Abstract
One hundred fifteen cases with Meniere's disease and sudden deafness were reviewed.
The results were as follows.
1) Average hearing loss of patients with sudden deafness (59.2 dB) was significantly poorer than the loss of cases with Meniere's disease (36.9 dB).
2) Patients with Meniere's disease and atypical Meniere's disease showed more frequently C. P. or D. P. in the caloric test than those with sudden deafness.
3) Cases with Meniere's disease more frequently noticed vertiginous attack after discharge than those with atypical Meniere's disease.
4) There were no marked differences of the results in the caloric test between patients with Meniere's disease within 2 years and patients over 2 years.
We might conclude that the prognosis of Meniere's disease could not be suspected from the results of caloric test and pure tone audiometry.
