Abstract
ObjectiveRehabilitation success in cochlear implant patients is influenced by many factors. Influence of different etiologies of deafness on rehabilitation outcome is assessed.MethodsStudy designRetrospective survey of patients.SettingUniversity hospital. Secondary referral center.PatientsOne hundred and sixty-three between 1996 and 2008 implanted children (0–18 years, mean 5.17 years).InterventionsEvaluation of patients’ data: origin of deafness, hearing and speech test results. Access Data Base; Wilcoxon and t-test.ResultsMean follow-up: 65.4 months. Etiology of deafness in children found in 104 cases: 69 (51.9%) suffered from hereditary hearing loss. All children showed improvement in their auditory performance, children with connexin-26 mutation performed significantly best, Usher and CHARGE-syndrome children significantly worst. Post-meningitic and post-septic children developed slower but reached same levels later.DiscussionPrimary cause of deafness, among other factors, has a considerable impact on outcome of rehabilitation. This offers possibilities to influence the outcome by etiology-adjusted therapy modules.
