Benjamin Jonker MB BS MMed(Clin Epi) FRACS

Dr Jonker is an Australian neurosurgeon with expertise in both operative neurosurgery and stereotactic radiosurgery.

His hospital appointments are at Royal Prince Alfred Hospital, Chris O'Brien Lifehouse at RPA and St Vincent’s Public and Private Hospitals in Sydney.

He completed his medical degree at the University of Sydney in 1999. By the time he graduated he was convinced that he wanted to pursue a career in neurosurgery and following an internship and residency at Royal Prince Alfred Hospital he undertook his neurosurgical training at Prince of Wales, Sydney Children’s, Royal North Shore, Canberra and Westmead hospitals. This culminated in the award of the FRACS (Neurosurgery) in January 2009.

In 2009 he travelled to Foothills Hospital in Calgary, Canada and to UCLA in Los Angeles, USA to undertake fellowships in Stereotactic and Functional Neurosurgery / Stereotactic Radiosurgery with Dr Zelma Kiss and Dr Antonio De Salles respectively. This has allowed Dr Jonker to specialise in the treatment of brain tumours and trigeminal neuralgia with both operative neurosurgery and stereotactic radiosurgery. He also has subspecialty expertise in Deep Brain Stimulation (DBS) for Parkinson’s Disease and other conditions, and MR guided Focussed Ultrasound (MRgFUS) for Essential Tremor. In addition Dr Jonker also undertakes surgery for other brain conditions such as hydrocephalus and trauma. In keeping with his subspecialty training in stereotactic and functional neurosurgery he has a particular interest in performing awake surgery for brain tumours in critical locations. He also uses intraoperative MRI at Royal Prince Alfred Hospital (Australia’s first and NSW only one) to guide safe maximal resection of tumours.

Dr Jonker holds a masters degree in epidemiology - the science of designing clinical research and applying the best available evidence to a patient’s problem. He is a Clinical Senior Lecturer at the University of Sydney where he lectures for the Sydney Medical Program. His primary research interest is in trigeminal neuralgia in collaboration with the Surgical Outcomes Research Centre of the University of Sydney.

Dr Jonker serves on the Research Committee of the Neurosurgical Society of Australasia. He also teaches and serves on the committee for the College of Surgeons CLEAR course aimed at teaching the principles of Evidence Based Medicine to surgeons.

He is a member of the Neurosurgical Society of Australasia, the Congress of Neurological Surgeons (USA) and the American Society of Stereotactic and Functional Neurosurgery. He is on the medical advisory committee of the Trigeminal Neuralgia Association of Australia.

Dr Jonker’s practice is “Central Neurosurgery” which refers to both the central Sydney location of his practice and his focus on neurosurgical conditions of the central nervous system.
