Treatment of occlusal disorder caused by old mid-facial fracture

Abstract

Objective: To investigate the treatment results of occlusal disorder caused by old mid-facial fracture. Methods: A total of 299 patients aged 26-51 years were enrolled in this study. All cases experienced a delay of treatment over 4 weeks after injury. The old mid-facial fracture was scanned by spiral CT and model surgery conducted. Ostectomy and rigid internal fixation were performed. Results: The wound was healed by first intention without infection and other complications. After 1-24 months of follow-up, 299 patients achieved well-shaped mid-face and the occlusion was recovered with mouth opening of over 2 cm. Conclusions: Model surgery combined with ostectomy and rigid internal fixation can achieve satisfied treatment results in patients with old mid-facial fractures.
