The advantages and disadvantages of the transtympanic and extratympanic methods for recording electrocochleographic potentials (ECochG) are discussed. Our extra-tympanic method (adapted from Coats) and some results are presented. We conclude that for broad clinical application an ear canal surface electrode is the method of choice for recording ECochG, unless the primary question is one of threshold measurement. If the registration of brainstem potentials from the vertex does not show a potential I, we recommend simultaneous recording of ECochG by an extratympanic method with earphones.
讨论了经鼓膜和鼓膜外方法记录耳蜗电图（ECochG）的优缺点。介绍了我们的鼓膜外方法（改编自Coats）及一些结果。我们得出结论，对于广泛的临床应用，除非主要问题是阈值测量，否则耳道表面电极是记录ECochG的首选方法。如果从头顶记录的脑干电位未显示出I波，我们建议用带耳机的鼓膜外方法同时记录ECochG。
