title: Combined use of an orbital osteotomy and living bone graft in the treatment of huge ossifying tumors involving the orbit.
abstract: Huge ossifying tumors involving the orbit were treated with a combination of craniofacial surgery and microsurgical techniques in two patients. The orbital osteotomy facilitated wide exposure of the tumors and their excision even though the tumors were extremely large. Stable results were obtained in one stage without visual disturbance by simultaneous reconstruction of the resulting bony defects using a free vascularized bone graft even in unfavorable tissue beds such as when one side of the bone graft is exposed to the affected nasal cavity or maxillary sinus. The combination of craniofacial surgery and microsurgical techniques has proven in our experience to be an effective approach to the treatment of a huge orbital ossifying tumor in one stage.
