Abstract
Canalolithiasis is potentially a primary mechanism of benign paroxysmal positional vertigo (BPPV) of lateral canal type. The authors designed a canalith repositioning procedure (CRP) for this type of BPPV. CRP was perfomed in 13 cases. The vertigenous symptom was alleviated in 76.9%, and the nystagmus disappeared or decreased in 84.6% of the total patients. The overall efficacy rate was 84.6%. CRP should be first attempted in cases of lateral canal type BPPV.
