“…CI indications have undergone evolutionary times and have depended on the technological development, on the improvement of surgical techniques and the training and qualification of interdisciplinary teams involved with all stages of the implantation process, which have allowed this technology to benefit people with varying degrees of hearing loss at different hearing deprivation times. 11 …”

“…Binaural hearing eliminates the shadow effect of the head, which is the obstruction of the head to the arrival of the sound stimulus when it is presented to one ear only; it provides the squelch effect, which is the ability of the auditory system to use the information from both ears when speech and noise are separated spatially and provides binaural summation as a result of central auditory processing to integrate and use the hearing of both ears. 11 …”

“…The CI is a biomedical, biocompatible and durable electronic device designed to perform the function of not present or damaged hair cells in the inner ear. It modifies the acoustic signal and provides electrical stimulation of the remaining fibers of the auditory nerve (1,2) , which can lead to practically normal auditory thresholds.…”

RESUMO Objetivo Caracterizar o desempenho auditivo e de linguagem oral em crianças implantadas com menos de dois anos de idade auditiva, por meio da Escala de Desenvolvimento de Audição e Linguagem (EDAL-1) e comparar os resultados aos de crianças ouvintes até 2 anos de idade. Métodos Estudo experimental de caráter descritivo. Participaram 141 crianças, divididas em dois grupos: grupo controle, com 92 normo-ouvintes, e grupo experimental, com 49 crianças surdas acompanhadas audiologicamente, durante os dois primeiros anos após a implantação. As normo-ouvintes passaram por avaliação auditiva e os pais responderam ao questionário EDAL-1. As crianças implantadas passaram por avaliação otorrinolaringológica e fonoaudiológica a cada três meses e os pais responderam ao EDAL-1. Resultados Nos dois grupos foram observadas respostas ascendentes, com melhora de acordo com o aumento da idade cronológica. Os resultados obtidos no grupo experimental foram estatisticamente piores que no grupo controle, porém, com tendência de crescimento. O EDAL-1 mostrou-se de fácil aplicação e permitiu o monitoramento do desempenho das crianças implantadas. Conclusão O desempenho auditivo e de linguagem oral em crianças surdas, usuárias de implante coclear, foi caracterizado pelo EDAL-1 e mostrou-se em crescimento, conforme o aumento do tempo de estimulação auditiva, fato também observado nas crianças ouvintes. Apesar disso, os resultados das crianças ouvintes foram melhores que os das crianças surdas implantadas.

“…Autores afirmam que o implante coclear bilateral no primeiro ano de uso possibilita a aquisição da linguagem oral de forma mais rápida quando comparado ao implante coclear unilateral. Isso ocorre porque o uso de implantes nas duas orelhas promove uma atividade cortical homogênea e organizada, refletindo em um desenvolvimento bilateral simétrico das vias auditivas (7).…”

Introduction:In order to have a better knowledge about the development of language skills in cochlear implant (CI) users it is necessary to evaluate the speech of these subjects using appropriate tests. The ABFW-Child Language Test is a tool that relates to various areas: phonology, vocabulary, fluency and pragmatics, and that can be used with cochlear implant users for the purposes of this study.Objective: To evaluate the vocabulary of children who are cochlear implant users. Method: This study evaluated 16 children who had CI surgery between 08 and 52 months of age. The subjects were divided in five groups according to the age at the time of the CI activation, as follows: Group 1: 3 children implanted unilaterally with hearing age between 12 and 23 months of age; Group 2: children implanted bilaterally with hearing age between 12 months and 23 months of age; Group 3: 3 children implanted unilaterally with hearing age between 24 and 35 months of age; Group 4: 3 children implanted unilaterally with hearing age between 36 and 47 months of age and Group 5: 4 children implanted unilaterally with hearing age between 48 years and 59 months of age. Results: In the vocabulary test, when comparing CI users considering the auditory brain development age and the chronological age of normal hearing children, all CI users performed better than the standards for normal hearing children. When comparing children with unilateral and bilateral CI, the bilateral cochlear implant users showed better results. When comparing test performance considering the chronological age, normal hearing children performed better, but the results were similar in CI users that systematically use the device and attend auditory rehabilitation sessions.Conclusion: The vocabulary of CI users in the present study was similar to normal hearing children's vocabulary. The vocabulary test proved to be an effective measure to observe the gaps in development and helped the conduction of speech therapy in order to achieve the full development of speech and language skills of these children.
