摘要:

目的 探讨CT仿真内镜(CT virtual endoscopy, CTVE)对经蝶入路相关解剖结构的显示情况,为CTVE在经蝶手术中的应用提供依据。  方法    15具血管灌注成人尸颅进行蝶窦的CTVE重建和内镜解剖,比较两者对解剖结构的显示情况。  结果    CTVE与内镜均能显示浅表的颈内动脉隆起、视神经管隆起、视神经管-颈内动脉隐窝、蝶窦开口、斜坡凹陷的三维解剖图像,两者间的显示率差异无统计学意义(P>0.05)。通过传输函数设计技术(Transfer functions)、动态调高观察阈值,CTVE能显示鞍底深部的颈内动脉及视神经管、模拟部分手术过程,与内镜解剖所见类似。  结论    CTVE能显示鞍底浅表及深部重要结构的三维解剖图像,可用于指导经蝶手术的术前计划的形成及术中定位。

Abstract:

Objective To provide basic data for the application of CTVE to transsphenoidal surgery. Methods In fifteen injected adult cadaveric heads, the CTVE images of sphenoid sinus were reconstructed by Navigator Guide software, and then compared with the endoscopic images. Results CTVE and endoscope could display the superficial anatomic landmarks such as the sphenoid ostia, optic prominence, carotid prominence, opticocarotic recess and clival indentation of sphenoid sinus in a three-dimensional mode. The difference between the display rates of CTVE and endoscope are not statistically significant(P>0.05). CTVE could display all the anatomies of the underlying carotid ateries by Transfer Functions. By gradual heightening of the threshold, CTVE could display the underyling optic canals and simulate the procedures of sellar floor exposure and optic nerve decompression, which were similar to the endoscope. Conclusion CTVE can display the superficial and underlying anatomies involved in transsphenoidal surgery in a three-dimentional mode. CTVE can be a valuble imaging tool for transsphenoidal sugery.
