目的探讨坚强内固定治疗下颌骨骨折的疗效。方法经影像学确诊的178例下颌骨骨折患者采用小型钛板坚强内固定治疗。结果术后随访1年,在咬合关系、开口度、有无下牙槽神经损伤、术后6个月是否达到骨性愈合方面进行疗效评定,优145例,良33例。结论下颌骨骨折采用坚强内固定治疗效果明显。 Objective To investigate the effect of rigid internal fixation in the treatment of mandibular fracture. Methods 178 cases of mandibular fracture confirmed by imaging were treated with small titanium plate internal fixation. Results The patients were followed up for 1 year. The curative effect was evaluated in terms of occlusal relationship, opening degree, the presence or absence of inferior alveolar nerve injury and bone healing at 6 months after operation. There were 145 excellent and 33 good. Conclusion The treatment of mandibular fracture with strong internal fixation is effective.
