Abstract

Background: Treatment with a cochlear implant (CI) poses the risk of inducing a behaviorally unmeasurable air-bone gap leading to false negative absence of cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) to air conducted sound (ACS).

Objective: To investigate VEMP response rates to ACS and bone conducted vibration (BCV) in CI patients and the applicability of the B81 transducer for BCV stimulation.

Methods: Prospective experimental study including unilateral CI patients, measuring cVEMPs and oVEMPs to ACS and to BCV, comparing response rates, signed asymmetry ratios, latencies, and amplitudes.

Results: Data of 13 CI patients (mean age 44±12 years) were analyzed. For the CI side, oVEMP and cVEMP response rates were significantly higher for BCV (77%cVEMP, 62%oVEMP) compared to ACS (23%cVEMP, 8%oVEMP). For the contralateral side, no difference between response rates to ACS (85%cVEMP, 69%oVEMP) and BCV (85%cVEMP, 77%oVEMP) was observed. Substantially higher asymmetries were observed for ACS (-88±23%for cVEMPs, -96±11%for oVEMPs) compared to BCV (-12±45%for cVEMPs, 4±74%for oVEMPs).

Conclusions: BCV is an effective stimulus for VEMP testing in CI patients. The B81 is a feasible stimulator.

骨传导振动是人工耳蜗耳石检测的有效刺激。

背景:人工耳蜗(CI)治疗存在诱导行为上不可测量的气骨间隙的风险，导致颈和眼前庭诱发肌源性电位(cemps, oVEMPs)对空气传导声(ACS)的假阴性缺失。目的:探讨CI患者VEMP对ACS和骨传导振动(BCV)的反应率及B81换能器对BCV刺激的适用性。方法:前瞻性实验研究，包括单侧CI患者，测量cveemps和oVEMPs到ACS和BCV，比较反应率、签名不对称比、潜伏期和振幅。结果:分析了13例CI患者的资料，平均年龄44±12岁。在CI方面，BCV的oVEMP和cVEMP缓解率(77%cVEMP, 62%oVEMP)明显高于ACS (23%cVEMP, 8%oVEMP)。对于对侧，ACS (85%cVEMP, 69%oVEMP)和BCV (85%cVEMP, 77%oVEMP)的有效率无差异。与BCV (cVEMPs为-12±45%，oVEMPs为4±74%)相比，ACS (cVEMPs为-88±23%，oVEMPs为-96±11%)的不对称性明显更高。结论:BCV是CI患者VEMP检测的有效刺激物。B81是一种可行的刺激器。

期刊介绍： Journal of Vestibular Research is a peer-reviewed journal that publishes experimental and observational studies, review papers, and theoretical papers based on current knowledge of the vestibular system. Subjects of the studies can include experimental animals, normal humans, and humans with vestibular or other related disorders. Study topics can include the following: Anatomy of the vestibular system, including vestibulo-ocular, vestibulo-spinal, and vestibulo-autonomic pathways Balance disorders Neurochemistry and neuropharmacology of balance, both at the systems and single neuron level Neurophysiology of balance, including the vestibular, ocular motor, autonomic, and postural control systems Psychophysics of spatial orientation Space and motion sickness Vestibular rehabilitation Vestibular-related human performance in various environments
