We retrospectively analyzed the characteristics and treatment of maxillofacial injuries in the patients who were victims of the Wenchuan earthquake on May 12, 2008 to improve the maxillofacial injuries database and provide reference on patients' treatment after earthquake.
We investigated 2944 cases by talking with the patients during the first 1 and half months after the earthquake and analyzed the results.
Of the 2944 patients, 419 (14%) patients had maxillofacial injuries (man:woman, 1:1.07; mean age, 41.3 years old). Approximately 52% of the patients were injured by pressure and burying. Soft tissue injuries (91%) were considerably more prevalent than facial fractures (14%) and dentoalveolar injuries (17%). Of the patients with facial fractures, the numbers of cases of midface fracture (32 patients) were similar to the number of lower face fractures (31 patients). The most vulnerable bone regions were nasal-orbital-ethmoid bone (58.6%) and zygomatic bone (51.7%). Three hundred sixty patients (86%) demonstrated associated injuries, of which extremity injuries were the most prevalent. Ninety-two patients (22%) had wound infections, but only four patients (1%) had a general infection. Of the patients with maxillofacial injuries, only 77 patients (18.4%) received prehospital treatment.
Our analysis of the characteristics of maxillofacial injuries after the Wenchuan earthquake may improve our emergency treatment procedures in future disaster situations.
我们回顾性分析了2008年5月12日汶川地震受害者的颌面损伤特征及治疗情况，以完善颌面损伤数据库，并为震后患者治疗提供参考。
在地震后的前1个半月内，通过与患者交谈对2944例患者进行调查，并分析结果。
在2944例患者中，419例（14%）有颌面损伤（男∶女为1∶1.07；平均年龄41.3岁）。约52%的患者因挤压和掩埋受伤。软组织损伤（91%）比面部骨折（14%）和牙-牙槽损伤（17%）更为常见。在面部骨折患者中，面中份骨折（32例）与面下份骨折（31例）的病例数相似。最易受损的骨区域是鼻眶筛骨（58.6%）和颧骨（51.7%）。360例（86%）患者有合并伤，其中四肢损伤最为常见。92例（22%）患者发生伤口感染，但仅有4例（1%）发生全身感染。在颌面损伤患者中，只有77例（18.4%）接受了院前治疗。
我们对汶川地震后颌面损伤特征的分析可能会改善我们未来在灾难情况下的急救程序。
