目的：评价影像引导导航在颧眶上颌骨复合体骨折切开复位眶底重建术中的应用效果。在术前计划和三维模拟的基础上，通过对健侧和患侧的叠加和比较，重建畸形区域的正常解剖结构。确定脱位骨的复位位置，并进行手术模拟。结果：通过配准，术中解剖结构与CT图像吻合较好，系统误差为1 mm。在导航系统的引导下，所有病例均行颧眶上颌骨复合体骨折切开复位术及眶底壁重建。通过术后计算机断层扫描检查减少，与术前计划很好地匹配。复位效果与术前计划最大偏差小于2 mm。结论：导航引导下颧眶上颌骨复合体骨折行眶底重建是一种有价值的治疗方法。(C)2010美国口腔颌面外科协会口腔颌面外科杂志68：28-34,2010
Purpose: To evaluate the effectiveness of image-guided navigation on open reduction and orbital floor reconstruction as treatment for zygomatic-orbital-maxillary complex fractures.Patients and Methods: Six patients with zygomatic-orbital-maxillary complex fractures were enrolled in the present study. With preoperative planning and 3-dimensional simulation, the normal anatomic structures of the deformed area were recreated by superimposing and comparing the unaffected side with the affected side. The position of dislocated bone for reduction was defined, and surgical simulation was performed. All patients underwent open reduction and orbital floor reconstruction under the guidance of the navigation system.Results: A fairly accurate match between the intraoperative anatomy and the computed tomography images was achieved through registration, with a systematic error of 1-mm difference. With guidance of the navigation system, open reduction of zygomatic-orbital-maxillary complex fractures and orbital floor reconstruction were performed in all cases. The reduction was checked by postoperative computed tomography scans, with a good match with preoperative planning noted. The maximal deviation between the reduction and preoperative planning was less than 2 mm. The symptoms associated with the orbital floor defects were eliminated, and the postoperative facial appearance of the patients was clearly improved.Conclusion: Navigation-guided open reduction of zygomatic-orbital-maxillary complex fractures with orbital floor reconstruction can be regarded as a valuable treatment option for this potentially complicated procedure.
