説明

We studied 49 cases of nonorganic hearing loss seen in the last 19 years at Yamagata University Hospital. More women (71%) were affected than men (29%). We found that the incidence peaked at from 6 to 11 years of age. In most cases, pure tone audiography showed moderate, flat sensorineural hearing loss. ABR and AMFR were useful in diagnosing nonorganic hearing loss, and Bekesy audiography was used for screening nonorganic hearing loss. We divided subjects into a screening group (SG) consisting of cases found by audiography in a school hearing test and a patient group (PG) consisting of those visiting our clinic reporting hearing problems.The SG accounted for 25 (51%) of 49 cases and the PG for 23 (47%). No significant difference was seen hearing impairment prognosis between groups. In the SG, 72% either reported or were conscious of hearing impairment. Psychological problems related to hearing loss were found both groups. Based upon these results, we concluded that SG should be followed up as carefully as PG.
