Treatment of sagittal maxillary fractures / 实用口腔医学杂志

ABSTRACT

Objective:To evaluate the technique of reduction and rigid internal fixation of sagittal maxillary fracture. Methods:15 cases of sagittal maxillary fracture were reviewed. Occlusal guide plates were prepared preoperatively by model surgery analysis in 10 cases; Le Fort ? osteotomy and down-fracture were done in 8 cases; Pterygomaxillary junctions were also separated in the other cases. Internal fixation was applied along the anterior maxillary surface by using microplates in all 15 cases. Results:Anatomically reduction was achieved in all cases; Occlusion of 14 cases was corrected except one case of fracture re-displaced. Conclusion:Orthognathic technique is effective treatment of sagittal maxillary fracture; One microplate applied along anterior maxillary surface may be not enough to ensure the fixation of sagittal maxillary fracture.
