手法复位不同类型良性发作性位置性眩晕的预后

Prognosis of different types of benign paroxysmal positional vertigo with repositioning procedure

目的探讨手法复位不同类型良性发作性位置性眩晕(BPPV)的预后。方法应用变位试验对62例BPPV患者进行分型、定位,并采用耳石复位技术给予复位治疗。结果耳石位于后半规管(PC)55例(88.7%),水平半规管(HC)14例(22.6%),前半规管1例(1.6%);单一半规管46例(74.2%),混合半规管13例(21.0%)。单一半规管复位后1 d及3 d治愈率明显高于混合半规管(均P<0.01),PC-BPPV复位后1 d及3 d治愈率明显高于HC-BPPV(均P<0.05);1周后治愈率差异均无统计学意义(均P>0.05)。结论后半规管型及单一半规管耳石BPPV患者复位治疗的早期疗效好于其他类型患者。

Objective To investigate the prognosis of different types of benign paroxysmal positional vertigo （BPPV） with repositioning procedure.Methods Applying displacement test to 62 BPPV patients for classifying and positioning,and adopting corresponding otolith replacing technology for repositioning procedure.Results The otolith was located in posterior semicircular canal （PC） in 55 cases （88.7%）,horizontal semicircular canal （HC） was in 14 cases （22.6%）,and former semicircular canal （AC） was in 1 case （1.6%）.Single semicircular canal with otolith was in 46 cases （74.2%）,and mixed semicircular canal was in 13 cases （21.0%）.The cure rates of single semicircular canal at 1 d and 3 d after treatment were significantly higher than those in mixed semicircular canal （all P 〈 0.01）,and the cure rates of PC at 1 d and 3 d after treatment were significantly higher than those in HC （all P 〈 0.01） ; and there were no statistical significance at 1 week after treatment （all P 〉 0.05）.Conclusion The early efficacy of PC and single semicircular canal BPPV is better than other types.
