A non-invasive technique for recording the cochlear action potential in adults without recourse to sedation or local anaesthesia is presented. This technique has been assessed in two ways: (1) A group of normal subjects was tested to obtain distributions of response amplitude and latency as functions of stimulus intensity. (2) A group of patients with Meniere's disease was tested with trans- and extra-tympanic electrocochleography to compare the intensity amplitude functions and wave-forms obtained from the two methods. On the basis of this study the use of extra-tympanic electrocochleography as a replacement for the trans-tympanic method is discussed.
本文介绍了一种无需镇静或局部麻醉即可记录成人耳蜗动作电位的非侵入性技术。该技术已通过两种方式进行评估：（1）对一组正常受试者进行测试，以获得作为刺激强度函数的反应幅度和潜伏期分布。（2）对一组梅尼埃病患者进行经鼓膜和鼓膜外电耳蜗图测试，以比较两种方法获得的强度幅度函数和波形。基于这项研究，讨论了使用鼓膜外电耳蜗图替代经鼓膜方法的问题。
