背景和目的：偏头痛是一种非常普遍的原发性头痛疾病，经常伴有头晕、耳鸣和听力损失等平行症状。我们的目的是研究前庭偏头痛（VM）患者和健康人在视频头脉冲（vHIT）结果上的差异，同时考虑前庭眼反射（VOR）增益的平均值、代偿性跳眼潜伏期和振幅的发生。根据结果，确定vHIT在前庭偏头痛诊断中的有用性。方法：共纳入120例受试者，其中80例为前庭偏头痛患者，40例为年龄匹配的健康对照组。在评估过程中选取历史；进行了视频稳震仪和视频头脉冲测试。结果：与健康受试者组相比，VM组的扫视率要高得多，只有7.5%的VM组表现出较低的VOR增加，并伴有代偿性扫视，表明前庭功能障碍。结论：再固定眼跳是不同前庭病变的重要标志。vHIT结果有助于完成前庭偏头痛的全马赛克诊断。
BACKGROUND AND OBJECTIVE: Migraine is an extremely prevalent primary headache disorder that frequently associates parallel symptoms such as dizziness, tinnitus and hearing loss. Our aim is to investigate differences in video head impulse (vHIT) results with patients suffering from vestibular migraine (VM) and healthy people, taking into consideration mean values of vestibule ocular reflex (VOR) gain, occurrence of the compensatory saccades latency and amplitude. According to the results, determine the usefulness of vHIT in vestibular migraine diagnostics.METHODS: A total number of 120 subjects were enrolled in the study, 80 of them were vestibular migraine patients (VM), while the other 40 were a control group of age matched healthy subjects. History was taking during the evaluation; videonystagmography and the video head impulse test were done.RESULTS: The rate of saccades is much more higher in the VM group compared to the healthy subjects group, only 7.5% of the VM group showed a low VOR gain with compensatory saccades denoting a vestibular deficit.CONCLUSION: The refixation saccades are an important sign that could underlie different vestibular problems. vHIT result can contribute to the completion of full mosaic of vestibular migraine diagnostics.
