目的 研究特发性水平半规管良性阵发性位置性眩晕(HSC-BPPV)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—2018年1月门诊手法复位成功的84例特发性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)和D组(残余眩晕)，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%)与B组(26.8%)的复发率无明显差异;C组(11.8%)与D组(32.0%)复发率差异具有统计学意义(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 HSC-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 the relationship between the times of canalith repositioning procedures (CRPs), caloric test (C-test), residual dizziness (RD) after CRPs and the recurrence rate in idiopathic horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV).Methods Eighty-four HSC-BPPV patients with successful CRPs of Barbecue maneuver in outpatient department from Jan 2016 to Jan 2018 were enrolled. According to the times of CRPs, they were divided into two groups: group A (<3 times) and group B (≥3 times). According to whether the patients had RD, they were divided into another two groups: group C (without RD) and group D (with RD). All patients underwent C-test.Results 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 (32.0%) in recurrence rate was of statistical significance (P=0.033). Patients with RD after CRPs had high rate of abnormal C-test, and those with RD complicated with abnormal C-test had the highest recurrence rate (66.7%). The recurrence rate was the lowest in patients without RD after CRPs < 3 times (6.3%).Conclusions The recurrence rate of HSC-BPPV is not related to the times of CRPs. A strong correlation between RD and abnormal C-test is noted. RD after CRPs with abnormal C-test indicates increased recurrence rate in patients with HSC-BPPV.
