The Shape and Size of the Sella Turcica in Turkish Subjects with Different Skeletal Patterns

Rabia Merve Celik Karatas, F. Betül Kahraman & Mehmet Akin


The aim of this study was to describe the shape and measure the size of the sella turcica in Turkish subjects with different skeletal types. Lateral cephalometric radiographs of 150 patients (75 females and 75 meals) were taken and distributed according to skeletal classification; 50 Class I, 50 Class II, and 50 Class III. The sella turcica on each radiograph was analyzed and measured to determine the shape of the sella, in addition to the linear dimensions of length, depth, and diameter. In statistical comparison, Independent sample t- test or Mann-Whitney U test, one-way analysis of variance and post-hoc Tukey HSD, and Fishers Exact tests were used at p<0.05 level. The statistical analysis showed that there were no significant differences in linear dimensions of the sella turcica between genders. Normal shape of the sella turcica was seen in the majority of the subjects (68,7%), regardless of gender, age or skeletal type. When skeletal type was compared with sella size, a significant difference was found in the diameter of sella between the Class I and Class II subjects. Larger diameter values were present in the skeletal Class I subjects, while smaller diameter sizes were apparent in Class II subjects. Sella shape and dimensions reported in the current study can be used as reference standards for further investigations involving the sella turcica area in Tukish subjects.
