Arch bars can be used as definitive treatment of facial fractures or to provide a stable starting point from which to begin open reduction internal fixation. Pediatric fractures and fractures involving the condyle or subcondyle are ideal for definitive treatment with MMF. Placement of MMF arch bars can be tedious, and there are alternative methods of MMF such as IMF screws, but in capable hands it can be a useful surgical tool. It is also necessary to educate patients about the potential complications from MMF placement.
