脑干听觉诱发电位对儿童语言发育障碍病因诊断的价值

Values of brainstem auditory evoked potential in the etiological diagnosis among children with language development disorder

目的:探讨脑干听觉诱发电位(Brainstemauditoryevokedpotential,BAEP)检查在学龄前儿童言语障碍病因诊断的应用价值。方法:应用肌电/诱发电位仪描记52例言语障碍学龄前儿童的BAEP并与影像学资料(CT或MRI)比较。结果:52例学龄前言语障碍儿童中BAEP异常38例(占73.08%),波Ⅰ、Ⅲ、Ⅴ的出波耳数分别为89例(85.58%),82例(78.85%)、84例(80.77%),而对照组30例波Ⅰ、Ⅲ、Ⅴ的出波耳数均为60只,出波率为100%,两组比较差异有显著性(u值分别为4.56,3.59,3.38,P值均<0.01)。影像学检查异常19/46例(41.30%),BAEP阳性率较影像学检查阳性率高(χ2=8.86,P<0.05)。结论:BAEP检查在有言语障碍的学龄前儿童中阳性率高,与影像学检查在言语障碍的病因诊断有一定的互补性,对指导康复治疗具有重要的意义。BAEP检测可作为言语障碍学龄前儿童的常规检查项目。

AIM:To explore the values of brainstem auditory evoked potential(BAEP) in the etiological diagnosis among preschool children with language development disorder. METHODS:An evaluation of BAEP was carried out in 52 preschool children with language development disorder and 45 of them were examined by iconography(CT or MRI). RESULT:There were 38 (73.08%)cases showed abnormally in BAEP,the common abnormities were showed as the incidence rates of the main waves(Ⅰ?Ⅲ?Ⅴ)were declined , the incidence rate of waveⅠ?Ⅲand Ⅴwere 89(85.58%), 82(78.85%) and 84 (80.77%) cases.But there was 60(100%)cases of each incidence rate of waveⅠ?Ⅲand Ⅴin the normal control group.They were significant difference between the two groups(u=4.56,3.59,3.38 respectively,P< 0.01).There were 19(41.30%)cases showed abnormity in iconography,it was lower than those in BAEP (χ2=8.86,P< 0.05).
