The morphology of Sella Turcica in individuals with different skeletal malocclusions – A cephalometric study

Abstract

AimsThe aim of the study was to analyze the morphology and expedient the linear dimensions of Sella Turcica among Indian individuals having Skeletal Class I, Class II and Class III pattern, and then to determine if differences exist with different skeletal patterns. Methods and materialThe lateral cephalogram of 150 patients (75 males and 75 females), aged 18–30 years who reported for various treatments of malocclusions were studied. Statistical analysis usedAnalysis were done by ANOVA with Tukey's t-test, SPSS version 17.0 was used. P < 0.05 was considered as significant. ResultsThe normal morphology of the sella turcica were seen in 85 of the 150 individuals which was highest (56.66%) in the study group, an oblique anterior wall was present in 11.33% of the subjects, an irregular dorsum sella and sella turcica bridge were seen in 10% of the subjects, pyramidal shaped sella were seen in 6.66% and 5.33% of the subjects had double-contoured sella turcica. No significant difference between males or females in terms of diameter, depth or length was evident. A significant difference was observed among different skeletal patterns and the diameter of sella. ConclusionsThe normal morphology of the sella turcica was seen in approximately 57% of the individuals. The larger diameter values were seen in the skeletal Class III subjects, while the smaller diameter values were observed in the Class II subjects.
