Objective Analyze the curative effect of manipulative reductionfor 223 patients with benign paroxysmal positional vertigo.Methods All 223 patients were diagnosed by Dix-Hallpike test and Roll test,posterior and anteriorsemicircular canal BPPV patients accepted Epley and Semont reset,lateral semicircular canal BPPV patiens received modified Barbecue rotation reset.Results It's showed that 152 cases(68.16%) were posterior semicircular canal BPPV,60 cases(26.91%) were lateral semicircular canal BPPV,1 case(0.45%) was anterior semicircular canal BPPV and 10 cases(4.48%) were mixed type.175 cases(78.48%) were treated successfully after reset once,33 cases(17.79%) were resetsuccessfully more than once,11 casespalindromia(4.93%) were observed after reset,3 cases(1.35%) present otolith shift after reduction and 1 case(0.45%) was failed in reset.The total efficiency was 99.55%.Conclusions It is safe and effective for the application of manipulative reductionin the treatment of BPPV.The key step for sccessful reset was judgethe semicircular canal which was affected and the otolith types accurately.
