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.
本研究评估了临床确诊的梅尼埃病组的耳蜗电图（ECOG）电位，并将结果与正常对照组进行比较。对42例梅尼埃病患者进行了耳蜗电图检查，并与20例正常病例进行比较。研究了耳蜗电图的所有参数，特别强调了总和电位/动作电位（SP/AP）比值。梅尼埃病组的SP/AP幅度比值为0.49，而对照组的SP/AP比值为0.03。还研究并比较了两组之间SP和AP的潜伏期。
