摘要
目的对蝶窦进行冠状位薄层断层解剖学研究。方法通过冰冻铣切技术获得层厚为0.1mm的连续冠状位断层解剖图像观察蝶窦及其重要毗邻结构。结果75%的蝶窦为鞍型,蝶窦中隔居中者为15%,60%视神经管以及75%颈内动脉在蝶窦外侧壁处形成突起。结论通过对蝶窦连续冠状位薄层断层解剖图像的追踪观察可以为安全行蝶窦开放术提供蝶窦及其重要毗邻结构的相关资料。
Objective To provide lamellar coronal sectional anatomy data of coronal sectional anatomy for endoscopic sphenoidotomy.Methods A digital freezing milling technique was used to obtain continuous sectional data of coronal anatomy as thin as 0.1 mm from 10 cadaver heads（20 sides）without organic lesions.The sphenoid sinus and some surrounding structures were observed on typical and continuous coronal sectional images.Results 75% of the sphenoid sinus was the sellae type,only 15% of the septum was located in the median sagittal section,and 60% of the optical nerve canal and 75% of the internal carotid bulge were on the area of the lateral sphenoid sinus.Conclusion The lamellar coronal sectional image obtained from the digital freezing milling technique offers a better understanding of complex anatomic structures and provides sectional anatomy data for sphenoidotomy.
