交互式医学图像控制系统在颧眶上颌骨骨折治疗中的应用

Application of MIMICS in the zygomatic-orbital-maxillary fracture

目的探讨交互式医学图像控制系统(MIMICS)在计算机辅助颧眶上颌骨骨折治疗中的应用价值,为术前进行精确设计及术后良好效果提供依据。方法对10例拟进行颧眶上颌骨骨折坚固内固定术的患者行面部三维CT扫描,使用MIMICS软件获取的图像信息进行三维建模,通过虚拟手术制定手术方案,预测和判断骨折位置的复位情况,最终达到良好的手术效果。结果利用MIMICS软件完成术前三维模型重建,并通过模拟手术制定手术方案,预测术后效果,完成骨折手术,达到预期效果。结论采用MIMICS可实现人头面部的三维重建和术前镜像模拟手术过程,以动画形式模拟颧眶上颌骨骨折手术的复位情况,最终提高了颌面部骨折手术的预测性和精确性。

Objective To discuss the value of Materialise’s Interactive Medical Image Control System(MIMICS)about treating the zygomatic-orbital-maxillary fracture in the computer aided surgery,to offer a reliable system for precise surgical planning and good effect.Methods Based on CT images,geometric characteristics of 10 patients’head were collected for a 3 D reconstruction of the human head.Skull,maxilla,mandibula and zygomatic bone were reconstructed and optimized separately by MIMICS.Virtual surgery was applied to develop a surgical plan,to predict and judge the reduction of the fracture position,finally achieve good operation effect.Results MIMICS software was used to reconstruct the preoperative 3 D model,and the simulate operation was applied to make the surgical plan,estimate the result,complete the fracture operation and finally achieve the expected effect.Conclusion MIMICS is a helpful digital tool for computer aided trauma surgery and the prediction of fracture reduction.MIMICS is also a 3 D visualization system for zygomatic-orbital-maxillary fracture surgery,by which surgeons can realize the surgical planning,revising,and preoperative plan making on the computer screen.
