Objective: The aim of this study is to describe shape and measure the size of the sella turcica in subjects with class I and class II skeletal types and to check whether sella can be considered as diagnostic marker for skeletal class II malocclusion.
Material and Methods: Lateral cephalometric radiographs of 44 individuals (age; 15–30 years) were taken and classified skeletally; 22 as Class I and 22 as Class II (11 males and 11 females in both groups). The linear dimensions (length, depth and diameter) of sella turcica were measured. Student’s t-test was used to calculate differences in linear dimensions.
Results: Results show that the sella turcica presented with normal morphology in the majority of subjects (61 percent). No significant differences were found in linear dimensions between genders. Significant difference was found in the depth of sella between Class I and Class II subjects (p<0.05) with smaller depth measurements in skeletal Class II subjects.
Conclusions: Significant difference was found in depth of sella between Class I and Class II subjects with smaller depth measurements in Class II subjects. It is concluded that size of sella turcica can be used to approximate the size of the pituitary gland in skeletal Class II malocclusion. Skeletal class II cases due to mandibular deficiency are associated with smaller depth of pituitary fossa.
