摘要/Abstract

摘要： 目的：为经鼻内镜蝶窦手术、视神经管减压术提供影象解剖学基础。方法：利用螺旋CT三维重建技术对40例(80侧)鼻、鼻窦正常的受试者行蝶窦、视神经管有关解剖数据的影象学测量。结果：两侧视神经管各壁长度均值为：内侧壁12.08±0.62?mm，外侧壁10.16±1.73?mm,上壁9.16±1.17?mm,下壁10.24±1.35?mm。两侧视神经管及蝶窦有关径线均值为：视神经管颅口处：左右径5.57±0.95?mm，上下径4.53±0.78?mm；中部：左右径4.40±0.67?mm，上下径4.36±0.67?mm；眶口处：左右径5.09±0.85?mm，上下径5.90±0.98?mm；鼻小柱前缘中点到蝶窦前壁中点的距离：7.08±0.54?cm；蝶窦最大左右径：17.83±4.38?mm，最大上下径：18.40±3.76?mm，最大前后径：23.19±6.73?mm。结论：螺旋CT三维重建技术可以准确有效地测量蝶窦、视神经管的解剖结构，对经鼻内镜手术具有重要指导价值。

Abstract: To probe into the normal imaging anatomy of the sphenoid sinus and optic canal and its clinical significance. Methods： The sphenoid sinuses and optic canals of 40 normal subjects were examined by MS CT through threedimensional reconstruction method. Results：The length of medial wall, lateral wall ,roof and floor of the optic canal was 12.08±0.62?mm, 10.16±1.73?mm, 9.16±1.17?mm,　and 10.24±1.35?mm, respectively. The width and the height of the intracranial opening ,middle portion, and the intraorbital opening of the optic canal was 5.57±0.95 mm and 4.53±0.78mm，4.40±0.67?mm and 4.36±0.67?mm，　5.09±0.85?mm and 5.90±0.98?mm,　respectively. The distance between the anterior edge of the nasal columella and the middle portion of sphenoid sinus was 7.08±0.54?cm. The maximum transversal diameter of the sphenoid sinus was 17.83±4.38?mm, the maximum vertical diameter was 18.40±3.76?mm, the maximum sagittal diameter was 23.19±6.73?mm. Conclusions： The imaging anatomy of optic canal and sphenoid sinus could be accurately and easily measured by means of threedimentional reconstruction of MS CT, which is of great value to the nasal endoscopic operation of this area.
