Masseter vestibular evoked myogenic potentials (mVEMP) involve the connection between the vestibular complex and trigeminal nerve nuclei. Given the theory that migraine is caused by increased activation of the trigeminal nerve, it is believed that mVEMP responses may have influenced in migraine patients.
The study included 20 individuals with migraine and 20 healthy controls. Latency, amplitude, and interaural amplitude asymmetry ratio of mVEMP responses recorded in migraine patients were compared with control group.
Considering the mVEMP normalization study conducted by Başöz et al. (2021) in a similar age group and in the same clinic, latency prolongation and amplitude decrease were observed in subjects with migraines. Migraine is considered a central pathology, as shown in the cervical and ocular VEMP (cVEMP/oVEMP) literature. No difference was observed in the interaural amplitude asymmetry ratio, which is important in peripheral pathologies. Additionally, when the number of pathological ears was examined in order to understand the total exposure, it was observed that the number of pathological ears was significantly higher in the migraine group.
In future studies, using mVEMP together with cVEMP and oVEMP tests, which allow evaluation of otolith organs and vestibular nuclei, will be valuable in determining the lesion location.
咀嚼肌前庭诱发肌源性电位（mVEMP）涉及前庭复合体与三叉神经核之间的联系。鉴于偏头痛是由三叉神经激活增加引起的理论，认为 mVEMP 反应可能会受到偏头痛患者的影响。
该研究纳入了 20 名偏头痛患者和 20 名健康对照者。比较偏头痛患者和对照组 mVEMP 反应的潜伏期、振幅和耳间振幅不对称比。
考虑到 Başöz 等人（2021 年）在相似年龄组和同一诊所进行的 mVEMP 正常化研究，偏头痛患者的潜伏期延长和振幅降低。偏头痛被认为是一种中枢病理学，正如颈椎和眼 mVEMP（cVEMP/oVEMP）文献中所显示的那样。在耳间振幅不对称比方面没有观察到差异，这在周围病理学中很重要。此外，为了了解总体暴露情况，检查了病理性耳的数量，结果发现偏头痛组的病理性耳数量明显更高。
在未来的研究中，使用 mVEMP 与 cVEMP 和 oVEMP 测试相结合，这可以评估耳石器官和前庭核，对于确定病变部位将是有价值的。
