Gregory S. Weinstein

Gregory S. Weinstein, MD, FACS is Professor and Vice Chairman of Otorhinolaryngology–Head and Neck Surgery at the University of Pennsylvania Perelman School of Medicine, where he directs the Division of Head and Neck Surgery. He is internationally recognized as one of the co-inventors and most influential clinical champions of Transoral Robotic Surgery (TORS), a minimally invasive surgical approach that revolutionized organ preservation in oropharyngeal and hypopharyngeal cancers. Together with Bert O'Malley Jr., Dr. Weinstein developed and led the clinical validation studies of TORS using the da Vinci Surgical System, demonstrating that robotic-assisted transoral resection could achieve excellent oncologic outcomes with dramatically reduced morbidity compared with open surgery or even total laryngectomy. Their work culminated in FDA clearance of TORS in 2009 and has since enabled de-escalation of adjuvant radiotherapy in selected HPV-positive OPSCC patients undergoing upfront surgical resection. Dr. Weinstein has authored over 300 peer-reviewed publications and has trained hundreds of head and neck surgeons in TORS worldwide.
