摘要
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(P<0.05).The p1-n1 interval latency,p1-n1 amplitude,inter-aural asymmetry and bilateral amplitude ratio found no statistically difference(P>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.关键词
