This study aimed to measure the supraorbital ethmoid cell (SOEC) and characterize the relationship between the degree of SOEC pneumatization and the position of the anterior ethmoidal artery (AEA) in relation to the skull base.
Computed tomography (CT) scans of 100 patients were analyzed. The correlation between the pneumatization of SOEC and the distance of the AEA from the skull base was explored by Spearman's correlation rho efficient test.
The distance of the AEA from skull base was 3.10 (2.60,3.60) mm in patients with SOEC compared with 0.6(0.40,2.10)mm in those without(P < .001). In 50.5% of the patients, the AEA was located below the skull base; the incidence of this localization was significantly higher in those with SOEC than in those without (78.79%vs22.77%, P < .001). Compared to female patients, male patients owned greater SOEC height (9.65vs8.20mm, P = .007). The SOECs volume (r = 0.45, P < .001), height (r = .30, P = .003), and transverse diameter (r = 0.28, P = .005) were all significantly correlated with the distance of the AEA from the skull base.
The pneumatization of SOEC critically impact the distance between the AEA and skull base. The higher the degree of pneumatization, the farther from the skull base the AEA will be, increasing the risk of complications during nasal endoscopic surgery. These results provide an important reference for protecting the AEA during nasal endoscopic surgery.
本研究旨在测量眶上筛窦气房（SOEC），并描述SOEC气化程度与筛前动脉（AEA）相对于颅底位置之间的关系。
分析100例患者的计算机断层扫描（CT）图像。通过Spearman相关系数检验探讨SOEC气化与AEA距颅底距离之间的相关性。
有SOEC的患者中AEA距颅底的距离为3.10（2.60，3.60）mm，无SOEC的患者中为0.6（0.40，2.10）mm（P <.001）。50.5%的患者中，AEA位于颅底下方；有SOEC的患者中这种定位的发生率显著高于无SOEC的患者（78.79%对22.77%，P <.001）。与女性患者相比，男性患者的SOEC高度更大（9.65对8.20mm，P = 0.007）。SOEC的体积（r = 0.45，P <.001）、高度（r =.30，P = 0.003）和横径（r = 0.28，P = 0.005）均与AEA距颅底的距离显著相关。
SOEC的气化严重影响AEA与颅底之间的距离。气化程度越高，AEA距颅底越远，增加了鼻内镜手术期间并发症的风险。这些结果为鼻内镜手术中保护AEA提供了重要参考。
