Dr. Eric Duncan surgically treats a wide range of neurological conditions, including:

Spinal Column & Spinal Cord Disorders

• Spinal Stenosis (Cervical, Lumbar): Narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.
• Syringomyelia (Syrinx): Formation of a fluid-filled cyst (syrinx) within the spinal cord, which can expand and damage nerve tissue.
• Herniated Disc (Cervical, Thoracic, Lumbar): A condition where the soft inner portion of an intervertebral disc protrudes through the outer ring, potentially compressing nerves.

Functional Neurosurgery & Neuropathic Pain Conditions

• Spasticity (severe, for Baclofen pump or selective dorsal rhizotomy consideration): Severe muscle stiffness and spasms, potentially managed with implantable drug delivery systems or nerve root surgery.
• Medically Refractory Epilepsy (for surgical evaluation): Epilepsy that continues despite trials of multiple anti-seizure medications, prompting consideration for surgical interventions.
• Trigeminal Neuralgia: A chronic pain condition affecting the trigeminal nerve, causing severe facial pain, potentially treated with microvascular decompression.

Peripheral Nerve Disorders (Surgical Management)

• Traumatic Nerve Injuries (requiring repair or grafting): Severe injuries to peripheral nerves that may benefit from surgical exploration, repair, or nerve grafting.
• Ulnar Nerve Entrapment (Cubital Tunnel Syndrome - surgical cases): Compression of the ulnar nerve at the elbow, potentially requiring surgical decompression or transposition.
• Peripheral Nerve Tumors (e.g., Schwannomas, Neurofibromas): Benign or malignant tumors arising from peripheral nerves that may require surgical excision.

This list is not exhaustive. For personalized advice regarding your specific neurosurgical condition, please consult with Dr. Eric Duncan.

• Stereotactic Radiosurgery (e.g., Gamma Knife, CyberKnife) Planning & Coordination: Collaborating with radiation oncologists for non-invasive, highly focused radiation treatment for brain tumors, AVMs, and other neurological conditions.
• Second Opinion Consultations for Neurosurgical Conditions: Providing expert second opinions on complex diagnoses and proposed surgical or non-surgical treatment plans.
• Brain Tumor Surgery (Craniotomy for Tumor Resection/Biopsy): Surgical removal or biopsy of benign and malignant brain tumors, including gliomas, meningiomas, metastatic tumors, and pituitary tumors, often utilizing image-guidance and intraoperative monitoring.
• Cerebral Aneurysm Clipping & Coiling (Endovascular coiling often with Interventional Neuroradiology): Surgical or endovascular treatment to secure brain aneurysms and prevent rupture or re-rupture.
• Skull Base Surgery (Anterior, Middle, Posterior Fossa): Complex surgical procedures to treat tumors and other lesions located at the base of the skull, often requiring a multidisciplinary approach.
• Interpretation of Advanced Neuroimaging (MRI, CT, Angiography, Myelography): Expert analysis of specialized imaging of the brain, spinal cord, and vasculature to guide diagnosis and surgical decision-making.
• Spinal Cord Stimulator Implantation for Chronic Pain: Placement of a device that delivers electrical impulses to the spinal cord to manage chronic back or limb pain.

Note: This list provides a general overview. Neurosurgical treatment plans are highly individualized. Discuss with Dr. Duncan for care relevant to your specific condition.

Are consultations and neurosurgical procedures with Dr. Duncan, a Neurosurgeon, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Neurosurgeon like Dr. Duncan, as well as most diagnostic imaging reviews and provincially insured neurosurgical procedures (e.g., for tumors, spine conditions, aneurysms), are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor or another specialist is in place. Some advanced technologies, specific implantable devices, or purely elective/cosmetic procedures may have different coverage. It's crucial to discuss coverage specifics with Dr. Duncan's office, the hospital's financial services, or Ontario Health Insurance Plan (OHIP) prior to any major procedure.

Do I need a referral to see Dr. Duncan, a Neurosurgeon?

Yes, a referral from your family physician, an emergency room physician, or another specialist (like a neurologist or oncologist) is almost always required to see a Neurosurgeon such as Dr. Duncan. Neurosurgical conditions are typically complex and require initial assessment and investigation before a neurosurgical consultation is appropriate. The referral ensures coordinated care and that you are directed to the right specialist.

What are the general risks associated with neurosurgery?

All surgical procedures carry some risks. For neurosurgery, these can include infection, bleeding, blood clots, adverse reactions to anesthesia, and neurological deficits (such as weakness, numbness, or problems with speech or vision), depending on the area being operated on. There's also the risk that the surgery may not fully alleviate the symptoms or that the underlying condition may recur. Dr. Duncan will discuss the specific risks and potential benefits of your proposed surgery in detail, allowing you to make an informed decision.

What is recovery like after neurosurgery?

Recovery from neurosurgery varies greatly depending on the type and complexity of the surgery, the underlying condition being treated, and the individual patient's overall health. It can range from a few weeks for some minimally invasive spine procedures to several months or longer for major brain or complex spine surgeries. Recovery often involves a hospital stay, followed by a period of rest and rehabilitation, which may include physical, occupational, or speech therapy. Dr. Duncan and the care team will provide detailed post-operative instructions and support throughout the recovery process.
