Abstract

The benign paroxysmal positional vertigo (BPPV) is a vestibular disorder cause of vertigo. The BPPV may be corrected mechanically by repositioning maneuvers but even after successful maneuvers, some patients report residual dizziness for a certain period afterward. Early recognition and treatment might decrease the incidence of residual dizziness in patients with BPPV, especially in those patients with psychiatric comorbidities and in the elderly, lowering the risk of falling. Many pathogenetic hypotheses for residual dizziness are under debate. The purpose of this review was to identify, evaluate and review recent researches about possible causal factors involved in residual dizziness and the implications on clinical practice. A literature search was performed using different databases such as Pubmed and Scopus. The following search terms were used: residual dizziness, otolithic membrane and BPPV. The search found a total of 1192 titles, which were reduced to 963 after a procedure of de-duplication of the found titles. The research was then restricted to an interval of time comprised between 2000 and 2016 for a total of 800 titles. Among these titles, only those including the terms benign paroxysmal positional vertigo were considered eligible for this review. Only publications in English language were taken into consideration and we excluded those with not available abstract. Finally, 90 abstracts were obtained and critically evaluated by two different Authors, and additional studies were identified by hand searching from the references of artiche of interest. Only 53 were included in this work.
