The Optic Strut—CBCT Pneumatization Pattern and Prevalence

(1) Background: The optic strut (OS) is a critical landmark for clinoid and paraclinoid surgical interventions. To our knowledge, the current literature only mentioned OS as possibility lesser sphenoidal wing (LSW) pneumatization path, without proper study of patterns prevalence within this structure. Thus, aim was to fill in missing information. (2) Methods: A retrospective on 80 cone beam computed tomography (CBCT) files conducted assess origins OS. (3) Results: were: 56.25% from sphenoid sinus, 1.25% posterior ethmoid air cells (PEAC), 10% Onodi (ONC). Simultaneous unique origin found 26.25% PEAC, 5% ONC. Communication between both LSW roots through 6.25% files. (4) Conclusions: careful radiological examination should precede clinical diagnosis interventions area evaluate postoperative risks possible diffusion infection. Additionally, alters its morphological features thus, utility landmark.
