改良Epley手法复位联合倍他司汀治疗后半规管-良性发作性位置性眩晕

目的探讨改良Epley手法复位联合倍他司汀治疗后半规管-良性发作性位置性眩晕（Pc-BP-PV）的疗效。方法单侧PC—BPPV患者78例，随机分为手法复位组39例和联合治疗组39例；手法复位组采用改良Epley手法复位，联合治疗组采用改良Epley手法复位联合倍他司汀治疗，每次6mg，每天3次，连服用1个月。比较两组临床疗效。结果78例患者经过1次治疗，治愈56例，其中手法组28例，联合治疗组28例，两组差异无统计学意义（P〉0．05）。治疗1个月后，手法复位组治愈30例，有效3例，无效6例；联合治疗组治愈37例，有效1例，无效1例；联合治疗组治愈率94．9％，明显高于手法组的76．9％（X^2=4．3365，P〈0．05）。结论改良Epley手法复位联合倍他司汀治疗PC—BPPV疗效显著，值得推广应用。

Modified Epley maneuver associated with betahistine for treating posterior semicircular canal benign paroxysmal positional vertigo

Objective To analyze the efficacy of modified epley maneuver associated with betahistine for treating posterior semicircular canal benign paroxysmal positional vertigo （PC-BPPV）. Methods 78 cases with uni- lateral PC-BPPV were divided into complexed therapy group （39 cases） and control group （39 cases） randomly. The complexed therapy group was treated by modified epley maneuver associated with betahistine 6rag per time,3 times daily for successive 1 month, the control group was treated by modified epley maneuver only. Results 78 patients af- ter first treatment, 56 cases were cured, control group （28 patients）, complexed therapy group （28 cases）, no statisti- cally significant difference between the two groups. After 1 month of treatment, the control group were cured 30 cases, effective 3 cases,invalid 6 cases; the complexed therapy group were cured 37 cases, effective 1 case, invalid 1 case ; complexed therapy group, the cure rate was 94.9%, significantly higher than the 76.9% of control group （X2 = 4. 3365 ,P 〈 0.05 ）. Conclusion The modified epley maneuver associated with betahistine is effective to treat PC- BPPV,which is worth being promoted.
