Abstract
This study assesses electrocochleographic (ECOG) potentials in a clinically defined Meniere’s group and compares the results with those from a normal control group. Electrocochleography was done in 42 cases of Meniere’s disease and was compared with 20 normal cases. All parameters of electrocochleography were studied with special emphasis on the summating potential/action potential (SP/AP) ratio. A SP/AP amplitude ratio of 0.49 was found in the Meniere’ group as compared to the SP/AP ratio of 0.03 in the control group. Latencies of SP and AP were also studied and compared between two groups.
