Vestibular neuronitis is manifested by severe rotating vertigo without any cochlear sign. The underlying pathologic findings such as its etiology and site of lesion remain elusive still. Twenty one cases of vestibular neuronitis were studied about its clinical character neurootologically for confirmation of its pathologic findings. The results were as follows. Among peripheral vertiginous disorders, the vestibular neuronitis showed less occurrence than Meniere's disease and BPPV. The preceding upper respiratory infection was showed by the greater part of total cases but was not showed by a few cases. The subjective symptom and spontaneous nystagmus were reduced and then disappeared within three weeks in the half of cases. But there were also many cases which continued to show these symptoms for longer period. The poor prognosis and other complication was absent in all cases. The vertigo attack was one time most cases but was two or three times in some cases. In case of no response in initial caloric test, no response was continued for a long time. The case of reduced response tended to recover as time passes.
