眼前庭诱发肌源性电位（oVEMP）和颈VEMP （cemp）是较新的诊断方法，可以深入了解耳石感觉。我们的目的是确定重新定位手术成功后VEMP波复合体某些参数的变化，作为良性阵发性位置性眩晕（BPPV）患者恢复状态的指标。这可能证实了耳石回归耳石感觉领域的理论。本研究纳入48例单侧后半规管BPPV患者。在他们第一次到达时，进行了耳神经检查、oVEMP和cemp测试。在成功实施Epley演习后的7天和6个月的后续检查中也包括了同样的内容。最初的测量显示受影响一侧的oVEMP幅度明显降低。在第7天的测量中，患侧的幅度增加，幅度比显著降低（p=0.693），在第6个月的最后一次测量时达到统计学意义（p=0.006）。这些发现证实了耳蜗返回脑室区的假设。
Ocular vestibular evoked myogenic potentials (oVEMP) and cervical VEMP (cVEMP) are newer diagnostic methods, which allow an insight into the otolith senses. Our aim was to determine changes in certain parameters of the VEMP wave complex after successfully performed repositioning procedure, as an indicator of the state of recovery in patients with benign paroxysmal positional vertigo (BPPV). This may confirm the theory of otolith returning into the area of otolithic senses. The study included 48 patients with unilateral posterior semicircular canal BPPV. On their first arrival, otoneurological examinations, oVEMP and cVEMP tests were performed. The same were included in follow up check-ups scheduled at seven days and six months after successful implementation of Epley maneuvers. The initial measurement revealed a significantly reduced amplitude of oVEMP on the affected side. On the 7-day measurement, the amplitude increase was observed on the affected side, with significant reduction in the amplitude ratio (p=0.693), which reached statistical significance on the last measurement at 6 months (p=0.006). These findings confirmed the hypothesis of the return of otoconia into the utricular area.
