Sella turcica morphology and dimensions in cleft subjects.

Abstract Objectives: Evaluate sella turcica morphology, calculate its size in cleft subjects, and compare it with noncleft subjects. Materials: Lateral cephalometric radiographs of 95 cleft and 190 noncleft individuals. Radiographs were divided into two groups by age: 11 to 14 years of age, 15 years and above. Main Outcome Measures: The morphology of the sella turcica was categorized into six shapes; whereas, the size of the sella turcica was measured in terms of length, depth, and diameter in millimeters. Results: The sella turcica was abnormal in shape in the majority of cleft subjects when compared with noncleft subjects (p  =  .0000), more so in subjects with unilateral cleft lip and palate and bilateral cleft lip and palate (p  =  .0000, p  =  .020, respectively). Depth of sella turcica was smaller in unilateral cleft lip and palate subjects (p  =  .037). A smaller sella turcica size (length, depth, diameter) was evident in cleft subjects as compared with noncleft subjects (p  =  .037, p  =  .004, p ...
