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

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™.

About this study

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.

Treatment and study plan

Rapid palatal expansion

Device

MGA™ system

Device

Use of a mandibular advancement Appliance during the night from day 60 to day 180 (end of treatment from day 120 if Angle Class I is obtained)

Yoobreath™ system
