Obstructive sleep apnea (OSA) is part of the sleep-disordered breathing spectrum. Its prevalence in children is 1-5%, and it can have negative consequences at the cardiovascular, cognitive as well as behavioral levels. In children, the first-line treatment is adenotonsillectomy. However, residual obstructive events can persist as the success rate of surgery reaches only 49% in non-obese children. Residual OSA may be explained by multiple sites of obstruction, found in 20-85% children concerned by persistent OSA. Indeed, the tongue appears among one possible primary sites of obstruction. Given the tongue's crucial role in upper-airway patency during sleep, its assessment can inform us about the myofunctional deficits involved in sleep-disordered breathing. The primary objective of the present study is to assess tongue motor functions in children with sleep-disordered breathing and to compare them to those of healthy children (data collected in a current study (TMAC) conducted at UCLouvain, Belgium; NCT06166680), in order to document possible myofunctional deficits in children with OSA. The hypothesis is that tongue motor functions will be lower in children with sleep-disordered breathing.

The following items will be assessed: 1. Tongue peak pressure during 3 seconds of tongue protrusion 2. Tongue peak pressure (i.e., the maximal pressure - Pmax - exerted against the IOPI bulb) during 3 seconds of tongue elevation 3. Tongue pressure (in kPa) exerted against the IOPI (Iowa Oral Performance Instrument) bulb while swallowing
Patients will undergo full-night polysomnography (including the JAWAC system to record mandibular movements) in the sleep unit of Hôpital Femme-Mère-Enfant (Bron, France) to explore OSA.
The following questionnaires will be filled out: * OSA-18 * Pediatric Sleep Questionnaire (PSQ) * Spruyt \& Gozal * Sleep Disturbance Scale for Children * Abreu et al.'s questionnaire
The following questionnaires will be filled out: * Epworth Sleepiness Scale * Conners
The following measures will be collected via the Quick Tongue-Tie Assessment tool: 1. Maximal mouth opening 2. Maximal mouth opening with tongue to palate
The following variables will be collected during a clinical examination: 1. Age 2. Sex 3. Weight 4. Height 5. BMI 6. Friedman score 7. Mallampati score 8. Medical history
Bucco-Linguo-Facial Motor Skills will be assessed through the test "Motricité Bucco-Linguo-Faciale" (MBLF).

Tongue peak pressure during protrusion
Tongue peak pressure during protrusion will be measured using the IOPI (Iowa Oral Performance Instrument) device. Higher tongue pressure is considered a better outcome.
Time frame: Day 1
Tongue peak pressure during elevation and swallowing
Tongue peak pressure during elevation and swallowing movements will be measured using the IOPI (Iowa Oral Performance Instrument) device. Higher tongue pressure is considered a better outcome.
Time frame: Day 1
Tongue mobility restriction
Assessed through the ratio between maximal mouth opening and maximal mouth opening with tongue to palate, measured using the Quick Tongue-Tie Assessment tool. Higher values are considered a better outcome.
Time frame: Day 1
Orofacial praxis
Orofacial praxis will be assessed through the Motricité Bucco-Linguo-Faciale (MBLF) test, which ranges from 0 to 111. Higher scores indicate a better outcome.
