Morphological variation of the velum in children and adults using magnetic resonance imaging
Kotlarek, Katelyn J.,Haenssler, Abigail E.,Hildebrand, Kori E.,Perry, Jamie L. Korean Academy of Oral and Maxillofacial Radiology 2019 Imaging Science in Dentistry Vol.49 No.2
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.

A descriptive, prospective case study design was used to describe craniofacial, velopharyngeal, and speech measures of three siblings with a family history of Stickler syndrome. Two of the siblings had Pierre Robin sequence and cleft palate. All participants underwent nasometry, perceptual resonance rating, speech sound analysis, and magnetic resonance imaging. The child with a history of compensatory articulation errors showed notable differences in velopharyngeal function and medical history, as well as craniofacial and velopharyngeal dimensions when compared to siblings without a history of these speech errors. Further analysis of velopharyngeal and speech measures should be performed using a larger sample size within this population.
