O BAHA (Bone Anchored Hearing Aid - prótese auditiva ancorada no osso) é utilizado em malformações do ouvido externo e médio, otorreia crónica, doença ossicular inoperável e como alternativa à prótese auditiva convencional por inadaptação/ impossibilidade. Este artigo descreve a experiência de colocação de BAHA no Hospital Maria Pia – Centro Hospitalar do Porto na última década, por estudo retrospectivo de 47 pacientes. O ganho audiométrico médio foi de 33,9 dB em relação aos valores base e de 14,4 dB em relação ao uso de próteses auditivas convencionais, com limiar auditivo médio com BAHA de 17,8 dB. Não houve qualquer complicação intra-operatória. No pós-operatório, quatro casos exigiram cirurgia para revisão da pele, em dois casos não houve integração óssea do implante e em três casos houve extrusão do implante por traumatismo directo. Este estudo conclui que os BAHA são um método eficaz e seguro de aparelhamento auditivo em crianças.Referências
