Myofunctional Therapy for Children With OSA

Hong Kong174 participantsStarted 2025-12-01

Plain-language summary

Myofunctional therapy (MFT) has been proposed as an adjunctive therapy for obstructive sleep apnoea (OSA) in children. Some studies have reported improved sleep parameters and reduced oral breathing after MFT. However, the level of evidence in these studies is limited, with most being case series or case-control studies. There have been only a few randomised controlled trials (RCTs), and these studies have had limitations such as low response rate, short follow-up periods, and the existing evidence does not adequately address the potential clinical benefits and the impact on craniofacial structure. Additionally, there is a lack of evidence regarding the effectiveness of additional measures, such as remote guidance and supervision, in improving treatment outcomes in children. Therefore, there is a need for further research to address these gaps and provide more robust evidence on the efficacy of MFT in children with OSA. The objective of this study is to investigate the efficacy of MFT in children with OSA through a multi-centre randomised controlled trial (RCT). 174 children aged 6-12 years old with OSA will be recruited and randomly assigned to either the intervention or control group. All children will undergo standardised evaluation at baseline and follow-up visits. In the intervention arm, a 24-week myofunctional therapy targeting orofacial MFT, breathing, and postural re-education, with incorporation of telemedicine for remote training and monitoring. In the control arm, children will receive standard care without MFT. The primary outcome measure will be obstructive apnoea hypopnoea index measured by polysomnography. Secondary outcome measures will be the oral breathing pattern, OSA-related symptoms, and quality of life. The treatment effect on outcomes will be examined using a mixed-effects model with an intention-to-treat approach. Subgroup analyses will explore potential effect modification by important participant characteristics, such as OSA severity and compliance. This study will generate evidence-based information regarding the efficacy of MFT in children with OSA and will inform clinical practice.

Inclusion criteria

✓. Children aged 6-12 years, with this age range, children start to have a greater ability to understand and follow instructions, making them more likely to comply and cooperate with the treatment procedures, and at the same time this age range remains a critical and modifiable developmental window when interventions can address underlying orofacial muscle and respiratory muscle dysfunctions and enhance the potential for long-term benefits.
✓. Diagnosed with OSA based on clinical evaluation and polysomnography (oAHI ≥ 1/hour). The clinical evaluation will involve assessing the presence of habitual snoring, which is defined as snoring occurring 3 nights or more per week on average as reported by parents or caregivers, and any of the following features suggestive of SDB such as oral breathing, respiratory pauses, observed apnoeas, or increased work of breathing during sleep. Children with persistent OSA, documented by repeat PSG, can be included after receiving standard treatments (such as adenotonsillectomy treatment).
✓. Informed consent from a parent or a legal guardian.
