The preoperative three-dimensional (3D) modeling of the pituitary adenoma together with pituitary gland, optic nerves, carotid arteries, and the sphenoid sinuses was adopted for routine use in our institution for all pituitary surgery patients. It gave the surgeon a more profound orientation to the individual surgical field compared with the use of conventional 2D images only.
To demonstrate the feasibility of 3D surgical planning for pituitary adenoma surgery using readily available resources.
The computed tomography (CT) and magnetic resonance imaging (MRI) data of 40 consecutive patients with pituitary adenoma were used to construct 3D models to be used in preoperative planning and during the surgery. A freely available, open source program (3D Slicer) downloaded to a conventional personal computer (PC) was applied.
The authors present a brief description of the 3D reconstruction-based surgical planning workflow. In addition to the preoperative planning the 3D model was used as a 'road map' during the operation. With the 3D model the surgeon was more confident when opening the sellar wall and when evacuating the tumor from areas in contact with vital structures than when using only conventional 2D images.
我们机构对所有垂体手术患者常规采用垂体腺瘤连同垂体、视神经、颈动脉和蝶窦的术前三维（3D）建模。与仅使用传统二维图像相比，它能让外科医生对个体手术视野有更深刻的定位。
利用现有资源论证垂体腺瘤手术三维手术规划的可行性。
连续40例垂体腺瘤患者的计算机断层扫描（CT）和磁共振成像（MRI）数据用于构建术前规划和手术中使用的三维模型。使用下载到传统个人计算机（PC）上的免费开源程序（3D Slicer）。
作者简要描述了基于三维重建的手术规划工作流程。除术前规划外，三维模型在手术期间用作“路线图”。与仅使用传统二维图像相比，使用三维模型时，外科医生在打开鞍壁以及从与重要结构接触的区域清除肿瘤时更有信心。
