Background: In the branch of orthodontics, to treat the malocclusion diagnosis of the facial skeletal aspects is an important aspect. Cephalometric is one of the means used in diagnosis and treatment planning. The Sella Point (midpoint of sellae turcica) constitutes an important reference point. So, the purpose of this study was to measure the dimensions of sella turcica and its relation with different skeletal patterns, growth patterns and, effective mandibular length. Material and Methods: A cross-sectional retrospective study with 180 pre-treatment lateral cephalographs with the age ranges from 15-26 years consisted of 91 females and 89 males. The length, depth and, diameter of sellae turcica were measured cephalometrically and assessed with different skeletal patterns. Results: There was no significant difference observed between the sella dimension with various skeletal patterns and growth patterns. However, there was a weakly positive correlation between the effective mandibular length and the parameters of sellae turcica. Conclusion: The largest diameter and length were seen in the skeletal class III pattern suggestive of greater space for the accommodation of larger size pituitary gland so more release of growth hormone leading to late mandibular growth in skeletal class III individuals.
