目的探讨颌骨骨折愈合影响因素。方法根据致伤原因、骨折部位及类型、治疗效果及随访结果对350例颌骨骨折病例进行总结。结果通过术后1～6年的随访,按三个等级进行分类,随访结果三个等级分别为Ⅰ级98例占28%,Ⅱ级232例占66.3%,Ⅲ级20例占5.7%。下唇及眶下区麻木的160例中大都恢复正常(156/160),出现面瘫症状的17例则基本无改善。20例复视患者中有18例恢复正常。结论准确诊断,及时复位、固定,选择正确固定方式,防止感染,特别是应用坚固内固定技术能有效提高颌骨骨折治愈率。感觉神经损伤比较容易恢复,而运动神经则比较困难。
Objective To investigate the influencing factors of jaw fracture healing. Methods According to the cause of injury, the location and type of fracture, the therapeutic effect and the follow-up results, 350 cases of jaw fracture were summarized. Results The patients were classified into three grades according to the follow-up of 1-6 years after operation. The three grades were grade Ⅰ 98%, grade Ⅱ 232% 66.3%, grade Ⅲ 20% 5.7%. 160 cases of numbness in the lower lip and infraorbital area mostly recovered to normal (156/160), while 17 cases of facial paralysis showed no improvement. 18 of 20 patients with diplopia returned to normal. Conclusion Accurate diagnosis, timely reset, fixed, select the correct way to prevent infection, especially the application of rigid internal fixation can effectively improve the cure rate of jaw fracture. Sensory nerve injury is easier to recover, while motor nerves are more difficult.
