Practical approach for lateral canal benign paroxysmal positional vertigo

Abstract

Benign paroxysmal positional vertigo (BPPV) of the lateral semicircular canal is a well-recognized condition, even though there are controversies about the repositioning maneuvers and their efficacy. In recent decades, several maneuvers have been proposed for treating both apogeotropic and geotropic variants of lateral canal BPPV. Our purpose is to discuss a practical approach to this pathology with the Zuma maneuver. In a single session, this maneuver may be useful to treat patients with canalithiasis of the ampullary and non-ampullary arms, and cupulolithiasis with the otoliths in the canal and utricular side of the lateral canal.
