Summary
Introduction: The implantable prosthesis of osseous conduction (BAHA) is deemed to be an excellent option in the auditory rehabilitation of patients with conductive and mixed hearing loss, unilaterally or bilaterally, and unilateral sensorineural hearing loss. It has been a good advantage over the conservative bone conduction apparatus and those of individual sound-amplifier apparatus (ISAA), when their usage becomes unfeasible because of chronic otitis externa, which has a hard clinic control.
Objective: To introduce the first BAHA case performed in Brazil, as duly authorized by ANVISA (National Agency for Sanitary Surveillance), to rehabilitate the mixed hearing loss with occurrences of chronic otitis externa.
Method: 50-year-old female patient with right-ear moderate and left-ear severe hearing loss, bilateral tinnitus derived from otosclerosis, was submitted to 04 surgeries of stapedotomy and unable to use ISAA as a result of otorrhea and bilateral otalgia. The medical and audiological evaluation indicated the benefit of using BAHA. Having surgery been performed and BAHA implemented, the patient showed a significant improvement in audiometric thresholds, speech perception and distinction, as well as she declared to be extremely satisfied with the esthetic factor.
Final commentaries: BAHA surgical process is safe, simple and swift, thus providing excellent audiological results and a higher degree of satisfaction to patients.
Resumo
Introdução: A Prótese Implantável de Condução Óssea (BAHA) consiste em uma excelente opção na reabilitação auditiva de pacientes com perda auditiva condutiva e mista uni ou bilateral, e sensorioneural unilateral. Tem sido uma alternativa vantajosa sobre os aparelhos de condução óssea convencionais e os aparelhos de amplificação sonora individuais (AASI) quando o uso dos mesmos fica impossibilitado pela presença de otite externa crônica de difícil controle clínico.
Objetivo: Apresentar o primeiro caso de BAHA realizado no Brasil, após a autorização da ANVISA, para a reabilitação da perda auditiva mista com episódios de otite externa crônica.
Método: Paciente do sexo feminino, 50 anos, com perda auditiva de grau moderado à direita e severo à esquerda, zumbido bilateral, decorrente de otosclerose, submetida a quatro cirurgias de estapedotomia e com impossibilidade de uso de AASI devido a otorreia e otalgia bilateral. A avaliação médica e audiológica indicaram o benefício do BAHA. Realizada a cirurgia e implantação do sistema BAHA, a paciente apresentou melhora significativa nos limiares audiométricos, na percepção e discriminação da fala, além de relatar extrema satisfação relacionada ao fator estético.
Comentários Finais: O processo cirúrgico do BAHA é seguro, simples e rápido, proporcionando excelentes resultados audiológicos e alto grau de satisfação por parte dos pacientes.
