Differential vestibular dysfunction in sudden unilateral hearing loss

Abstract

Auditory and vestibular function was examined in 29 patients with unilateral sensorineural hearing loss to identify characteristic vestibulocochlear lesion patterns. In 45%, a vestibular lesion was found, of which 53% had a combined impairment of the cochlea and the ipsilateral posterior semicircular canal, possibly reflecting vascular disease in the common cochlear artery.
