摘要
目的 探讨计算机三维重建技术在颈静脉孔区研究中的应用。 方法 用生物塑化技术制作 1 2mm厚的薄层断面标本 ,在SGI工作站上对颈静脉孔及相关结构进行三维重建。 结果 计算机三维重建图像可显示颈静脉孔区重要神经、血管 ,能够清楚显示颈内动脉、颈内静脉及舌咽、迷走、副神经束与颅底骨结构的三维解剖关系。重建结构能够以单独或联合方式显示 ,并可绕任意轴进行旋转 ,任意径线及角度均可适时测量。
Objective To explore the role of the computerized 3D reconstruction in studying the anatomy of the jugular foramen. Methods Plastination was used to make equidistant serial thin sections with 1^2*!mm in thickness.A SGI workstation was employed to reconstruct the jugular foramen and relative structures in three-dimensions. Results The computerized 3D-reconstruction could clearly display the important nerves and vessels of the jugular foramen,delineate the relationships between the internal carotid artery,internal jugular vein,the bundle of glossopharyngeal,vagus and accessory nerve and the skull base.All structures reconstructed can be represented individually or jointly and rotated continuously in any plane.Any diameter and angle of the structures reconstructed could be measured conveniently.Conclusion The computerized 3D-reconstruction possesses important value in studying the anatomy of the jugular foramen.
