To analyze retrospectively 419 patients after the Wenchuan earthquake and 46 after Yushu earthquake with maxillofacial fractures so as to provide reference on patients' treatment after an earthquake.
We investigated 419 patients after Wenchuan earthquake and 46 after Yushu earthquake with maxillofacial fractures who were admitted to the West China Hospital of Stomatology and other 46 hospitals in 10 provinces.
A total of 58 patients had maxillofacial fractures (13.8%) including 33 (56.9%) men and 25 (43.1%) women after the Wenchuan earthquake and 6 (13%) had maxillofacial fractures after Yushu earthquake. Most patients were injured by pressing or burying. The nasal-orbital-ethmoidal region was the most frequent site of the maxillofacial fracture (58.6% in the Wenchuan earthquake and 66.7% in the Yushu earthquake). The most prevalent pattern of maxillofacial fracture was multiple and/or comminuted fractures (87.9% in the Wenchuan earthquake and 100% in the Yushu earthquake). There were 48 (82.8%) patients with associated injuries, and the most common site was extremity injuries (58.6%) after Wenchuan earthquake. Few patients received adequate prehospital treatment, with bandages predominantly. Most patients (65.5% in the Wenchuan earthquake and 100% in the Yushu earthquake) underwent open reduction and rigid internal fixation. We failed to find any patients with generalized infection. However, all patients in our study presented the symptoms of post-traumatic stress disorder.
We analyze the characteristics of maxillofacial fractures after the two earthquakes, so as to improve our medical emergency system when such disasters happen again.
回顾分析汶川地震后收治的 419 例和玉树地震后收治的 46 例颌面骨折患者，为地震后颌面骨折患者的治疗提供参考。
调查汶川地震后和玉树地震后分别入住华西口腔医院和全国 10 个省 46 家医院颌面骨折患者。
共 58 例颌面骨折患者（13.8%），其中汶川地震 33 例（56.9%），女性 25 例（43.1%）；玉树地震 6 例（13%）。多因压砸、掩埋受伤。鼻眶筛区骨折最多见（汶川地震 58.6%，玉树地震 66.7%）。骨折类型以多发性、粉碎性骨折为主（汶川地震 87.9%，玉树地震 100%）。合并伤 48 例（82.8%），以四肢伤最多见（汶川地震 58.6%）。患者多未接受正规的院外急救，以绷带包扎为主。46 例患者中 44 例行切开复位坚强内固定术。未发生感染。患者均存在创伤后应激障碍。
分析两次地震颌面骨折的特点，为再次发生此类灾害时完善医疗应急体系提供参考。
