[Benign paroxysmal positional vertigo: diagnostic and therapeutic maneuvers].

Benign paroxysmal positional vertigo (BPPV) is a very frequent cause of vertigo. BPPV occurs when there is a pathological presence of otolith debris in the semicircular canals. The history of BPPV is often typical, with recurrent episodes of vertigo lasting less than one minute, triggered by head movements, without other neurological signs. The characteristics of the nystagmus observed during the diagnostic maneuvers of Hallpike and Supine Head Roll test allow the identification of the affected semicircular canal and the choice of the appropriate therapeutic maneuver, which in most cases will lead to recovery. This article presents the diagnostic and therapeutic maneuvers.
