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。
