Objective: The purpose of this study was to assess the impact of cochlear implantation (CI) on health-related quality of life (HRQOL), to correlate the results with audiologic performance, and to analyze the influence of variables that possibly affect the CI outcome.
Study design: A retrospective study.
Subjects and methods: Fifty-six adult CI users were evaluated by two HRQOL-questionnaires (the Nijmegen Cochlear Implant Questionnaire [NCIQ] and the Medical Outcome Study Short-Form 36 [SF-36]) and speech-perception tests (Freiburger monosyllable and Hochmair, Schulz, Moser (HSM) sentence test).
Results: The NCIQ showed significant improvements in the total score and in all subdomains after CI. The NCIQ total score and the advanced sound-perception and speech-production score correlated significantly with speech test results. Significant inverse relationships were noted between speech test results and duration of deafness. Significant associations were found between time since CI, NCIQ total score, and speech test results.
Conclusion: The NCIQ was able to detect significant effects of CI on HRQOL and correlated with audiologic measures, supporting its use as a measurement tool in CI.
