After thorough clinical and radiological examination, Maxillofacial Surgeon Dr. S. M. Balaji diagnosed ameloblastoma extending from right side of the body of the mandible till the other side. Surgery was planned to remove the lesion and reconstruct the affected jaw portion in a single stage. Through gingivomucoperiosteal flap, complete removal of the lesion along with the involved teeth with sufficient clearance of the bone was done under General anesthesia. Costochondral rib graft was harvested and fixed to it. Flap was approximated and sutured. Patient was happy to have both removal and reconstruction in a single surgery.
