颗粒复位法治疗后半规管良性阵发位置性眩晕

目的 评价颗粒复位法治疗良性阵发性位置性眩晕的效果。方法 对１９９６年７月－１９９８年６月间治疗的３１一半规管性良性性位置性眩晕患者进行回顾分析。地规管耳右症假说，患者接受１次颗粒复位法治疗。治疗结束２周后复查并评价疗效。结果 ２１例患者的眩晕和眼一立刻或在１－２周内逐渐消失。６例改善，４例无效。总有效率８７．１％。结论 颗粒复位法对大多数良性阵发性位置性眩晕患者有效，推荐作为治疗该的首选方法。

Particle repositioning maneuver for benign paroxysmal positional vertigo of posterior semicircular canal]

OBJECTIVE: To determine the effectiveness of particle repositioning maneuver (PRM) for the treatment of benign paroxysmal positional vertigo (BPPV). METHODS: Thirty one patients with BPPV of the posterior semicircular canal treated between July 1996 and June 1998 were retrospectively analyzed. Patients received a single treatment of PRM based on the hypothesis that the vertigo and nystagmus of BPPV were due to debris floating in the long arm of the posterior canal (canalithiasis). Treatment outcome was classified as cure (asymptomatic), improvement reduction of symptoms > 50%, or no change. RESULTS: After a single treatment of PRM, complete remission of vertigo and nystagmus were found in 67.7% of the patients and improvement of the symptoms was found in 19.4% of the patients. The total improvement rate was 87.1%. CONCLUSION: The particle repositioning maneuver was effective for most of the patients with benign paroxysmal positional vertigo and can be recommended as the first-line treatment modality.
