Objective:To improve the level of clinical diagnosis and treatment of idiopathic bilateral vestibulopathy（IBV） by investigating the clinical characteristics of this disease. Method:Retrospective analysis was performed on patients with IBV diagnosed, excluding patients with clear primary factors, and including IBV patients with unknown causes, to analyze their clinical symptoms and vestibular function examination results. Result:In this group of cases, three cases were in line with the diagnosis of IBV. The clinical manifestations included imbalance, oscillopsia, and normal hearing level, which cannot be explained by other diseases. The vestibular function testing of the patients with IBV showed bilateral reduced response in caloric tests, positive response in video head impulse test, and decreased score in sensory organization test. Vestibular rehabilitation therapy were carried for these patients, and could improve the patients' symptoms. Conclusion:IBV has typical clinical manifestations. Vestibular function testing indicates bilateral vestibular dysfunction. Other diseases with bilateral vestibulopathy should be excluded for diagnoses, and vestibular rehabilitation therapy is one of the appropriate treatments.
目的：回顾性分析特发性双侧前庭病（IBV）患者的临床特征，提高该病的临床诊治水平。 方法：分析明确诊断的双侧前庭病患者，排除有明确原发因素者，纳入原因不明的双侧前庭病患者，分析其临床症状及前庭功能检查结果。 结果：有3例符合IBV诊断。临床表现为活动时平衡功能下降、振动幻视，听力均正常，上述症状不能由其他疾病解释。患者前庭功能检查表现为冷热试验中双侧反应低下，视频头脉冲试验示双侧阳性（增益降低及出现回复性扫视），平衡功能降低；通过前庭康复治疗症状改善。 结论：IBV具有典型的临床表现，前庭功能检查提示存在双侧前庭功能低下，诊断时需排除其他疾病，前庭康复是合适的治疗方法。.
