目的 :建立颌面部爆炸伤合并颅脑损伤动物模型。方法 :将 0 .12 5gTNT当量的球型爆炸源置于不同距离对兔的颌面部引爆致伤 ,观察致伤效果。结果 :由于球型爆炸源在面部不同部位距不同距离引爆 ,各组间的应力测量结果有显著性差异 ,而且颌面部与颅脑伤情也完全不同。结论 :使用本模型可以复制出不同程度的颌面部爆炸伤合并颅脑损伤的伤情 ,是一种较理想的标准动物模型 Objective: To establish an animal model of maxillofacial explosive injury combined with craniocerebral injury. Methods: The detonating injury of maxillofacial region of rabbits was induced by placing 0.125 g TNT equivalent spherical explosive sources at different distances. The injury effect was observed. Results: Because the ball-type explosive source detonated at different distances from the face at different distances, the results of stress measurement among the groups showed significant differences, and the maxillofacial region and craniocerebral injury were completely different. Conclusion: This model can replicate different degrees of maxillofacial explosive injury associated with head injury, is a more ideal standard animal model
