Benign paroxysmal positional vertigo (BPPV) involves brief episodes of intense dizziness when you change the position of your head. Vertigo usually results from a problem with the nerves and structures of balance mechanism in your inner ear (vestibular labyrinth). BPPV occurs when particles break loose and fall into the wrong part of the canals of your inner ear, producing an episode of vertigo.
To help relieve BPPV, you may undergo the canalith repositioning procedure. Performed in your doctor's office, this procedure consists of several simple head maneuvers. The goal is to move particles from the fluid-filled semicircular chambers of your inner ear into a tiny bag-like structure (utricle) where these particles don't cause trouble or will be reabsorbed by the fluids of your body. Each maneuver is held for about 30 seconds.
