Dr. Liu is as an Associate Professor of Otolaryngology, and by courtesy, of Plastic and Reconstructive Surgery at Stanford University School of Medicine. He is director of the Stanford Sleep Surgery Fellowship, and preceptor to the Stanford Oculoplastic Surgery Fellowship. He is a Stanford Biodesign Faculty Fellow Alumnus.After graduating from Stanford University with a degree in Biology, Dr. Liu received medical and dental degrees from the University of California-San Francisco (UCSF). He was a former Howard Hughes Medical Institute (HHMI) Research Scholar and spent a year at the NIH. After oral and maxillofacial surgery residency at UCSF, he completed the Stanford sleep surgery fellowship in 2014 with the Department of Otolaryngology and sleep surgery pioneer Dr. Robert Riley.Dr. Liu practices the full scope of sleep apnea surgery including nasal, palate, tongue base, hypoglossal nerve stimulation, genioglossus advancement, and maxillomandibular advancement (MMA). He introduced adult maxillary expansion (DOME) for OSA with Professor Christian Guilleminault in 2015, and has continued to update the comprehensive sleep surgery protocol at Stanford. He is also routinely referred patients who need complex facial trauma reconstruction and orthognathic surgery.Dr. Liu's active areas of research include clinical phenotyping to optimize sleep surgery outcome, virtual surgical planning for facial skeletal surgery, and neuromodulation of the upper airway. He has given keynote talks nationally and internationally at preeminent conferences across specialties. He has published over 90 scientific articles and medical texts, with original scientific work on sleep surgery.
To “see” the airway: how it collapses during snoring for our patients with obstructive sleep apnea remains a challenge. At Stanford, we started a study using ultrasound imaging to “see” your airway in a non-invasive manner without radiation.An FDA-approved ultrasound device build on artificial intelligence capability (AmCAD UO) is used to see your airway. It is then compared to traditional nasopharyngoscopy (i.e., a flexible tube is inserted into the nose to see the airway). Part of your routine clinic examination.We hope that in the future, ultrasound visualization may become a better and easier way for you and your physician to see the airway affected by snoring and obstructive sleep apnea.
