SRM-Ⅳ型前庭功能诊疗系统对良性阵发性位置性眩晕的疗效观察

Treatment effect of SRM-Ⅳ vestibular function diagnosis system on benign paroxysmal positional vertigo

目的探讨SRM-Ⅳ型前庭功能诊疗系统对良性阵发性位置性眩晕(benign paroxysmal position vertigo,BPPV)的治疗效果。方法回顾性分析2015年1月至2016年3月于本院眩晕门诊就诊并接受手法复位的280例BPPV患者(手法复位组)以及2016年4月至2016年8月于本院就诊并接受SRM-Ⅳ复位的311例BPPV患者(SRM-Ⅳ复位组)的临床资料,采用卡方检验比较两组患者不同病变部位复位的疗效、1个月内残余头晕症状发生率及6个月内的复发率。结果 SRM-Ⅳ复位组患者治疗有效率显著高于手法复位组(96.5%︰91.1%,P<0.05);其中后半规管BPPV患者手法复位和SRM-Ⅳ复位有效率分别为94.6%和99.2%,差异具有显著性(P=0.028);水平半规管BPPV患者手法复位和SRM-Ⅳ复位有效率分别为90.3%和98.8%,差异具有显著性(P=0.019)。水平半规管BPPV手法复位组患者的残余头晕症状发生率显著高于SRM-Ⅳ复位组(38.9%︰18.5%,P=0.005);后壶腹嵴和水平半规管的手法复位6个月内BPPV复发率均高于SRM-Ⅳ复位(23.8%︰3.7%,23.6%︰7.4%;P分别为0.007、0.005)。结论 SRM-Ⅳ型前庭功能诊疗系统的应用提高了BPPV的临床疗效,尤其在水平半规管BPPV的治疗中具有更高的有效率,并且降低了残余头晕症状的发生率及治疗后6个月的复发率。

Objective To access the treatment effect of SRM-Ⅳ vestibular function diagnosis system on benign paroxysmal position vertigo（BPPV） patients. Method Clinical data of 280 patients with traditional gimmick reset treatment（gimmick reset group） from January 2015 to March 2016 and 311 patients with automatic reset treatment by SRM-Ⅳ vestibular function diagnosis system（SRM-Ⅳ group） from April to August 2016 in our hospital were retrospectively analyzed. The rates of treatment effects, remnant vertigo symptom and relapse in 6 months after reset on different diseased regions were analyzed between the two groups with Chi-squared test. Result The effective rate in SRM-Ⅳ group was significantly higher than gimmick reset group（96.5% ︰ 91.1%, P〈0.05）. The effective rate of the posterior semicircular duct BPPV with traditional gimmick reset and SRM-Ⅳ reset were 94.6% and 99.2%（P = 0.028）, which were 90.3% and 98.8% of horizontal semicircular canal BPPV（P = 0.019）. The rate of remnant vertigo symptom of horizontal semicircular canal BPPV with traditional gimmick reset was higher than SRM-Ⅳ reset（38.9% ︰ 18.5%, P =0.005）. The rate of relapse in 6 months after reset of posterior crista ampullaris and horizontal semicircular canal BPPV with traditional gimmick reset were higher than SRM-Ⅳ reset（23.8% ︰ 3.7%, 23.6% ︰ 7.4%; P = 0.007, 0.005 respectively）. Conclusion The treatment effects of SRM-Ⅳ vestibular function diagnosis system on BPPV is superior to traditional gimmick reset, especially in horizontal semicircular canal BPPV, and SRM-Ⅳ vestibular function diagnosis system could reduce the rates of remnant vertigo symptom and relapse in 6 months after reset in horizontal semicircular canal BPPV.
