Abstract: Objective: To summarize the diagnosis and treatment on foreign bodies’ injuries in maxillofacial region, and special emphasis was paid on radiology examination. Methods: 36 foreign body injury cases from Jan 2003 to Nov 2010 were retrospectively reviewed. All patients underwent routine X-ray examination to locate the foreign bodies, while 30 patients need further examined by CT or three-dimensional CT（3D-CT） to evaluate whether the foreign bodies were adjacent to great vessels and nerves, feasibility of the removal and possible risk factors. There were 12 metallic foreign bodies, 24 non-metallic foreign bodies. In 10 cases with early debridement, 6 foreign bodies were removed immediately, other 4 waited to selective surgery. In 26 cases, foreign bodies were eliminated by selective surgery.  Results: 32 foreign bodies were eliminated immediately or later, the other 4 cases were left in bodies and followed-up. Conclusion: 3D CT played an exclusive important role in diagnosis and treatment for non-metallic foreign body injuries. According to their size, location and adjacent to great vessels, we can decide whether and when elimination begins.

摘要： 目的：探讨口腔颌面部异物伤的诊断与治疗及影像学诊断的重要性。方法：选择2003-01—2010-12期间收治的，影像和病历资料完善的口腔颌面部异物存留伤36例。分析异物类型，并对临床疗效进行评估。结果：36例异物存留伤患者中，金属异物12例，非金属异物24例。择期异物取出26例；需要急诊清创者10例，而清创术可一期取出异物者6例，4例延期取出。30例经常规X线片检查后，需经CT或三维CT检查进一步定位，评估手术取出的可行性及风险。其中26例经手术取出，4例保留并观察。结论：三维CT在非金属异物存留伤诊疗中起到重要的作用；必须根据异物大小、部位及与周围大血管的毗邻关系，患者全身情况等综合因素判定是否手术及手术时机。
