自听觉脑干反应技术应用于神经耳科学诊断以来,由于它在诊断听神经瘤中的高度敏感性(95％～100％),使得听神经瘤诊断的听力学过筛试验取得了突破性的进展。虽然发生在小脑桥脑角处其它肿物而听觉脑干反应正常的并不少见,但是发生在第八颅神经而听觉脑干反应正常还是很少见的。本文回顾了Michigen大学1980年1月以来收治的120例听神经瘤患者,分析了听觉脑干反应各项参数,其中二例听觉脑干反应完全正常,结果如下:病例1,女性,38岁,因左耳进行性感音神经性聋
Since auditory brainstem response has been used in the diagnosis of neurological otology, breakthroughs have been made in the audiological screening tests of acoustic neuroma due to its high sensitivity in the diagnosis of acoustic neuromas (95% -100%). Although it is not uncommon for other tumors to have normal auditory brainstem response at the cerebellopontine angle, the auditory brainstem response to the eighth cranial nerve is normal or rare. In this review, we reviewed 120 patients with acoustic neuroma admitted to Michigen University since January 1980 and analyzed various parameters of the auditory brainstem response. Two of the patients had normal auditory brainstem response. The results were as follows: Case 1, female, 38 years old, The left ear for a sexy acoustic deafness
