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",{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":48,"acronym":49,"eligibilityCriteria":50,"healthyVolunteers":11,"sex":17,"minAge":51,"maxAge":52,"enrollmentInfo":53,"targetDuration":4,"studyType":55,"phases":4,"briefSummary":56,"conditions":57,"keywords":58,"overallStatus":65,"whyStopped":4,"lastUpdateSubmitDate":66,"lastUpdatePostDateStruct":67,"startDateStruct":69,"completionDateStruct":71,"leadSponsor":73,"locationsCount":75},"100576957","prediction-of-tongue-base-obstruction-during-sleep-100576957","NCT06792045","Prediction of Tongue Base Obstruction During Sleep","Tongue Motor Functions Assessment as a Screening Tool for Obstructive Sleep Disordered Breathing in Children","PTOS","Inclusion Criteria:\n\n* Age between 6 and 17 years old\n* Medical diagnosis of obstructive sleep-disordered breathing requiring surgical removal of tonsils (partial or total) and\u002For adenoids\n* Positive Pediatric Sleep Questionnaire (8 or more positive responses)\n* Eligibility for surgical intervention\n\nExclusion Criteria:\n\n* Neurological, cardiac, or respiratory comorbidity other than obstructive sleep-disordered breathing\n* Previous surgery of the upper airway or oral cavity\n* History of or current head or neck cancer\n* Cranial, upper airway, or oral cavity malformation\n* Contraindication to performing endoscopy","6 Years","17 Years",{"count":54,"type":22},48,"OBSERVATIONAL","This study investigates the hypothesis that, in children, tongue motor functions can predict both the anatomical site and the degree of upper airway obstruction contributing to obstructive sleep-disordered breathing.",[29],[59,60,61,62,63,64],"obstructive sleep disordered breathing","pediatrics","sleep","obstructive sleep apnea","snoring","tongue","RECRUITING","2026-04-28",{"date":68,"type":35},"2026-05-04",{"date":70,"type":35},"2025-08-22",{"date":72,"type":22},"2027-10",{"name":74,"class":42},"Université Catholique de Louvain",1]
