RESUMO

INTRODUCTION. The oral language is the most effective form of communication in our society. Hearing is the primary method for the oral language development. Even though the Cochlear Implant (CI) does not replace the Cochlear Function, since the 90´s it has bringing results that are significant beneficial to the oral language development of children with prelingual severe to profound hearing loss. Current researches have been concerned identifying the factors that make some children users of IC with pre-lingual hearing loss to achieve better oral language performance than the others. Besides that, it is known that if the child is implanted soon and the time of use increases, the performance will improve. Few studies turn to the characterization of these children oral language, which is a deviant process in relation to normality, but still needs more research. OBJECTIVES: 1. Evaluate both the comprehensive and expressive language of children that have been Cochlear Implanted for 5 years. 2. Assess the relationship between the comprehensive and expressive language performances of this population. 3. Assess the relationship between the oral language performance and their speech perception. METHOD: 27 children with pre lingual hearing loss that have been implanted for 5 to 5 years and 11 months were evaluated by the Reynell Developmental Scales II ( RDLS) composed by the Comprehensive Scale (C) and Expression Scale (E). The quantitative description of the scores in the sections C and E was performed and the Pearson correlation coefficient between the median scores in the total scale of comprehension and expression of each individual was calculated. In addition, the Spearman correlation coefficient between the score in the C index and phonemes recognition, the score on section E and the score for phonemes recognition, RDLS total score index and phonemes recognition were also calculated. RESULTS: The median scores demonstrated that both on C and E there were greater difficulty with longer sentences, the grammatical meaning of words, words and sentences that were more independent of immediate context. The lexical meaning of words with more context were more straightforward. There were a positive statistically correlation between C and E. There was a significant statistically relationship between the rate of phonemes recognition of C, E and the total score of RDLS. CONCLUSIONS: Despite the established variability, the children that were implanted five years ago have found difficulties with the grammatical meaning of words, longer phrases, and words and phrases that do not depend on the immediate context. The oral language of children implanted five years ago is inferior if compared with children with the same chronological age. There was similarity between expression and comprehension, however, more studies are required to determine whether the superiority of one or other. The correlation between the speech perception and the language performance demonstrates the importance of hearing for oral language development
