Clinical Efficacy of Epley Procedure for Treatment of Benign Paroxysmal Positional Vertigo of Posterior Semicircular Canal

Objective To assess the clinical efficacy of Epley procedure for treatment of benign paroxysmal positional vertigo of the posterior semicircular canal(PC-BPPV).Methods The patients with PC-BPPV enrolled in this study were randomly allocated to therapeutic group(Epley procedure in combination with postural restriction group) and control group(postural restriction alone group),the respective treatment were performed.The efficacy was evaluated by the standards of the following scales: cure,improvement,and no response.Results The cure rates in the therapeutic group were 82.76%,93.10%,100.00% on days 4,7 and 10,respectively,while the control group were 15.56%,24.44%,60.00% at the same time,respectively;The response rates in the therapeutic group were 96.55%,100.00%,100.00% on days 4,7 and 10,respectively,while the control group were 53.33%,68.89%,88.89% at the same time,respectively.There was significant difference between the two groups(P0.005).Conclusion Epley procedure in combination with postural restriction can obviously increase the curative rate and effective rate of PC-BPPV and is superior to postural restriction alone.
