There have been many publications about enlarged summation potentials with Meniere patients. The phenomenon was interpreted as being due to endolymphatic hydrops. 50 patients were examined electrocochleographically who were suffering from the symptoms low-frequency hearing loss, vertigo, tinnitus and pressure in the ear. As in other previous studies a significantly enlarged negative summating potential was found in 70% of the patients. With 10 patients electrocochleography was performed before and three hours after glycerol ingestion. In 8 patients the SP became smaller, although the subjective hearing threshold improved in only 4 cases. The study shows that enlarged SP is a common finding in Meniere patients; it underlines the diagnostic value of electrocochleography in this disease.
关于梅尼埃病患者总和电位增大已有许多相关文献发表。该现象被解释为是由内淋巴积水所致。对50例患有低频听力损失、眩晕、耳鸣和耳部压迫感症状的患者进行了耳蜗电图检查。和之前其他研究一样，在70%的患者中发现了明显增大的负性总和电位。对10例患者在摄入甘油前及摄入后三小时进行了耳蜗电图检查。在8例患者中，总和电位变小，尽管只有4例患者的主观听力阈值有所改善。该研究表明，总和电位增大在梅尼埃病患者中是常见表现；它强调了耳蜗电图在该疾病中的诊断价值。
