Immediate efficacy of the canalith repositioning procedure for the treatment of benign paroxysmal positional vertigo.
OBJECTIVE
To study the immediate efficacy of the canalith repositioning procedure (CRP) in the treatment of benign paroxysmal positional vertigo.


METHODS
Thirty-four patients with benign paroxysmal positional vertigo.


METHODS
Eighteen patients were treated with CRP (CRP group); 16 control patients did not receive CRP treatment (non-CRP group).


METHODS
We compared the success rates of the CRP and non-CRP groups. The treatment was considered successful if it prevented vertigo and dizziness. Patients were evaluated 3 times: immediately posttreatment (the day after the first visit), in the short term (1 wk after treatment), and in the midterm (1 mo after treatment).


RESULTS
Successful outcomes occurred in 12 patients (67%) from the CRP group and in 1 patient (6%) from the non-CRP group as immediate results (p < 0.001), 13 (72%) and 4 patients (25%) in the short term, respectively, (p = 0.007), and 16 (89%) and 14 patients (88%) in the midterm, respectively, (p > 0.05). Among patients in the CRP group who did not report immediate success, 1 patient (6%) reported success after 1 week (short term), and 4 patients (67%) had successful outcomes after 1 month (midterm).


CONCLUSIONS
The immediate efficacy of CRP supported the canalolithiasis theory. The prognosis of patients with immediate unsuccessful results with CRP was somewhat worse than that for patients without CRP treatment.
