Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV

Brazilian Journal of Otorhinolaryngology, 2022
Introduction: The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different ...
