背景：由于涉及复杂的结构，前颅底手术具有挑战性。嗅丝和视神经损伤可导致术后并发症。本研究旨在利用计算机地形图提供完整的前颅底解剖信息，并根据骨缺损程度对筛窦视神经管（opticcanal，OC）进行新的分类，为鼻内镜下前颅底手术提供参考。方法：对112例患者的计算机地形血管造影图像进行多平面重组后，在冠状面、矢状面和轴位进行测量。利用鼻线和正中矢状线定位筛孔的前、中、后段和眶骨开口。根据骨缺损的程度，将筛窦OC分为4型。结果：筛孔前、中、后段与OC的距离分别为6.23 ± 0.21，6.62 ± 0.26，7.29 ± 0.25，7.76 ± 0.41mm。 筛孔与筛窦连线与水平面的夹角分别为47.50° ± 1.03°、41.67° ± 1.33°、37.20° ± 1.34°。 4种OC的阳性率分别为15.6%、11.6%、31.3%和41.5%。结论：本研究为鼻内镜下经鼻前颅底手术提供了筛孔和枕大孔的解剖学基础。从而提高该手术的手术安全性，并有助于选择合适的内窥镜设备进行手术。
Background: Surgery to anterior skull base is challenging since complex structures are involved. Injury of olfactory fila and optic nerve may result in postoperative complications. In our study, the authors aim to use computer topographic image to provide a comprehensive anatomical information of anterior skull base and set up a new classification of optic canal (OC) in ethmoid sinus by the degree of bony defect, so as to help surgeons in endoscopic transnasal approach to anterior skull base. Method: Computer topographic angiography images of 112 individuals were reviewed, the measurement was performed on coronal, sagittal, and axis planes after the multiplanar reformation. Nostril and mid-sagittal lines were used to locate the anterior, middle, and posterior part of ethmoidal foramina and orbital opening of OC. Further, the authors classified OC in ethmoidal sinus into 4 types by the degree of the bony defect. Result: Distance between nostril to anterior, middle, and posterior part of ethmoidal foramina and OC are 6.23 ± 0.21, 6.62 ± 0.26, 7.29 ± 0.25, and 7.76 ± 0.41 mm, respectively. Angle between line from nostril to ethmoidal foramina and horizontal plane are 47.50° ± 1.03°, 41.67° ± 1.33°, 37.20° ± 1.34°, respectively. For the 4 types of OC, the percentage is 15.6%, 11.6%, 31.3%, and 41.5%, respectively. Conclusions: Our findings provide anatomical information of ethmoidal foramina and OC during endoscopic transnasal approach to anterior skull base, on the basis of some fixed anatomical landmarks. So as to enhance the surgical safety of this procedure and aid in the choice of the appropriate endoscopic equipment for the procedure.
