【摘要】：目的:分析良性阵发性位置性眩晕(BPPV)变位试验假阴性的比例和原因。方法:回顾性分析2009-02-2009-04期间就诊于北京大学人民医院耳鼻咽喉科门诊具有BPPV典型临床症状、变位试验确诊、经过复位治疗痊愈的68例BPPV患者的资料。所有患者均行变位试验检查,首次变位试验诱发出典型眼震者为阳性组;首次检查阴性的患者,摇头后或隔日复诊再次变位试验检查均获得典型眼震为假阴性组,经过复位治疗症状痊愈。结果:13例(19.12%)患者首次变位试验出现阴性,经过反复变位试验,出现阳性,其中11例在检查当天摇头后再次变位试验出现典型眼震者,2例隔日复诊变位试验出现典型眼震。假阴性组年龄、性别、病程、半规管类型与阳性组差异无统计学意义(P0.05)。结论:对临床疑为BPPV但变位试验阴性的患者,建议摇头后再次检查并随访复查以获得典型眼震明确诊断。
[Abstract]:Objective: to analyze the false negative rate and causes of (BPPV) transposition test in benign paroxysmal positional vertigo. Methods: the clinical data of 68 BPPV patients who were diagnosed by transposition test and were diagnosed by transposition test during 2009-02-2009-04 were analyzed retrospectively in the department of otolaryngology and otolaryngology of people's Hospital of Peking University. All patients were examined by displacement test, the first transposition test induced typical nystagmus as positive group, and the patients who were negative for the first time were found to be false negative group after shaking their head or the next day. The symptoms were cured after reduction. Results: 13 cases (19.12%) were negative in the first transposition test. After repeated translocation test, 11 cases had typical nystagmus after shaking their head on the same day, and 2 cases had typical nystagmus in the second transposition test every other day. There was no significant difference in age, sex, course, semicircular canal type between false negative group and positive group (P0.05). Conclusion: it is suggested that the patients suspected to be BPPV but negative for transposition test should be examined again and followed up to obtain a definite diagnosis of typical nystagmus.
