目的 :提高颌面部陈旧性骨折复位后固定的可靠性 ,修复和防止伤后畸形 ,尽早恢复患者口颌功能。方法 :利用医用钛合金小夹板骨内固定 ,治疗口腔颌面部陈旧性骨折。结果 :1 996年 8月～ 1 998年 9月已完成 2 2例 ,全部成功。结论 :在颌骨陈旧性骨折中使用该技术 ,既利于骨段间的稳定 ,加速其愈合 ,又缩短了颌间栓结固定的时间 ,对颌面部陈旧性骨折是一种理想的固定技术 Objective: To improve the reliability of fixation of maxillofacial old fractures after reduction, to repair and prevent post-traumatic deformities and to restore the maxillary function of the patients as soon as possible. Methods: To treat the old fracture of oral and maxillofacial region by using the medical titanium alloy splint. Results: From August 1996 to September 1998, 22 cases were completed, all of which were successful. Conclusion: The use of this technology in the old fracture of the jaw is not only conducive to the stability between the bone segments, accelerate its healing, but also shorten the time of intermaxillary embolectomy, which is an ideal fixation technique for the old fractures of the maxillofacial region
