Benign paroxysmal positional vertigo (BPPV) occurs as a result of displaced otoconia, which are small crystals of calcium carbonate normally found in the utricle of the inner ear. As a result of trauma, infection, or even simply due to the aging process, these crystals can detach from the utricle and migrate into the semicircular canals of the inner ear, causing patients to experience brief episodes of dizziness or vertigo with head movement. The goal of the CRM is to reposition the crystals back to the utricle through a series of specific and timed head positions or maneuvers.
