Abstract

|
|
Purpose: The purpose of this study was to investigate variations in velar shape according to age, sex, and race using magnetic resonance imaging (MRI).
Materials and Methods: The study sample consisted of 170 participants (85 children, 85 adults) between 4 and 34 years of age. Velar morphology was visually classified using midsagittal MRI scans for each participant by 2 independent raters. Inter- and intra-rater reliability was assessed. Statistical analyses were performed to identify correlations of velar shape with sex, age, and race.
Results: The most frequent velar shape was ¡°butt¡± for both adults (41%) and children (58%) in this study. The least common shapes for adults were ¡°leaf¡± and ¡°S.¡± The children did not exhibit any ¡°leaf¡± or ¡°straight¡± velar shapes. A statistically significant difference was noted for age with respect to velar shape (P=0.014). Sex and race were found to have no significant impact on velar shape in this study.
Conclusion: When using MRI to evaluate velar morphology, the ¡°butt¡± shape was most common in both children and adults. Velar shape varied significantly with age, while race and sex did not have a significant impact.
