Auditory evoked brainstem responses (ABR) is a non-invasive electrical potential registration which evaluates the auditory tract from the middle ear to the auditory cortex in the first 12 milliseconds (ms). The ABR is an important otoneurological evaluation.
Confirm the test's usefulness, major incidence and topography according to are range gender considering the absolute latencies of the waves and interpeak intervals.
We retrospectively analyzed 403 tests from a private clinic in the city of Jundiaí-São Paulo State-Brazil, from patients suspected of auditory damage or central nervous disorder, and the patients were broken down according to gender and age.
ABR is an important test to determinate the soundness of the auditory tract, the electrophysiological thresholds and topodiagnosis. We found no differences between type of loss and gender; there was a major incidence of retrocochlear findings among male patients between 12-20 years old; children under one year with risk factors did not present higher incidences of auditory findings when compared with all the population analyzed. The absolute latencies of waves I, III and V were higher in males, but the interpeak intervals were similar in both genders, showing that interval I-III was more frequently altered.
听觉诱发电位脑干反应（ABR）是一种非侵入性的电位记录方法，可在最初12毫秒（ms）内评估从中耳到听觉皮层的听觉通路。ABR是一项重要的耳神经学评估。
根据年龄范围和性别，考虑波的绝对潜伏期和峰间期，确定该测试的有用性、主要发病率和定位情况。
我们回顾性分析了巴西圣保罗州容迪亚伊市一家私人诊所对403名疑似听觉损伤或中枢神经紊乱患者进行的测试，并根据性别和年龄对患者进行了分类。
ABR是确定听觉通路完整性、电生理阈值和定位诊断的一项重要测试。我们发现听力损失类型与性别之间没有差异；12至20岁男性患者中蜗后病变的发病率较高；与所有分析人群相比，有危险因素的1岁以下儿童未表现出更高的听觉病变发病率。男性的波I、III和V的绝对潜伏期较长，但两性的峰间期相似，表明I-III间期更常发生改变。
