2023年临床耳鼻咽喉头颈外科杂志37卷6期J Clin Otorhinolaryngol Head Neck Surg(China)*409*孤立性耳石器功能障碍诊断专家共识中国医药教育协会眩晕专委会[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OD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OD的临床诊疗工作，[关键词]前庭疾病：耳石疾病：眩晕D0I:10.13201/j.issn.2096-7993.202306002[中图分类号]R764[文献标志码]AExpert consensus on the diagnosis of isolated otolith dysfunctionSpecial Com mittee on Vertigo of China Medical Education AssociationCorresponding author:WU Ziming,College of Otolaryngology Head and Neck Surgery,Chi-nese PLA General Hospital,Chinese PLA Medical School,Beijing,100853,China.E-mail:zimingwu@126 com;LIU Bo,Department of Otorhinolaryngology-Head and Neck Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,430022,China,E-mail:liuboent@hust edu cnAbstract Isolated otolith dysfunction(iOD)involves a group of unexplained vestibular syndromes that mani-fest clinically as a sense of translation,tilting or floating,and blurred vision with head movement,with normalsemicircular canal function but abnormal otolith function on laboratory vestibular testing.As vestibular medicinehas 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 thediagnosis of this disease in China.In this context,the Special Committee on Vertigo of China Medical EducationAssociation organized a group of domestic experts in vestibular medicine and formulated this diagnostic consensusafter thorough discussion based on the latest evidence in China and abroad,in order to promote the best clinicalpractice for iOD.Key words vestibular medicine:otolith disorder:vertigo每侧内耳前庭终器包括3个半规管壶腹和1定义2个耳石器，半规管壶腹感受机体旋转运动，而孤立性耳石器功能障碍(isolated otolith dys2个耳石器，椭圆囊和球囊感受直线加速度运动。function,iOD)是一组原因不明的前庭综合征，临临床上，有一些眩晕或头晕患者表现为平移、倾斜床表现为平移、倾斜或禄浮感以及头部活动时的视等症状，而非视物旋转等常见的前庭症状。这一类敏度下降，前庭功能检查显示半规管功能正常但耳患者的前庭功能检查并未显示半规管功能受损，而石器功能异常，需排除其他前庭疾病。iOD曾被称为耳石器的损伤。随若前庭医学的临床实践开展，为特发性耳石器性眩晕]、特发性耳石器特异性这些症状的患者逐渐求诊于眩晕头晕门诊。这类前庭功能障碍)、特发性椭圆囊功能障碍等。以孤立性耳石器功能受损的病例报道也逐渐增加，2流行病学近来，国际上相关的临床研究和诊断标准亦见诸报由于各家报道采用的诊断标准不一，目前尚无道。为提高对本前庭综合征的认识，规范临床工确切的流行病学研究资料。国外回顾性研究报道作，特制定本共识。显示，在眩晕专科门诊以头晕为主诉的患者中，iOD占比约为2%]。通信作者：吴子明，中国人民解放军总医院耳鼻咽喉头颈外科医学部，北京，100853，Emil:zimingwu@126.com刘波，华中科技大学同济医学院附属协和医院耳鼻咽喉头颈外科，或汉，430022，E-mail:liub0ent@hust.du.cm引用本文：中国医药教有协会眩晕专委会.孤立性耳石器功能障碍诊断专家共识[J门.临床耳鼻咽喉头颈外科杂志，2023,37(6):409414D01:1013201/j.issn.2096-7993.202306002.
