RESUMO
UNLABELLED: According to data from the Brazilian Institute of Geography and Statistics, the elderly population grew 47.8% in the last decade in Brazil. A portion of this population has severe and/or profound hearing loss and do not benefit from conventional hearing aids. Thus, the use of cochlear implant is required. AIM: To analyze the benefits of cochlear implants in the elderly based on the comparison of primary auditory thresholds before and after the operation, discrimination of sentences in speech and in talking on the telephone. METHODOLOGY: Retrospective cohort study, analyzing medical records from patients aged over 60 years, users of cochlear implant for at least 1 year. RESULTS: Fourteen medical records were analyzed. Mean age of patients was 63.07 years. The mean pure tone thresholds between 500Hz, 1kHz, 2kHz and 4kHz before the implantation was 113dBHL. None of the patients, before operation, could discriminate sentences in open sets and only 3 scored 17% in closed sets sentence recognition. After one year of implantation, the mean sound field thresholds reached 34dBHL, and open set sentences recognition of 93.57%, while 71% of the patients had become able to have a conversation on the telephone. CONCLUSION: The elderly users of cochlear implant showed important outcomes, with significant improvement in understanding in the open set and in using the telephone.

Segundo dados do Instituto Brasileiro de Geografia e Estatística, a população de idosos cresceu 47,8 por cento na última década no Brasil. Parte desta população tem surdez severa a profunda, não se beneficiando com o uso dos aparelhos auditivos convencionais. Desse modo, torna-se necessária a indicação do implante coclear. OBJETIVO: Analisar os benefícios do implante coclear nos idosos com relação à audibilidade, ao reconhecimento de fala e ao uso do telefone. MATERIAL E MÉTODO: Estudo retrospectivo transversal por meio da análise de prontuários de pacientes com faixa etária acima de 60 anos usuários de implante coclear há pelo menos 1 ano. RESULTADOS: Foram analisados 14 prontuários. A média de idade dos pacientes foi de 63,07 anos. A média dos limiares tonais entre 500Hz,1kHz,2kHz e 4kHz antes da implantação foi de 113dBNA. Nenhum dos pacientes, antes de implantar, conseguia discriminar frases em contexto aberto e fechado, apenas 3 conseguiam fazê-lo com uma média de 17 por cento de acertos. Após um ano de uso de implante, a média dos limiares em campo passou a ser de 34 dBNA, a discriminação de frases em contexto aberto de 93,57 por cento e 71 por cento dos pacientes já conseguiam estabelecer uma conversa ao telefone. CONCLUSÃO: Os pacientes idosos usuários de implante coclear apresentaram ganhos auditivos relevantes, com melhora significativa da compreensão em contexto aberto e no uso de telefones.
