정상 한국 성인에서의 전두동 개구부 봉소의 발현 빈도

Abstract

Background & Objectives: This research aimed to evaluate the prevalence of specific frontal recess cells in Koreans using the classification developed by Lee, et al.

Subjects & Methods: 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.
