To review the results of caloric test and the video head impulse test (vHIT) in a cohort of VM patients and assessed the value of each for predicting the prognosis in VM patients. A retrospective analysis was performed on VM patients in our vertigo clinic, vestibular function were assessed by caloric test and vHIT at the initial visit and 6 months after treatment. Complete response (CR) was defined as no need for continued medication, uncomplete response (UR) as improved symptoms but need for continued medication, no symptomatic improvement. At the initial evaluation, 15 of 75 (15.0%) exhibited abnormal caloric test results, 9 of 75 patients (12.0%) exhibited abnormal vHIT results. Six months later, 58 of 75 patients (77.3%) no longer required medication (CR), while 17 (22.7%）UR patients need for continued medication. The ratio of abnormal vHIT gain and abnormal caloric results were significantly different between group (CR) and group (UR) (<0.05). Abnormal vHIT and caloric test results revealed semicircular canal dysfunction in VM patients, peripheral vestibular abnormalities are closely related to the development of vertigo in VM patients and predicted prolonged preventive medication and vestibular rehabilitation requirement.
回顾一组梅尼埃病（VM）患者的冷热试验和视频头脉冲试验（vHIT）结果，并评估每项检查对预测VM患者预后的价值。对我院眩晕门诊的VM患者进行回顾性分析，在初诊时及治疗6个月后通过冷热试验和vHIT评估前庭功能。完全缓解（CR）定义为无需继续用药，不完全缓解（UR）定义为症状改善但仍需继续用药，无症状改善。在初始评估时，75例患者中有15例（15.0%）冷热试验结果异常，75例患者中有9例（12.0%）vHIT结果异常。6个月后，75例患者中有58例（77.3%）不再需要用药（CR），而17例（22.7%）UR患者仍需继续用药。组（CR）和组（UR）之间异常vHIT增益和异常冷热试验结果的比例有显著差异（<0.05）。异常的vHIT和冷热试验结果揭示了VM患者的半规管功能障碍，外周前庭异常与VM患者眩晕的发生密切相关，并预示着需要延长预防性用药和进行前庭康复治疗。
