Li M, et al. - Via retrospective radiographic evaluation of computed tomography (CT) scans of 76 patients (40 with SOEC, 36 without), researchers sought to characterize the location of the anterior ethmoid artery (AEA) and its relation to the skull base in patients with and without supraorbital ethmoid cell (SOEC) using the Keros classification. Outcomes suggest a higher prevalence of the AEA coursing below the level of the skull base in correlation with the presence of SOEC, in all Keros types, thus placing the artery at greater risk for injury. This highlight the necessity for careful surgical planning to avoid potential orbital complications.
