Benign paroxysmal positional vertigo.
Benign paroxysmal positional vertigo is a disorder of the peripheral vestibular system characterized by brief episodes of vertigo precipitated by head movements in certain planes. It is one of the most common causes of vertigo. Displaced otolithic debris in the posterior semicircular canal is the proposed mechanism of this disorder and explains the success of repositioning procedures in treating these patients. The pathophysiology, diagnosis, and treatment options are discussed.
