Katherine C. Yung, MD, is an Associate Professor of Clinical Otolaryngology in the Division of Laryngology at the University of California, San Francisco’s Department of Otolaryngology – Head and Neck Surgery (OHNS).

One of Dr. Yung’s current research interests is the obstruction of the upper airway caused by laryngotracheal stenosis (LTS). Treatment of LTS continues to present a challenge and a wide array of surgical techniques have been employed. Despite multiple endoscopic and/or open reconstructive procedures, patients often experience restenosis as a result of the abnormal wound-healing process that initially instigated the airway obstruction. Dr. Yung and her colleagues are currently enrolling patients for this study. Other interests include the efficacy of ultrasound in observing vocal fold mobility, long term outcomes after unilateral vocal fold paralysis treatment, and various ongoing retrospective studies, reflecting the diverse research opportunities in the field of laryngology.
