Otolaryngology (ENT/Ears, Nose, Throat)
Dr. Belafsky's primary clinical interests are the comprehensive diagnosis and management of voice, swallowing, and airway disorders. As Director of the Voice and Swallowing Center at UC Davis, Dr. Belafsky treats a wide array of laryngeal and esophageal disorders. These disorders include but are not limited to vocal fold paralysis and paresis, vocal fold dysfunction (VCD), laryngopharyngeal reflux (LPR), chronic cough, and dysphagia caused by stroke, ALS, Zenker's diverticulum, esophageal motility disorders, Parkinson's disease, and swallowing problems suffered as a consequence of the treatment of head and neck cancer. Dr. Belafsky has pioneered minimally invasive treatments of voice and swallowing disorders. Minimally invasive in-office procedures performed by Dr. Belafsky at the Center include unsedated treatment of laryngeal polyps, leukoplakia, and papillomas, subglottic, tracheal, and esophageal strictures, and office-based vocal fold medialization.
Dr. Belafsky's primary passion is the innovative treatment of profound swallowing disorders. He has created a medical device that can manually control the upper esophageal sphincter, is working on an innovative dilator for upper esophageal sphincter stenosis, is developing a comprehensive swallow propulsion system, and is evaluating the use of muscle stem cells for dysphagia rehabilitation.
