良性阵发性位置性眩晕的自我治疗

目的比较改良的Epley耳石复位法（MEP）和改良的Semont耳石复位法（MSM）用于后半规管良性阵发性位置性眩晕（PC-BPPV）自我治疗的疗效。方法对2001年7月至2003年6月间的70例PC-BPPV患者分别使用MEP和MSM法进行自身治疗，1周后比较两组缓解率和治疗的副作用。结果MEP组中95％（n=37）患者完全缓解，而MSM组仅为58％（n=33，P〈0．001）。MSM组中，治疗的失败与动作执行的不准确密切相关。两组治疗有关的副作用差异无统计学意义。结论MEP比MSM能更有效的缓解PC-BPPV，MEP应为患者自身治疗的首选方法。

Self-treatment on benign paroxysmal positional vertigo

Objective To compare the efficacy of a self-applied modified Semont maneuver(MSM) with self-treatment using a modified Epley procedure(MEP) in patients with posterior canal benign paroxysmal positional vertigo(PC-BPPV).Methods All 70 patients with PC-BPPV were treated respctively by using MEP and MSM between July 2001 and June 2003,remission rate and treatment-related side effects were compared at the end of 1 week.Results Remission rate was 95% in the MEP group(n=37) vs 58% in the MSM group(n=33,P<0.001).Treatment failure was related to the incorrect performance of the maneuver in the MSM group,whereas treatment-related side effects did not show difference significantly between the groups.Conclusion MEP is more effective than the MSM in relieving BPPV,that MEP might be recommended as a first-line self-treatment approach.
