title: [Long-term observation of sensorineural hearing-impaired children with hearing aids].
abstract: In the long-term observation (9-22 years) of 45 hearing-impaired children, using our own "Hearing Test Progress Table", 36(80.0%) showed fluctuation of the hearing threshold. Twenty-nine of the 36 patients had acute progression of hearing loss. Three peaks of onset of the acute loss were observed: at age 6, 10, 16 years in girls, 7, 11 and 16 years in boys. Twenty-three of the 45 (51.1%) have been able to maintain their good thresholds throughout these periods, with 14 cases of hearing loss restored by our successful treatment of acute sensorineural hearing losses (1-6 times). Twenty-two of the 45 children (48.9%) could not maintain their initial thresholds: gradual hearing deterioration in 7 of the 22, and acute hearing loss (1-10 times) in the remaining 15 cases. Although these 15 patients could not maintain their initial hearing thresholds until the end of the observation period, active treatments for their acute losses were successful in the early period, and almost all patients were able to maintain their initial hearing thresholds until graduation from elementary school. Our "Hearing Test Progress Table" is based on the results of pure tone audiometry for each frequency on every audiometry test. The management (including guidance and treatment) using the table is very effective.
