良性陣發(fā)性位置性眩暈變位試驗(yàn)假陰性原因分析
[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.
