canalith-repositioning-procedureThe Canalith Repositioning Procedure is also known as the “Epley maneuver.” BPPV occurs as a result of displaced otoconia, which are small crystals of calcium carbonate (also referred to as “otoliths” or “canaliths”) that are normally attached to the otolithic membrane in the utricle of the inner ear. Because of trauma, infection, or even simple aging, canaliths can detach from the utricle and collect within the semicircular canals. Head movements shift the detached canaliths and stimulate sensitive nerve hairs to send false signals to the brain, causing dizziness and other symptoms. The goal of the canalith repositioning procedure (CRP), a form of vestibular rehabilitation therapy, is to move the displaced canaliths to stop these false signals and the debilitating symptoms they can cause.
