Analysis and Secondary Management of the Primary Treatment Failure of Jaw Fracture

Objective To analyze the reasons of the treatment failure of jaw fracture primarily treated in other hospitals, and to investigate the principle and right methods of the secondary management. Methods 107 subjects have been secondarily treated since 3 years ago. 71 cases underwent open reduction and rigid internal fixation, 11 cases only intermaxillary elastic traction and fixation, and 25 cases with serious malposition healing of fracture orthognathic surgical correction. Results All of the fractures healed well. Occlusion recovery in 93 cases were satisfied, and in 9 cases were satisfied after postoperative orthodontic treatment or occlusal adjustment. Conclusion It is important to master the principle and right methods of jaw fracture treatment. The short-term intermaxillary traction is essential. The cases with serious malposition healing of fracture can be satisfactorily corrected by orthognathic techniques.
