A canalith repositioning procedure can help relieve benign paroxysmal positional vertigo (BPPV), a condition which causes brief but intense episodes of dizziness that occur when moving one’s head. Vertigo usually comes from a problem with the part of the inner ear responsible for balance. BPPV occurs when tiny particles called otoconia in one part of the inner ear break loose and fall into the canals of the inner ear.
Canalith repositioning moves the otoconia to a part of the ear where they won’t cause dizziness.
The canalith repositioning procedure involves holding four positions for about 30 to 45 seconds each. Typically, patients remain in each position an extra 20 seconds after symptoms have stopped. The procedure may be repeated three or more times within a treatment session.
Depending on the physician’s preferences, the patient may wear an infrared imaging device over his or her eyes. This device helps the health provider examine the eyes during each maneuver.

Anyone with BBPV who can go through the procedure safely may benefit from it. If BBPV returns after CRP, the procedure can be used again to treat recurrences.
