An academic poster from the 2017 British Association of Oral and Maxillofacial Surgeons Annual Conference. We outline that patient outcomes of orthognathic surgery are complex and include physical changes, mental and physical health improvements, and psychosocial adjustments1,2. To our knowledge, investigations of the personal and societal impact of orthognathic surgery using the government recognised SROI framework have not been published before. This study represents a collaboration between the University of Gloucestershire, and Gloucestershire Hospitals NHS Trust, involving patients following orthognathic surgery at Gloucester Royal Hospital (GRH).
