ABSTRACT Background: Sella Turcica is a key landmark for determining craniofacial growth and skeletal malocclusions. Any changes in morphology might have a consequence leading to an orthodontic outcome. Aim: This study aimed to explore the connection between sella turcica interclinoid distances, bridging, and various skeletal malocclusions using cone-beam computed tomography (CBCT). Materials and Methods: CBCT scans from 150 adults were retrospectively analyzed. Anterior and posterior interclinoid distances, maxillomandibular dimensions, and Cephalometric angles: Sella-Nasion-A point (SNA), Sella-Nasion-B point (SNB), and A point-Nasion-B point (ANB) angles to determine skeletal classification, clinoid bridging, and sella turcica flattening were evaluated. Results: The posterior clinoid distance was significantly larger in males, measuring 12.10 mm compared to 11.26 mm ( P = 0.029). All skeletal dimensions were also larger in males ( P < 0.05). A weak link was found between interclinoid distances and malocclusion type. Mandibular width was significantly greater in Class III malocclusions, averaging 50.85 mm ( P < 0.05). Clinoid bridging occurred in 2.6% of cases (4/150), and none were bilateral. One instance of sella turcica flattening was discovered in a patient with severe facial asymmetry and Class III malocclusion. CBCT provides an accurate three-dimensional assessment of sella turcica morphology. Conclusion: While there is a notable gender difference, the association between interclinoid distances and malocclusions appears weak. Sella turcica bridging is rare in this study, and it seems to have little impact on orthodontic results.
