A familial case study exploring craniofacial, velopharyngeal, and speech variations in pierre robin sequence

Abstract

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.
