Zygomatic arch is a prominent structure among facial bone and this is the major cause of vulnerability from the facial trauma. The fracture of zygomatic arch has been treated by ancillary methods of closed reduction approaching through temporal incision or intraoral incision. But, these methods gas a limitation of reduction force vector and it has a difficulty in maintaining the secure fixation of the reduced unstable fractured bones. All 22 cases of zygomatic fracture were reduced by transcutaneous screw and fixed with external fixation device successfully. There was no post-operative complication, such as non union, malunion, and visible scar. This method also has advantages of less post-operative edema and pain.
