Abstract: Sella turcica is located in the middle cranial fossa, on the surface of sphenoid body, and its center is the pituitary fossa. Sella turcica is an important structure in the neurocranial and craniofacial complex, which is often used in radiographic analysis. In orthodontics, sella point which is located at the center of sella turcica, is regarded as one of the most commonly used landmarks in cephalometrics. These landmarks, located within the craniofacial region, are used to measure the positions of maxilla and mandible in relation to the cranium. Orthodontists can benefit from studying these structures in diagnosis, studying growth in individuals through superimposition of structures on a longitudinal basis, and evaluating orthodontic treatment results. Sella area is an important region, and may have variation between individuals. Therefore, understanding normal iconography and morphology of sella turcica will help orthodontists recognize the pathological problems in sella turcica. This article reviewed the types of sella turcica and incidence rate of sella turcica bridge.
