  • Various techniques are well documented to obtain anatomic reduction, such as reduction forceps, manual reduction, or a combination of these methods. However, these techniques have inherent drawbacks. We propose a new intra-operative technique for anatomic reduction using screw-wire traction for open reduction and internal fixation of mandibular fractures.

  • Background: Variable methods have been introduced for reduction of the zygomatic fractures. The Dingman elevator is used widely to reduce these fractures but is inappropriate in certain types of fractures which require atypical traction vectors. We introduce and examine an alternate method of reducing zygomatic fractures using wire and hook traction. Methods: A retrospective study was performed for all zygomatic fracture patients admitted between 2008 and 2014. Medially rotated fractures were reduced by using a wire looped through an intermaxillary screw secured on the medial side of the zygoma. Laterally rotated fractures were reduced using a hook introduced through an infrazygomatic skin incision. Results: No accidental bleeding or incomplete reduction was observed in any of the cases. Postoperative imaging demonstrated proper reduction immediately after the operation. Follow-up computed tomography study at 1 month after operation also demonstrated proper reduction and healthy union across the previous site of fracture. Conclusion: The hook and wire method allowed precise application of traction forces across zygomatic fractures. The fractured bone fragment could be pulled in the direction precisely opposite to the vector of impact at the time of trauma. Soft tissue damage due to dissection was minimized. In particular, this method was effective in reducing rotated bone fragments and can be an alternative option to using the zygoma elevator.

  • Purpose: Palatal fracture and mandible fracture result in instability of dental arch. Because they divide the maxillary and mandibular alveolus sagittally and / or transversely and comminute the dentition, they permit rotation of dental alveolar segments and significantly increase the potential for fracture malalignment, complicating fracture treatment. Previous treatment of palatal fracture consisted of palatal splint application and rigid palatal vault stabilization. This procedure result in patient's oral discomfort and removal of palate and screw. Mandible fracture often results in malocclusion due to widening of posterior aspect of dental arch. So we introduce more simple method using intermolar traction wiring, which can protect the widening of dental arch and rotation of dental alveolar segment. Methods: Arch bar and intermolar traction wiring with wire 1 - 0, or 2 - 0 was applied. After exposure of fracture line, neutrooclusion was maintained with intermaxillary fixation. And then open reduction & internal fixation on maxillary fracture line, commonly maxillary buttress, alveolar ridge, pyriform aperture except palatal vault or mandibular fracture line. After 1 week, intermolar traction wiring was removed. We checked occlusion and postoperative radiologic finding. Results: From June of 2007 to October of 2007, 10 patient, who have maxillary fracture with palatal fracture and mandible fracture, underwent open reduction & internal fixation with intermolar traction wiring. All have satisfactory occlusion and there were no complication, like gingiva disease, mouth opening impairment and nonunion. Conclusion: The intermolar traction wiring accompany open reduction and internal fixation can be alternative method for restoration of dental arch in facial bone fracture.

  • Purpose: It is relatively unusual that infraorbital rim fracture is accompanied by nasal bone fracture. In order to correct effectively, subciliary approach and intranasal manipulation are applied simultaneously. But if reduction is not successful, intranasal manipulation may become aggressive and this often causes complications. We introduce a method using intermaxillary fixation screws for decreasing such complications and effective reduction of fracture. Methods: Total seven patients with fracture of frontal process of maxilla were treated with this method. The fracture site was exposed through the subciliary approach, and one or two screws were inserted into the displaced fracture fragment. During the traction of the screws using the wire, the fracture fragment was pushed upward from the intranasal side using an elevator supplementarily and fixed with a plate and the screws. Results: In all patients, the fracture fragment was reduced successfully and no complication occurred during one year's postoperative follow-up. Conclusion: When reduction cannot be attained through a bone hook or an elevator alone, reduction of fracture fragment can be done easily using intermaxillary fixation screws. This method is less likely to cause a mucosal injury because intranasal manipulation is not aggressive. Furthermore, as the screw can be inserted and removed easily, this method is considered effective not only for fracture of frontal process of maxilla but also for fractures in other regions.
