title: Speech perception and language criteria for paediatric cochlear implant candidature.
abstract: Existing criteria for cochlear implantation of children with impaired hearing aim to select children who will eventually achieve better speech perception scores with an implant than with a hearing aid. It is difficult to predict the eventual outcomes with hearing aid and implant because speech perception scores typically increase with age, and because the distribution of scores for implant and hearing aid users overlap considerably at all ages. This paper shows how speech perception scores can be combined with spoken language measures to arrive at an objective criterion for implant selection. The method also allows estimation of the likely increase in speech perception score within a few months of implantation and estimation of the probability that the child will perform better with the implant than the hearing aid. The criteria were based on data from 135 evaluations of 50 children using cochlear implants with monosyllabic words, open-set sentences, the Clinical Evaluation of Language Fundamentals, and the Peabody Picture Vocabulary Test. Data from 114 evaluations of 43 children using hearing aids were used to illustrate the sensitivity of the criteria.
