Objective:
Rehabilitation success in cochlear implant patients is influenced by many factors. Influence of different etiologies of deafness on rehabilitation outcome is assessed.
Study Design:
Retrospective survey of patients.
Setting:
University hospital. Secondary referral center.
Patients:
One hundred and sixty-three between 1996 and 2008 implanted children (0-18 years, mean 5.17 years).
Interventions:
Evaluation of patients' data: origin of deafness, hearing and speech test results. Access Data Base; Wilcoxon and t-test.
Results:
Mean 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.
Discussion:
Primary 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.
