In the longest episode in ASAP Pathway history 😄,  Dr. Stacy Becker welcomes back two highly respected guests: Dr. David McIntosh, an Australian ENT surgeon, and Dr. Bill Harrell, a board-certified orthodontist and dental sleep medicine provider. Together, they explore why the future of pediatric airway and sleep health depends on collaboration, better education, and a willingness to challenge long-standing professional paradigms. David and Bill share the story behind their partnership and the creation of the Airway Breathing Academy, an educational resource designed to help both parents and healthcare professionals navigate the complicated—and often contradictory—world of airway health.But this conversation goes much deeper.We discuss the relationship between nasal breathing, craniofacial growth, mouth breathing, sleep-disordered breathing, and orthodontic development. We challenge the idea that expansion alone can resolve every airway concern, examine the importance of evaluating tonsils and adenoids, and explore what CBCT imaging can—and cannot—tell us about a patient's airway.
We also dive into the updated American Association of Orthodontists white paper, the interpretation of emerging research, and the dangers of oversimplifying complicated healthcare decisions on social media. David shares the moments that transformed his understanding of dentistry and orthodontics, while Bill explains why orthodontic education must look beyond tooth alignment to consider the nasal-maxillary complex and the bigger picture of function.
One of the most important messages from this conversation? Mouth breathing is a symptom, not a diagnosis. And expansion is not a substitute for a comprehensive airway evaluation. We also discuss why some children have enlarged tonsils and adenoids, how clinicians can better communicate with families, and why debating which problem came first shouldn't delay helping the child in front of us. Because sometimes a child has two problems—and needs two solutions. Different specialties. Shared knowledge. One team working toward better outcomes for children.

LEARNINGS:💡
1. Airway health requires collaboration. ENTs, orthodontists, dentists, and other healthcare professionals must understand one another's roles to provide comprehensive care.
2. Information is not the same as knowledge. Social media can raise awareness, but oversimplified or inaccurate claims can leave parents confused about treatment options.
3. Mouth breathing is a symptom, not a diagnosis. Identifying why a child is mouth breathing is essential before recommending treatment.
4. Expansion is not a substitute for ENT care. Orthodontic expansion may address certain structural concerns, but it does not automatically resolve enlarged tonsils, adenoids, or other nasal obstructions.
5. Craniofacial development and nasal breathing are connected. Understanding the nasal-maxillary complex can help clinicians recognize concerns that extend beyond tooth alignment.
6. CBCT provides anatomical information, not a sleep diagnosis. Three-dimensional imaging can reveal structural findings, but a static scan cannot establish how the airway behaves during sleep.
7. Screening tools have limitations. Questionnaires, imaging measurements, and sleep-study metrics must be interpreted appropriately rather than treated as interchangeable measures of severity.
8. Enlarged tonsils and adenoids are more complicated than they appear. David discusses how immune responses, infections, and individual biological differences may contribute to lymphoid tissue enlargement.
9. Don't let debates about cause and effect delay care. A child can have both an airway problem and a craniofacial problem, and each deserves an appropriate evaluation.
10. Education empowers better decisions. The Airway Breathing Academy aims to give parents and professionals a more reliable starting point for understanding airway concerns and seeking coordinated care.
