The purpose of this study is to investigate the effectiveness of the high-frequency rotational test for discrimination of patients with decompensated from those with compensated Meniere's disease.
Patients with unilateral Meniere's disease were divided into two groups (compensated and decompensated), based on the presence of clinically significant positional nystagmus as a determinant of the compensation status. All patients and subjects underwent pure tone audiometry, video nystagmography, and the vestibular autorotation test (VAT). The gain, phase, and asymmetry values of VAT were evaluated to range between 2 and 6 Hz.
Phase values of horizontal vestibulo-ocular reflex (VOR) at 2.0, 2.3, and 2.7 Hz were significantly higher in the decompensated group (p<0.05). There was no significant difference in gain values, phase values, of vertical VOR and horizontal asymmetry values.
Our study confirmed that horizontal phase values were determined as sensitive markers in VAT to discriminate decompensated from compensated Meniere's disease.
本研究旨在探讨高频旋转测试在鉴别代偿性和失代偿性梅尼埃病患者方面的有效性。
根据临床显著位置性眼球震颤作为代偿状态决定因素，将单侧梅尼埃病患者分为两组（代偿组和失代偿组）。所有患者和受试者均进行纯音测听、视频眼震图和前庭自旋转测试（VAT）。评估 VAT 的增益、相位和不对称值的范围为 2 至 6 Hz。
在 2.0、2.3 和 2.7 Hz 时，水平前庭眼反射（VOR）的相位值在失代偿组中显著更高（p<0.05）。增益值、垂直 VOR 的相位值、水平不对称值没有显著差异。
我们的研究证实，水平相位值是 VAT 中鉴别代偿性和失代偿性梅尼埃病的敏感标志物。
