Clinical Experience of bone-anchored hearing aid in a patient with Persistent Stapedial Artery

espanolWe present a case of an 8-year-old boy referred to our department due to speech and learning delays at school. Hearing investigations revealed severe mixed hearing loss on the left with normal hearing on the right. A CT scan was performed which revealed multiple middle ear malformations with Persistent Stapedial Artery (PSA) on the left. Although several therapeutic options had been considered, the patient was implanted with a bone-anchored hearing aid without surgical complications and with a subsequent hearing gain. To our knowledge, this is the first recorded case of bone-anchored hearing aid implantation in a pediatric patient with PSA portuguesApresentamos o caso de um menino de 8 anos de idade referenciado ao servico de otorrinolaringologia por atraso na linguagem e dificuldades de aprendizagem.
