Abstract
Objective: To study the pneumatization of the supraorbital cell of frontal-ethmoid sinus. Methods:Sixty adult cadaveric head specimens(34 male and 26 female) were studied with special atttention on the pneumatization of the supraorbital cell of frontal-ethmoid sinus, and all specimens were scanned by coronal CT. Results:36. 7% of all the specimens had supraorbital cell of frontal-ethmoid sinus and 36. 4% occupied the whole roof of orbit. The thickness of the inside and lateral anterior base of skull were 0. 3±0. 1 mm(0. 1-0. 4) mm and 0. 2±0. 1 mm(0. 1-0. 3) mm and the thickness of the anterior base of skull was 0. 9±0. 3 mm (0. 4-1. 8) mm in no pneumatization of the supraorbital cell of frontal-ethmoid sinus. The result of CT scanning coincided with the result of anatomical observation. Conclusion: To know the pneumatization of the supraorbital cell of frontal-ethmoid sinus is very important for the nasal minimal-invasive operation.
