What is Myosa® for Children

Breathing and Disordered Sleep (BDS) issues begin to develop in early childhood and when left untreated, result in a range of disorders. BDS can progress to Obstructive Sleep Apnoea (OSA) in children, which can have detrimental consequences on their behaviour, learning, growth and development. These health problems will persist into a patient’s adult life and continue to worsen.

Modern research has indicated that a large number of the paediatric population has some form of BDS15,16 and the likelihood that these numbers are underestimated is high.

As the evidence begins to mount within the literature from multiple different disciplines, attention must be turned to a treatment protocol which is easily implemented and capable of dealing with the treatment demand. The dental practitioner plays a central role in treating and coordinating the management of these patients.

How the Myosa® for Kids Works

MRC's innovative paediatric Myosa® appliances for Juniors and Kids treats BDS by addressing causitive factors such as abberant myofunctional habits and breathing dysfunction.

The appliances are designed to open the airway, improve tongue posture, establish a lip seal and aid in the transition to nasal breathing, while allowing for mouth breathing to take place. The appliances have a 5mm base and move the mandible forward, which opens the upper airway.

When combined with the Myosa® treatment protocols, the appliances are easily implemented for and have been shown to be effective in the management and treatment of children with BDS,17 while also allowing for a seamless transition into MRC's myofunctional orthodontic treatment system - Myobrace®.

In order to maximise the potential of adequate craniofacial and airway development, the ultimate goal should be the establishment of continuous nasal breathing.14

Myosa® for children appliances treat the myofunctional habits contributing to Breathing and Disordered Sleep. This can be achieved by encouraging correct nasal breathing while allowing some mouth breathing for comfort. 5mm base opens the airway when in place.

Mouth breathing is abnormal and is one of the causes of Breathing and Disordered Sleep (BDS) problems.

If a child breathes through their mouth, the jaws will not develop forwards. Adults who have BDS will usually have underdeveloped jaws, which cause the tongue and lower jaw to restrict the airway. Therefore, it is important to encourage forward growth and re-learn to breathe correctly, through the nose at all times so the lower jaw and tongue are held forward and the airway is kept open.
