To investigate differences in vestibular evoked myogenic potentials (VEMP) results with patients suffering from vestibular migraine and healthy people, taking into consideration values of threshold and latency of occurrence of the characteristic wave complex, size of amplitude, and interaural amplitude ratio. According to the results, determine the importance and usefulness of VEMP in vestibular migraine diagnostics.
A total number of 62 subjects were included in the study, 32 of them belonging to a group of patients suffering from vestibular migraine (VM), while other 30 were in a control group of healthy subjects. Information was collected during the diagnostic evaluation. General and otoneurological history of patients and bedside tests, audiological results, videonystagmography and cervical vestibular evoked myogenic potentials (cVEMP) were made.
There was a difference in an interaural ratio of amplitudes in the experimental and control groups, but it was not found to be clinically significant. By ToneBurst 500 Hz method, the interaural amplitude ratio higher than 35% was measured in 46.97% subjects, while the response was totally unilaterally missing in 28.8% patients.
Even the sophisticated method as cVEMP does not give the ultimate result confirming the vestibular migraine diagnosis, and neither do other diagnostic methods. cVEMP result can contribute to the completion of full mosaic of vestibular migraine diagnostics.
研究前庭性偏头痛患者与健康人的前庭诱发肌源性电位(VEMP)结果差异,考虑特征波复合体出现的阈值和潜伏期值、振幅大小及双耳间振幅比。根据结果,确定VEMP在前庭性偏头痛诊断中的重要性和实用性。
本研究共纳入62名受试者,其中32名属于前庭性偏头痛(VM)患者组,另外30名属于健康受试者对照组。在诊断评估过程中收集信息。记录患者的一般情况、耳神经学病史及床边检查、听力学结果、视频眼震图和颈前庭诱发肌源性电位(cVEMP)。
实验组和对照组的双耳间振幅比存在差异,但未发现具有临床意义。采用500Hz短纯音方法,46.97%的受试者双耳间振幅比高于35%,28.8%的患者反应完全单侧缺失。
即使像cVEMP这样精密的方法也不能给出确诊前庭性偏头痛的最终结果,其他诊断方法也不行。cVEMP结果有助于完善前庭性偏头痛诊断的全貌。
