近年来,由于电子计算机被应用于医学研究领域,已有可能不需经过手术,从人体引出耳蜗电位,即蜗电图。十多年来,经过多方面的研究,蜗电图(Electrocochleogram)客观测听方法已被应用于临床。 应用蜗电图法可记录出听神经动作电位,总和电位及耳蜗微音器效应。以此三种电现象为指标,不仅可以进行客观听力测定,研究内耳的机能,且可研究感觉神经性耳聋的发病机 In recent years, due to the fact that electronic computers are used in the field of medical research, it has been possible to derive the cochlear potential, ie, the volute map, from the human body without surgery. For more than a decade, after many researches, the objective measurement method of Electrocochleogram has been applied to clinic. The application of the Cephalogram method can record the auditory nerve action potential, the sum of potential and cochlear microphones effect. With these three electrical phenomena as an indicator, not only can objective hearing measurement, study the function of the inner ear, and can study the pathogenesis of sensory nerve deafness
