Transtympanic Electrocochleography in Meniere's Disease

Abstract

Transtympanic electrocochleography was performed in 51 patients with Meniere's disease. Both ears, (i. e., the ear affected by Meniere's disease and the contralateral ear) were examined. The SP-AP ratio of the ear with Meniere's disease (mean 0.40) was significantly higher than that of the contralateral ear (mean 0.27) (p<0.01). However, in six patients (14%) the SP-AP ratio of the contralateral ear was over 0.40. Therefore, the ear contralateral to the ear affected by Meniere's disease should not be classified as normal.
