By Mayo Clinic staffThe canalith repositioning procedure can help relieve benign paroxysmal vertigo (BPPV), a condition in which you have brief but intense episodes of dizziness that occur when you move your head. Vertigo usually comes from a problem with the part of the inner ear responsible for balance (vestibular labyrinth). BPPV occurs when tiny particles called canaliths in one part of your inner ear break loose and fall into the canals of your inner ear, causing vertigo.
The canalith repositioning procedure can move the canaliths to a part of your ear where they won't cause dizziness. Performed in your doctor's office, the canalith repositioning procedure consists of several simple head maneuvers.
