摘　　要：目的记录中国空军战斗机飞行(学)员气导声诱发的oVEMP(ocular vestibular-evoked myogenic poten-tial,眼外肌上诱发的前庭肌源性电位)的特征性参数,以便建立战斗机飞行(学)员的正常值数据。方法 62名健康飞行学员(30名男性和32名年龄匹配的女性)和31名现役健康战斗机飞行员作为受试者,采用气导短纯音(short tone burst,STB)双侧给声双侧进行记录。记录93名健康飞行(学)员STB-oVEMP的nI和pI潜伏期、nI-pI间期、nI-pI的波间幅度以及双侧幅度不对称比,以获得正常值数据。对年龄与性别对oVEMP的影响也进行了观察。结果 93名健康飞行(学)员oVEMP的nI和pI潜伏期、nI-pI间期、nI-pI的波间幅度以及双侧幅度不对称比分别为(10.35±0.66)ms,(15.18±1.07)ms,(4.75±0.99)ms,(6.75±4.13)μV,以及(13.22±9.13)%。男性飞行学员与男性现役战斗机飞行员间在oVEMP的各个特征性参数上无显著差别。年龄匹配的男女性飞行学员仅在nI-pI的波间幅度上存在显著差别,分别为男性(6.96±3.85)μV和女性(5.47±3.10)μV。结论在oVEMP幅度上存在性别差异,年龄对oVEMP参数似乎没有影响。因此应该采用双侧幅度不对称比而不能仅仅采用绝对幅度参数来评估oVEMP的检测结果。飞行(学)员需要按照性别分别建立oVEMP的正常值范围。Objective To characterize air conduction sound induced oVEMPs in Chinese fighter pilots for normative data in this population. Methods Sixty two healthy student pilots（30 males and 32 age-matched females） and 31 healthy active-duty fighter pilots were recruited as study participants. oVEMPs were induced bilaterally using air-conduction short tone burst（STB） stimulation. The latencies of nI and pI, nI-pI interval, peak-to-peak nI-pI amplitude and asymmetry ratio were measured. Effects of gender and age on oVEMPs were examined. Results The latencies of nI and pI, nI-pI interval, peak-to-peak nI-pI amplitude and asymmetry ratio of STB-oVEMP in these healthy pilots and student pilots were 10.35 ± 0.66 ms, 15.18 ± 1.07 ms, 4.75 ± 0.99 ms, 6.75 ± 4.13 μV, and 13.22 ± 9.13 %, respectively. No significant difference existed between male student and active-duty fighter pilots in terms of the characteristic parameters of oVEMPs. The nI-pI amplitude was significantly different between age-matched male and female student pilots （6.96 ±3.85 μV vs. 5.47 ± 3.10 μV）. Conclusion Gender difference exists in oVEMP amplitude. Thus oVEMPs asymmetry ratio may be more important than absolute amplitude, and gender-appropriate normative oVEMPs data should be established.
