摘　　要：突发性聋是指72小时内突然发生的病因不明,至少连续两个频率听力下降至少20 dBHL的感音神经性听觉丧失。我国虽缺乏大样本流行病学研究,但发病率有逐年上升的趋势,其预后也成为目前研究的热点和有待解决的问题。耳蜗电图在突发性聋的预后评估中有其重要价值,尤其在突发性聋的低频下降型和急性低频感音神经性聋中,可以判断其病因及转归并指导临床医师的进一步治疗方案。Sudden sensorineural hearing loss is defined as hearing loss of 20 dBHL in two contiguous pure-tone frequencies over 72 hours or less and its physiopathology remains unclear. Although there is no large sample epidemiological study in China, the incidence rate is increasing year by year. Its prognosis has become a hot topic and a problem to be solved. Electrocochleogram has important values in the prognosis evaluation of sudden sensorineural hearing loss, especially in low-frequency type of sudden sensorineural hearing loss and acute low-frequency hearing loss, which can diagnose the cause and outcome and guide clinicians to further treatment plans.
