摘要

目的

研究不同刺激声在坐姿下诱发的前庭诱发肌源性电位（vestibular-evoked myogenic potentials，VEMPs）特征，提供各波潜伏期及振幅等参数的正常值参考范围。

方法

分别用500 Hz短纯音（tone-burst）及500 Hz 线性调频脉冲音（CE-chirp）两种刺激声对21名（男11人，女10人）听力正常且无耳蜗及前庭系统疾病的青年人（年龄22～33岁，平均年龄23.95±3.29岁）进行VEMPs测试，测试起始强度为110 dB nHL，以5 dB为步阶测试至阈值，记录各强度参数，并进行分析。

结果

两种刺激声坐姿下诱发的cVEMP及oVEMP阈值分别为tone-burst cVEMP 85.00±6.10 dB nHL，CE-chirp cVEMP 84.63±4.99 dB nHL；tone-burst oVEMP 83.38±6.54 dB nHL，CE-chirp oVEMP 82.50±6.20 dB nHL。两种刺激声测得的各强度p1潜伏期、n1潜伏期有显著差异（

＜0.05），p1-n1波间期、p1-n1振幅、双侧不对称性、双侧振幅比、双侧对称系数等均无显著差异（

＞0.05）。

结论

坐姿下正常青年人两种刺激声给声强度100 dB nHL时VEMPs的引出率均为100%，500 Hz线性调频脉冲音可作为VEMPs测试的刺激声应用于临床，评估椭圆囊和球囊功能。

Abstract

Objective

To observe the normal range of Vestibular-evoked myogenic potentials (VEMPs) by 500 Hz CE-chirp and 500 Hz tone-burst stimuli in sitting position.

Methods

21 normal hearing adult volunteers (42 ears

11 males and 10 females) included (without ear diseases). 500 Hz tone-burst and 500 Hz CE-chirp stimuli were used to conduct VEMPs. The intensity began from 110 dB nHL to threshold

5 dB as a step. We recorded and analyzed each data by different intensities.

Results

The thresholds of cVEMP and oVEMP by different stimulations were as followed: Tone-burst cVEMP (85.00±6.10) dB nHL

CE-chirp cVEMP (84.63±4.99) dB nHL. Tone-burst oVEMP (83.38±6.54) dB nHL

CE-chirp oVEMP

(82.50±6.20) dB nHL. The p1 and n1 latency of different stimulations had significant differences (

0.05). The p1-n1 interval latency

p1-n1 amplitude

inter-aural asymmetry and bilateral amplitude ratio found no statistically difference (

0.05).

Conclusion

In the sitting position

The extraction rate of VEMPs was 100% in normal young people when two kinds of stimuli were given to 100 dB nHL

CE-Chirp can be used as the stimulus sound of VEMPs test in clinic to evaluate the function of utricle and saccule.
