The supraorbital ethmoid air cell (SOEC) is an anatomical variation of the ethmoid air cell system that pneumatizes the orbital plate of the frontal bone. It affects the frontal recess configuration by opening posterior and lateral to the frontal sinus ostium. This cross-sectional observational study includes 100 patients with Supra orbital ethmoid air cells including various pathologies. We picked up the first 100 patients who had SOEC in all the CT PNS done for various sinonasal pathologies. The incidence of the cell was about 43%. The most common type was the cell extending up to the medial wall of the orbit which was noted in 37% of the cases. Cribriform plate was low-lying in patients with SOEC and the most common type was Keros 3 in about 49% of the study group. 83 patients had anterior ethmoid artery (AEA) lying away from the skull base hanging freely in the mesentery. The most common pathologies observed in patients with supraorbital ethmoid cells were chronic rhinosinusitis followed by mucoceles. The recurrence rate of sinusitis is high in patients with SOEC. The recurrences were mostly because of mistaking the SOEC to be frontal sinus or incomplete removal of partition between them. study stresses the importance of SOEC and its orientation preoperatively to avoid complications during and after the surgery. Detailed preoperative evaluation with the CT helps the surgeon to identify the cells, their extent and associated anatomical variations thereby preventing damage to AEA, cribriform plate and lateral lamella and can get good results.
眶上筛窦气房（SOEC）是筛窦气房系统的一种解剖变异，它使额骨的眶板气化。它通过在额窦开口的后方和外侧开口来影响额隐窝的形态。这项横断面观察性研究纳入了100例患有眶上筛窦气房且伴有各种病变的患者。我们选取了在所有因各种鼻窦病变而进行的鼻窦CT检查中发现有SOEC的前100例患者。该气房的发生率约为43%。最常见的类型是气房延伸至眶内侧壁，在37%的病例中可见。筛板在患有SOEC的患者中位置较低，在研究组中最常见的类型是Keros 3型，约占49%。83例患者的筛前动脉（AEA）远离颅底，自由悬于系膜中。眶上筛窦气房患者中观察到的最常见病变是慢性鼻窦炎，其次是黏液囊肿。SOEC患者鼻窦炎的复发率较高。复发主要是因为将SOEC误认为是额窦或它们之间的分隔未完全切除。该研究强调了术前了解SOEC及其方向对于避免手术期间和术后并发症的重要性。通过CT进行详细的术前评估有助于外科医生识别气房、其范围及相关的解剖变异，从而防止损伤AEA、筛板和外侧薄板，并能取得良好的效果。
