Objectives/Hypothesis To evaluate the short‐term efficacy of the computer‐controlled canalith repositioning procedure (CRP) for treatment of posterior canal benign paroxysmal positional vertigo (BPPV) compared with the current standard CRP. Study Design Prospective case series. Methods One hundred thirty‐two patients diagnosed as having idiopathic posterior canal BPPV, with an age range of 28 to 86 years (mean 56 years), 47 men and 85 women, were treated with computer‐controlled CRP mimicking the Epley maneuver. Resolution of vertigo and nystagmus on the Dix‐Hallpike test at 1‐week follow‐up after treatment was the main outcome measure to assess the efficacy of treatment. Results At 1‐week follow‐up after treatment with computer‐controlled CRP, 108 (81.8%) of 132 patients had complete resolution of vertigo and nystagmus, nine (6.8%) had resolution of vertigo but presence of nystagmus, and 15 (11.4%) had provoked vertigo and nystagmus on the Dix‐Hallpike test. The 81.8% success rate was comparable to those who received current standard CRP treatment in randomized controlled trials at about 80%. No significant adverse effects or complications occurred in the patients treated with computer‐controlled CRP, aside from two patients (1.5%) with conversion into lateral canal BPPV. Conclusions Computer‐controlled CRP is effective for the treatment of posterior canal BPPV, with a success rate similar to those treated with the Epley maneuver, and is safe and easy to perform on patients.
