ABSTRACT
Objective To analyze the efficacy of epley maneuver associated with vertigo calming for treating posterior semicircular canal benign paroxysmal positional vertigo (PC-BPPV) in young.Methods Two hundred and fifty-eight cases(age was 18-50 years old) with PC-BPPV were randomly divided into maneuver group(86 cases),betahistine group(86 cases) and vertigo calming group(86 cases).The maneuver group was treated by epley maneuver associated with placebo,2 pills per time,3 times daily for one month and follow up one month.The betahistine group and vertigo calming group were treated by epley maneuver with betahistine(12 mg/ time,Tid) or vertigo calming(2 piles/time,Tid),the same dose,period of treatment and follow-up as maneuver group.Results After one time treatment,199 cases were cured in 258 patients,including 68 cases in maneuver group,66 cases in betahistine group,65 cases in vertigo calming group,and the difference between groups was not statistically significant(x2 =0.308,P＞0.05).After treatments and followed up for one month,72 cases were cured,3 cases were effective,11 cases were invalid in maneuver group;74 cases were cured,3 cases were effective,9 cases were invalid in betahistine group;81 cases were cured,4 cases were effective,1 cases were invalid in vertigo calming group.Efficient of betahistine group,maneuver group and vertigo calming group were 89.5％,87.2％ and 98.8％,and the difference between maneuver group and betahistine group was not statistically significant(x2=58.65,P＞0.05),the difference of vertigo calming group between with other groups was statistically significant(P＜0.05).Conclusion The effects of vertigo calming in addition to Epley maneuver is significantly better than both Epley maneuver and Epley maneuver combined with betahistine in young PC-BPPV,while the effects of Epley maneuver combined with betahistine isn't better than Epley maneuver.
