Air conducted (AC) cervical vestibular evoked myogenic potentials (AC cVEMP) and air conducted ocular VEMP (AC oVEMP) may be used for measurement of otolith function. However AC oVEMP are few examined till now. The aim of this pilot study was to apply a method for use of AC oVEMP in clinical practice.
AC oVEMP were recorded in healthy voluntary people (n=20) using intense AC-sound stimulation (500 Hz tone bursts, 100 dB nHL). Thermal irrigation and AC cVEMP were normal as including criteria. Values were evaluated statistically.
AC oVEMP were recorded in all healthy patients. Mean and standard deviation for the first negative peak was 11.35±1.00 ms and for the first negative peak 16.30±1.10 ms. The mean amplitudes were 7.70±4.50 μV. The stability of n10 and p15 component was the same.
AC oVEMP can be easy and fast obtained. N10 and p15 latencies may used as parameter for clinical interpretation. Amplitude fluctuations are relatively large. Results can be used in further clinical investigation of AC oVEMP.
气导（AC）颈肌前庭诱发肌源性电位（AC cVEMP）和气导眼震电图（AC oVEMP）可用于测量耳石功能。然而，迄今为止对AC oVEMP的研究较少。本初步研究的目的是应用一种在临床实践中使用AC oVEMP的方法。
使用高强度AC声音刺激（500Hz短纯音，100dB nHL）在20名健康志愿者中记录AC oVEMP。热灌注和AC cVEMP正常作为纳入标准。对数值进行统计学评估。
所有健康患者均记录到AC oVEMP。第一个负峰的平均和标准差为11.35±1.00ms，第一个正峰为16.30±1.10ms。平均波幅为7.70±4.50μV。n10和p15成分的稳定性相同。
AC oVEMP可轻松快速获得。N10和p15潜伏期可作为临床解释的参数。波幅波动相对较大。结果可用于AC oVEMP的进一步临床研究。
