Abstract
Abnormal brainstem auditory-evoked responses (BAER) were recorded in five dogs with suspected middle/inner ear diseases. BAER abnormalities were consistent with conductive, cochlear sensorineural, or retrocochlear sensorineural hearing impairment, and these results enabled us to reveal otitis media, interna, or brainstem disease, respectively. Since BAER can be obtained from a dog with no or only mild sedation, this test was useful, especially in a situation where general anesthesia is undesirable or repeated examinations are needed. Our results indicated that BAER is of great value in helping to arrive at a diagnosis or in conducting a follow-up evaluation of middle/inner ear diseases in dogs where the lesion localization was in the auditory pathway.
