Cerebrovascular Disorders (Requiring Surgical Intervention)

• Subarachnoid Hemorrhage (SAH): Bleeding into the space between the brain and the surrounding membrane, often caused by a ruptured aneurysm.
• Cavernous Malformations (Cavernomas): Clusters of abnormal, dilated blood vessels that can occur in the brain or spinal cord and may cause bleeding or seizures.
• Cerebral Aneurysms (Unruptured & Ruptured): A bulge or ballooning in a blood vessel in the brain, which can leak or rupture, causing a hemorrhagic stroke.

Functional Neurosurgery & Neuropathic Pain Conditions

• Trigeminal Neuralgia: A chronic pain condition affecting the trigeminal nerve, causing severe facial pain, potentially treated with microvascular decompression.
• Movement Disorders (Parkinson's, Essential Tremor, Dystonia - for DBS evaluation): Evaluation for Deep Brain Stimulation (DBS) surgery for patients with movement disorders not adequately controlled by medication.
• 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.

Spinal Column & Spinal Cord Disorders

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

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

• Surgical Treatment for Trigeminal Neuralgia & Other Facial Pain Syndromes (e.g., Microvascular Decompression): Procedures to alleviate severe facial pain caused by nerve compression or dysfunction.
• Surgery for Traumatic Brain Injury (TBI): Emergency and elective procedures for TBI, including craniotomy for hematoma evacuation, management of skull fractures, and intracranial pressure monitoring.
• Comprehensive Neurosurgical Consultation & Evaluation: In-depth assessment of conditions affecting the brain, spine, and peripheral nerves, including review of medical history, neurological examination, imaging review, and surgical planning.
• 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.
• Second Opinion Consultations for Neurosurgical Conditions: Providing expert second opinions on complex diagnoses and proposed surgical or non-surgical treatment plans.
• Management of Brachial Plexus & Lumbosacral Plexus Injuries (Surgical Repair/Grafting in select cases): Complex surgical interventions for injuries to major nerve networks.
• Hydrocephalus Management (VP Shunt, ETV - Endoscopic Third Ventriculostomy): Surgical treatment for abnormal accumulation of cerebrospinal fluid in the brain, including shunt placement/revision and endoscopic procedures.
