Characterization of the Tongue in Children With Obstructive Sleep-disordered Breathing
The tongue plays a key role in maintaining upper airway patency during sleep, mainly through the genioglossus, the principal pharyngeal dilator muscle. Its dysfunction may be linked to the development of obstructive sleep-disordered breathing (oSDB), a condition affecting more than one in ten children and associated with cardiovascular and cognitive consequences. Although adenotonsillectomy remains the treatment of choice, it fails in a substantial proportion of cases because of persistent obstruction at other sites, the tongue base being involved in one third of these cases. Therefore, a better characterization of the tongue in children with oSDB is needed, since the extent to which its structure and function contribute to upper airway obstruction in this population remains largely unknown.
Our team has established the reproducibility of tongue function measurements in healthy children and is currently building a reference database. What is still lacking is an assessment of tongue structure and function in children with oSDB. Such data would allow comparison with healthy children, thereby improving the understanding of oSDB pathophysiology and informing clinical management.
Primary objective: To describe tongue structure and function in children with oSDB.
Secondary objective: To compare tongue structure and function between children with oSDB and healthy children, using data from a previous study conducted in healthy children (TMAC study, UCLouvain).

Popis opatření |
Časové okno |

|
Tongue morphology assessment
Časové okno: At enrollment, during the single study visit (Day 1)
|
Submental ultrasound in frontal and sagittal plane, to assess the thickness of tongue muscles (cm) |
At enrollment, during the single study visit (Day 1)
|
|
Tongue frenulum assessment
Časové okno: At enrollment, during the single study visit (Day 1)
|
Tongue range of motion ratio, reflecting the restriction imposed by the lingual frenulum. It is computed as the maximal mouth opening with the tongue tip held at the incisive papilla (mm) divided by the maximal mouth opening (mm). |
At enrollment, during the single study visit (Day 1)
|
|
Tongue mobility score
Časové okno: At enrollment, during the single study visit (Day 1)
|
Motricité Bucco-Linguo-Faciale (MBLF) test, where several movements are scored between 0 and 3 regarding muscular contraction or symmetry. |
At enrollment, during the single study visit (Day 1)
|
|
Obstructive apnea-hypopnea index
Časové okno: At enrollment, during the single study visit (Day 1)
|
Number of obstructive apneas and hypopneas per hour of sleep (events/hour) assessed through polysomnography |
At enrollment, during the single study visit (Day 1)
|
|
Breathing pattern questionnaire
Časové okno: At enrollment, during the single study visit (Day 1)
|
Mouth breathing questionnaire from Abreu et al., considered positive if two major items, or one major and two minor items, are answered "yes" |
At enrollment, during the single study visit (Day 1)
|
|
Quality of life questionnaire
Časové okno: At enrollment, during the single study visit (Day 1)
|
PedsQL questionnaire (Pediatric Quality of Life Inventory), divided into parent report and child self-report questionnaires, with several items scored from 0 to 4. Higher scores indicate more problems related to the quality of life. |
At enrollment, during the single study visit (Day 1)
|
|
Sleep quality questionnaire
Časové okno: At enrollment, during the single study visit (Day 1)
|
The Pediatric Sleep Questionnaire will be administered to parents. Items are answered "yes", "no", or "I don't know", and higher scores indicate more signs of obstructive sleep-disordered breathing. |
At enrollment, during the single study visit (Day 1)
|
|
Sleep-related quality of life questionnaire
Časové okno: At enrollment, during the single study visit (Day 1)
|
The Obstructive Sleep Apnea-18 (OSA-18) questionnaire will be administered to parents. Higher scores indicate a greater impact of sleep-disordered breathing on quality of life. |
At enrollment, during the single study visit (Day 1)
