Management of Obstructive Sleep Apnea (OSA) in Children and Maxillary and Mandibular Development

Not Applicable
Completed
Conditions
Obstructive Sleep Apnea Syndrome
Interventions
Device: Rapid palatal expansion
Device: MGA™ system
Device: Yoobreath™ system
Registration Number
NCT03267927
Lead Sponsor
Rennes University Hospital
Brief Summary

Assessment of the association of maxillary expansion using a rapid palatal expansion, use of a mandibular advancement appliance (MGA™) and of a device allowing sleep in a semi-seated position (Yoobreath™) in patients with Obstructive Sleep Apnea (OAS). MGA™ and YooBreath™ constitute the Yookid system™.

Detailed Description

Obstructive Sleep Apnea syndrome (OSA) shows a 10% morbidity rate in children with a higher rate between the ages of 3 and 5. Generally speaking, its prevalence is underestimated. Furthermore, detecting OSA remains difficult due to its particular physiopathology. The decrease in nasopharyngeal airway dimensions is the most common etiology. This decrease is related to soft tissues as well as maxillomandibular abnormalities. The aim of the study is to show that reducing sleep apnea in children remains possible when inducing rapid palatal expansion and mandibular advancement using the Yookid™ system. The Yookid™ system associates a mandibular advancement appliance and repositioning of the patient during sleep.
