Non-metrical morphologic variations of skull foramina were studied with 250 crania of Korean adults. Studied morphologic variationts were presence of supra-orbital foramen(33.3%), frontal foramen(27.7%), accessory infraorbital foramen(13.2%), accessory lesser palatine foramen(41.0%), Vesalius foramen (16.9%), Huschke foramen(18.8%), condylar canal(62.6%) and parietal foramen(49.8%). The ahsence of posterior ethmoidal foramen(0.2%), zygomaticofacial foramen(7.1%) and mastoid foramen(30.2%) was also observed. The variations were presence of the exsutural location of anterior ethmoidal foramen 30.8%), mastoid foramen(35.9%) and incomplete development of oval foramen(4.9%), foramen spinosum(9.6%), hypoglossal foramen(9.6%). And incidence of these variations were compared with 12 different geographical localitics.

The anatomical variations of 112 hypophysis and diaphragma sellae in Korean adult cadavers and coronal CT were studied. 1) The hypophysis was classified 4 types based on superior view. 2) The superior surface of the hypophysis was concave(65.9%) in cadavers and flat(55.3%) in CT. 3) The neural lobe was placed on the center of the posterior surface of the anterior lobe(72.3%). 4) The hypophysis was compressed by the internal carotid artery in 9.6%. 5) The mean A-P length, width and height of the hypophysis were 10.4mm, 14.2mm and 4.8mm in cadavers, respectively. The mean width and height in CT were 13.2mm and 5.0mm, respectively. 6) The width of the hypophysis was significantly different between man and woman. 7) The diaphragma sellae was concave or flat. 8) The diaphragmatic line was average 13.9mm in man and 14.6mm in woman. 9) The diaphragmatic foraman was circular or oval and the A-P diameter was greater than transverse one. 10) Type IIb that diaphragma sellae and hypophysis were concave according to Busch(1951) was 40.4%. 11) The empty sella was found in 14.4%.

The anatomy of the arteries distributing to the ocular rectus muscles has not been well known inspite of their importance during opertions. Eighty orbits of Koreans were dissected under the surgical microscope to find out the entering point and its distribution of each rectus artery. The average numbers of the branches of the artery that piercing the supenor, lateral, medial, and inferior recti were 4, 7, 7 and 6 respectively. The supenor rectus artery tended to pierce the posterior middle one third of the muscle; the medial and lateral rectus arteries tended to pierce the posterior two thirds of the muscles; and the inferior rectus artery tended to pierce the medial two tbrds of the muscle. The arterial branches piercing the anterior one third of the superior rectus were less than 1%, and those of the lateral, medial, and inferior recti were 5%, 10% and 15% respectively. The relationships between the artery and nerve differed in each muscle.

Intactness of arterial supplies is necessary for the external ocular muscles to move properly, however the anatomy of the ocular muscular arteries has not been clarified Therefore, 80 orbits of Koreans were dissected under the surgical microscope and the origins of the rectus arteries were observed. The average numbers of the arising site of the artery to the superior rectus, the lateral rectus, the medial rectus, and the inferior rectus were 1.7, 1.2, 2.2 and 1.1, respectively. The superior rectus artery arose from the superolateral muscular artery in 33.3%. The lateral rectus artery arose from the superolateral muscular arterey in 43.8%, from the inferior muscluar artery in 24.8%. The medial rectus artery arose from the inferior muscular artery in 43.1%, from the superomedial musculal artery in 16.8% and from the ophthalmic artery as a solitary branch in 32.9%. The inferior rectus artery arose from the inferior muscular artery in 83.1% and from the inferolateral muscular artery in 13.5%.
