Fibroma osificante juvenil trabecular mandibular: Presentación de un caso con reconstrucción inmediata mediante un injerto libre de la cresta ilíaca y costocondral

Abstract

Juvenile ossifying fibroma (JOF) is a benign fibro-osseous lesion with an aggressive biological behavior in most cases. The clinical course is fast, manifesting mainly as a facial asymmetry. Radiographically it presents as a well-defined, uni- or multi-locular radiolucent lesion with variable radiopaque areas. Treatment may vary depending on the clinical, imaging and histopathological specific pattern, but generally an aggressive treatment with resection is the most appropriate. We report a case of a child with an extensive trabecular JOF (TFOJ) of the mandible. We performed a complete resection of the lesion with a security margin and immediate reconstruction with a costochondral-iliac crest bone graft. Postoperative controls were performed for seven years, during which there were no signs of recurrence, demonstrating a successful functional and anesthetic reconstruction.
