Surgical management of parotid salivary duct rupture secondary to non-iatrogenic trauma in a dog

A 3-year-old French bulldog presented for evaluation of recurrent swelling and a fistula on the right cheek after a dog fight. A large volume of serous fluids was identified on the wound immediately after atropine drops. A diagnosis of parotid salivary duct rupture secondary to trauma was made. On surgical exploration, the thickened proximal segment of the severed duct was identified and circumferentially double ligated with 3-0 silk. No evidence of swelling and normal appearance of the parotid salivary gland were identified 4 months postoperative recheck. No further problems were noted 10 months postoperatively phone-call. To the author's knowledge, this is the first reported case of successful proximal parotid duct ligation of parotid salivary duct rupture secondary to non-iatrogenic trauma.
