Justin X. O’Brien

Justin O’Brien is an ENT (Ears, Nose & Throat) and Head & Neck surgeon. He completed his medical degree at Flinders University in South Australia in 2008. Prior to this he was a practising physiotherapist, having graduated from The University of Melbourne in 1996, and worked in Italy and the USA before opening a private practice in Armadale, Victoria.


After medical school, Justin commenced his internship at Monash Health, while concurrently undertaking the Post-Graduate Diploma of Surgical Anatomy convened by The University of Melbourne and the Royal Australasian College of Surgeons. He was awarded the Sir Albert Coates Memorial Prize for dux. The next year he accepted the invitation to join the faculty and commence training of junior doctors on their own quest to fine-tune their anatomy prior to the surgical examinations.


Following Justin’s extended studies of surgical anatomy, he accepted an offer to proceed to a PhD in surgical anatomy of the face at the G.I. Taylor Plastic Surgery Research Centre at The University of Melbourne. He is published in multiple peer-reviewed journals on the topic. He was also a founding member of the Melbourne Advanced Facial Anatomy Course (MAFAC) and was a lecturer and dissection tutor at the course until ENT training commenced.


In 2019 Justin gained fellowship to the Royal Australasian College of Surgeons following advanced training in Otolaryngology, head and neck surgery (OHNS) which historically has been known as ENT surgery.


Justin has appointments at Cabrini Brighton, Linacre, Holmesglen, and the Royal Victorian Eye and Ear Hospital. He maintains a strong link with the St Vincent’s Head and Neck Cancer team, where he completed his final year of training.


Justin and his partner Marion have three wonderful children and have been married for 24 years.
