The aim of this study was to reveal clinical features of benign paroxysmal positional vertigo (BPPV) through comparing idiopathic BPPV and BPPV secondary to vestibular neuritis (VN). The clinical data of the 189 BPPV patients admitted to our tertiary care hospital including otolaryngological, audiological, vestibular, neurological, and radiological evaluations were reviewed. Patients diagnosed with idiopathic BPPV (n = 145) and BPPV secondary to VN (n = 44) were grouped as I and II, respectively. The clinical data of 2 groups were compared. The findings of the study showed that the patients with secondary BPPV due to VN are much younger, have symptoms of only posterior semicircular canal involvement, and require more treatments compared to patients with idiopathic BPPV. The clinical features of patients with BPPV secondary to VN and idiopathic BPPV differ on several aspects. More extensive studies are needed to investigate the underlying etiology in patients with BPPV encountered after VN.
