Co-Director, Hello Smile HK

Dr. Stanley Liu is an internationally recognized maxillofacial and sleep surgeon whose career has been devoted to improving breathing, facial development, and sleep. He serves as Chair of Oral & Maxillofacial Surgery at Nova Southeastern University, and previously was Director of the Stanford Sleep Surgery Fellowship and Associate Professor of Otolaryngology at the Stanford University School of Medicine.
 
A global educator in sleep-disordered breathing, Dr. Liu has played a major role in advancing pediatric sleep health worldwide. He has lectured for the International Pediatric Sleep Association (IPSA), the International Association of Paediatric Dentistry (IAPD), and taught for years in the Tufts Pediatric Dental Sleep Mini-Residency. He now teaches in the Pediatric Airway Mastery Course directed by Dr. Audrey Yoon and in pediatric sleep medicine through Airway Health Solutions with Dr. Umakanth Katwa.
 
Dr. Liu is a frequent invited speaker at major international meetings, including the ADA Children’s Health Symposium, and has served as a keynote speaker at the World Sleep Congress. His teaching highlights the essential links between facial growth, airway physiology, and pediatric sleep health. As he notes, sleep surgery is about “restoring missed milestones in facial and airway growth.”
 
With 156 peer-reviewed publications, his research spans airway development, sleep-disordered breathing, maxillary expansion, precision diagnostics, and the neurophysiology of sleep—consistently emphasizing early recognition of airway underdevelopment and the unified relationship among breathing, growth, behavior, and sleep.
 
As Co-Director of Hello Smile HK, Dr. Liu advances the NGO’s mission of early detection, family education, and integrated care for pediatric sleep-breathing disorders. He believes that healthy sleep breathing is the gateway to wellness and is committed to making airway-centered care accessible to every child.
