[Psychogenic deafness in children--audiological characteristics].

During the period from 1980 to 1984, 50 cases (98 ears) of psychogenic deafness in children have been examined at the hearing clinic of the Department of Otolaryngology. All were school children aged from 6 to 15 years. They were classified into 3 groups (A, B, C) and their audiological, psychological, opthalmological findings and progress were reported. Cases of A group complained of deafness and consulted specialists of their own accords. Cases of B group have complained of symptom of ear, but consulted a doctor after screening audiometry and cases of C group have had no symptom of hearing trouble. Their audiological findings were the bilateral perceptive flat loss type, usually lying between 40 to 100 dB. Results of speech discrimination test were usually better than that of pure tones. A half of them revealed type V of Bekesy audiometry. There were unexplainable discrepancy between the threshold of pure tone audiometry and response threshold of ERA.
