BACKGROUND: Canalith repositioning procedure (CRP) has increasingly been utilized for the last 15 years for the treatment of benign paroxysmal positional vertigo (BPPV). We assess the short- and long-term efficacy of CRP on the treatment of patients with BPPV.
METHODS: Nine hundred sixty-five patients (481 men and 484 women, from 18 to 87 years of age) were enrolled in this prospective study during 1995-2010. Inclusion criteria were a patient history compatible with BPPV and a positive provocative maneuver (either Dix-Hallpike or Roll test). Reported duration of symptoms at the time of their first examination varied from 1 day to 18 months. Variants of the Epley and Barbeque maneuver were used for posterior and anterior canal involvement, and horizontal canal involvement, respectively. Short-term follow-up was obtained 48 h and 7 days after initial treatment, whereas long-term follow-up was obtained at repeated 6-month intervals.
RESULTS: Symptoms subsided immediately in 819 patients (85%) by the first CRP. Only 19 patients (2%) required CRP more than 3 times. Patients' mean follow-up was 74 months; symptom recurrence was noted in 139 patients. A statistically significantly higher recurrence rate was noted in elderly people or those with head trauma or a history of vestibular neuropathy (p<0.001).
CONCLUSIONS: This study provides class IV evidence that CRP remains an efficient and long-lasting noninvasive treatment for BPPV, especially for younger patients without a history of head trauma or vestibular neuropathy. Elderly people have a significantly higher recurrence rate requiring additional education to minimize potential morbidity of their falls.
