Abstract


Os tumores ósseos odontogênicos e maxilofaciais incluem um grupo heterogêneo de lesões que variam de neoplasias benignas a malignas. O ameloblastoma é um tumor odontogênico benigno de origem epitelial, e representa a entidade mais comum desse grupo de lesões depois dos odontomas. Embora benigno é considerado agressivo, devido a capacidade de infiltração local e altas taxas de recidiva registradas. De diferente etiologia o mixoma odontogênico é uma neoplasia benigna rara de origem mesenquimal que afeta os ossos gnáticos, representando cerca de 5% dos tumores odontogênicos. Os tumores se apresentam radiograficamente como lesões radiolúcidas, uni ou multiloculares, com margens que variam de bem definidas à difusas. Clinicamente, a expansão óssea cortical e o deslocamento dentário são frequentemente observados. As metodologias propostas variam da tradicional cirurgia radical, a cirurgia conservadora e, recentemente terapias medicamentosas direcionadas especificamente as vias de sinalização envolvidas na patogênese tumoral. Cada metodologia apresenta vantagens e desvantagens, no entanto, tem sido observado uma tendência da literatura atual a utilizar métodos mais conservadores, associados a um acompanhamento periódico e a longo prazo. O objetivo do presente trabalho é relatar dois casos de um extenso ameloblastoma convencional em uma paciente jovem, e um mixoma odontogênico, tratado de maneira conservadora, e que tem demonstrado inicialmente um resultado adequado. Conclui-se que métodos alternativos e conservadores vem ganhando espaço no tratamento dessa patologia, os quais vem demonstrando resultados satisfatórios.
