 Objective: To find the prevalence of shapes of sella turcica (ST) in different skeletal malocclusion in Nepalese population. Methods: 90 cephalometric radiographs were selected from the database of the Department of orthodontics and were segregated according to different morphology of sella turcica among different skeletal malocclusion. Results: Descriptive analysis showed that bridging, double contour floor and pyramidal shape of dorsum sella of sella turcica were most common among class I malocclusion. Class II malocclusion showed highest prevalence for notching in dorsum sella whereas class III malocclusion showed maximum prevalence of normal and hypotrophic posterior clinoid process. Class I and II malocclusion showed equal prevalence of hypertrophic posterior clinoid process and oblique contour of floor where as oblique anterior wall were equally seen in class II and III malocclusion   Conclusions: The shape of sella turcica can act as an important tool for earlier determination of dentofacial anomalies.
