Supraorbital ethmoid cells (SOECs), anterior ethmoid artery notch and ethmoid roof relation in PNSCT. Journal of Clinical Neuroscience, 110, 7-11.0967-58681532-2653http://dx.doi.org/10.1016/j.jocn.2023.02.003https://hdl.handle.net/20.500.12491/12010Objectives: We investigated supraorbital ethmoid cell (SOEC) presence and types in paranasal sinus computed tomography (PNSCT).Methods: The PNSCT images of 188 adult patients (93 males and 95 females) were evaluated as SOEC group (n = 87 sides), and non-SOEC group (n = 289 sides, control). In both groups, anterior ethmoid artery (AEA) notch-ethmoid roof distance and presence of AEA canal were evaluated. In the SOEC group, SOEC types (type 1 to 3) and SOEC angle are also examined.Results: SOEC was detected in 87 sides (23.13 %). SOEC type 2 was the most detected type (71.3 %). AEA notch-ethmoid roof distance of the SOEC group was significantly higher than those in the non-SOEC group. AEA notch-ethmoid roof distance of the SOEC Type 3 group was significantly higher than SOEC Type 2 group. AEA notch-ethmoid roof distance was 3.74 +/- 1.81 mm in the SOEC group and 0.68 +/- 1.16 mm in the non-SOEC group. When SOEC types were considered, this distance was 5.29 +/- 2.66 mm in type 3, 3.35 +/- 1.35 mm in type 2 and 3.48 +/- 0.92 mm in type 1. In higher SOEC types, SOEC angle; and AEA notch-ethmoid roof distance increased.Conclusion: In more pneumatized SOEC presence, SOEC angle increase, and AEA notch-ethmoid roof distance increases, AEA runs inferiorly in the ethmoid cells and freely below the skull base; and is more susceptible to injury. The surgeons should be more careful not to damage AEA in the FESS when detecting well-pneumatized SOECs (SOEC Type 3).eninfo:eu-repo/semantics/closedAccessSupraorbital Ethmoid Cell (SOEC)Anterior Ethmoid Artery (AEA)Anterior Ethmoid Artery NotchEthmoid RoofSOEC TypesFESSArticle10.1016/j.jocn.2023.02.003110711367807832-s2.0-85147800438Q2WOS:000942647700001Q3
