Benign paroxysmal positional vertigo is a self-limiting peripheral vestibular disease, classified as primary: the cause is currently unknown; secondary: secondary to trauma, ear disorders and other systemic diseases. The pathogenesis is the detachment of otoliths from the otolith membrane of the ellipsoidal sac into the semicircular canal. The so-called benign is treatable and self-healing. Paroxysmal and positional means that the episodes of vertigo are brief and occur when the head moves to a specific position or a change in position induces a brief vertigo, which appears as a spinning, with nausea and vomiting, and the episodes of dizziness are brief, a few seconds or ten seconds or so. Treatment is based on repositioning therapy. The prognosis of this disease is good.
