目的本研究的目的是根据患者年龄和脉冲方向确定视频头脉冲测试（vHIT）增益值的差异。方法所有参与者均接受水平半规管（HSCC）的vHIT。另外对 434 名参与者进行了垂直管（后半规管和前半规管 [PSCC 和 ASCC]）vHIT。结果 70 岁以下的 HSCC 患者和 80 岁以下的垂直管患者中平均前庭眼反射 (VOR) 增益保持不变（PSCC：0.965 0.12，ASCC：0.975） +/- 0.14）。然而，70 岁以上的 HSCC 患者（0.978 +/- 0.35，P < .001）和 80 岁以上的垂直管患者（PSCC：0.828 +/- 0.16，ASCC：0.851 +/- 0.13，P < .001）VOR 增益下降显着。另外，右向脉冲的VOR增益高于向左脉冲，但在垂直脉冲测试中，根据脉冲方向没有差异。结论VOR增益随着年龄的增加而下降，在水平运河上70岁以上，在垂直运河上80岁以上。此外，仅在右眼记录中，向右脉冲的水平VOR增益高于向左脉冲，但根据脉冲方向，垂直耳道没有显示增益差异。证据水平2b。喉镜，128：E228-E233，2018
ObjectiveThe aim of this study was to identify the difference of gain value in the video head impulse test (vHIT) according to the age of the patient and the direction of the impulse.MethodAll participants were subjected to vHIT with horizontal semicircular canal (HSCC). vHIT with vertical canal (posterior and anterior semicircular canal [PSCC and ASCC]) additionally was performed in 434 participants.ResultsThe mean vestibulo-ocular reflex (VOR) gain was maintained in patients in the HSCC at below 70 years (1.025 0.08) and in the vertical canal at below 80 years (PSCC: 0.965 0.12, ASCC: 0.975 +/- 0.14). However, the decrease of VOR gain was significant in patients over 70 years in the HSCC (0.978 +/- 0.35, P < .001) and in patients over 80 years in the vertical canal (PSCC: 0.828 +/- 0.16, ASCC: 0.851 +/- 0.13, P < .001). In addition, a VOR gain of rightward impulse was higher than the leftward impulse, but there was no difference based on the direction of impulse in the vertical impulse test.ConclusionVOR gain declines with increasing age, over 70 years on the horizontal canal, and over 80 years on the vertical canal. Additionally, horizontal VOR gain of rightward impulse was higher than the leftward impulse in right-eye recordings only, but the vertical canal showed no difference of gain according to the direction of impulse.Level of Evidence2b.
