摘要： 目的: 总结和探讨“7·23”重特大动车事故发生后一线医院收治的口腔颌面部创伤患者的伤情特点。方法：对温州市11家医院收治的111例动车事故中口腔颌面部创伤患者的病例资料进行统计和分析。结果：111例口腔颌面部创伤患者中男女比例为1.27∶1；21～30岁(33．3％)为受伤高峰年龄段。在颌面部创伤中，颌面部软组织伤占81.1％，颌面部骨折占11.7％，牙外伤（牙槽突创伤）患者占7.2％。3例下颌骨骨折患者共发生5处骨折，占骨折的29.4％，发生率最高。合并损伤多发，以四肢损伤和胸部损伤最为多见，分别占31.1%和25.7%。结论：动车事故中口腔颌面部创伤多发，但以软组织伤最为常见，颌骨骨折中下颌骨骨折居多；复合伤多，最常见的是四肢和胸部的损伤。
