Abstract

Objectives: The purpose of this study was to evaluate and compare size and shape of the
sella in skeletal class II subjects with normodivergent, hypodivergent and hyperdivergent
growth patterns.

Materials/methods: Standardized pre-treatment lateral cephalograms of 90 patients (45
males and 45 females) were selected based on values of five parameters. The sample
consisted of 3 groups (normodivergent, hypodivergent and hyperdivergent) having 30
subjects each. The measurements included width, height, length and width/height (W/H)
ratio. Student's t-test was used to calculate the differences in sella measurements among
males and females of the same group, while one-way analysis of variance was used to
determine the relationship between sella measurements and skeletal pattern. W/H ratio
was used to assess the shape of the sella turcica. Values of W/H ratio were divided into 3
equal ranges: average, horizontally elongated or flat, and vertically elongated shapes. The
shape of the sella turcica in groups was studied with the chi-square test and post-hoc
analysis.

Results: The results showed that the W/H ratio was maximum for hypodivergent and
minimum for the hyperdivergent group. (p = 0.000). The average shape of sella turcica was
most common among all the groups. No significant difference in mean sella turcica length,
width and height was found between the groups. The sella turcica length in males of
hypodivergent group was significantly higher as compared to the females of the same
group (p = 0.038).

Conclusions/implications: Sella turcica shape and dimensions can be used for the future
studies as reference when comparing the same with the skeletal growth pattern.
