Three-dimensional reconstruction of the orbital floor is the key procedure for a primary or secondary orbital deformity. After the unaffected side is mirrored onto the affected side using the patient's computer-tomography database, the defect can be reconstructed virtually. A measurement procedure that calculates the virtually reconstructed orbital surface data is available. These data are sent to a template machine that reproduces the physical surface. A flat titanium mesh can then be adjusted preoperatively to the spatial configuration of the anatomical structures. This procedure offers optimal anatomical reconstruction of the orbital floor, especially when the deep orbital cone is affected.
眼眶底的三维重建是原发性或继发性眼眶畸形的关键步骤。利用患者的计算机断层扫描数据库将未受影响的一侧镜像到受影响的一侧后,即可对缺损进行虚拟重建。有一种测量程序可用于计算虚拟重建的眼眶表面数据。这些数据被发送到一台能复制实物表面的模板机。然后可以在术前将一块扁平的钛网调整至解剖结构的空间构型。该程序能对眼眶底进行最佳的解剖重建,尤其是在深部眼眶圆锥受到影响时。
