Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo (BPPV) is a disorder arising in the inner ear.

Its symptoms are repeated episodes of positional vertigo, that is, of a spinning sensation caused by changes in the position of the head. BPPV is the most common cause of the symptoms of vertigo. Within the labyrinth of the inner ear lie collections of calcium crystals known as otoconia or otoliths. In patients with BPPV, the otoconia are dislodged from their usual position within the utricleand migrate over time into one of the semicircular canals.
