In trans-sphenoidal pituitary adenoma surgery the sella turcica is opened between the internal carotid arteries. Three-dimensional image processing methods were applied in this study to avoid the risk of damaging the arteries during the opening of the anterior wall of the sella. By using graphical software it was possible to combine the anatomies of the carotid arteries and the sellar wall into one non-perspective three-dimensional image. With a perspective image (virtual endoscopy), the sphenoid sinus landmarks were presented as if looking through a nasoendoscope. This also facilitated preoperative planning but the non-perspective images, with the carotid arteries marked, were found to be the most useful and suitable for clinical routine. The pituitary tumor itself and its relations with the adjacent structures were best evaluated from magnetic resonance imaging scans but, for the opening of the sellar wall and in the three-dimensional orientation with endoscopy, three-dimensional computerized tomography imaging with the carotid arteries marked was found to be helpful.
在经蝶窦垂体腺瘤手术中，蝶鞍在颈内动脉之间打开。本研究应用三维图像处理方法，以避免在打开蝶鞍前壁时损伤动脉的风险。通过使用图形软件，可以将颈动脉和蝶鞍壁的解剖结构组合成一个非透视三维图像。通过透视图像（虚拟内窥镜），蝶窦标志呈现出仿佛通过鼻内窥镜观察的效果。这也有助于术前规划，但发现带有标记颈动脉的非透视图像对临床常规最为有用和合适。垂体肿瘤本身及其与相邻结构的关系最好通过磁共振成像扫描进行评估，但对于蝶鞍壁的打开以及在内窥镜三维定位中，发现带有标记颈动脉的三维计算机断层扫描成像很有帮助。
