Mandibular Sialoadenectomy in Dog with Sialocele: Case Report

The report aims to describe a case of left mandibular sialocele in a dog. A male, castrated, Shih Tzu dog, weighing 7 kilograms and five years old, was treated at the Veterinary Hospital of the School of Veterinary and Zootechnics at the Federal University of Goiás. A fluctuating non-painful subcutaneous swelling was observed in the left ventral cervical region during the clinical examination. Image tests revealed anechoic content with dilation of the salivary duct, heterogeneity and enlargement of the left mandibular gland and possibility of sialolithiasis. Besides, cytological analysis showed results that confirm the diagnose of left mandibular sialocele. Following the diagnosis, surgical treatment was made, performing sialoadenectomy. A skin incision was made ventral to the ear canal in the dorsal direction caudal to the angle of the mandible, and the patient was evaluated for days. Salivary sialocele is the most common sialoadenopathy in dogs and its diagnoses require several image methods and the surgical treatment is essential for healing and improving clinical signs.
