Abstract
We investigated severe cases of Meniere's disease. The diagnosis was based on the criteria of diagnosis of severe cases of Meniere's disease by Watanabe (1978), Severe cases existed in 11 (7 males and 4 females) of 41 patients with Meniere's disease. In 10 of these cases, attacks of vertigo occured above once a month on an average for more than 3 months. In addition, their hearing level was more than 40 dB and they had 20% canal paresis. However, there was no significant difference in the results of electro-cochleography and glycerol test between patients with and without severe cases.
