title: Comprehension of language in congenitally deaf children with and without cochlear implants.
abstract: The consequences of profound early deafness on oral language in children are drastic. The modern cochlear implant (CI) has been shown to enhance speech production skills in prelingually deaf children. Many factors may contribute to a poor or an excellent outcome, making it difficult to compare groups of children wearing or not wearing cochlear implants. The present study compared receptive language levels in matched pairs of children from CI group and non-CI groups. The pre-op receptive language development curve suggest a possible growth over time with the maturation and the speech therapy. Comparison showed that the slope for post-op CI children to be greater than for non-CI children, and that this difference is statistically significant, and that the slope for CI children to be greater post- than pre-operatively. The main conclusion is that receptive language scores grow significantly higher over time after surgery in CI than in pair-matched non-CI children, despite better initial pure tone audiometric thresholds of the latter.
