![]() ![]() ![]() There are two primary maneuvers: CRP (the Epley maneuver) and the Semont-Liberatory maneuver. However, in some instances additional treatment(s) may be necessary. The recurrence rate for BPPV after these maneuvers is low. Precautions are provided for the days immediately following the procedure in order to ensure that the canaliths don’t have the opportunity to return to their formerly problematic location in one of the semi-circular canals.ĬRP is very effective, with an approximate cure rate of 80%. CRP can be performed in the doctor’s office with medication such as diazepam to help block nausea during the procedure, which takes about 15 minutes to accomplish. These maneuvers involve a series of specifically patterned head and trunk movements performed by a trained professional who closely watches eye movements with each position change. Once in the utricle, the canaliths may re-adhere to the otolithic membrane, dissolve, be broken up, or move some place where they can’t cause symptoms. Through a series of head position changes, CRP moves the canaliths from the canal to the utricle. 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. Head movements shift the detached canaliths and stimulate sensitive nerve hairs to send false signals to the brain, causing dizziness and other symptoms. Because of trauma, infection, or even simple aging, canaliths can detach from the utricle and collect within the semicircular canals. The Canalith Repositioning Procedure is also known as the “Epley maneuver.”īPPV (Benign Paroxysmal Positional Vertigo) 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. ![]()
