在医学领域中,近年来耳鼻喉科也出现了一些新的进展。首先是耳蜗电图,用此法测定听觉系统,将电极放于耳蜗或接近耳蜗处,以记录人的内耳的低伏电压并求得平均值。这对研究听觉系统的正常和病理功能,特别是对那些用其他方法不能检查或检查困难的幼儿是有实用意义的,更有助于辨别耳蜗和耳蜗后的损害,及确定耳蜗后病变的位置。至于电极安置的部位尚有许多争论,看来单电极还不能满足,在评价本法能否实用之前,技术上还必须配备多导电极。
In the medical field, there have also been some new advances in ENT in recent years. The first is the cochlear electrogram, using this method to determine the auditory system, placing the electrode at or near the cochlea to record the low voltage of the human inner ear and to obtain the average. This is useful for studying the normal and pathological functions of the auditory system, especially for young children who can not be inspected or checked by other methods, but also helps identify the damage after cochlear and cochlear implants and determine the location of post-cochlear lesions . There are still many controversies regarding the location of the electrodes. It seems that the single electrode can not meet the requirements. Before evaluating the feasibility of this Law, it must also be technically equipped with a multi-electrode.
