The efficacy of treatment in vertigous attacks and hearing loss in Meniere's disease has been evaluated according to AAO-HNS (1985) criteria.
However, the Committee of the Japan Society for Equilibrium Research proposed preliminary guidelines for reporting treatment results in Meniere's disease in 1994.
In the present report, we compared the guidelines of the Committee of the Japan Society for Equilibrium Research with that of modified AAO-HNS (1985).
The results of evaluation 12 months after the initiation of treatment were similar to those after 24 months. The former evaluation was superior to the latter because there were fewer dropouts. Hearing levels were assessed from the three frequency pure-tone average (PTA) at 500 Hz, 1 kHz, 2 kHz. If pre and post treatment hearing levels were evaluated using the poorest hearing level in the follow-up periods, there was no significant difference between treatment results evaluated using the guidelines of the Committee of the Japan Society for Equilibrium Research (PTA: 250 Hz, 500 Hz, 1 kHz, 2 kHz) and those using the modified AAO-HNS guidelines (PTA: 500 Hz, 1 kHz, 2 kHz).
Because there are some cases with contradictory results between vertigous attacks and hearing level, new methods should be determined for evaluating overall treatment results in Meniere's disease.
