We studied the initial symptoms, dizziness and prognosis in the patients with low tone sensorineural hearing loss in our department between 1988 and 1992. The subjects were 41 cases, 18 males and 23 females, and the average age was 40.1.
There were 27 monoattack type (66%) and 14 recurrent type (34%). In 27 cases examined within one month after onset, the rate of recovery or improvement was very high [26/27 (96%)].
There were 7 cases which accompanied dizziness, including 4 monoattack recovery type, 1 recurrent recovery type, 1 recurrent improved type, and 1 recurrent progressive type, which shifted to Meniere's disease. This indicated no connection between dizziness and the prognosis of hearing loss.
There were some patients, who had shown a canal paresis in caloric test in the early stage, became normal response as their hearing was improved. It suggested that the disease might have accompanied with a transient vestibular disorder.
