OBJECTIVES: Literature that discusses the benefits of cochlear implantation (CI) in children under the age of two is limited. Previous concerns about surgical risk have been raised and addressed; however, actual benefit in terms of outcomes needs to be clearly defined. This study evaluates outcomes of children implanted under the age of two and compares them to children implanted at a later age. METHODS: Data were reviewed from the MED-EL International Children's study database. Thirty-seven children enrolled in the study have received cochlear implants before the age of two. Outcomes were assessed using the LiP and MTP tests and the MAIS and MUSS questionnaires pre-operatively and then at initial fitting, 1, 3, 6 and 12 months after first fitting and then annually thereafter. RESULTS: Statistical analysis demonstrated that these children's scores improved significantly over time. Improvement was shown to occur at a quicker rate than for children implanted at an older age with the MTP and MUSS, but not with the LiP and the MAIS. Scores may be limited by sample size and the fact that children reached ceiling on some tests. CONCLUSIONS: Results suggest a distinct advantage early implantation may have for severe to profoundly hearing impaired children. This may be particularly the case for skills necessary for development of receptive and expressive language skills.
