Clinical Associate Professor Dieter Gebauer

Clinical Associate Professor Dieter Gebauer is a dual qualified consultant oral and maxillofacial surgeon.

Born and raised in Perth, Dieter studied at the University of Western Australia completing a Bachelor of Dental Science (5 years), a Bachelor of Medicine and a Bachelor of Surgery (4 years).  Dieter has also completed the Fellowship examinations (OMS) through the Royal Australasian College of Dental Surgeons.

Dieter has recently completed his Masters of Clinical Research and practices a full spectrum of oral and maxillofacial surgical procedures, such as dentoalveolar surgery, dental implant surgery, orthognathic surgery and pathology.

Dieter’s sub-specialty interest is in facial trauma, reconstruction of the face following injury and placement of dental implants to rehabilitate lost dentition.

Dieter’s keen interest in facial trauma took him to the Illinois medical district in Chicago (the largest medical district in the world, hosting Cook County Hospital, The University of Illinois Chicago Hospital, The Veteran’s Affairs Hospital and The Rush Presbyterian Hospital) during his stay he took part in general practice residency and was later invited to return to his second year as a chief resident of the program.

Again, seeking to develop and refine his skills in the treatment of facial trauma, Dieter took a six month exchange position at Johannesburg General Hospital in 2006 which provided him with experience in a range of facial trauma, particularly gunshot ballistics trauma.

Dieter currently holds a post at Royal Perth Hospital as Head of Department and consultant facial trauma surgeon providing an on-call service and weekly supervision to the registrars at this facility.  Dieter also operates at The Park Private Hospital (formerly known as Mount Lawley Private Hospital) and is a member of their Medical Advisory Committee.

Dieter’s enrolment in the Master of Clinical Research degree at the University of Western Australia enabled him to continue his research into facial trauma, the link between skeletal facial structure and airway performance as well as the prevention of facial trauma in elite athletes.

Dieter has a passion for swimming and water polo and his achievements in this area include winning a bronze medal in the 1997 Water Polo World Championships and swimming competitively in open water events as a previous Australian youth open water swimming champion.  He has been a previous winner of the Rottnest channel swim as a solo and duo entrant and he currently plays recreational water polo with the Claremont Dolphins Water Polo Team and enjoys playing hockey with the Old Aquinian’s Hockey Club as an old boy of Aquinas College.

He is often seen stitching his crusty water polo/hockey mates up after weekend ‘warrior’ experiences.

Dieter is married to Fiona and together they have two sons,Torsten and Marius plus a French bulldog ‘Genghis’ whose interests include sleeping, snoring, eating and hockey.
