BACKGROUND This study aims to investigate the clinical value of two kinds of vestibular-evoked myogenic potentials in patients with sudden sensorineural hearing loss (SSNHL). METHODS A total of 82 patients were divided into two groups: vertigo group and non-vertigo group. All patients underwent examinations for pure tone hearing thresholds, middle ear analysis, the videonystagmography, caloric tests, and vestibular-evoked myogenic potentials elicited from the sternocleidomastoid and extraocular muscle. In addition, 30 healthy subjects were selected as the control group. RESULTS For the 30 healthy subjects, the average latency of p13 and n23 of the cervical vestibular evoked myogenic potentials (cVEMPs) were 13.13 ± 2.89 ms and 23.51 ± 3.25 ms, respectively, and the bilateral amplitude asymmetry rate ranged within 0.05-0.31. The average latency of n10 of the ocular vestibular evoked myogenic potentials (oVEMPs) was 10.13 ± 0.48 ms. The average amplitude of the n10-p15-wave was 5.58 ± 0.65 μV. Among the 35 vertigo patients with SSNHL, 27 patients had normal cVEMP and oVEMP examination results, five patients had abnormal oVEMP examination results, and five patients had abnormal cVEMP examination results. The latency and amplifier of oVEMPs and cVEMPs were within the normal range in 47 SSNHL patients without vertigo. The chi-square value was 5.647, the P-value was equal to 0.017, and the difference was statistically significant at a confidence interval of 95%. CONCLUSIONS OVEMPs and cVEMPs can be used evaluate the vestibular nerve function of SSNHL patients with vertigo.

前庭诱发肌源性电位测试对突发感音神经性听力损失患者的临床价值。



背景本研究旨在探讨两种前庭诱发肌源性电位对突发性听力损失(SSNHL)患者的临床价值。方法82例患者分为眩晕组和非眩晕组两组。所有患者均接受了纯音听力阈值、中耳分析、视频眼震图、热量测试以及从胸锁乳突肌和眼外肌引出的前庭诱发肌源性电位的检查。另外,选取30名健康受试者作为对照组。结果 30例健康受试者颈前庭诱发肌源性电位(cVEMP)p13和n23的平均潜伏期分别为13.13±2.89 ms和23.51±3.25 ms,双侧振幅不对称率范围在0.05~0.31之间。眼前庭诱发肌源电位 (oVEMP) 的 n10 平均潜伏期为 10.13 ± 0.48 ms。 n10-p15 波的平均振幅为 5.58 ± 0.65 μV。 35例SSNHL眩晕患者中,27例cVEMP和oVEMP检查结果正常,5例oVEMP检查结果异常,5例cVEMP检查结果异常。 47 例无眩晕的 SSNHL 患者中 oVEMP 和 cVEMP 的潜伏期和放大率均在正常范围内。卡方值为 5.647,P 值为 0.017,在 95% 的置信区间内差异具有统计学显着性。结论 OVEMPs和cVEMPs可用于评估SSNHL眩晕患者的前庭神经功能。
