Purpose: Many approaches have been used for the reconstruction of mandible after resection of head and neck tumor. Vascularized or non vascularized bone grafts, titanium meshes with iliac particulate cancellous bone and marrow have been used to reconstruct the mandible as a major technique because of its high success rate. However, reconstruction of these techniques had a problem with a shape identical to the resected mandible. We experienced 2 cases of mandibular reconstruction which was performed using a regrafted bone reconstruction technique.
Patients and methods: Two male patients aged 70 and 76 years were treated for recurrent ameloblastomas. Cortical bone tray was obtained after removing tumor and was heat-treated in an autoclave for 30 min to cause tumor cell death. The heat-treated bone was returned to its original place with a titanium plate. Iliac particulate cancellous bone and marrow (PCBM) was grafted into the lumen of the cortical bone tray.
Results: In our 2 patients, 2 years after surgery, the reconstructed mandible was perfectly taken, and no postoperative complications occurred.
Conclusion: This technique was able to completely reconstruct a three-dimensional mandibular form and resort the normal shape of the mandible. Heat-treated oromandibular reconstruction is a useful technique that minimizes orofacial deformities.
