Methods: Three hundred seventeen (189 female and 128 male) full-head CBCT images were evaluated in this study. Incidence, diameter, shape, confluence to foramen ovale, and distance to anatomic structures of SEF were noted. Results: In the 317 analyzed images, the SEF was identified in 89 (28.1%) images. Of these, 67 (21.1%) were unilateral, 22 were (6.9%) bilateral. The maximum mean diameter of SEF was measured 2.66mm on the right side and 2.82mm on the left side (P = 0.16). The most observed SEF shape was oval with the incidence of 68.5% (P <= 0.05). Confluence was observed in 23.4% of SEF whereof 84.6% were in the left side (P <= 0.05). Conclusion: Observations in this study tender new anatomic parameters regarding SEF incidence, characteristics, and distances to proximate anatomic structures. Knowledge related to SEF variations will be helpful for neurosurgeons and radiologist.eninfo:eu-repo/semantics/closedAccessCone-Beam Computed TomographyForamen VesaliusSphenoid BoneSphenoidal Emissary ForamenArticle10.1097/SCS.0000000000004492295E477E480295436812-s2.0-85050226880Q2WOS:000446576600014Q4
