360°滚转复位法治疗良性阵发性位置性眩晕

目的明确在后半规管平面360°旋转患者对治疗典型的后半规管良性阵发性位置性眩晕是否有效。方法回顾分析了46例后半规管良性阵发性位置性眩晕患者，其中25例采用三维滚轮360°滚转复位法进行复位治疗，21例采用Epley手法复位治疗，对其疗效进行比较。结果采用三维滚轮360。滚转复位法治疗的患者中第一次治疗后有23例患者（92％）治愈，2例患者经过第二次治疗治愈；采用Epley手法复位的患者中第一次治疗后有19例患者（91.5％）治愈，2例患者经过第二次治疗治愈。应用X^2检验（α=0.05，X^2=0.1173，P=0.7319）二者的差异没有统计学意义。结论三维滚轮360°滚转复位法能有效的治疗后半规管良性阵发性位置性眩晕，其成功率及效果与Epley法一致，且操作简便、舒适度优于传统方法。

360-degree maneuver for benign paroxysmal positional vertigo

Objective To determine whether 360 degree rotation in the plane of the posterior semicircular canal is effective in treating classic benign paroxysmal positional vertigo.Methods Forty six cases of benign paroxysmal positional vertigo in the plane of the posterior semicircular canal were reviewed.Of these cases,25 were treated with the 360-degree maneuver,and 21 with the Epley maneuver.The treatment outcomes of the two maneuvem were compared.Results Most patients(23 in the 360-degree maneuver group and 19 in the Epley maneuver group)underwent 1 session of treatment,and only a few(2 in the 360-degree maneuver group and 2 in the Epley maneuver group)received 2 sessions of treatment.The treatment outcomes were not statistically difierent between the two groups as demonstrated by chi-square (x~2)test(,x~2=0.1173,P=0.7319).Conclusion The 360-degree maneuver can be effectively used in benign paroxysmal positional vertigo in the plane of the posterior semicircular canal.Its success rate is comparable to that of the standard Epley maneuver,but it is easier to tolerate by patients compared to the latter.
