[Diagnosis and therapeutic options in benign paroxysmal positional vertigo].
Benign paroxysmal positional vertigo (BPPV) is one of the most common and treatable causes of vertigo. We examined BPPV types and the effectiveness of physical therapy in each type. BPPV is caused by a utricular statoconium that blocks the semicircular canal. Statoconia can block any of the semicircular canals, but they generally affects the posterior canal. Diagnosis is based on a typical history and characteristic eye movements elicited by the Dix-Hallpike test. Treatment involves a physical maneuver designed to mobilize the free calcium particles from the semicircular canal to the utricle. Canalith repositioning is the mainstay of treatment. The maneuver is illustrated in detail and other forms of treatment and their indications are discussed.
