The shape and size of the sella turcica in skeletal Class I, Class II, and Class III Saudi subjects

Morphometric analysis of the sella turcica in Turkish individuals with different dentofacial skeletal patterns

“…The remaining 33% of the cases had variations of sella turcica morphologies [4]. Shah et al [35] found that the normal morphology was also seen in approximately 66% of the subjects.…”

“…The normal dimensions of sella turcica range from 4 mm to 16 mm for length, depth, and diameter [4,8,14,16,28]. The discrepancies in those studies may be due to different landmarks representing the same dimensions, different degrees of magnification, or different compositions of the study groups (age, gender, ethnicity, etc.)…”

“…Table 1 shows the sample distribution according to skeletal classes, genders, and age groups. Based on the ANB angle, the individuals were divided into three groups according to the sagittal skeletal dentofacial skeletal pattern: Class I (ANB; 0°-4°), Class II (ANB; >4°), and Class III (ANB; <0°) [4].…”

“…The floor of the sella turcica is the pituitary fossa with the pituitary gland [20,41]. Any abnormal or pathologic status in the gland could cause a variation of the sella turcica shape and the glandular hormones secretion [4].…”

“…In addition, the sella turcica is a vital anatomical landmark in lateral cephalometric analysis for the assessment of cranial morphology and jaw relations, which may affect orthodontic diagnosis and management [4,34]. In the recent literature, whether or not the morphology of sella turcica is the correlation of dentofacial skeletal types is still under investigation [40].…”
