Benign paroxysmal positional vertigo (BPPV) is usually idiopathic, but in some cases, it arises after inner ear disease. We examined the cases with and without BPPV-like symptoms in sudden deafness (SD), Ménières disease (MD) and vestibular neuritis (VN). The equilibrium function tests (caloric test, VEMP and SVV) results were not different between the groups with or without BPPV-like symptoms, but hospitalization was needed more frequently in cases with BPPV-like symptoms. The posterior semicircular canal (PSC) is the most frequent focus of both idiopathic BPPV and BPPV-like symptoms after inner ear disease. The recovery period from vertigo was longer in the cases with BPPV-like symptoms. The effect of physical therapy for the PSC type was equally favorable in cases with idiopathic BPPV and those with inner ear disease associated with BPPV-like symptoms. For the lateral semicircular canal (LSC) type, the effect was less pronounced in cases with idiopathic BPPV. Occurrence of BPPV-like symptoms associated with inner ear disease is possibly caused by the canalolithiasis induced by utricular disturbances.
