Reconstruction of Deep Circumflex Iliac Artery Free Flap for Multiple Recurrent Ameloblastoma in Mandible.

Ameloblastoma is the most common odontogenic tumor of epithelial origin. These tumors are benign in nature but have a high rate of recurrence and possible malignant development when treated inadequately. However, recurrent ameloblastomas in bone grafts are rare. This article presents a rare case of a multiple recurrent ameloblastoma, with the last recurrence in a nonvascularized free iliac bone graft of the mandible, reconstructed with vascularized deep circumflex iliac artery free flap for the surgical defect. Furthermore, an updated review of the literature on recurrent ameloblastomas affecting the bone graft is provided.
