【摘要】：目的探讨高刺激率听性脑干诱发电位(ABR)在诊断儿童良性阵发性眩晕(Benign ParoxysmalVertigo of children,BPV)的临床价值。方法根据BPV诊断标准,选取BPV的儿童60例和非BPV对照组20例。BPV组根据眩晕病程进展分为2周内眩晕发作组和无眩晕发作组。所有入组病例行听力学检查,对纯音测听听阈阈值、声导抗、高刺激率ABR进行比较,分析BPV及对照组之间听力学特征差异。结果(1)BPV组60例患儿及对照组20例儿童纯音测听、声导抗检查结果全部正常,听力无显著性差异。(2)BPV组中高刺激率ABR异常率为41.7%(25/60),正常对照组高刺激率ABR异常率为0%(0/20),两者有统计学差异,P0.01。BPV组中:2周内眩晕发作组和无眩晕发作组,分别进行高刺激率ABR检查:2周内眩晕发作组高刺激率ABR异常率为63.6%(21/33),而2周内无眩晕发作者高刺激率ABR异常率为14.8%(4/27),两者有统计学差异,P0.01。结论高刺激率ABR与儿童BPV、尤其是发作期的BPV具有一定的相关性。
[Abstract]:Objective to investigate the clinical value of auditory brainstem evoked potentials (ABR) with high stimulation rate in the diagnosis of benign paroxysmal Vertigo of childrenn BPVs in children. Methods according to the diagnostic criteria of BPV, 60 cases of children with BPV and 20 cases of non-BPV control group were divided into two groups according to the course of vertigo. The auditory threshold, acoustic conductance and ABR of pure tone audiometry were compared, and the differences of auditory characteristics between BPV and control group were analyzed. Results the results of pure tone audiometry were normal in 60 children in BPV group and 20 children in control group. There was no significant difference in hearing. The abnomal rate of ABR in the BPV group was 41.7% and that in the normal control group was 0% / 20%. There was a significant difference between the two groups (P 0.01. 01.) in the two groups, the abnormal rate of ABR was 41.7% and 25 / 60%, respectively. There was a significant difference between the two groups. The ABR abnormal rate of high stimulation rate was 63.621 / 33 in the vertigo attack group within 2 weeks, while the ABR abnormal rate was 14.84 / 27 in the patients without vertigo attack within 2 weeks. There was a significant difference between the two groups (P0.01). Conclusion there is a certain correlation between high stimulation rate ABR and BPVs, especially BPV in children.
