Resumen

Introduction: Odontogenic myxoma is a rare benign tumor of mesenchymal origin with an aggressive behavior of slow and asymptomatic expansion. The treatment is surgical with various options from conservative to radical surgery. Objective: To present a case of odontogenic myxoma with extensive maxillary involvement with conservative surgical treatment. Clinical Case: A 14-year-old mixed-race male patient presented swelling with facial deformity. The tomography revealed a 10 x 10 cm isodense lesion with involvement of the orbital floor. The diagnosis of odontogenic myxoma was anatomopathological. Conservative surgery was performed: enucleation with peripheral osteotomy and extraction of involved teeth. Six months later, a maxillary obturator prosthesis was placed, and at 6 years of follow-up the patient was asymptomatic without tumor recurrence. Conclusions: Odontogenic myxoma is rare and requires surgical treatment; conservative treatment may be a surgical option which requires long-term periodic monitoring to assess recurrence.
