The aims of the study were to assess sella shape and size in anadolescent Iraqi sample in different skeletal classes and to verify the possibility of clinical application of sella turcicain skeletal maturity estimation.Materials and Methods: The study sample composed of (140) Iraqi adolescent subjects aged 10-16 years (91 females,49 males); every subject had true lateral cephalometric radiograph. The sample was subjected to 2 classifications:the 1st included three skeletal classes according to ANB angle, and the 2nd included accelerative and decelerativegroups according to maturity indicators of cervical vertebrae seen radiographically. In each classification, sella sizewas measured using three linear measurements (S.length, S.depth, and S. diameter).Results: Most of sella turcica measurements were not different statistically among the skeletal classes, and thatspecific sella turcica linear measurements can not be obtained for each specific skeletal class throughout thepubertal period. Normal sella was the predominant over the other morphological aberrations in both classificationsystems, while these morphologies occurred more frequently in class II and III. Sella depth and diameter weresignificantly higher in the decelerative than accelerative group, while non significant difference was foundconcerning sella shapes between the two groups.Conclusions: It was concluded that Sella depth and sella diameter measurements can be utilized clinically forpubertal growth phase determination, while sella morphology can not be diagnostic for the accelerative anddecelerative pubertal growth phases
