Surgical defect closure following endonasal transsphenoidal tumor resection is a critical component of procedural success. Three-dimensional (3D) modeling of relevant skull base anatomy during resection can potentially facilitate design of a custom rigid buttress for gasket-seal closure; however, access to conventional cross-sectional imaging intraoperatively is limited and cumbersome. Endoscopic imaging, by contrast, is always available. This work demonstrates the feasibility of 3D modeling of the visible skull base through structure-from-motion photogrammetric postprocessing techniques, providing a suitable template to design a gasket-seal buttress. Additionally, endoscopic 3D reconstruction of skull base surface anatomy may represent a more robust depiction of the surgical defect than is available by conventional 3D modeling with computed tomography, which suboptimally recapitulates very thin bones and mucosal surfaces typical of this regional anatomy.
经鼻蝶窦肿瘤切除术后的手术缺损闭合是手术成功的关键组成部分。切除过程中对相关颅底解剖结构进行三维（3D）建模可能有助于设计定制的刚性支撑物以进行垫片密封闭合；然而，术中获取传统横断面成像受到限制且操作繁琐。相比之下，内镜成像随时可用。这项工作通过运动结构摄影测量后处理技术证明了对可见颅底进行3D建模的可行性，为设计垫片密封支撑物提供了合适的模板。此外，颅底表面解剖结构的内镜3D重建可能比传统的CT三维建模更能准确呈现手术缺损，传统CT三维建模对该区域典型的非常薄的骨骼和黏膜表面的再现效果欠佳。
