Objective:To evaluate the influence of an additional roll test on the repositioning procedure by SRM-vertigo diagnosis system for horizontal canal benign paroxysmal positional vertigo（HC-BPPV）. Methods:A total of 713 patients diagnosed with HC-BPPV in Department of Otolaryngology Head and Neck Surgery，the First Affiliated Hospital of Xi'an Jiaotong University from Jan 2020 to Feb 2022 were enrolled. The patients were divided into two groups by hospital card numbers, in which the number is odd were considered as group A, and the number is even were considered as group B. The group A underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, while the group B first performed an additional roll test and then underwent two circles of Barbecue repositioning procedure by SRM-vertigo diagnosis system, to observe the cure rate and compare influence of HC-BPPV by an additional roll test. The quality of life and sleep of patients before and one-month after the treatment were assessed by the dizziness handicap inventory（DHI） and the pittsburgh sleep quality（PSQI）. Results:The cure rate of group A was 63.21%, and the cure rate of group B was 87.68%，the difference between the two groups was statistically significant（P<0.05）; The DHI score of patients after the repositioning was significantly lower than that before the repositioning（P<0.05）. The PSQI score after the repositioning was significantly lower than that before the repositioning（P<0.05）. The DHI and the PSQI scores after the repositioning were significantly lower than that before the repositioning, with a statistically significant difference （P< 0.05）. The total score of DHI in group B after treatment was lower than that in group A, with a statistically significant difference（P<0.05）. The total score of PSQI in group B after treatment was lower than that in group A, with non-statistically significant difference （P< 0.05）. Conclusion:An additional roll test before the repositioning procedure by SRM-vertigo diagnosis system can significantly improve the cure rate of HC-BPPV, relieve anxiety, and improve the quality of life.
目的：探讨SRM眩晕诊疗系统中增加滚转试验次数对水平半规管良性阵发性位置性眩晕（HC-BPPV）疗效的影响。 方法：选取2020年1月-2022年2月在西安交通大学第一附属医院耳鼻咽喉头颈外科就诊，且行手法传统滚转试验诊断为HC-BPPV管石症的患者713例，按就诊卡单双号分为2组，A组行眩晕诊疗系统Barbecue复位2圈，B组在眩晕诊疗系统先行1次滚转试验后再行Barbecue复位2圈，观察2组的痊愈率，比较增加滚转试验是否对HC-BPPV的疗效有所影响。采用眩晕障碍量表（DHI）和匹兹堡睡眠质量指数量表（PSQI）对患者治疗前及治疗后1个月的生活质量和睡眠情况进行评价。 结果：A组痊愈率63.21%，B组痊愈率87.68%，2组差异有统计学意义（P<0.05）；患者复位治疗后较复位前DHI、PSQI评分均明显下降，差异均有统计学意义（P<0.05）。B组治疗后的DHI总分小于A组的总分，差异有统计学意义（P<0.05）。B 组治疗后的 PSQI 总分小于 A 组的评分，差异无统计学意义（P > 0.05）。 结论：SRM眩晕诊疗系统复位前增加1次滚转试验可显著提高HC-BPPV复位的痊愈率，缓解焦虑情绪，从而改善患者生活质量。.
