ObjectiveThis study aimed to explore the relationship between skeletal patterns and the frequency of sella turcica bridging in a sample of young Turkish adults in order to provide a better understanding of the relationship between craniofacial morphology and sella turcica abnormalities.MethodsA total of 90 individuals aged between 18 and 25 years were examined in this study. The individuals were classified according to their skeletal pattern, specifically Class I, Class II, and Class III. Each group consisted of 15 males and 15 females. The length, depth, and anteroposterior diameter of sella turcica were calculated. The shape and bridging of sella turcica were estimated using lateral cephalometric images. All data were correlated and statistically analyzed according to skeletal patterns, genders, and age.ResultsThe mean length, depth, and anteroposterior diameter of sella turcica were 7.02±2.13, 7.56±1.38, and 10.54±1.3 mm in Classes I-III, respectively. There was no significant difference between the dimensions of sella turcica according to gender and age (p˃0.05). The length of sella turcica was larger in Class III, and the depth of sella turcica was larger in Class II individuals (p<0.05). A total of 44.4% of the individuals had normal sella turcica, while the remaining 56.6% had other types of sella turcica. It was determined that 31.1% of the individuals have no calcification, 62.2% had partial calcification, and 6.7% had total calcification.ConclusionThe normal dimensions, shape, and bridging of the sella turcica can be used by the orthodontist for diagnosis, treatment planning, and evaluation of various pathological conditions associated with the sella turcica.
