“…Alternatively, the duct can be ligated proximal to the defect, as described in the study by Goldsworthy et al . (), causing atrophy of the gland (Harrison & Garrett ). This technique produces consistent atrophy of the parotid gland in contrast to the effects on mandibular and sublingual glands and this may be related to the predominance of serous cells in the acini of the parotid gland (DeYoung et al .…”

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.

“…Multiple surgical techniques have been described for the management of non-neoplastic inflammatory parotid disease (associated or not with lithiasis), such as parotidectomy (Trumpatori et al 2007, Guthrie & Hardie 2014, Proot et al 2016; opening of the duct for removal of the sialolith and primary closure or leaving it to heal by second intention (Tivers & Moore 2007); complete ligation of the duct (Harvey 1977, Goldsworthy et al 2013, Yoon et al 2017; resection of the affected part and anastomosis (Harvey 1977, Jeffreys et al 1996; primary repair of the affected duct in case of rupture (Harvey 1977, Jeffreys et al 1996 and marsupialization of the duct into the oral cavity (Ladlow & Gregory 2003).…”

There is an important morbidity associated with parotidectomy. The most commonly reported permanent complication is facial nerve injury. Methylene blue staining has been used as an intra-operative tool to improve tissue visualisation and preserve facial nerve integrity. objectIves: To describe the functionality and feasibility of the use of methylene blue for parotidectomy in dogs. MaterIals and Methods: Retrospective study included seven client-owned dogs that underwent parotidectomy after injection of methylene blue from 2016 to 2019 in a referral centre. Cross-sectional imaging was used to confirm parotid gland surgical disease and for staging purposes. All dogs underwent parotid resection and removal of the parotid duct after injection of methylene blue. Methylene blue was either administered via cannulation of the parotid duct or directly injected into the abnormal gland. results: In all cases, the gland stained dark blue within seconds without any evident leakage. Complete parotid gland resection and removal of the parotid duct was achieved successfully in all dogs with a mean surgical time of 97 minutes. Subjectively, the staining was useful to identify innervation outside the coloured gland and facilitated dissection. No complications, including facial nerve injury, were recorded. clInIcal sIgnIfIcance: Methylene blue staining for complete parotidectomy was feasible, rapid and easy in these dogs. It can be used as an indirect facial nerve identification technique, and can therefore facilitate dissection and possibly reduce the incidence of post-operative facial nerve paralysis.
