脑干听觉诱发电位在脑瘫患儿听力障碍诊断中的应用

目的：探讨脑干诱发电位（BAEP）在脑瘫患儿听力障碍诊断中的临床应用。方法：收集39例脑瘫患儿,应用amplaid MK 12型脑干诱发电位仪测试,在双耳垂或耳后茎突为信号电极,颅顶区为参考电极,前额或手腕为地电极。用1000Hz短声单耳膨胀刺激的BAEP资料进行分析。结果：39例脑瘫患儿,BAEP异常为32例,正常7例,阳性率82%,其中周围性听路损害13例,中枢性听路损害16例,混合性损害3例。结论：BAEP检查对早期发现小儿脑瘫听路损害有重要临床价值,是早期筛查新生儿、婴幼儿听力障碍及判断脑干中枢性听功能异常的优良技术。

The Application of Brainstem Auditory Evoked Potentials (BAEP)in the Hearing Impairment Diagnosis of Cerebral Palsy Children

Objective: to explore the clinical application of BAEP in the hearing impairment diagnosis of cerebral palsy children. Methods: gathering 39 cerebral palsy children found in our hearing inspection section from June 2004 to May 2007; using amplaid MK12 BAEP, earlobes or opisthotic styloid process as signal electrode, calvaria as reference electrode, forehead or wrist as earth electrode; analyzing BAEP statistics stimulated by 1000 Hz short wave monaural expansion. Results: among 39 cerebral palsy children, 3...
