Abstract
This report describes the clinical features of a series of dogs with pharyngeal salivary mucoceles. A retrospective study of 14 dogs with pharyngeal mucocele was performed. Medical records from 1983 to 2003 were reviewed for information regarding signalment, clinical signs, diagnosis, surgical procedures, and short-term and long-term outcome. Miniature and toy poodles were common breeds in the study population, and 79% of the dogs were male. The most common presenting sign was dyspnea (50%). Diagnosis was by fine-needle aspirate, which revealed a mucoid substance in 93% of dogs. Histopathology of the excised salivary glands revealed lymphoplasmacytic inflammation in all dogs that had histopathology performed. Forty-three percent of the dogs had a cervical mucocele on the same side as the pharyngeal mucocele. Surgical therapy was performed in 13 dogs, which consisted of excision of the mandibular and sublingual salivary glands, excision of the mucocele, or marsupulization of the mucocele. Only two dogs had recurrence of the pharyngeal mucocele. In this study, pharyngeal mucoceles occurred in predominantly small dogs that frequently presented with respiratory signs. Surgical treatment was successful in most dogs.
