METHODS: The study was conducted on 10 patients with orbital floor blow out fracture. A graft harvesting guide was virtually constructed based on the defect using mirroring of the normal side. The virtual guide and the defective orbital floor were then printed. The graft was harvested using the guide and adjusted to the defect using the model, finally seated in place.
RESULTS: All patients showed no enophthalmos or diplopia. Orbital volume was comparable for both traumatised and normal orbits with no statistical significance difference (p value 0.28), and orbital volume ratio was 101.76 ± 4.7%.
CONCLUSIONS: The use of graft harvesting guide and orbital floor models for intraoperative graft moulding showed promising results.
方法:对10例眶底爆裂骨折患者进行研究。实际上,使用正常侧的镜像基于缺陷构建了移植物收获指南。然后打印虚拟指南和有缺陷的轨道地板。使用引导器收获移植物,并使用模型调整缺损,终于坐下来。
结果:所有患者均未出现眼球内陷或复视。受创和正常轨道的轨道体积相当,无统计学意义差异(p值0.28)。轨道体积比为101.76±4.7%。
结论:使用移植物采集导向器和眶底模型进行术中移植物成型显示出良好的结果。
