【摘要】：目的:探讨交互式医学图像控制系统在计算机辅助颌面部骨折手术中的应用价值。为陈旧性的创伤性颌面部不对称患者及严重骨折患者术前进行精确设计手术方案及达到术后良好效果提供可靠依据。材料及方法:对18例拟进行颌面部骨折复位的创伤患者的头面部三维CT断层扫描图像,识别确定重建对象,对骨组织采用灰度阈值法进行自动重建;采用MIMICS软件对获取的医学信息进行建模。根据颌面创伤外科医生制订的方案在模型中完成手术的模拟和骨折断段镜像重建,预测骨折断段的正常位置恢复颌面部的对称性。结果:18例完成了颌面骨组织的患者头面部三维重建模型。镜像模拟了颌骨骨折复位手术移动骨断段过程,预测骨折复位的正常解剖位置,并且以动态动画形式演示,可从任意角度进行观察。实现了颌面部创伤手术中骨折断段复位的正确指导,术后骨组织移位的可视化预测。结论:利用医学影像资料,采用MIMICS软件可实现人头面部复杂结构的三维重建和镜像模拟,可以动态形式完成颌面部骨折手术的模拟复位,尤其对陈旧性、多发性骨折的术前预测骨折断段的复位精度,并提高了骨折复位的准确度和精度。可在计算机屏幕前制定手术方案,进行手术医师术前手术评估和预测,提高了颌面部骨折手术有效性、精确性和矫治效果。
[Abstract]:Objective: to explore the application value of interactive medical image control system in computer-aided maxillofacial fracture surgery. Materials and methods: Three-dimensional CT scans of 18 patients with maxillofacial fractures were performed. The object of reconstruction is identified and the bone tissue is reconstructed automatically by gray threshold method. The medical information obtained was modeled by MIMICS software. According to the plan drawn up by the maxillofacial trauma surgeon, the operation simulation and fracture broken image reconstruction were completed in the model. The normal position of fracture segment was predicted to restore the symmetry of maxillofacial region. Results the three-dimensional reconstruction model of maxillofacial bone tissue was completed in 18 patients. The normal anatomical position of fracture reduction can be predicted and demonstrated in the form of dynamic animation, which can be observed from any angle. Conclusion: using medical image data and MIMICS software can realize three-dimensional reconstruction and mirror image simulation of complex structure of human head and face, and can dynamically complete the simulated reduction of maxillofacial fracture. Especially for the old and multiple fractures, the reduction accuracy of fracture segment is predicted before operation, and the accuracy and accuracy of fracture reduction are improved. The surgical plan can be made in front of the computer screen, and the surgeon can evaluate and predict the operation before operation. Improve the effectiveness, accuracy and correction of maxillofacial fractures.
