In order to analyze the factors affecting incidence angle and incident point when conducting a general radiography using Sella Turcica, the length and width of the head bone according to age and gender, length and width of Sella Turcica, and the distance between the front and the top of EAM to Sella Turcica were measured. The subjects were 400 patients who underwent a Skull series. For statistical analysis, t-test and ANOVA analysis were conducted using SPSS Ver.22.0. For post-test, Duncan was conducted and if the results were 95% or more (p<.05), it was determined to be significant. As a result of this study, the average length of the head bone was 177.45 mm, where the males were 182.84 mm and the females were 172.05mm showing that males were measured longer (p<.001). The width of the head bone was 116.98mm on average, where the males were 119.18mm and the females were 114.77mm(p<.001) showing that males were measured longer. The average length of Sella Turcica was 4.59mm, where the males were 4.54mm(p<.001) and the females were 4.63mm(p<.001) showing that females were measured longer. The average length of Sella Turcica was 7.08mm, where the males were 7.01mm(p<.001) and the females were 7.16mm(p<.001) showing that females were measured longer. The general radiology examination of Sella Turcica at a medical facility should be conducted in consideration of age and gender in accordance with the characteristics of Koreans.
