[Transoral miniplate fixation of mandibular body fracture without maxillomandibular fixation: report of 45 cases].
OBJECTIVE
To assess the efficacy of intraoral open reduction of mandibular body fracture using titanium miniplate rigid fixation and intermaxillary traction titanium screw to rigidly tract the jaw during the operation.


METHODS
54 mandibular fractures in 45 patients were included in this study. After general anaesthesia, the intermaxillary traction titanium screw was inserted in the alveolar bone, between the two incisors, between the canine and the first premolar, between the first molar and the second molar, and the intermaxillary traction was finished with 0.5 mm stainless steel wire. After the mandibular arch and occlusion relationship were returned to preoperative condition, transoral mucoperiosteal incision was made to expose the fracture lines and fragments. Two 2.0 mm titanium miniplates were adapted along the Champy's line of ideal osteosynthesis and secured. After operation the stainless steel wire was released. Panoramic radiograph and clinical examination were applied at the first day and three months after operation to exhibit bone union and occlusion.


RESULTS
Most patients displayed satisfied occlusion and bone union without major complications. Seventeen patients had numbness of the lower lips after operation, and the symptom was disappeared three months later. Two patients had improvement of numbness of the lower lips.


CONCLUSIONS
Intraoral open reduction of mandibular body fracture using titanium miniplate rigid fixation and intermaxillary traction titanium screw showed high efficiency in fixation of the mandibular arch fractures , which occurred in the body and the angle of the mandible.
