摘要
目的为安全的进行鼻内镜下蝶窦开放术提供薄层断层解剖学资料。方法通过冰冻铣切技术获得层厚为0.1mm的连续横断面断层解剖图像,对蝶窦及其重要毗邻结构进行观察和测量。结果46.7%视神经管以及70%颈内动脉在蝶窦外侧壁处形成突起。蝶窦口上下径为(3.41±0.56)mm,左右径为(2.24±0.35)mm,蝶窦口与颈内动脉、视神经管间的距离分别为(19.63±2.26)mm、(8.83±1.42)mm。结论通过对蝶窦连续横断面薄层断层解剖图像的追踪观察,可以获得蝶窦及其重要毗邻结构的相关数据。
Objective To provide lamellar sectional anatomy data for endoscopic sphenoidotomy. Methods The digital freezing milling technique was used to obtain the continuous sectional data as thin as 0.1 mm of 15 cadaver heads（30 sides） without organic lesion. The sphenoid sinus and some surrounding structures were observed and measured on typical and continuous cross sectional image. Results 46.7% of optical nerve canal and 70% of internal carotid bulged on the area of the lateral sphenoid sitars. The maximal vertical longitude of the sphenoid sinus was （3.41 ± 0. 56） mm and the maximal horizontal longitude was （2.24 ±0.35）mm. The distance of the aperture of the sphenoid sinus to the intermal carotid was （19.36 ± 2.26）mm, and the distance of the aperture to the optic nerve canal was （8.83 ±1.42）mm. Conclusion The lamellar sectional image obtained from the digital freezing milling technique offers a better understanding of complex anatomical structures and provides sectional anatomy data for sphenoidotomy.
