Ballistic facial trauma can cause complex fractures and overlying soft tissue damage, with a zone of injury that extends beyond the bullet tract. Early skeletal fixation is indicated, and previous large case series describe the use of debrided bone fragments as 'spare part' grafts. This series presents the indications and techniques for simultaneous coronoid bone grafting in 2 patients who sustained a gunshot wound to the right midface and required coronoidectomy. The coronoid process was used as (1) an interposition graft in the lateral buttress of the right maxilla for stability, and (2) an onlay graft on the right inferior orbital rim for contour. Both patients did not have graft infection, extrusion, or malposition at the 1-month clinic follow-up. The coronoid process of the mandible is a viable, safe spare-part option, despite the possible location of the coronoid process within the zone of injury in the reconstruction of complex ballistic facial trauma.
