目的:探讨陈旧性下颌骨骨折治疗的临床疗效。方法:102例陈旧性下颌骨骨折患者,通过“再骨折”手术复位,行钛板坚强内固定,术后行颌间牵引固定1~2周。术后6个月复查,拍X线片;观察骨折区骨愈合情况,张口度、咬合关系、面部形态以及颞颌关节症状改善情况。结果:102例中,92例患者张口度、咬合关系及面形恢复良好,颞颌关节无异常症状,10例患者咬合关系欠佳,但有明显改善。结论:陈旧性下颌骨骨折患者,通过“再骨折”手术复位并进行坚强内固定,均能达到满意的临床效果。
Objective: To investigate the clinical effect of old mandibular fracture treatment. Methods: One hundred and two patients with obsolete mandibular fractures were treated with “re-fractures” and underwent rigid internal fixation with titanium plates. The patients underwent intermaxillary traction for 1 to 2 weeks after operation. Six months after operation, X-ray films were taken. The bone healing, mouth opening, occlusion, facial features and the improvement of temporomandibular joint symptoms were observed. Results: Of the 102 cases, the mouth opening, occlusion and the shape of the face recovered well in 92 patients. There was no abnormality in the temporomandibular joint. The occlusal relationship was not good in 10 patients, but there was a significant improvement. CONCLUSIONS: Patients with obsolete mandibular fractures can achieve satisfactory clinical results through “” fracture repositioning "and rigid internal fixation.
