Abstract
Results of audiological analysis of Meniere's disease based on audiograms of patients with longterm follo-up, on the average 10 years, were reported.
The most characteristic feature was fluctuant hearing impairment with an average hearing changes of 25-30dB in lower frequencies.
Hearing impairment progressed in about 40% of the patients during observation period. The impairment progressed in high frequencies in cases with initially well-preserved hearing levels in high frequencies. In cases with high frequency loss, the impairment progressed in middle frequencies.
The audiogram of Meniere's disease, in general, show low tone deafness in the beginning, then low and high tone deafness, and lastly flat deafness. The progression is very slow and fluctuation persists for longer periods.
