Efficacy of computer-controlled repositioning procedure for benign paroxysmal positional vertigo.

Abstract

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.
