Abstract:
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%.
