Plain-English summary
A group of 14 dogs had a soft, non-painful swelling on the side of their faces caused by a condition called parotid sialocoele, which is related to the salivary glands. To treat this, the dogs underwent a surgery called parotidectomy, which involves removing the affected gland. While some dogs experienced complications like temporary facial nerve paralysis and other surgical issues, none had a recurrence of the sialocoele after an average follow-up of 14 months. Overall, the surgery was successful in resolving the problem for these dogs.

Abstract
OBJECTIVES: To describe the presentation, diagnosis, cause, complications and outcome in 14 dogs that presented with a parotid sialocoele and that were treated by complete parotidectomy. MATERIAL AND METHODS: Multi-institutional retrospective study. RESULTS: Each dog presented with a non-painful, fluctuant, soft tissue mass over the lateral aspect of the face in the region of the parotid salivary gland. Diagnosis was made by sialoradiography (3/14), CT (3/14), ultrasound (11/14) and MRI (2/14). The cause of the sialocoele could be determined in 8 of 14 patients and included: foreign body (2/14), sialolithiasis (1/14), neoplasia (3/14), salivary gland lipomatosis (1/14) and trauma (1/14). Treatment incurred one anaesthetic complication (regurgitation) and seven postoperative surgical complications [self-limiting seroma formation (2/14), haemorrhage (1/14), wound dehiscence (1/14), abscessation 7 months postoperatively (1/14) and facial nerve paralysis (2/14)]. Sialocoele did not recur in any dog during a median follow-up time of 14 months. CLINICAL SIGNIFICANCE: Parotidectomy has been considered a technically challenging procedure but can have a good success rate with long-term resolution of the clinical symptoms. Intra- and postoperative complications are reasonably common.
