Background: In the field of orthodontics and dentofacial orthopedics, for treatment of malocclusion, diagnosis of facial skeletal type is one of the important aspects. Sometimes, cephalograms are not enough to determine the facial skeletal pattern. Hence, the relationship between sella turcica and other facial skeletal patterns can guide us to determine the proper facial skeletal type and can also help in treatment planning. Aims: The aim of the study was to investigate the normalcy of the dimensions of sella turcica and comparison of the relationship of sella turcica with different skeletal malocclusions. Materials and Methods: A total of 90 pretreatment digital lateral cephalograms were selected according to the criteria and grouped into 3 groups: Group 1: Class I (n = 30), Group 2: Class II (n = 30), and Group 3: Class III (n = 30). Lateral cephalograms were traced and studied on the basis of sella turcica. The following linear measurements were recorded: length, depth, and diameter of the sella. Statistical Analysis Used: Data were subjected to descriptive analysis for mean and standard deviation of all variables and ranges. ANOVA and a post hoc test (Bonferroni and Sidak) were used for multiple comparisons. P <0.05 was considered as the level for statistically significant data. Results: The linear measurements of length and diameter showed statistically significant differences in Class I, Class II, and Class III (P = 0.005). However, depth showed no statistically significant difference in the groups. Conclusions: The importance of sella turcica is established and normalcy is set by statistical analysis, and the standard values are given for the dimensions of the sella turcica. This can be used for further analysis and reference standards for the Indian population. The length and diameter were statistically significant with different groups. The largest value was given in Class III.
