Tongue movement tests to predict airway blockage during sleep in children

Tongue Motor Functions Assessment as a Screening Tool for Obstructive Sleep Disordered Breathing in Children

Observational Université Catholique de Louvain · NCT06792045

This project will test whether simple tongue movement tests can predict where and how much a child's airway closes during sleep for children with obstructive sleep-disordered breathing who are scheduled for tonsil or adenoid removal.

What this trial studies

This observational study enrolls children aged 6–17 with diagnosed obstructive sleep-disordered breathing who are scheduled for tonsil and/or adenoid removal. At a pre-surgical visit a physiotherapist will perform standardized tongue motor function tests and ENT clinicians will perform routine assessments. Participants will undergo drug-induced sleep endoscopy (DISE) prior to surgery to directly visualize the site and degree of airway obstruction. Researchers will compare tongue motor measurements with DISE findings to see if tongue function predicts tongue-base obstruction.

Who should consider this trial

Good fit: Children aged 6–17 with obstructive sleep-disordered breathing who are eligible for tonsil and/or adenoid surgery and who have a positive Pediatric Sleep Questionnaire are ideal candidates.

Not a fit: Children with neurological, cardiac, or respiratory comorbidities, prior upper airway surgery, craniofacial malformations, or contraindications to endoscopy are unlikely to benefit from or be eligible for this project.

Why it matters

Potential benefit: If successful, clinicians could use simple, noninvasive tongue tests to better identify children whose airway collapse is driven by the tongue base, improving treatment selection and potentially avoiding unnecessary procedures.

How similar studies have performed: Drug-induced sleep endoscopy is an established diagnostic tool, but using tongue motor function tests to predict tongue-base obstruction in children is relatively novel with limited prior data.
