目的:观察微型钛板坚强内固定治疗下颌骨骨折的临床疗效。方法:对38例下颌骨骨折的患者行切开复位,微型钛板坚强内固定术,辅以1周颌间弹性牵引,术后X线片检查和临床咬合关系及张口度检查。结果:38例患者手术切口均Ⅰ期愈合,咬合关系均恢复到伤前的状况,术后张口度≥37 mm,X线片复查显示骨折愈合良好。结论:微型钛板坚强内固定具有良好的稳定性,术后辅以1周颌间弹性牵引能恢复正常的咬合关系,手术方法简单,治疗效果满意,是目前治疗下颌骨骨折的较好方法。
Objective: To observe the clinical effect of mini titanium plate internal fixation for mandibular fracture. Methods: Thirty-eight patients with mandibular fractures underwent open reduction, mini-titanium plate internal fixation, supplemented by 1 week intermaxillary elastic traction, postoperative X-ray examination and clinical occlusion and mouth opening examination. Results: All 38 cases underwent primary incision healing, and the occlusal relationship recovered to the pre-injury condition. The mouth opening degree was ≥37 mm after operation. The X-ray examination showed that the fracture healing was good. CONCLUSION: The strong internal fixation of miniature titanium plate has good stability. Postoperative one week intermaxillary elastic traction can restore the normal occlusion relationship. The operation method is simple and the treatment effect is satisfactory. It is a good method to treat mandibular fracture at present.
