目的为比较内镜下与显微镜下经鼻-蝶窦入路的解剖标志和显露范围差异。方法对9例汉族成人灌注尸头采用经鼻-蝶窦入路进行解剖,其中4例行显微解剖,5例采用内镜下解剖,在内镜与显微镜下分别对入路的解剖标志和显露范围进行比较。结果在蝶窦内,内镜下可以观察到更多的解剖标志以确定鞍底、海绵窦等重要结构的位置;内镜经鼻-蝶窦入路更易于向颅前窝底、鞍旁海绵窦和斜坡方向扩展。内镜与显微镜下的操作存在较大差异。结论内镜经鼻-蝶窦入路鞍区及其周围的显露范围较显微镜下更大。
Objective To compare endoscopic and microscopic transnasal-sphenoid approach anatomical landmarks and exposure range differences. Methods Nine adult Han cadaveric cadaveric heads were dissected by transnasal - sphenoid sinus approach. Four of them were dissected microscopically and five were anatomized with endoscope. The anatomic landmarks and Reveal the range for comparison. Results In the sphenoid sinus, more anatomical landmarks could be observed under endoscopy to determine the position of the important structures such as sellae, cavernous sinus and so on. The endoscopic naso-sphenoid sinus approach was easier to approach the anterior skull base, sella sponge Sinus and slope direction expansion. There is a big difference between the operation of the endoscope and the microscope. Conclusion The scope of exposure of the endoscopic transsynuse and sphenoid sinus in the sellar region and its surroundings is larger than under the microscope.
