Abstract

Abstract : Introduction: While cochlear implants (CI) prior to 12 months of age have become common, the prevalence and impact of issues that either arise or were not evident prior to implantation is unknown. Methods: Retrospective chart review of children implanted under 12 months of age with minimum 3 years follow up. The children were divided into three groups: those with no identified additional disabilities, those with no known disabilities at time of implantation but diagnosed with additional disabilities following implantation, and those that had known anticipated additional disabilities at time of implantation. Results: 108 children under the age of 12 months were implanted at our Center between 2000 and 2013 with an average age of 9 months at time of implantation and n = 93 met inclusion criteria. In 79.6% (74/93) of children, there were no additional issues detected. In 11.8% (11/93), additional issues were known at the time of implantation while in 8.6% (8/93) of the children were diagnosed with additional issues that were not evident prior to implantation. The auditory and linguistic benefits vary commensurate with the severity of their disabilities. Those with anticipated issues preoperatively did not perform as well. Conclusions: Children implanted below one year of age but diagnosed with additional disabilities following implantation obtained substantial though varying degrees of benefit. In none of these cases would knowledge of the disability have altered the decision to offer early CI. It is important to address these potential issues when counseling families about outcomes.
