听觉脑干反应(AUR)对神经耳科学的诊断是一种非常敏感和有价值的方法,对蜗后病变,尤其是对听神经瘤的诊断是一个突破。然而试验耳的声学特性对短声(click)诱发ABR可能出现含糊的解释,尤其在高频听力减退的时候。因为耳蜗性和蜗后性病变的病人听力减退多在2000～4000Hz范围,而短声刺激使兴奋占优势的也在基底膜这一区域。因此,当听力减退严重时,短声诱发ABR可能没有反应,或者Ⅰ波消失,仅有两耳Ⅴ波潜伏期的比较,在这些病例Ⅴ波潜伏期的改变是由于耳蜗性听力丧 Auditory brainstem response (AUR) is a very sensitive and valuable method for the diagnosis of neurological otology. It is a breakthrough in the diagnosis of postcochlear lesions, especially acoustic neuromas. However, the acoustic properties of the test ear may vaguely explain the click-induced ABR, especially at high-frequency hearing loss. Because cochlear and retroperitoneal lesions in patients with hearing loss more in the 2000 ~ 4000Hz range, and short-term stimulation of the excitement is also dominant in the basement membrane in this area. Therefore, when severe hearing loss, short-tone induced ABR may not respond, or I wave disappeared, only the two Ⅴ wave latency compared to Ⅴ wave latency in these cases the change is due to cochlear hearing loss
