2022 MASO CE Seminar

“Don’t Ignore the Snore: Current OSA Research and the Orthodontist’s Role”

March 11, Princeton, NJ

5.5 CE Credits Available!

Thank you for attending!

About The Program

Join MASO and three Stanford University researchers for an in-depth study of obstructive sleep apnea, airway development, and related topics.

“The Role of Orthodontic Intervention in Sleep Disordered Breathing,” Dr. Audrey Yoon, Smile Design & Beyond

Most current orthodontic treatments have focused on changing the anatomy to establish a beautiful smile and occlusion. However, we have not quite understood the mechanisms of how anatomical changes affect the orofacial function and the pathophysiology of sleep-disordered breathing.  Dr. Yoon will show her extensive researches for a better understanding of the relationship between anatomical factors and the physiology of sleep-disordered breathing.  Dr. Yoon will discuss the early identification of the etiology and understanding the pathophysiology to prevent diseases. She will also discuss the orthodontic approach for modifying orofacial growth and development with the newest technique to achieve ideal skeletal structures and to reprogram orofacial muscle functions.  


“Sleep, Breathing, Tongue-Tie, and Maxillofacial Development,” Dr. Soroush Zaghi, The Breathe Institute

Orthodontists are in a unique position to screen and monitor for myofunctional and upper airway function disorders that may impact long-term craniofacial and airway development. Chronic mouth breathing and low tongue posture in actively growing children is associated with palatal growth restriction, alterations of craniofacial development, altered head posture, attention issues, poor school performance, relapse of orthodontic treatment, and increased risk for obstructive-sleep apnea later in life.  This presentation will provide an overview of the spectrum of sleep-related breathing disorders ranging from mouth breathing to upper airway resistance syndrome, snoring, and obstructive sleep apnea in pediatric populations. The emphasis of the presentation will be on understanding how addressing sleep and breathing issues early on can make a huge impact on the overall health and quality of life of their patients. Participants will learn to not only screening and refer patients with symptoms of mouth breathing and myofunctional disorders but more importantly to actively participate in management and prevention through encouragement and support of nasal breathing and tongue posture with myofunctional therapy, lingual frenuloplasty, and dental orthodontic treatments.


“Sleep Surgery: Restoring Bite, Breathing and Beauty,” Dr. Stanley Yung Liu, Stanford University

Restoring sleep airway health is the gateway to wellness. From the earliest days of life, cognition, facial dysmorphism, and systemic conditions are negatively impacted by sleep-disordered breathing. This lecture will focus on the missed milestones in one’s growth and development, and how they negatively affect one’s wellness. More importantly, a contemporary and comprehensive approach to addreay practical guidelines and screening tools to help identify early signs of slessing the missed milestones via orthodontic-surgical collaboration will be discussed. Learners will also take awep-disordered breathing at all stages of human growth and development.
Finally, the most up-to-date surgical interventions will be discussed in relation to the core theme of this lecture.

After this course, the attending doctor should be able to:

(1) Understand how specific orthodontic protocols can participate in the resolution of obstuctive sleep apnea

(2) Understand the relationship between anatomical factor and physiology of sleep-disordered breathing

(3) Understand specific orthodontic treatment options that can be offered from infant to adult with persistent obsturctive sleep apnea

(4) Define why early diagnosis and treatment of sleep disordered breathing is imperative for children’s growth and development


Course Objectives “Sleep, Breathing, Tongue-Tie, and Maxillofacial Development,”

After this course, the attending doctor should be able to:

(1) To appreciate the impact of sleep-related breathing disorders on pediatric populations.

(2) Be able to screen for and identify the clinical signs of mouth breathing, tongue-tie, and sleep-disordered breathing among patients in your practice.

(3) Appreciate the impact of restricted tongue mobility on mouth breathing, snoring, and maxillofacial development, as well as neck tension, pain, postural dysfunction, and fascial restrictions.


Course Objectives “Sleep Surgery: Restoring Bite, Breathing and Beauty,”

After this course, the attending doctor should be able to:

(1) Learn about the latest evidence-based comprehensive approach to the care of patients with sleep disordered breathing, from dental to medical and surgical

(2) Identify the missed milestones during growth and development where orthodontists play critical roles in the prevention of sleep-disordered breathing

(3) Incorporate technology to orthodontic-surgical collaboration to address bite (occlusion), breathing (OSA), and beauty (facial balance) in adults

(4) Learn about the evolution of maxillary expansion from the unmet needs of adult nasal breathing, both in awake and asleep states

The Speakers

Dr. Audrey Yoon

Dr. Audrey Yoon is a dual-trained orthodontist and pediatric dentist.  She completed her orthodontic and pediatric residencies at UCLA.  She also earned her Doctor of dental surgery and master of science degree, completing extensive research in Obstructive Sleep Apnea at UCLA.  She is an adjunct assistant professor at Stanford University Sleep Medicine an adjunct assistant professor in orthodontics at the University of Pacific and a co-director of the pediatric dental sleep mini-residency program at Tufts University dental sleep medicine. 

She has introduced a pioneering technique, performing distraction osteogenesis maxillary expansion for the treatment of OSA, and has authored chapters on this subject in many leading textbooks. She has created an interdisciplinary rotation program between Stanford Sleep Surgery and the University of Pacific orthodontic residency program and is co-founder of pediatric dental sleep medicine residency at Tufts University.
