The purpose of this study was to describe and measure the size of sella turcica in subjects with different skeletal types. Lateral cephalometric radiographs of 120 individuals (60 males and 60 females) with an age range of 11 to 26 years were taken and distributed according to skeletal classification: 40 class I (ANB: 20–40), 40 class II (ANB: >40), and 40 class III (ANB: <20). The sella turcica on each radiograph was analyzed and measured to determine the linear dimensions of length, depth, and diameter. Student’s t-test was used to calculate differences in linear dimensions, while a one-way analysis of variance was performed to study the relationship between skeletal type and sella size. No significant differences in linear dimensions between genders could be found. When age was evaluated, significant differences were found between the older (15 years or more) and the younger (11–14 years) age groups at the 0.01 and 0.001 levels for length, depth, and diameter. Sella size of the older age group was larger than in the younger age group. When skeletal type was compared with sella size, a significant difference was found in the diameter of sella between the classes II and III subjects (p < 0.01). Larger diameter values were present in the skeletal class III subjects, while smaller diameter sizes were apparent in class II subjects (multiple comparison tests). When gender, age, and skeletal type were all compared with the size of the sella (regression analyses), age was significantly related to a change of length (p < 0.01) and diameter (p < 0.001).
