Functional Neurosurgery & Neuropathic Pain Conditions

• 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.
• 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.

Peripheral Nerve Disorders (Surgical Management)

• Ulnar Nerve Entrapment (Cubital Tunnel Syndrome - surgical cases): Compression of the ulnar nerve at the elbow, potentially requiring surgical decompression or transposition.
• Traumatic Nerve Injuries (requiring repair or grafting): Severe injuries to peripheral nerves that may benefit from surgical exploration, repair, or nerve grafting.
• Carpal Tunnel Syndrome (severe cases requiring surgery): Compression of the median nerve at the wrist, where surgery (carpal tunnel release) may be indicated if conservative treatments fail.

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 Fractures & Instability (Traumatic or Pathologic): Breaks in the vertebrae or spinal instability often requiring surgical stabilization.
• Spondylolisthesis: A spinal condition where one vertebra slips forward over the vertebra below it, sometimes requiring fusion.

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

• Spinal Fusion & Instrumentation (Cervical, Thoracic, Lumbar): Surgical stabilization of the spine using bone grafts and/or metallic hardware for conditions like instability, deformity, or after trauma/tumor resection.
• Deep Brain Stimulation (DBS) Implantation & Management (for Movement Disorders, Epilepsy, Pain): Surgical placement of electrodes in specific brain areas and programming of the stimulation device for conditions like Parkinson's disease, essential tremor, dystonia, or epilepsy.
• Syrinx (Syringomyelia) Decompression Surgery: Procedures to drain or shunt fluid-filled cavities (syrinxes) within the spinal cord.
• Second Opinion Consultations for Neurosurgical Conditions: Providing expert second opinions on complex diagnoses and proposed surgical or non-surgical treatment plans.
• 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.
• Nerve Biopsy for Diagnostic Purposes: Obtaining a small sample of a peripheral nerve for pathological examination.

Epilepsy Surgery (e.g., Temporal Lobectomy, Lesionectomy, Corpus Callosotomy - in selected cases): Surgical interventions for medically refractory epilepsy, aimed at removing or disconnecting the seizure focus.

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