Benign paroxysmal positional vertigo recurrence and persistence

SummaryBenign paroxysmal positional vertigo (BPPV) is one of the most common vestibular disorders.AimTo study the recurrence and persistence of BPPV in patients treated with canalith repositioning maneuvers (CRM) during the period of one year.Study designlongitudinal contemporary cohort series.Materials and MethodsOne hundred patients with BPPV were followed up during 12 months after a treatment with CRM. Patients were classified according to disease evolution. Aquatic physiotherapy for vestibular rehabilitation (APVR) protocol was applied in cases of persistent BPPV.ResultsAfter CRM, 96% of the patients were free from BPPV's typical nystagmus and dizziness. During the follow up period of 1 year, 26 patients returned with typical BPPV nystagmus and vertigo. Nystagmus and vertigo were persistent in 4% of the patients. Persistent BPPV presented improvement when submitted to APVR. Conclusion: During the period of one year, BPPV was not recurrent in 70% of the patients, recurrent in 26% and persistent in 4%.
