Ameloblastoma em maxila: sugestão de abordagem cirúrgica

View through CrossRef
Introdução: O ameloblastoma é um tumor benigno, localmente invasivo, originário do epitélio odontogênico e é a neoplasia odontogênica mais comum. Apresentam crescimento lento e sua ocorrência na maxila é pouco frequente. Objetivo: Discutir os métodos de tratamento para os ameloblastomas em maxila e demonstrar a utilidade da osteotomia Le Fort I na abordagem destas lesões. Material e Método: Estudo descritivo de relato de caso. Resultados: Observou-se a erradicação da lesão com uma abordagem de baixa morbidade e que permitiu bom resultado estético e funcional. Conclusão: A ressecção é o método mais indicado para tratamento dos ameloblastomas sólidos, e a sua realização utilizando a osteotomia Le Fort I podem trazer vantagens tanto no trans quanto no pós-operatório.Descritores: Ameloblastoma; Maxila; Osteotomia de Le Fort.ReferênciasKreppel M, Zöller J.
