Significance of the reverse phase nystagmus for the diagnosis of benign paroxysmal positional vertigo

摘要: 目的:探讨变位试验中反转相眼震在良性阵发性位置性眩晕(BPPV)诊断中的意义。方法:118例BPPV 患者,其中在变位试验中出现反转相眼震26例,记录和分析其眼震参数,再综合病史特点,对耳石的责任半规管进行判断,并进行对应的耳石复位治疗(CRP),比较疗效差异是否有统计学意义。结果:出现反转相眼震的26例BPPV患者均拟诊为水平半规管后臂型管石症,其中右水平半规管型15例,左水平半规管型11例,CRP治疗显效4例,有效15例,无效7例, 对疗效进行单因素χ2检验,差异有统计学意义(χ2=7.46,P<0.05)。结论:对在变位试验中出现反转相眼震并拟诊为BPPV的患者,CRP的疗效差异有统计学意义,CRP治疗有效,治疗性诊断成立,对责任半规管的分析和判断有临床指导意义。

Abstract: Objective: To investigate the significance of the reverse phase nystagmus for the diagnosis of benign paroxysmal positional vertigo when going on the positioning test. Method: During the positioning test,there are 26 cases with reverse phase nystagmus in the 118 BPPV patients,note and analyse their nystagmus characteristics,then combine their disease history,to diagnose the affected side of the BPPV,and following with the corresponding treat of canalith repositioning procedure(CRP). Result: All the 26 cases with reverse phase nystagmus are the BPPV patients of horizontal semicircular postal-canalithasis,in which,RHSC-pCan for 15 cases,LHSC-pCan for 11 cases,with the treat of CRP,the significant effectivities are 4 cases,effectivities 15,uneffectivities 7,after single factor chi-square test,χ2=7.46,P<0.05.Conclusion: For the BPPV cases with reverse phase nystagmus during the positioning test,their efficacy difference of the CRP is significant statistically,that is the CRP treat is effective, the therapeutic diagnosis is established, which contributes to the analysis and judgment for the affected side of the semi- circular canals. -
