GIANT AMELOBLASTOMAS OF THE JAWS

This is to report 2 cases of giant ameloblastomas of the jaws which were successfully treated by surgical method. The obtained results were summarized as follows. 1. In case of mandibular giant ameloblastoma, the lesion involved the entire right mandible and left body, which was radically resected and the defect was reconstructed with resin graft. 2. In case of maxillary giant ameloblastoma, the lesion involved left maxilla and left ethmoid sinus, extending to right inferior turbinate beyond the nasal septum, which was radically resected and the left inferior orbital floor defect was reconstructed with silastic block to prevent ptosis and facial deformity. 3. The platysma myocutaneous flap was used to reconstruct the intraoral defect following the previous operation. The flap has several advantages; first it is relatively thin, second it has few technical difficulties, third it is easily mobilized and rotated to the intraoral defect, fourth it causes no esthetic problem.
