Paroxysmal positional vertigo.
Paroxysmal positional vertigo (PPV) is the peripheral vertiginous syndrome that is most frequently encountered in clinical practice. It is characterised by paroxysmal vertiginous attacks that are triggered by head movements and last no more than a few seconds, and is often accompanied by nausea and vomiting. The aim of this review is to provide a complete and updated description of the two principal manifestations of the syndrome: posterior semicircular canal (PSC-PPV) and horizontal semicircular canal PPV (HSC-PPV).
