Alteration in the size and shape of sella turcica can be considered as a pathologic procedure. These alterations can also occur in some syndromes and craniofacial abnormalities.Purpose: The aim of this study was to evaluate and determine the size and shape of sella turcica in patients with normal, low and high facial height.Material & Methods: In this retrospective study, 300 files of patients who reffered to orthodontics clinic of Shiraz dental school were evaluated. The patients’ mean age was 17.33±1.40 years. At first, lateral cephalograms were scanned and then analyzed with lighting ceph software.
