&
Pages 21-26 | Published online: 11 Jul 2009
 

Abstract

Paroxysmal positional vertigo (PPV) is one of the most frequent types of true objective dizziness. Progress in the knowledge of the pathogenetic mechanisms of PPV and, still more, the excellent results obtained in the last 20 years with the liberatory or repositioning manoeuvres have created much enthusiasm for the possibilities of resolving this disease. Many factors, however, make it difficult to appraise the incidence, prevalence and spontaneous evolution of PPV in a vast sample of cases or in well determined territories. In any event it is evident that the natural course of PPV is not the same in all patients and it may be influenced by different factors.
