目的研究脑干听觉诱发电位(BAEP)在语言学习困难儿童中的应用价值。方法应用丹麦Dantec厂家生产的Keypoin诱发电位监测仪,对我院2011年6月~2012年12月语言学习困难组及门诊正常对照组各35例儿童进行BAEP检查分析。结果正常对照组儿童BAEP检查测I、III、V波出现率为100%;语言学习困难儿童BAEP检查正常者为6例,异常29例,其中13例为双侧BAEP各波消失,7例为单侧BAEP各波消失,9例为各波潜伏期、波间期延长。结论 BAEP检查在语言学习困难儿童中阳性率高,可为患儿听力异常及神经传导径路异常提供客观诊断依据,便于患儿早期诊治。
Objective To study the value of brainstem auditory evoked potential (BAEP) in children with language learning difficulties. Methods The Keypoin evoked potential monitor manufactured by Dantec in Denmark was used to analyze BAEP in 35 children with learning disabilities and outpatients in our hospital from June 2011 to December 2012. Results The incidence of I, III and V wave in BAEP was 100% in normal control group. Six cases with normal BAEP in 29 children with language learning difficulties and 29 cases with abnormal BAEP disappeared in 13 cases Unilateral BAEP wave disappeared, 9 cases of the wave latency, wave interval prolongation. Conclusions The positive rate of BAEP in children with language learning difficulties is high, which can provide an objective basis for diagnosis of abnormal hearing and nerve conduction pathways in children with early diagnosis and treatment.
