We investigated supraorbital ethmoid cell (SOEC) presence and types in paranasal sinus computed tomography (PNSCT).
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.
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.
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).
我们研究了鼻窦计算机断层扫描（PNSCT）中眶上筛窦气房（SOEC）的存在情况及类型。
对188例成年患者（93例男性和95例女性）的PNSCT图像进行评估，分为SOEC组（n = 87侧）和非SOEC组（n = 289侧，对照组）。在两组中，评估筛前动脉（AEA）切迹与筛顶的距离以及AEA管的存在情况。在SOEC组中，还检查了SOEC类型（1至3型）和SOEC角度。
在87侧（23.13%）检测到SOEC。检测到的SOEC类型中2型最多（71.3%）。SOEC组的AEA切迹与筛顶的距离明显高于非SOEC组。3型SOEC组的AEA切迹与筛顶的距离明显高于2型SOEC组。SOEC组的AEA切迹与筛顶的距离为3.74±1.81mm，非SOEC组为0.68±1.16mm。考虑SOEC类型时，3型的此距离为5.29±2.66mm，2型为3.35±1.35mm，1型为3.
