Surgical success depends strongly on optimal patient selection and surgery planning, for which a careful assessment of tumor characteristics, approach trajectory, and bony anterior skull base anatomy is required. Still, morphometrical studies searching for relevant anatomical factors with surgical relevance when intending a cSOM for ASBM resection are lacking.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nBilateral cSOM was done in five formaldehyde-fixed heads toward the areas of origin of ASBM. Morphometrical data with potential relevant surgical implications were analyzed.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nThe more tangential position of the cSOM with respect to the olfactory groove (OG) led to a reduction in surgical freedom (SF) in this area compared to others (P<\/jats:italic> < 0.0001). Frontal lobe retraction (FLR) was also higher when approaching the OG (P<\/jats:italic> < 0.05). Olfactory nerve mobilization was higher when accessing the planum sphenoidale (PS), tuberculum sellae (TS), and anterior clinoid process (ACP) (P<\/jats:italic> < 0.0001). OG depth and the slope of the sphenoid bone between the PS and TS predicted lower SF and higher frontal retraction requirements along the OG and TS, respectively (P<\/jats:italic> < 0.05). In contrast, longer distances to the ACP tip predicted lower SF over this structure (P<\/jats:italic> < 0.01).<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nAlthough clinical validation is still needed, the present anatomical data suggest that assessing minicraniotomy\u2019s position\/extension, OG depth, the sphenoid\u2019s slope, and distance to ACP-tip might be of particular relevance to predict FLR, maneuverability, and accessibility when considering the cSOM for ASBM resection, thus helping surgeons optimize patient selection and surgical strategy.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_107_2024","type":"journal-article","created":{"date-parts":[[2024,5,24]],"date-time":"2024-05-24T06:42:25Z","timestamp":1716532945000},"page":"168","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
