Abstract
Immediate reconstruction using the anterior part of the mandibular ramus was performed for zygomaticoorbital floor defect which occurred due to total maxillectomy. In this method, the coronoid process was attached to the zygomatic body and the lateral cortical bone to the orbital floor, and all parts were fixed by titanium mini-plates and screws. The operation resulted in recovery of a desirable shape and prevention of sinking of the eyeballs. Although the indication of this technique was limited to preserving the mandibular ramus, it was useful for zygomaticoorbital defect.
