A Case of Sudden Deafness with Simultaneous Ipsilateral Positional Vertigo

Although some cases of benign positional vertigo are associated with a chronic ipsilateral sensorineural hearing loss, an association with simultaneous ipsilateral sudden deafness is rare. We report a 53-year old woman with sudden deaf-ness with simultaneous positional vertigo in the same ear characterized by benign paroxysmal positional vertigo of pos-terior semicircular canal type. After a modified Epley particle-repositioning maneuver, the patient's vertigo was resolved. Clinical and neuro-otologic evaluations suggested that the lesion responsible for this patient was probably located within inner ear rather than within the vestibulocochlear nerve.
