摘要
目的探讨诱发电位不同刺激强度对大前庭导水管综合征患者短潜伏期负反应引出率的效果对比。方法选取60例(112耳)大前庭导水管综合征患者作为研究对象,研究时间为2017年1月至2018年9月,均实施四种声刺激模式下的听性脑干反应,即为气导clickABR、骨导clickABR、Tb-500HzABR、Tb-1000HzABR,且对不同刺激声条件下短潜伏期负反应及短潜伏期负反应引出率进行观察及评估。结果于60例(112耳)患者中可发现引起短潜伏期负反应共60耳、百分比为53.57%;且在60例患者中可发现轻度听力损失共4例,均引出短潜伏期负反应;中度听力损失共20例,引出短潜伏期负反应为12例;重度听力损失共30例,引出短潜伏期负反应为16例;极重度听力损失共6例,引出短潜伏期负反应为2例。60例(112耳)患者经气导clickABR刺激后引出率为48.21%,经Tb-500HzABR刺激后引出率为26.79%,经骨导clickABR刺激后引出率为5.36%,经Tb-1000HzABR刺激后引出率为28.57%;以上四种结果对比存在明显异常,P<0.05。结论气导click ABR声刺激模式所引起的短潜伏期负反应引出率更高,可为临床早期诊断提供有效参考依据。
Objective To investigate the effect of different evoked potentials on the short-latency negative response rate in patients with large vestibular aqueduct syndrome. Methods 60 patients（112 ears） with large vestibular aqueduct syndrome were enrolled, the study time was from January 2017 to September 2018, the auditory brainstem response under four acoustic stimulation modes was implemented, guide clickABR, bone conduction clickABR, Tb-500 HzABR, Tb-1000 HzABR, and the short latency late reaction and short latency negative reaction extraction rate under different stimulation conditions were observed and evaluated. Results In 60 patients（112 ears）, a short latency negative response of 60 ears was found, with a percentage of 53.57%; In 60 patients, 4 patients with mild hearing loss were found, all of which led to a short latency negative reaction; There were 20 cases of hearing loss, 12 cases of short latency negative reaction, 30 cases of severe hearing loss, 16 cases of short latency negative reaction, 6 cases of extremely severe hearing loss, and 2 cases of short latency negative reaction. The extraction rate of 60 patients（112 ears） was 48.21%, after air-guided clickABR stimulation, 26.79% after Tb-500 Hz ABR stimulation, and 5.36% after boneguided clickABR stimulation, which was induced by Tb-1000 Hz ABR stimulation, the rate was 28.57%; there was a significant abnormality in the comparison of the above four results, and P〈0.05. Conclusion The short latency response of the guide click ABR acoustic stimulation mode has a higher extraction rate, which can provide an effective reference for early clinical diagnosis.
