脑干听觉诱发电位在脑瘫患儿听力障碍诊断中的应用

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

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。

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 opisthotie styloid process as signal electrode, ealvaria 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, 32 BAEP abnormal, 7 normal, positive rate 82%; 13 Peripheral hearing damages, 16 central hearing damages, 3 mingled damages. Conelusion：BAEP has significant clinical functions in detecting child＇s cerebral palsy hearing damage in an earlier stage. As a favorable technique for newborn baby hearing screening, infant hearing impairment and brainstem central hearing malfunctioning detection.
