Recurrence of Mandibular Ameloblastoma on Autogenous Bone Graft: A Case Report

Author(s): Glenn Eduard E. Oppus, MD and Jesusito S. Zubiri, MD, FPCS


Presented is a case of a 62-year-old female who underwent segmental resection with iliac bone graft reconstruction for recurrent ameloblastoma. Another recurrence was noted 14 years later, this time with involvement of the osseous graft. A search of recurrences on bone grafts showed limited reports in literature. The authors explore possible reasons for this unusual occurrence and present current treatment recommendations in ameloblastoma management.

Ameloblastoma, is an epithelial neoplasm that primarily involves the teeth bearing bones of the face. It comprises 1-3 percent of all head and neck tumors but ranks as the most frequent odontogenic tumor worldwide. Although it is benign and slow growing, it is well recognized by surgeons because of its local destructiveness and its character of multiple recurrences after surgery.

The treatment of ameloblastoma requires complete surgical removal of tumor with margins of normal tissue to reduce recurrences. This is followed by coverage of the defects using vascularized bone flaps, non-vascularized bone grafts or a combined soft tissue flap and metal prosthesis for reconstruction.

The authors present an unusual case of an ameloblastoma recurring on an iliac bone graft.
