Abstract
A case was presented to illustrate the use of hypnosis in otology for obtaining precise information relative to diagnosis when such information had been impossible to obtain with standard, as well as with special audiological tests. In this case it appeared imperative to determine threshold sensitivity for pure tones in view of progressive familial deafness. The results point up the fact that hypnosis can be utilized diagnostically in an otological clinic, and that serious consideration should be given to appropriate training of staff members in its use.
