The tongue is a central anatomical contributor to upper airway collapsibility; however, its biomechanical properties have been investigated almost exclusively in adult populations, leaving a critical gap in knowledge regarding younger individuals.\n\nThis study aims to assess tongue biomechanical and echographic characteristics using quantitative ultrasound modalities - shear-wave elastography (SWE), acoustic attenuation, and echo intensity - in adolescents aged 12 to 18 years with obesity and obstructive sleep disorders. The study adopts a mixed design combining (1) an observational cross-sectional comparison between participants with obesity and OSDB and age- and sex-matched healthy controls at baseline, and (2) a prospective longitudinal cohort component evaluating changes in tongue ultrasound characteristics over the course of a 30-week multidisciplinary inpatient weight-loss program delivered as standard care at the Zeepreventorium (De Haan, Belgium). An additionnal methodological objective consists in determining intra-rater and inter-rater reliability of the ultrasound acquisition protocol providing a reproducible framework for future studies.",[28,29,30],"Obesity & Overweight Sleep","Obstructive Sleep Disordered Breathing","Pediatric Obesity","NOT_YET_RECRUITING","2026-05-21",{"date":34,"type":35},"2026-05-29","ACTUAL",{"date":37,"type":22},"2026-09",{"date":39,"type":22},"2027-12-31",{"name":41,"class":42},"Vrije Universiteit Brussel","OTHER",2]
