| 摘 要： | 目的:探讨视频眼震图(VNG)在良性阵发性位置性眩晕(BPPV)中的应用价值。方法:回顾126例BPPV患者的VNG资料,分析总结各型BPPV在Dix-Hallpike和滚转试验中VNG上的眼震特点。结果:126例BPPV患者中,后半规管BPPV(PSC-BPPV)98例(77.8%),水平半规管BPPV(HSC-BPPV)17例(13.5%),前半规管BPPV(ASC-BPPV)5例(3.9%),混合型BPPV6例(4.8%);28例PSC-BPPV记录到反转相眼震。VNG上显示PSC和ASC管石症Dix-Hallpike悬头位垂直相眼震分别向上、向下,水平相眼震均向对侧,回到坐位时眼震反向。HSC-BPPV滚转试验向两侧转头均可诱发出眼震,眼震与转头方向相同时,可判断为HSC管石症,以能够诱发较强眼震的转头侧为患侧;眼震与转头方向相反时,则为HSC嵴顶结石症,以能够诱发较弱眼震的转头侧为患侧。结论:VNG能够客观地记录BPPV患者的眼震情况,准确判断耳石所在的半规管,并且保存了眼震数据资料,可以进一步指导临床实践,值得推广。

| Abstract: | Objective:To analyze the value of positioning diagnosis of VNG (Videonystagmograph) in patients with benign paroxysmal positional vertigo(BPPV).Method:One hundred and twenty-six patients with BPPV were enrolled in this retrospective study. Their positional nystagmus recorded by VNG in Dix-Hallpike and roll tests were analyzed to summarize the characteristics of nystagmus on nystagmograph of various BPPV.Result:Of 126 patients with BPPV diagnosed in our center,the posterior semicircular canals(PSC) were invo... |
