The etiology and true characteristics of vestibular neuronitis are still obscure, and some people do not use the name of vestibular neuronitis. We investigated the problems of our patients with vestibular neuronitis. The incidence of vestibular neuronitis was less than that of Meniere's disease or other vertiginous diseases. Usually, the etiology of vestibular neuronitis is considered to be common cold or upper respiratory inflammation. However, such episodes as common cold were very rare in our cases. The number of vertiginous attacks in vestibular neuronitis is said to be once, but in several of patients, few vestiginous attacks were seen.
As mentioned above, the etiology of vestibular neuronitis is not yet clear. Some regard vascular disorder as a cause, or consider it the same as the Guillaine-Barré syndrome. These should be investigated in the future.
