Evolução da perda auditiva no decorrer do envelhecimento

Abstract

A perda auditiva associada ao envelhecimento refere-se à soma de perdas auditivas resultantes da degeneração fisiológica causada por exposição ao ruído, agentes ototóxicos e prejuízos causados por desordens e tratamentos médicos. Afeta cerca de 60% de todas as pessoas com idade acima de 65 anos. OBJETIVO: Verificar a degeneração do sistema auditivo no decorrer da idade através de medidas supraliminares e de sensibilidade auditiva. MATERIAL E MÉTODO: Estudo de coorte contemporânea com corte transversal. Foram avaliados 211 idosos, com idade média de 75,24 anos, sendo 61 do sexo masculino e 150 do sexo feminino. Os indivíduos foram submetidos a uma anamnese e à avaliação audiológica básica e divididos em quatro grupos, de acordo com a faixa etária. RESULTADOS: Declínio significativo do limiar nas 4 faixas etárias estabelecidas, diminuição do índice percentual de reconhecimento de fala, diferença significante com relação ao gênero. CONCLUSÃO: Com o avanço da idade, ocorreu um aumento gradual no grau da perda auditiva, os homens apresentaram limiares mais rebaixados na freqüência de 4000Hz em comparação com as mulheres e na inteligibilidade de fala observou-se decréscimo gradativo com o aumento da idade.
