Abstract
Cephalometry deals with measurement of body parts or radiological specimen. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica were reported. In this study, using computerized tomographic (CT) scans from a tertiary hospital, one hundred and seventy five (175) scans were analyzed using Radiant version 4.2 (Medixant 2017) for determination of sizes and shapes of the sella. Average dimensions from the study include: Length (12.4 mm), A-P diameter (14.1 mm), depth (9.6 mm) and transverse diameter (13.8 mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). In another classification of shape variation, the findings are: Normal (68.6%), anterior oblique (9.1%), pyramidal (6.9%), double contour floor (5.7%), notching on the posterior wall (5.1%) and sella bridge (4.6%). Males tend to have higher sella sizes than females and there is statistical significant difference between them especially in respect to A-P diameter and length parameters. However, there is no sex predilection to shapes.
