ABSTRACT

The measurements of skull in roentgenogram were made in 234 cases of korean adults, 128 male and 106 female. Results were obtained as follows. The Cephalic index was 84.7 in male, 84 in female, and 84.09 in both gender. The result was greater than other reported results. The Anterior-Posterior(AP) diameter of pituitary fossa was 1.19+/-0.14cm in male, 1.21+/-0.16cm in female and 1.20+/-0.15cm in both gender. The result was greater than other results. The depth of pituitary fossa was 1.00+/-0.13cm in male 0.99+/-0.12cm in female and 1.20+/-0.99cm in both gender. The mean value of AP diameter and depth of pituitary fossa was greater than the other reported results. The Basal Angle was 127.20+/-5.23 in male, 127.86+/-5.07 in female and 127.50+/-5.21 in both gender, which were smaller than other results. The sphenoid type was classified into 3 types as sella, presella, and concha. The percentage of each type was : sella type with 78%, presella type with 20%, and concha type in 2%. The pineal gland calcification rate in korean adults was lower than that of Westerners. The occurance of Metopic suture and Mendosal suture in simple skull X-ray was rare. We believe the above measurement will provide helpful information in planning a surgical approach as well as in understanding the data discrepancies between skulls of the Asian and European populations.
