视频眼震图监视下的良性阵发性位置性眩晕手法复位临床分析

Clinical study of canalith repositioning procedure under video-nystagmography in dealing with benign paroxysmal positional vertigo

目的探讨良性阵发性位置性眩晕(benignparoxysmal positional vertigo,BPPV)手法复位的临床疗效及视频眼震图在复位中的作用。方法回顾性分析来我科就诊疑似BPPV患者200例,所有患者均分别在裸眼下和视频眼震图下通过变位试验共确诊159例并行手法复位治疗,统计裸眼下与视频眼震图下典型特征眼震的检出率及手法复位的临床治愈率及复发率。结果裸眼下特征眼震的检出率为68.50%,视频眼震图下典型眼震检出率为79.50%。手法复位第一次治愈率为77.99%,总有效率为98.11%,复发率为5.66%,复发患者经再次手法复位后均好转。结论视频眼震图在BPPV诊断及手法复位中起着重要作用,手法复位为治疗BPPV可靠而有效的方法。

OBJECTIVE To investigate the clinical effect of canalith repositioning procedure in dealing with Benign paroxysmal positional vertigo and the contribution of video-nystagmography in the procedure.METHODS 200 cases of patients with suspected benign paroxysmal positional vertigo wer retrospectively analysed.Posture test was conducted for all the patients,nystagmus were recorded respectively both under naked eye and videonystagmography.159 of them were finally diagnosed and canalith repositioning procedure was conducted,then cure rate and relapse rate were analysed statistically.RESULTS The detection rate under naked eye check were 68.50% while the rate under video-nystagmography were 79.50%.the first time canalith repositioning cure rate was 77.99%,the total cure rate was 98.11%,relapse rate was 5.66%.All the relapse patients were cured finally.CONCLUSION Canalith repositioning procedure was proofed to be a reliable and effective way in dealing with benign paroxysmal positional vertigo and Videonystagmography played a important role in the procedure.
