Benign paroxysmal positional vertigo secondary to vestibular neuritis

Abstract

The aim of this study was to present the demographic, pathogenetic and clinical features of benign paroxysmal positional vertigo (BPPV) secondary to vestibular neuritis (VN). The medical records of 22 patients, who presented with BPPV within 12 weeks after the onset of VN, were reviewed. Data of a complete otolaryngological, audiological, neurotologic and imaging evaluation were available for all patients. Two hundred and eighty-four patients with idiopathic BPPV were used as a control group. The patients with BPPV secondary to VN presented the following features, in which they differed from the patients with idiopathic BPPV: (1) a lower mean age; (2) involvement of the posterior semicircular canal; (3) presence of canal weakness; (4) more therapeutic sessions needed for cure and a higher rate of recurrence. It may be, thus, concluded that BPPV associated with VN differs from idiopathic BPPV in regard to several epidemiological and clinical features, it responds less effectively to treatment and may follow a protracted course, having a tendency for recurrence.
