Introduction. Sella turcica is a part of cranial base where the pituitary is located. It is believed that there is a correlation between the size of the cranial base and thus sella turcica as its integral part and the malocclusions.
The goal of this study was to determine the linear dimensions of ST by radiological analysis of different malocclusions, to determine the existence of sexual dimorphism and to determine the connection between the size of ST with certain malocclusions.
Material. This study is completed upon 90 persons, who were divided into three groups according to the values of ANB angle (30 persons in each group with malocclusion class I, class II and class III according to Angle). The linear dimensions were measured (length, width, diameter) ST.
Results. The study has proven that the persons with the malocclusion of the II class have the lowest and persons with malocclusion class III the highest values of the linear dimensions of sella turcica. In none of the studied groups was sexual dimorphism of the examined parameters present.
Conclusion. According to the results, we may conclude that there is a correlation between the size of sella turcica and certain malocclusions.

Key words: sella turcica, malocclusion
