초록

Background and Objectives Endoscopic management of frontal sinus disease remains a difficult task. In order to minimize the risk of intracranial complication, easily identifiable landmarks and measurements should be required. This study aims to identify standard distances from the columella to the anterior and posterior borders of the frontal sinus ostium in Korean men and women.
Subjects and Method We obtained the sagittal images taken from 30 men and 30 women. Measurements from the columella to the nasofrontal beak (NFB) and anterior skull base (ASB) were made. Also, the angle between the lines of the columella to the ASB and hard palate was measured.
Results The mean distance from the columella to the NFB was 55.3±3.9 mm in men and 52.1± 4.7 mm in women (p＜0.01). The mean distance from the columella to the ASB was 62.1±4.5 mm in men and 59.0±4.7 mm in women (p＜0.01). The mean angle between the lines of the columella to the ASB and hard palate was 71.8±4.5° in men and 70.7±4.6° in women (p＞0.05).
Conclusion This study suggests sinus surgeons to stay a distance from the columella of less than 57.6 mm in men and 54.3 mm in women to minimize skull base injury.
