Introduction: The relationship between shape and morphology of sella turcica and
different vertical skeletal classes has been a focus of investigation since the late 19th
century. By introducing Cone Beam Computed Tomography (CBCT) to the orthodontic
field, studying such a relation became possible and accurate. Aim: The aim of this
study is to determine the relation between the linear dimensions of the sella turcica and
different vertical growth patterns in adults using CBCT. Patients and Methods: Conebeam
computed tomographic images of 54 adults were acquired. They were grouped
into three groups of 18 each: Vertical growth pattern group, normal growth pattern
group and horizontal growth pattern group. The length, depth, and diameter of sella
turcica were measured in each group using Dolphin software program. In addition;
Mimics Medical Software was used for accurate volumetric analysis of sella turcica.
Results: Regarding Length (mm), Depth (mm), and Diameter (mm) of sella turcica,
there was a statistically non-significant difference between the three groups. As for
Diameter (mm); there was a statistically significant positive correlation with SN-MP
in the High angle group. Regarding Volume, there was a statistically non-significant
positive correlation with SN-MP in all groups. Conclusion: The length, depth, diameter
and volume of sella turcica showed no difference in all groups. There was a statistically
significant positive correlation between SN-MP angle with sella turcica diameter in the
High angle individuals.
