The purpose of this study was to establish normative parameters regarding the total distance of hyoid bone displacement following discrete bolus sizes of puree and liquid in 3 and 4 year old children. Establishing normative parameters for hyoid bone displacement in preschool-aged children will assist in the safe and accurate diagnoses of pediatric dysphagia. Twenty-nine typically developing children were assessed via an ultrasonic procedure. Following the capture of a swallow, precise hyoid bone measurements were obtained through frame-by-frame analysis. Results indicated small variability in hyoid bone displacement across all bolus sizes and consistencies. A marginally significant interaction effect was present between bolus size and consistency regardless of age or gender differences; specifically, there was a strong interaction effect at 0.5 cc. Furthermore, the results demonstrated a significant gender effect characterized by greater hyoid bone displacement in female subjects.
