula. The continuous flow of saliva due to trauma to the face prevents healing and therefore a fistula develops. Discharge from the gland may be noticeably worse before or during feeding. | A salivary fistula can result from injury to any salivary gland, but most commonly the [[Parotid Gland - Anatomy & Physiology|parotid]].
