A newly published review from Dr Audrey Yoon’s group summarising the current knowledge on paediatric obstructive sleep apnoea.

The paper outlines the multifactorial contributors to paediatric OSA, distinguishing between anatomical and non-anatomical phenotypes, and reviews contemporary treatment approaches aligned with specific craniofacial patterns.

A well-structured and thoughtful synthesis of current knowledge—and a reminder of the importance of continual learning to ensure our clinical decisions remain evidence-based and patient-centred, particularly in airway and functional care.

Just spent the past 4 days on a cadaver surgical course, picking up advanced tips and techniques that will help me treat my patients more holistically and effectively.

Had a lot of fun along the way — and no photos of the cadavers, of course, for privacy reasons! 🦷✨

Could jaw expansion influence adenoid and tonsil size?
I would like to share with you, the progress radiographs of the three patients I saw this week.

These radiographs were taken approximately 12 months apart. None of these children had adenoidectomy or tonsillectomy . ENT collaboration was done from the beginning. Two are still under monitoring. None of the children had any steroid sprays within 1 month of radiographs being taken.

Treatment done was orthopaedic expansion, oromyofunctional therapy and dietary recommendations. None has had any tethered tissue releases yet.

Compliance with diet changes and oromyofunctional therapy were not always 100% but in general was good ( parents have a monthly chart that the sign. The score was on average 80% or above each month)

Age of patients : 7 -9 years of age

What we observed:
🔹 Reduced adenoid size in 2 cases
🔹 Reduced tonsillar size in 1 case

While this is not a controlled study, these findings echo existing research (Yoon et al., 2022; Villa et al., 2007) suggesting adenoids and tonsillar size reduction as one of the benefits of palatal expanders treatment .

Possible mechanisms include:
🌀 Increased nasal volume → less airflow resistance and lymphoid irritation
🫁 Improved nasal breathing → better nitric oxide delivery → fewer allergic/infective triggers
🌬️ Lower inspiratory pressure → less airway collapse and stress on lymphoid tissue

Clinical observation — not conclusion — but worth sharing with those curious about growth, function, and airway health.

I had the pleasure of attending the ASTOT 2025 Symposium this weekend, themed “Collaborative Conversations – Tongue Tie and Other Oral Ties Across the Lifespan.”

It was an enriching experience connecting with healthcare providers from around Australia and around the world, all sharing knowledge and insights on oral restrictions in infants, children, and adults.

A lovely surprise was seeing some of my fellow Indonesians presenting their research—so proud to see their contributions on the international stage!

Every patient has their own journey.

This patient specifically chose a bridge to restore her failing tooth, and she couldn’t be happier with the result!

The after photo was taken immediately after cementation, so you may notice some minor bleeding from where excess cement was removed.

On the first review appointment, this young girl said to me “The first night I wore my aligners, I had the first best sleep ever!”. Her mum commented on how different she has been since she started treatment. She wakes up happy, she is more energetic, and is a completely different child. She has had her older children have orthodontic treatment in the past but she was amazed at how big of a change this time was , with her daughter.

Sometimes children don’t tell you when they don’t sleep well but we can screen them, look at where they are in growth, where they should be in growth , then choose the right appliances and mechanics to bring them back on better growth trajectory.

In my short talk with , I did mention a few key points in the maxilla and mandible where we could influence growth. These were used in planning this case.

Appliance used for this case was Angel Aligner Kids.

Additional points:
- Releases were done in babyhood ( not by me). Her local OMT and I are monitoring her functions. ( 🚩buccal frenae 😅, …. P.S it really helps when you are also OM trained )
- patient has been seeing body worker since young age mainly for hip issues. Body worker commented that their adjustment had been held up longer
- dietitian/ naturopath support from patient’s family friends

This is what myofunctional dentofacial orthodontics can achieve. ( and no, patient did not lose weight. If anything she gained more weight)

Family’s main concern was night time grinding and the increased overlap between upper and lower front teeth.

Mother mentioned that older sibling had extraction and she was not too happy of the outcome.

Treatment time was 12 months.

If you are an member, I also discussed this case in the Thursday Night Live session
