In an examination of the vestibular function of patients with unilateral deafness, simplified caloric tests were performed on 35 patients who had been followed in the ENT clinic of Tokyo Univ. Hospital. Among the three parameters employed, i. e., latency, duration and frequency, duration had the highest fidelity of vestibular response.<BR>The results of caloric tests were not significantly different between the deaf ear and the normal ear not only as to duration but also as to latency and frequency.<BR>In 13 of the 35 patients, the etiology of the deafness had been mumps, and in these patients, who had not experienced vertigo, there was no significant difference in the caloric response between the deaf and the normal ear. On the contrary almost all patients with delayed endolymphatic hydrops and vertigo had a depressed vestibular response in the deaf ear.<BR>It is concluded that the cochlea is more vulnerable to injury than the vestibule.
