目的 研究特发性水平半规管良性阵发性位置性眩晕复位次数、前庭冷热试验、复位后残余眩晕是否与复发率存在关系。 方法：2016年1月至2018年1月门诊手法复位成功的84位特发性水平半规管良性阵发性位置性眩晕（HSC-BPPV）的患者纳入本研究，所有患者均行Barbecue滚转手法复位。根据复位次数分为A组（＜3次）和B组（≥3次）；根据患者复位后有无残余眩晕，分为C组（无残余眩晕组）和D组（残余眩晕组），观察复发率。所有患者均行前庭冷热试验检查。结果 本研究显示A组(20.9%)和B组(26.8%)的复发率无明显差异；C组（11.8%）和D组（32%）复发率具有统计学意义（P=0.033）；复位后存在残余眩晕患者前庭功能异常率高；复位后存在残余眩晕并伴有前庭冷热试验异常的患者复发率最高(66.7%）；复发率最低的为复位次数＜3次且复位后无残余眩晕的患者（6.3%）。 结论 水平半规管BPPV复发率与复位次数无关，冷热试验异常与残存眩晕相关，复位后残余眩晕伴前庭冷热试验异常提示患者复发率增高。
Objective To study whether the times of canalith repositioning procedures(CRPs), the caloric test, the residual dizziness (RD) after CRPs were related to the recurrence rate in idiopathic horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV). Method：Successful CRPs of HSC-BPPV patients in outpatient from January 2016 to January 2018 were enrolled. All patients were performed the Barbecue maneuver. According to the times of CRPs, they were divided into two groups: group A (＜3times) and group B (≥3times). According to the patients who had residual dizziness（RD）, they were divided into another two groups: group C (no RD), group D (with RD). All patients underwent caloric test. Result There was no significant difference in the recurrence rate between group A (20.9%) and group B (26.8%). The difference between group C (11.8%) and group D (32%) in recurrence rate was of statistical significance (p=0.033). Patients with residual dizziness after CRPs complicated with abnormal caloric test with the highest recurrence rate,66.7%). The recurrence rate was the lowest when patients with CRPs ＜ 3 times and no residual dizziness after CRPs (6.3%). Conclusion The recurrence rate of horizontal semicircular canal BPPV is not related to the times of CRPs. A strong correlation between RD and abnormal C-test is noted. Residual dizziness after CRPs with abnormal caloric test indicates the increased recurrence rate of the patients with horizontal semicircular canal BPPV.
