摘　　要：目的研究海绵窦的局部解剖特点，为临床医师提供立体、形象的解剖学资料。方法于2008年3月至2011年11月，应用冷冻铣切技术，完成一成人头颅断层标本的制作，通过计算机对头颅冠状薄层连续切片进行信号标定、提取和三维重建，获得海绵窦有关结构的三维图像。结果共获得390张海绵窦区的0．1mm厚冠状断层，选取6个典型断层，描述了海绵窦区的解剖特点。海绵窦的三维图像显示海绵窦位于蝶鞍两侧，前方在前床突外下方经眶上裂于眼眶相通，后方在后床突两侧与基底窦相通；海绵窦具有四个解剖间隙：前下间隙、后上间隙、内侧间隙和外侧间隙，三维图像形象显示四个间隙的解剖位置和彼此联通关系。结论冠状断层解剖和三维重建相结合形象显示海绵窦区的立体解剖关系。三维重建图像是声像学软件，能够在三维空间用不同速度持续、动态地展示解剖结构。Objective To study the regional anatomy of the cavernous sinus for skull base surgery. Methods Continuous thin sections on coronary plane were performed with freezing milling technique on an head specimen from March 2008 to November 20ll. After segmenting, labeling and extracting in a seraial sec-tions, we finished the three dimensional reconstruction of the cavernous sinus. Results Three hundred and ninety thin coronary sections were obtained. The related structures were described in six typical sections. The cavernous sinuses were located on each side of the sphenoid sella. The sinus connects to the superior orbital fis-sure below and lateral to the anterior elinoid process, opens into the basilar sinuses lateral to the dorsum sellae. The four main spaces within the sinus, identified by their relation to the carotid artery, were the medial, the an-teroinferior, the posterosuperior compartments and the lateral space. The four spaces were located differnently and communicate with each others in three dimensional images. Conclusion Combination of coronary section anatomy and three dimensional reconstruction can display the anatomical characters of the s cavernous sinus. The 3D models are video films that continuously and dynamically display anatomic structures in 3D space at dif-ferent velocities.
