Doppler sonar analysis of swallowing sounds in normal pediatric individuals.

Unlabelled: Among the methods for assessing swallowing sounds - videofluoroscopy modified barium study, fiberoptic swallowing endoscopy, neck auscultation through a microphone, accelerometer and, more recently, the Doppler sonar - we have chosen the latter.

Aim: to analyze swallowing sounds by cervical auscultation using Doppler sonar, in a population between 2 and 15 years without oro-pharyngeal dysfunction.

Study Design: cross-sectional historical cohort.
