目的:对伴有上颌窦感染的上颌骨前壁骨折断端愈合状况进行研究。方法:选5只日本大白兔,双侧上颌骨前壁分别制作骨缺损模型,同时右侧制作上颌窦炎模型做为实验组,左侧为对照组。术后1、2、4、6、8周分别切取骨缺损区,行细菌培养和骨折断端组织学分析。结果:5只大白兔全部健康成活,细菌培养显示各个阶段均有细菌存在,切片中新生组织成分与正常骨愈合成分一致。结论:上颌骨前壁骨折伴有窦腔炎症和少量骨缺损者,骨折处可以顺利愈合。
Objective: To study the fracture healing of maxillary anterior wall fractures with maxillary sinus infection. Methods: Five Japanese white rabbits were selected, and bilateral anterior maxillary anterior wall were made bone defect model. At the same time, maxillary sinusitis model was made on the right side as control group and left side was control group. At 1, 2, 4, 6, and 8 weeks after operation, the bone defect area was excised, and the bacterial culture and fracture histological analysis were performed. Results: All the five white rabbits survived successfully. Bacterial culture showed that there were bacteria in all stages. The fresh tissue in the slices was consistent with the normal bone healing components. Conclusion: The maxillary anterior wall fractures with sinus inflammation and a small amount of bone defects, the fracture can be successfully healed.
