Resumo

Introdução:
O mixoma odontogênico (MO) é um tumor benigno raro, porém localmente agressivo, com alta taxa de recorrência. Devido à sua baixa prevalência, o tratamento padronizado ainda é motivo de controvérsia.

Apresentação do caso:
Relatamos o caso de uma paciente de 21 anos atendida na Unidade de Cirurgia Bucomaxilofacial do Hospital Dr. Sótero del Río, diagnosticada com MO mandibular. A lesão se apresentou como uma radiolucidez unilocular bem delimitada com expansão da cortical lingual. A biópsia confirmou o diagnóstico de mixoma odontogênico.

Intervenção e resultados:
Em vez de realizar uma ressecção segmentar, optou-se por uma abordagem cirúrgica conservadora, com enucleação associada à osteotomia periférica. O acompanhamento radiológico aos 12 e 21 meses demonstrou completa regeneração óssea, sem evidências de recidiva.

Conclusão:
Este caso demonstra que o manejo conservador do MO pode proporcionar resultados favoráveis em longo prazo com menor morbidade, especialmente quando as características clínicas e de imagem indicam menor agressividade local.
