Attack of repeated vertigo in patients who have had previous profound to total hearing loss has been reported. The purpose of this study is to evaluate the effects of hearing level on caloric response. Authors performed bithermal air caloric tests in 57 patients(male 46, female 11) of sensorineural hearing impairment without vertigo and 20 normal persons(male 16, female 4). The results were as follows : 1) There was significant difference in positive ratio of canal paresis between hearing impaired patients(45.6%) and normal control groups(5.0%)(p<0.001). 2) There was significant correlation between positive ratio of canal paresis and degree of hearing impairment. Positive ratio of canal paresis was 76.9% in group of total deafness, 62.5% in moderated to severe and severe deafness, 25.0% in moderate deafness, 10.0% in mild deafness, and 5.0% in normal control group(p<0.05). 3) There was no relation between the canal paresis and the cause and duration of hearing impairment. Authors concluded that there is significant correlation between the degree of hearing impairment and the vestibular canal paresis.
