Abstract

BACKGROUND AND OBJECTIVES
Frontal sinus trephination requires understanding of frontal sinus anatomy. This study aims to identify frontal sinus depth (FSD) and bone thickness of its anterior table (FBT) using the axial images of paranasal computed tomography (CT) scans.
SUBJECTS AND METHODS
We obtained the axial images taken from 30 men and 30 women. FSD and FBT were estimated at points 5, 10, and 15 mm from the midline (the straight line passing through the crista galli) on each side using the axial CT images.
RESULTS
The mean male FSDs at 5, 10, and 15 mm from midline were 11.08+/-1.92, 11.38+/-2.08, and 11.49+/-2.27 mm, respectively; mean female FSDs were 8.23+/-1.38, 8.47+/-1.65, and 8.87+/-1.76 mm, respectively. Men had significantly larger FSDs than women did at all measurement points (p < 0.001). The mean male FBTs at 5, 10, and 15 mm from midline were 3.59+/-1.11, 3.25+/-0.93, and 3.65+/-1.25, respectively; mean female FBTs were 3.25+/-0.85, 3.11+/-0.91, and 3.28+/-0.87 mm, respectively. There were no significant differences between FBTs of men and women (p > 0.05).
CONCLUSION
These data provide the information about the frontal sinus in Korean adults.
