We have experienced 6 patients with the psychogenic hearing impairment in the past 6 months. They were all female and their age ranged from 11 to 13 years. Hearing impairment was bilateral in 5 patients and was unilateral in one. To establish the diagnosis, standard audiometry, speech audiometry Bekesy audiometry, Evoked Response Audiometry (Auditory Brainstem Response and Slow Vertex Response), stapedius reflex test, and tympanometry were performed. The visual field test was also examined and the personality of the patients was tested using Yatabe-Guilford test. The pure tone test revealed that the degree of hearing loss ranged from 40 dB to out of scale. The degree of hearing loss obtained by the speech audiometry was better than that was obtained by the pure tone test. Bekesy audiometry in 11 ears showed type V in 5 and type I in 6. The tympanogram, ERA (ABR and SVR), stapedius reflex were normal in all patients. In two patients, the defect of the visual field was observed. The results of the tests to study the personality of the patients revealed various types of abnormalities. This abnormalities were thought to be the intrinsic factors in this disease. In 5 patients, we found the extrinsic factors in their daily lives. The prognosis of 5 out of the 6 patients was good, but in 1 patient, whose charactor showed to be in a high grade neurotic state, the hearing loss was not changed. We treated her with the co-operation of a psychiatrist.
