[Efficacy of different treatment on residual symptoms aftercanalith repositioning procedure in patients withbenign paroxysmal positional vertigo].

To assess which methods are effective for residual symptoms after canalith repositioning procedure in patients with benign paroxysmal positional vertigo(BPPV) then guide the clinical treatment.A total of 93 cases who were diagnosed with BPPV,then after the canalith repositioning procedure,which still have residual symptoms were enrolled in our study.They were randomized into three groups,The control group(A),The drug group(Ginkgo Leaves Soft-gel Capsule and Qiangli Dingxuan tablets)(B),The vestibular rehabilitation gymnastics group(C).Then compare the efficacy of different treatment.In the follow-up of 30 days,the number of DHI scores decline of group A is significantly lower than that of group B(<0.05) and C(<0.05),making statistical significance.The residual symptom duration of group A is significantly longer than that of group B(<0.05) and C(<0.05),making statistical significance.There is no significant statistical difference in comparing the number of DHI scores decline in the follow-up of 30 days,and the residual symptom duration of B and C(>0.05).The drugs for improve the microcirculation and vestibular rehabilitation gymnastics can reduce the duration of residual symptoms.
