About this trial
Myofunctional therapy has been shown to be effectively reduce symptoms of paediatric obstructive sleep apnea, usually performed after adenotonsillectomy.
This study aims to evaluate the effectiveness of Passive Oral Myofunctional Reeducation (using a flexible oral appliance) compared to nasal hygiene alone (control group), in a population of children scheduled for adenotonsillectomy.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
present signs of obstructive sleep apnea: snoring, apnea / respiratory pauses audible by the entourage (objectivized by a score, to the Pediatric Sleep Questionnaire (PSQ) , greater than or equal to 0.33- This questionnaire comprises twenty-two Questions and has a good sensitivity (83%) and specificity (87%) in screening for pediatric sleep apnea.
be programmed for adenoidectomy, tonsillectomy or adeno-tonsillectomy within 3 months (or more).
Disqualifiers
present with a craniofacial syndrome nor a severe medical condition with complex medical management,
present with an abnormality of the neuromuscular tone (such as Duchenne myopathy or cerebral palsy)
receive orthodontic therapy during the study
have a class III malocclusion (mandibular prognathy type), for which a propulsion oral appliance is contraindicated because it may aggravate mandibular prominence. Maxillary deficiency is not a exclusion criterion.

Treatment groups
Trial outcomes
Primary outcomes
Sleep Parameters Changes : Respiratory Events Index per hour (REI) and Obstructive REI
Full Night Polygraph using an ambulatory device Type III (cardio-respiratory); measurement of the index of apnea and hypopnea/ in relation to total sleep time, according the American Association of Sleep Medicine (AASM) recommandations for children.
Sleep Parameters Changes : Oxygen desaturation index (ODI)
Full Night Polygraph using an ambulatory device Type III (cardio-respiratory); measurement of the index of oxygen desaturation per hour/ in relation to total sleep time, according the American Association of Sleep Medicine (AASM) recommandations for children (oximetry).
Sleep Parameters Changes : Flow Limitation index
Full Night Polygraph using an ambulatory device Type III (cardio-respiratory); measurement of flow limitations per hour , in relation to total sleep time, according the American Association of Sleep Medicine (AASM) recommandations for children (nasal canula or thermistance).
