Among different technology used in oropharyngeal swallowing instrumental evaluation, considering cost-benefit ratio, tongue movement ultrasound stand out as a viable instrument to investigate orofacial functions. This study aims to describe and to define - both qualitatively and quantitatively - ultrasonographic parameters of oropharyngeal swallowing among healthy adults and to verify in what way the variables age group and consistency of food swallowed, as well as respective interactions, might interfere with ultrasonographic parameters. Ultrasonographic evaluations of swallowing were performed (using the DP 6600 portable ultrasound machine, a micro-convex probe connected to a PC, and a Stabilization Headset) in 100 people (divided into four groups: GI - 20 à 30 age, GII - 31 à 40 age, GIII - 41 à 50 age e GIV - 51 à 60 age), using liquids (both free volume and controlled swallow of 5 ml) and pudding-consistent food (controlled swallow of 5 ml). Tongue and hyoid bone movement, used as parameters to qualitative analysis, were adapted from a previous study. During the oropharyngeal swallowing, the presence of five markers was considered. The following parameters were regarded in the quantitative analysis: tongue movement propulsion duration during swallowing, and maximum displacement of the hyoid bone during swallowing peak. Considering qualitative ultrasonographic description, the results pointed that all volunteers presented the same standard tongue posture previous to food reception (phase 1) and containment (phase 2), regardless of food consistency and volume. During the bolus propulsion (phase 3), a wide intersubjective variety of wavelike movements was observed. Concerning maximum displacement of the hyoid bone (phase 4), the ultrasonographic image was analyzed having as reference a 45º angle, that is, for each kind of bolus, we considered displacements equal or under 45º, or above this. Generally, the angle ...
