摘要

摘要: 目的:探讨健康青年人群气导短纯音诱发的眼肌前庭诱发肌源性电位(oVEMP)的特征性参数,并进行参数分析及正常值的计算。方法:55例健康青年人作为受试者,均采用500 Hz气导短纯音单侧给声对侧记录。记录55例(110耳)的P1-N1复合波引出阈值,P1和N1的潜伏期,P1-N1波间期及P1-N1复合波振幅,以获得临床正常值范围,同时分析性别对oVEMP各参数的影响。结果:55例(110耳)均引出典型的P1-N1复合波,引出率为100%。oVEMP的引出阈值(正常听力级nHL)为(82.23±2.92)dBHL;95 dBHL气导短纯音刺激下获得P1的潜伏期(11.53±0.80)ms;N1的潜伏期(16.61±0.87)ms,P1-N1波间期(5.18±1.04)ms,P1-N1复合波振幅(5.96±2.59)μV。31例男性受试者P1-N1复合波振幅为(6.49±2.67)μV,24例女性为(5.28±2.34)μV,二者比较差异有统计学意义(P<0.05)。结论:气导短纯音诱发的oVEMP是一种新兴的前庭功能检测方法,在oVEMP的P1-N1复合波振幅上存在性别差异,应按照性别分别建立oVEMP的正常值范围。

Abstract: Objective: To investigate the characteristics of air-conducted ocular vestibular-evoked myogenic potential (oVEMP) in healthy young people , so as to establish the normative data of young people. Method: Fifty-five healthy young subjects were recruited as study participants, 500 Hz air-conducted tone burst was used as stimulation.The threshold of oVEMP in each ear was examined. The latencies of P1 and N1,P1-N1 interval,peak-to-peak of P1-N1 amplitude and asymmetry ratio were measured.Effects of gender on oVEMPs were also examined. Result: The typical complex wave of N1 and P1 was observed in all subjects.The threshold of oVEMP examination was(82.23±2.92) dBHL,95 dBHL air-conducted get the latencies of P1and N1,P1-N1 interval,peak-to-peak P1-N1 amplitude in these healthy young people were(11.53±0.80)ms,(16.61±0.87)ms,(5.18±1.04)ms,(5.96±2.59)μv,respectively. The peak-to-peak P1-N1 amplitude of male was (6.49±2.67) μv,the female was (5.28±2.34) μv, there were significant differences between male and female subjects in the wave amplitude (P<0.05). Conclusion: Air-conduction induced oVEMP is a new method for vestibular function test. The amplitude of the oVEMP wave was different between male and female. Therefore it is necessary to establish the normal value according to genders.
