Differential Caloric Reactions In Deaf Children

Abstract

Material from 55 totally deaf children is presented. The vestibular function has been examined by means of a differential caloric test, using the Hallpike-Fitzgerald method. The results are compared with the etiology of the deafness and the changes found at tomography. The results appear to differ from earlier findings, as only a few reveal normal reactions. The discrepancies are discussed, and it is concluded that a rather close relation exists between hearing impairment and vestibular function.
