Abstract
Benign paroxysmal positional vertigo (BPPV) is the most common and most treatable cause of vertigo. In most cases, a simple maneuver that takes less than a few minutes to do resolves the problem. BPPV is caused by misplaced calcium carbonate crystals (otoconia) in the semicircular canal of the inner ear that have broken free from the utricle. When these crystals break free, they either remain loose in one of three different semicircular canals or attach to the hair cells within a canal. Several different types of treatment maneuvers have been described. The maneuver to use varies according to the semicircular canal involved and whether the crystals are loose or attached to the hair cells.

Study of 33 patients with posterior canal benign paroxysmal positional vertigo that documented degree of imbalance on dynamic posturography. This study eliminated all cases of head trauma and vestibular loss (negative caloric or rotary chair). After canalith repositioning maneuver, balance returned to normal in one third of the patients and recovery occurred primarily in younger patients.

Interesting study that shows individual otoconia dissolve in endolymph fluid after 72 hours. May explain spontaneous recover in some patients with benign paroxysmal positional vertigo (BPPV). May also explain why repetitive exercises (Brandt-Daroff) can resolve BPPV.
