Abstract: The purpose of this study was to analyse the linear and area dimensions and morphological shape of
sella turcica to determine if differences exist due to gender or age and compared with available global data. A
total of 183 (113 men and 70 women) Malay subjects who had their computed tomography (CT) scan at the
Radiology Department, Hospital University Sains Malaysia (HUSM) for ordinary diagnosis not related to
craniofacial deformities. The selected age groups were divided into four groups as children (0-6 years), preadolescents
(7-12 years), adolescents (13-20 years) and adults (21-35 years). The images were processed using
Mimics V17.0 software. Conventional measurements included three different heights of the sella turcica (anterior,
posterior, median), its length, diameter, area and width, measured in relation to the Frankfort reference line
(FH). Morphometric methods were used to assess shape. No significant differences in size of the sella were
found except at sella height anterior between genders. When age was evaluated, significant differences were
found among all age groups. The study found that sella turcica presented with a three different shapes: in a U
shape (57.9 %), in a J shape (24.5 %) and shallow (17.5 %). Sella shape and dimensions reported in the current
study can be used for discovering Pathological enlargement of the pituitary fossa and may also be helpful in
providing reference data in the assessment of racial, gender and age specific variation in Malay population.
