title: Cochlear implant candidacy and performance trends in children.
abstract: Data from Clarion cochlear implant pediatric clinical trials were examined retrospectively to uncover trends in candidacy and postimplant benefit over time. In particular, age at implantation, educational setting, and communication mode were examined with respect to speech perception performance after implantation. The results showed that 1) age at implantation is decreasing, 2) children in oral education programs obtain more benefit from a cochlear implant than children in total communication programs, 3) children who undergo implantation before 2 years of age show greater benefit than children who undergo implantation between 2 and 3 years of age, 4) more younger children are using oral communication than older children, and 5) more children with good auditory skills before implantation and more residual hearing are undergoing implantation. In sum, in the 11 years since implants have been available to children in the United States, candidacy criteria have evolved and benefit has increased as cochlear implant technology has advanced.
