Abstract
- BACKGROUND AND OBJECTIVES
This research aimed to evaluate the prevalence of specific frontal recess cells in Koreans using the classification developed by Lee, et al.
SUBJECTS AND METHOD
Frontal recess was studied using high resolution CT scans of normal 60 Koreans.
RESULTS
Three volunteers were found to have sinusitis around frontal recess in CT and therefore were excluded from this study. Agger nasi cells were observed in 107 sides (94.0%), frontal cell type 1 in 26 sides (22.8%), type 2 in 16 sides (14,0%), type 3 in 9 sides (7.9%) and type 4 in 0 side (0.0%). Frontal bullar cells were observed in 16 sides (14.0%), suprabullar cells in 45 sides (39.5%) and supraorbital ethmoid cells in 3 sides (2.6%). Intersinus septal cells were observed in 10 sides (8.8%) and terminal recess in 76 sides (66.7%).
CONCLUSION
This is the first study conducted about the Korean prevalence of frontal recess cells using the new classification.
