79例语言障碍儿童脑干听觉诱发电位的结果分析

摘要

目的 研究脑干听觉诱发电位(BAEP)在语言障碍儿童中的变化规律及应用价值.方法 采用丹麦维迪KEY-POINT诱发电位仪,对我院2006年8月～2008年12月间79例语言障碍儿童进行BAEP检测结果 分析.结果 患儿BAEP总异常率为64.6%,其中15.7%为双侧BAEP各波消失;11.8%为单侧BAEP各波消失,伴另侧BAEP各波异常;72.5%为各波潜伏期(PL)、波间期(IPL)异常.结论 BAEP是一种简便、无创性、阈值稳定、结果 可靠、重复性强的检查方法 ,对于语言障碍儿童听力损害及神经传导通路的异常可为临床提供有价值的客观指标.%Objective To study the change and its application of the brain stem auditory evoked potentials (BAEP) in language -impaired children. Methods We used evoked potentials Denmark Wedy Keypoint device to analysis the BAEP test results of the 79 cases of children in our hospital from August 2006 to December 2008. Rsults The total rate of BAEP abnormalities in children was 64.6% , of which 15.7% for one of the bilateral BAEP wave disappeared, 11.8% for the unilateral BAEP wave disappeared with the other side of the wave being abnormal BAEP,and 72.5% for the wave latency (PL) and wave interphase (IPL) abnomal. Conclusion BAEP is a sim-ple, noninvasive, threshold stability, results reliable and reproducible method of examination. For language -impaired children of hearing damage and abnormal neural pathway ,it can provide valuable objective indicators.
