Background Supraorbital ethmoid cell (SOEC) is one of the most difficult frontoethmoid cells addressed during frontal sinus surgery. It has never been studied in Middle Eastern countries. The aim of work is to study the incidence of SOEC in Egyptians and its effect on frontal and/or ethmoid sinuses affection. Patients and methods Computed tomographic scans of 47 patients of chronic rhinosinusitis were studied for supraorbital pneumatization; presence of the SOEC; its size, side, number, and relation to the anterior ethmoid artery; size of the frontal sinus; and opacity of the frontal and/or ethmoid sinuses. Results The SOEC was encountered in 41 sides (43.6). The incidence of SOEC was least in Far Eastern countries (2.6–7.7%), followed by Europe (10.2–22%), and most prevalent in hot climate countries (35–45%). Conclusion It seems that the incidence of the SOEC has geographical and racial variations. Moreover, there is no association between the opacity of the SOEC and the incidence of frontal and/or ethmoid sinuses affection in chronic rhinosinusitis.
