Abstract:
Isolated otolith dysfunction(iOD) involves a group of unexplained vestibular syndromes that manifest clinically as a sense of translation, tilting or floating, and blurred vision with head movement, with normal semicircular canal function but abnormal otolith function on laboratory vestibular testing. As vestibular medicine has gained widespread popularity in recent years, increasing attention has also been paid to iOD and case reports, clinical studies and diagnostic criteria have been published. However, there is no consensus document to guide the diagnosis of this disease in China. In this context, the Special Committee on Vertigo of China Medical Education Association organized a group of domestic experts in vestibular medicine and formulated this diagnostic consensus after thorough discussion based on the latest evidence in China and abroad, in order to promote the best clinical practice for iOD.
摘要: 孤立性耳石器功能障碍(isolated otolith dysfunction,iOD)是一组原因不明的前庭综合征,临床表现为平移、倾斜或漂浮感以及头部活动时的视敏度下降,前庭功能检查显示半规管功能正常但耳石器功能异常。随着前庭医学临床实践的广泛开展,对iOD的关注逐渐增加,国际上相关的病例报道、临床研究和诊断标准亦见诸报道。且在临床实践中,国内尚无共识文件指导该疾病的临床工作。在此背景下,中国医药教育协会眩晕专委会组织国内多名前庭医学专家,经过多次讨论,在参考借鉴国内外最新研究成果的基础上制定本诊断共识,以期规范开展iOD的临床诊疗工作。.
