Melbourne Neurosurgeon Specialising in Complex Brain & Skull Base Surgery
Professor Leon Lai
Neurosurgeon | Head of Cerebrovascular & Skull Base Surgery
A diagnosis involving the brain can be overwhelming. Understanding your condition, its natural history and whether treatment is truly necessary are often the most important first steps.
Professor Leon Lai is a Melbourne neurosurgeon specialising in complex brain and skull base surgery. His dedicated referral practice focuses on brain aneurysms, arteriovenous malformations (AVMs), dural arteriovenous fistulas (dAVFs), brain tumours, skull base tumours, acoustic neuromas, meningiomas, brain cavernomas and trigeminal neuralgia.
Patients are referred from across Melbourne, regional Victoria, throughout Australia and overseas for primary treatment and complex second opinions.
Expertise You Can Trust. Judgement You Can Rely On.
Choosing a neurosurgeon is an important healthcare decision. Technical expertise matters, but so does clinical judgement—knowing when surgery offers meaningful benefit, when another treatment may be preferable, and when careful observation is the better option.
Professor Lai combines extensive microsurgical experience with contemporary evidence to provide clear, balanced and individualised recommendations. Patients receive an explanation of their diagnosis, its natural history and the appropriate treatment options before making important decisions about their care.
When surgery is recommended, meticulous microsurgical technique and preservation of neurological function are central to every operation. Where appropriate, less invasive surgical approaches are used to minimise tissue disruption and unnecessary brain retraction while achieving the objectives of surgery. Careful wound closure and attention to cosmetic outcome are also integral to the overall surgical result.

Every Patient Deserves an Individualised Treatment Plan
Every brain condition is different. Successful treatment begins with an accurate diagnosis, understanding the natural history of the condition and determining whether intervention is truly necessary..
Treatment is tailored to the individual and may involve careful observation, microsurgery, endovascular therapy, stereotactic radiosurgery or multidisciplinary care. The aim is not simply to treat an abnormality on a scan, but to recommend the approach most likely to provide meaningful long-term benefit.
Research, Education and Leadership
Professor Lai combines a busy clinical practice with leadership, research and surgical education, helping advance contemporary neurosurgery while ensuring patients benefit from the latest evidence.
As Head of Cerebrovascular & Skull Base Surgery and Service Medical Director – Specialty Surgery at Monash Health, Adjunct Clinical Professor at Monash University, Associate Editor of the Journal of Clinical Neuroscience, and an Examiner for the Royal Australasian College of Surgeons, he is actively involved in shaping contemporary neurosurgical practice.
He has authored more than 120 peer-reviewed publications focused on cerebrovascular surgery, skull base surgery and brain tumours.
Selected Spinal Conditions
In addition to his dedicated cranial practice, Professor Lai provides assessment and management of selected spinal conditions, including degenerative disorders, spinal tumours and spinal vascular malformations.
Many spinal conditions can be managed without surgery. Where surgery is appropriate, treatment recommendations are tailored to each patient’s diagnosis, symptoms, imaging findings and long-term goals.
Second Opinions
When faced with an important neurosurgical decision, a second opinion can provide reassurance, clarify treatment options and help patients make informed decisions with confidence.
Professor Lai regularly provides independent second opinions for patients with complex brain and skull base conditions, including uncommon, recurrent and technically challenging disorders. Every assessment includes a comprehensive review of the diagnosis, imaging and available treatment options, with balanced recommendations guided by sound clinical judgement and the best available evidence.
For Referring Doctors
Professor Lai welcomes referrals for patients with complex brain and skull base conditions, including brain aneurysms, arteriovenous malformations, dural arteriovenous fistulas, skull base tumours, acoustic neuromas, trigeminal neuralgia and other technically challenging or recurrent disorders.
Referring doctors are welcome to contact Professor Lai directly to discuss complex cases, review imaging or facilitate timely assessment where clinically appropriate. Prompt communication, comprehensive correspondence and collaborative multidisciplinary care are central to his practice.
