摘要
目的:研究鼻腔及筛窦三维重建的方法及意义。方法:用薄层CT及断层解剖分别对鼻腔及筛窦行三维重建,比较两种方法的优缺点。结果:CT重建可以清晰地显示鼻腔及筛窦的毗邻关系及空间定位,但显示细微结构还有一定困难。结论:与CT比较,薄层切片行鼻腔及筛窦的三维重建可以更好地显示此区域的解剖,并为虚拟手术的发展提供模型。
Objective： To explore a feasible method and its significance of 3 - dimensional reconstruction in nasal cavity and ethmoid sinus. Methods ： Three - dimensional reconstructions of nasal cavity and ethmoid sinus were made by using spiral CT images and sectional anatomic data. The advantages and defects of the two methods were evaluated. Resuit： Spiral CT images showed the syntopy and spatial oriention in nasal cavity and ethmoid sinus, but it is difficult to show the subtle structures. Conclusion： Sectional anatomic data are able to show the subtle structures more accurately than spiral CT images in nasal cavity and ethmoid sinus, and provides a model for development of virtual surgery.
