耳蜗电地形图(ECochG)已发展成为诊断/评估/监测梅尼埃病/内淋巴积水(MD/ELH)的重要工具。这份手稿提供了ECochG用于这些目的的最新情况。所提供的材料包括对耳蜗电的组成部分的描述；ECochG记录方法和参数；如何准备检查，包括受试者/患者的考虑；鼓膜记录电极的结构和放置；以及对耳蜗电的解释。还描述了旨在提高ECochG对MD/ELH的敏感性和特异性的各种方法。这些方法超越了现在常规的总和电位(SP)/动作电位(AP)幅度比的简单测量，包括SP对音调突发的幅度、SP/AP面积比以及AP对相反极性的短声的潜伏期差。
Electrocochleography (ECochG) has evolved as an important tool in the diagnosis/assessment/monitoring of Meniere's disease/endolymphatic hydrops (MD/ELH). This manuscript provides an update on the use of ECochG for these purposes. The material presented includes descriptions of the components of the electrocochleogram; ECochG recording approaches and parameters; how to prepare for an exam, including subject/patient considerations; construction and placement of a tympanic membrane recording electrode; and interpretation the electrocochleogram. Various approaches aimed at improving ECochG's sensitivity and specificity to MD/ELH also are described. These approaches go beyond simple measurement of the now-conventional summating potential (SP)/action potential (AP) magnitude ratio to include the SP magnitude to tonebursts, the SP/AP area ratio, and the AP latency difference to clicks of opposing polarity.
