Benign paroxysmal positional vertigo (BPPV) is usually idiopathic and characterized by transient position-induced nystagmus with vertigo. However, it is widely known that BPPV-like symptoms arise during the course of diseases such as Meniere’s disease, sudden deafness, and vestibular neuritis. We report three patients who developed sudden sensorineural hearing loss with BPPV-like symptoms in the same ear. Two patients showed vertigo characterized by the lateral semicircular canal (LSCC), the other patient showed vertigo characterized by a combination of the posterior semicircular canal (PSCC) and the LSCC. Two patients had canal paresis (CP), but did not have otolith dysfunction. The hearing level improved significantly in two patients. BPPV-like symptoms with sudden deafness is thought to be involved in canalithiasis, as physical therapy has been effective in some cases. We suppose that the BPPV-like symptoms arise from the falling of the otolith associated with inner ear dysfunction.
