Objective:To evaluate the effect of body mass index （BMI） on efficacy of the repositioning procedure for horizontal canal benign paroxysmal positional vertigo （HC-BPPV）. Methods:A total of 172 patients diagnosed with HC-BPPV in the First Affiliated Hospital of Xi'an Jiaotong University School of Medicine from Jan 2021 to Oct 2021 were enrolled. The patients were divided into low BMI group（BMI<24 kg/m² ） and high BMI group（BMI≥24 kg/m²）. The two groups underwent manual repositioning procedure and vertigo treatment system procedure by Barbecue method according to their orders of visits. After two circles of repositioning, the influencing factors of repositioning were analyzed according to efficiency. Results:The effective rate of manual repositioning in HC-BPPV patients was 33.64%, and the effective rate of vertigo treatment system was 63.08%,the effective rate of vertigo treatment system repositioning was higher than that of manual repositioning （P<0.05）. The effective rate of manual repositioning in the low BMI group （58.70%） was higher than that in the high BMI group （14.75%）, P<0.05. The effective rate of vertigo treatment system repositioning was higher in the low BMI group （75.00%） than that in the high BMI group （54.05%）, but there was no statistically significant difference between the two BMI groups （P>0.05）. Logistic regression analysis suggested that BMI was the influencing factor of HC-BPPV repositioning efficacy （P<0.05）. Conclusion:BMI can affect the efficacy of HC-BPPV manual repositioning. Vertigo treatment system for HC-BPPV reduction is better than manual reduction, and the efficacy is not affected by BMI.

目的：探讨体重指数（BMI）对水平半规管良性阵发性位置性眩晕（HC-BPPV）患者复位疗效的影响。 方法：选取2021年1月—2021年10月在西安交通大学第一附属医院确诊为HC-BPPV的患者172例，根据BMI分为低BMI组（BMI<24 kg/m²）和高BMI组（BMI≥24 kg/m²）。两组根据就诊顺序分别行手法复位和眩晕诊疗系统Barbecue法复位，在完成2圈复位后，根据有效率分析HC-BPPV复位的影响因素。 结果：HC-BPPV患者手法复位的总有效率为33.64%，眩晕诊疗系统的总有效率为63.08%，眩晕诊疗系统复位的总有效率高于手法复位（P<0.05）。低BMI组行手法复位的有效率（58.70%）高于高BMI组（14.75%），P<0.05；低BMI组行诊疗系统复位的有效率（75.00%）与高BMI组（54.05%）比较差异无统计学意义（P>0.05）。logistic回归分析提示BMI是HC-BPPV复位疗效的影响因素（P<0.05）。 结论：BMI会影响HC-BPPV手法复位的疗效。眩晕诊疗系统对于HC-BPPV复位的疗效优于手法复位，且疗效不受BMI影响。.
