Abstract

ObjectivesTo describe the clinical presentation, diagnostic findings, surgical treatment and outcome of dogs diagnosed with parotid duct ectasia.Materials and MethodsMedical records of dogs diagnosed with parotid duct ectasia between 2010 and 2023 at six small animal referral hospitals were retrospectively reviewed. Outcome was assessed by contacting the owners or referring veterinarians.ResultsFourteen dogs were included. Lateral facial swelling was the most common clinical presentation. CT revealed a tortuous cavitary tubular fluid-filled structure consistent with a dilated parotid duct in all dogs. Surgical treatment included marsupialisation of the parotid duct papilla, surgical exploration of the duct alone, parotid duct marsupialisation with surgical exploration of the duct, parotidectomy or en-bloc parotid duct resection. The aetiology of parotid duct ectasia was not established in 13 of 14 dogs. In one case, a foreign body was retrieved from the duct. No recurrence of clinical signs was noted during the follow-up period (range 21 to 2900 days).Clinical SignificanceParotid duct ectasia should be considered for dogs with a lateralised fluctuant non-painful tubular facial swelling. Surgical management was associated with a favourable prognosis without evidence of recurrence in all cases reported in the case series.
