Benign paroxysmal positional vertigo: a multi-center study

Abstract
Background
Benign paroxysmal positional vertigo (BPPV) is the most frequent vestibular disorder with significant morbidity, psychosocial impact, and medical costs. This multi-center study work aimed to review BPPV clinical features, treatment, and outcomes.

Methods
After a detailed history, clinical examination, audiological assessment, and position provocation tests to diagnose BPPV type, the suitable repositioning maneuver was done. BPPV was diagnosed according to the criteria developed for this study through piloting and validation in a specialized dizziness clinic. The main outcome measures were patient demographics, comorbidities, canal involvement, response to treatment, and incidence of recurrence.

Results
Within included 114 patients, the affected canal was 93% posterior semicircular canal, 3.5% horizontal semicircular canal, and 3.5% anterior semicircular canal. The response after repositioning maneuver was (86%) after one session and 100% after the second session.

Conclusion
Meticulous BBPV assessment with choosing appropriated provocation test help to diagnose and identify the type of BPPV and so applying appropriated suitable repositioning maneuver.
