Immediate free flap mandibular reconstruction in osteosarcoma of the mandible in childhood.

Mandibular osteogenic sarcoma (OS) is a very rare entity in childhood. Adequate surgical rejection with a wide margin of normal tissue is the mainstay of treatment of this site, while the role of adjuvant chemotherapy remains uncertain. A case is presented of a 15 1/2-year-old male with a huge OS of the mandible. The boy underwent surgical resection of the mandible with immediate fibula free flap reconstruction and is alive and free of disease 6 1/2 years following unitial diagnosis. This case suggests that immediate bone reconstitution with vascularized grafts have good functional and morphological results for osteosarcoma of the lower jaw.
