Abstract: Objective： To analyze the causes of the infection complication after rigid internal fixation in mandibular fractures. Methods： 72 patients who suffered mandibular fractures after rigid internal fixation surgery from June 2010 to June 2013 were retrospectively reviewed. Results： In the 72 patients, 11 cases (15%) suffered by infection complications. In most cases, infection sites occurred in mandibular angle most with a complicated fractures and/or comminuted mandibular fractures.  6 patients were cured by vigorous treatments, 5 patients were cured after removal of the internal fixation plates. Conclusion: Complicated or comminuted fracture of the mandibular angle may possibly complicated with postoperative infections.

Key words: mandibular fracture, rigid internal fixation, infection, complication

摘要： 目的：分析下颌骨骨折内固定术后感染的原因，为提高临床治疗效果提供依据。方法：分析我院自2010-06—2013-06行下颌骨骨折坚固内固定术的72例临床资料；对感染病例的发生原因及防治措施进行总结。结果：72例患者，经过术后观察及3个月的随访，11例出现术后感染，感染的发生率为15%。感染的发生部位以下颌角居多，骨折的形式以复杂骨折及粉碎性骨折居多，其中6例经积极治疗及对症处理后痊愈，5例取出内固定物后痊愈。结论：下颌骨坚固内固定术后发生感染的原因较多，诸如骨折的原因和方式、骨折的部位和形式、手术方式的选择、术中操作不当、未达到解剖复位、接骨板使用不规范等。注重手术技巧，并针对继发感染的病因进行积极的预防与处理，能有效降低术后感染的发生率。
