Academic background


John went to Jesus College, Cambridge with an open scholarship. John’s ENT training was undertaken in Manchester and Liverpool. He won the Janet Nash fellowship to work with one of the world’s leading ear surgeons, Professor Ugo Fisch, in Zürich. John continued to work every summer with Professor Fisch on his prestigious course for 16 years. When he was appointed as consultant in Gloucestershire in 1997, John had the unusual privilege for 3 years of sharing the operating theatre with James Robinson, the UK’s leading cholesteatoma and otosclerosis surgeon. The principles and teaching of these two experts has continued to influence Mr Hamilton’s approach to ear surgery.


John runs an international ear surgery course in London; he runs a training programme for fully qualified young consultants to provide high level ear surgery skills at Gloucestershire Royal Hospital; he is often an invited speaker at Universities and regional and national societies around the world; he has written chapters for national ENT reference books; he is on the editorial board of the world’s leading ear surgery journal, Otology and Neurotology; he is the training lead for ENT registrars in Gloucestershire.


John has been performing research on the eustachian tube and middle ear for many years. He still works with the University of Cambridge and St George’s Hospital on these topics. He is best known for his research into the benefits of laser surgery for clearing cholesteatoma and preserving the hearing bones. This work is responsible for the widespread adoption of laser techniques in cholesteatoma surgery.

He has meticulous records of his surgical outcomes and theses have allowed him to constantly improve his treatment for patients throughout his career. He has identified a previously unknown phenomenon of improvement of middle ear ventilation in the second decade, which has saved many children with retracted ear drums from unnecessary surgery. He has been the first to quantify outcomes such as the spontaneous healing of ear drum perforations and long term deterioration of hearing results after surgery. His research has been commended by other leading ear specialists in journal editorials and for consideration for prizes at International meetings.
