目的:探讨颌间牵引钉牵引与坚固内固定治疗下颌骨骨折的临床疗效。方法:选取63例下颌骨骨折病人,均行小型钛板内固定术,术后32例行牵引钉颌间牵引1~2周。结果:单发性骨折试验组与对照组术后愈合无差异,多发性骨折有差异(P<0.05)。结论:多发性骨折坚固内固定术后应行颌间牵引,比单纯使用坚固内固定术有更明显的治疗效果。 Objective: To investigate the clinical effect of intermaxillary traction nail traction and rigid internal fixation in the treatment of mandibular fracture. Methods: Totally 63 patients with mandibular fractures were treated with mini-plate fixation. Twenty-two patients underwent traction and intermaxillary traction for 1 to 2 weeks after operation. Results: There was no difference between the single fracture group and the control group in the healing of multiple fractures (P <0.05). Conclusion: Multiple internal fixation should be performed after intermaxillary traction, which has a more obvious therapeutic effect than using rigid internal fixation alone.
