Abstract：
OBJECTIVE: To assist in surgical planning in endoscopic approaches, we analyzed the morphometric measurements of the superior orbital fissure (SOF) and optic canal (OC) by three-dimensional multislice computed tomography (3D MDCT) and evaluated them according to age, gender, and lateralization.
METHODS: The study analyzed 219 MDCT images (114 women, 105 men) from individuals aged 18-90. Measurements of SOF and OC were performed on 3D MDCT images in the axial plane and with 3D-Slicer software.
RESULTS: The distance between the infraorbital foramen and the anterior entrance of the maxillary sinus (CBW) (p < 0.001), the distance between the CBW and the lateral point of the SOF (p = 0.001), and the Angle 1 (p = 0.028) were higher in women than in men. While the SOF length and on 3D the SOF width were higher in women than men (p < 0.001 and (p = 0.001, respectively), the lateral wall length OC was higher in men than women (p = 0.045). According to SOF classification, SOF length was highest in type II and lowest in type VIII (p = 0.025), SOF width was highest in type I and lowest in type VI (p < 0.001). No significant difference was found based on age groups and lateralization in all parameters.
CONCLUSIONS: We found that as the SOF width increased, the SOF length also increased, and there was a statistically strong positive correlation. These findings can contribute to a more effective and safe operation by improving and updating surgeons\' knowledge about safe distances to SOF in endoscopic procedures from a 3D MDCT perspective.

摘要：
目的：为了协助内窥镜入路的手术计划，我们通过三维多层计算机断层扫描（3DMDCT）分析了上眶裂（SOF）和视神经管（OC）的形态测量，并根据年龄进行了评估，性别,和偏侧化。
方法：该研究分析了219张MDCT图像（114名女性，105名男性)来自18-90岁的个体。在轴向平面上的3DMDCT图像上并使用3D-Slicer软件进行SOF和OC的测量。
结果：眶下孔与上颌窦前入口（CBW）之间的距离（p<0.001），CBW和SOF的横向点之间的距离(p=0.001)，女性的角度1（p=0.028）高于男性。虽然女性的SOF长度和3DSOF宽度高于男性（p<0.001和（p=0.001，分别）），男性侧壁长度OC高于女性(p=0.045)。根据SOF分类,SOF长度在II型中最高，在VIII型中最低（p=0.025），SOF宽度在I型中最高，在VI型中最低（p<0.001）。基于年龄组和所有参数的侧向化均未发现显着差异。
结论：我们发现，随着SOF宽度的增加，SOF长度也增加了，并且在统计学上有很强的正相关。通过从3DMDCT的角度改进和更新外科医生对内窥镜手术中SOF安全距离的了解，这些发现有助于更有效和安全的手术。
