Sella Turcica Morphology and Dimensions in Cleft Subjects”


Objectives: Evaluate sella turcica morphology and calculate its size in cleft subjects, and to compare it with non-cleft subjects.

Design: Retrospective study.

Setting:  Academic institution, division of Orthodontics, King Saud University,  Riyadh, Saudi Arabia.

Materials: Lateral cephalometric radiographs of 95 cleft and 190 non-cleft individuals. Radiographs were divided into two groups by age; 11-14 years of age, 15 years and above.

Main outcome measures: The morphology of sella turcica was categorized into 6 shapes, while the size of sella turcica was measured in terms of length, depth, and diameter in millimeters.

Results: Sella turcica was abnormal in shape in the majority of cleft subjects when compared with non-cleft subjects (P=0.0001). Depth of sella turcica was smaller in UCLP subjects (P=0.037). A smaller sella turcica size was evident in cleft as compared with non-cleft subjects (P=0.037, P=0.004, P=0.000). Age affected depth and diameter of sella turcica in cleft as compared with the non-cleft group (P=0.001, P=0.007, P=0.0001, P=0.0001, respectively), while length was smaller only in the younger age group (P=0.0001). Sella turcica size was smaller in the younger age group of the non-cleft, and the combined cleft subjects (except length in the non-cleft subjects P=0.062).

Conclusions: Majority of cleft subjects display an abnormal appearance of sella turcica when compared to non-cleft subjects. A smaller depth of sella turcica is associated with UCLP. Sella turcica in cleft are smaller in size than non-cleft subjects. Younger individuals, with or without clefts, display smaller sella turcica size than older ones.
