Peripheral vestibular syndrome in the dog: a review of 83 cases.

Clinical data and follow-up evaluations of 83 cases of peripheral vestibular syndrome in the dog were reviewed. The absence of physical abnormalities of the tympanic membrane and absence of radiographic changes within the tympanic bulla or petrous temporal bone were the criteria used to make the diagnosis of idiopathic benign vestibular disease. When grouped according to the cause of the syndrome, most of the dogs had been diagnosed as having either otitis media/interna (49%) or idiopathic benign vestibular disease (39%). Clinical evidence suggested that most of the cases of otitis media/interna were secondary to otitis externa.
