Complete Extensive Heterotopic Ossification of the Entire Free Fibula Flap Vascular Pedicle in Maxillary Reconstruction.

Introduction: Heterotopic ossification is a pathologic extra-skeletal bone formation as a form of aberrant repair process with acquired or genetic etiologies. In plastic surgery, it has been well-described in the burn and trauma patients. Rarely, it can happen along the vascular pedicle of free tissue transfer, and when it happens, it is most commonly in head and neck reconstruction.
