Ep.72, Beyond AHI: What Actually Drives Pediatric Growth and Development, Dr. Sandra Kahn
ASAP Pathway: THE PODCASTShow Notes
🎙️In this episode of ASAP Pathway, Dr. Stacy sits down with orthodontist, researcher, and inventor Dr. Sandra Kahn to explore the deeper connection between sleep architecture, craniofacial growth, and long-term health in children. Drawing from her personal journey as a mother and clinician, Dr. Kahn shares how her own children’s challenges led her beyond traditional orthodontics and into the root causes of growth dysfunction—nasal breathing, oral posture, and most critically, deep sleep. Together, they discuss why early intervention alone isn’t always sustainable without maintenance, how nitric oxide and nasal breathing impact brain “cleaning” during stage 3 sleep, and why promoting health through proper resting posture may matter more than treating symptoms during the day. They also unpack the concept of the “invisible swallow,” the role of negative intraoral pressure during sleep, and how environmental—not genetic—factors may drive malocclusion and jaw shrinkage. Finally, the conversation turns toward the emotional realities for families navigating airway care, reminding parents that while form and function matter, preserving family connection and reducing overwhelm is equally essential.

🧠 Key Learnings Deep (stage 3 non-REM) sleep is when growth hormone release and brain “cleaning” occur—making sleep architecture critical for pediatric growth and emotional regulation. Proper nasal breathing and relaxed oral resting posture during sleep may influence craniofacial development more than daytime behaviors alone. Nitric oxide’s bioavailability, not just its production, is influenced by nasal airflow dynamics and may affect vascular dilation and glymphatic drainage during sleep. Early orthodontic or ENT interventions can improve anatomy but may not be sustainable without functional maintenance (“rehab”) of resting oral posture. Malocclusion and jaw shrinkage may be environmentally driven, emphasizing the importance of early-life conditions over genetics alone. Teaching a relaxed “invisible swallow” (maintaining minimal negative intraoral pressure) may help support effortless resting posture during sleep. The first 1000 days—from conception through early childhood—represent a key developmental window for establishing healthy breathing and swallowing patterns. Over-focusing on treatment can create stress within families; promoting health through simple, consistent conditions may be more sustainable than aggressive intervention. Preserving parent-child relationships during care is essential—family bond disruption can have lasting emotional consequences.

What if forward head posture, chronic neck pain, morning headaches—or even the way someone sleeps—isn't simply a musculoskeletal problem? What if the body is compensating because it's trying to breathe? In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with chiropractor Dr. Kameron Smith to explore the connection between airway health, sleep, posture, pain and chiropractic care.Kameron's interest in airway began while performing Department of Transportation physicals and recognizing how many drivers were at risk for sleep apnea. Then it became personal. Despite being young, fit and not fitting the stereotypical sleep apnea patient, Kameron was experiencing fatigue, morning headaches and concerning nighttime oxygen readings. His own diagnosis changed the way he began looking at his patients—and eventually his own daughter.Together, Dr. Stacy and Kameron discuss how forward head posture, neck tension, mouth breathing and unusual sleep positions may sometimes be clues that the body is compensating to breathe. They also explore pediatric airway screening, craniofacial growth and development, and why simply correcting posture may miss the bigger question:Why is the body compensating in the first place? Most importantly, this conversation is a call for greater collaboration between dentists, chiropractors and other airway-focused providers. Because sometimes the posture isn't the problem. It's the clue.
What if some of the most powerful tools for healing are already inside your own body? In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with Dr. Matt Bayes, a primary care sports medicine physician, non-surgical orthopedist, and regenerative medicine doctor whose work focuses on orthobiologics—the use of a patient’s own cells to support healing and recovery. Dr. Bayes breaks down PRP (platelet-rich plasma), stem cells, bone marrow aspiration, adipose-derived cells, and ultrasound-guided regenerative procedures in language patients and healthcare providers can understand. He explains how platelets act as important messengers in the body’s healing process, how stem cells participate in tissue repair, and how these therapies may be used for certain ligament, tendon, cartilage, joint, and musculoskeletal injuries. But this conversation is also about knowing when regenerative medicine is—and isn’t—the right answer. Dr. Bayes and Dr. Stacy discuss the importance of diagnosis and case selection, including situations where surgery remains the appropriate treatment. The discussion also bridges medicine and dentistry as Dr. Stacy explores the growing role of regenerative approaches such as PRF in TMJ care and considers how her own experience with regenerative medicine is influencing the direction of her dental practice. And beneath all of it is a wonderfully simple message: Movement is medicine. Curiosity makes us better clinicians. Collaboration improves patient care. And sometimes the best way forward is to work with the healing capacity the body already possesses.
In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with Dr. Pedro Cuartas, founder of the Collaborative Airway Management Summit (CAMS) and Clinical Director of South Louisiana Dental Sleep Medicine, for a conversation about what may be one of the biggest missing pieces in airway healthcare: collaboration.
In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with dental sleep medicine expert Crystal May, Vice President of Dental Sleep Medicine at Happy Sleep, for a wide-ranging conversation about why sleep screening needs to become a routine part of healthcare—and why dentistry may be one of the best places to start.
Season Six of the ASAP Pathway Podcast starts with the three ASAP Pathway co-founders together at the table: Drs. Stacy, Tracey, and Michelle—and this one gets personal. What actually happens to women’s sleep when hormones begin changing? Why does obstructive sleep apnea become much more prevalent in women around midlife? Why can women feel exhausted, foggy, anxious, achy, restless and simply say, “I don’t feel like myself anymore”—yet still have a sleep study that doesn’t look particularly alarming? And what do estrogen, progesterone, cortisol, jaw pain, clenching, TMD, airway anatomy and even heart health have to do with one another? The founders dive into the changing conversation around perimenopause and menopause, including why traditional sleep apnea screening may fail to identify many women. They discuss the limitations of relying only on oxygen desaturations and AHI, and explain RERAs—respiratory effort-related arousals—events that may repeatedly fragment sleep without necessarily meeting the traditional definition of apnea.
