[Application of orthognathic surgery in treating long-standing maxillofacial fracture].
OBJECTIVE
To explore the application of orthognathic surgery to treat malunioned fracture of maxillofacial bone, and the methods in reconstructing facial shape and occlusion.


METHODS
20 patients with maxillofacial malunioned fracture were involved in this study, the site of osteotomy and plan of operation were determined preoperatively with three-dimensional CT reconstruction, cephalometric analysis and model surgery. Occlusal guide plate was made in cases with malocclusion. Then osteotomies were performed in planned sites. Rigid internal fixation was conducted after restoring occlusion and facial contour.


RESULTS
All patients were recovered to normal facial contour after operation, and the occlusion was satisfactory. Four cases with maxillary osteotomy developed bone unhealing in the lateral wall of the maxilla, with oral antral fistula in 2 patients.


CONCLUSIONS
With orthognathic surgery and rigid internal fixation, it is easy to reduce long-standing maxillofacial fracture and recover normal occlusion.
