Essential Neurological Surgery Procedures for Brain Conditions

Brain conditions need precise and delicate surgery to help symptoms and improve life quality. Neurosurgeons use many techniques for different brain disorders. These include tumors, vascular issues, epilepsy, and hydrocephalus.

Craniotomy

A craniotomy is a surgery where part of the skull is removed to reach the brain. It’s key for treating many brain conditions.

Indications and Technique

Craniotomy is needed for brain tumors, aneurysms, and brain injuries. The surgery starts with an incision in the scalp. Then, a part of the skull is removed to work on the brain.

Variations of Craniotomy

There are different types of craniotomy:

• Standard Craniotomy: The traditional method with a larger incision.
• Keyhole Craniotomy: A smaller incision approach.
• Awake Craniotomy: Done while the patient is awake to check brain function.

Brain Tumor Resection

Brain tumor resection aims to remove tumors from the brain. The goal is to remove as much tumor as possible while keeping the brain safe.

Surgical Approaches

The surgery method depends on the tumor’s location and size. Techniques include:

• Transsphenoidal Surgery: For tumors near the pituitary gland.
• Frontal Craniotomy: For tumors in the frontal lobe.

Intraoperative Monitoring

Intraoperative monitoring checks brain function in real-time during surgery. It helps avoid damage to important areas.

Ventriculostomy and Shunt Placement

Ventriculostomy and shunt placement manage hydrocephalus. This is when there’s too much cerebrospinal fluid in the brain.

Hydrocephalus Management

Managing hydrocephalus means moving excess cerebrospinal fluid away from the brain. This relieves pressure.

Types of Shunts

There are different shunts, including:

1. Ventriculoperitoneal (VP) shunts, which move fluid to the abdominal cavity.
2. Ventriculoatrial (VA) shunts, which move fluid to the heart.

Surgical Treatment for Epilepsy

Surgery for epilepsy is considered when medicines don’t work. It includes resective surgery and neuromodulation techniques.

Resective Surgery

Resective surgery removes the brain part where seizures start.

Neuromodulation Techniques

Neuromodulation, like vagus nerve stimulation, changes nerve activity. It aims to reduce seizure frequency.

Spine Surgery Procedures

Spine surgery is a range of procedures to ease pain and improve function in those with spinal issues. These surgeries aim to treat various problems, like herniated discs, spinal stenosis, and spinal deformities.

Discectomy

Discectomy is a surgery to remove damaged or herniated disc material that’s pressing on a nerve. It can help reduce pain, numbness, and weakness in the back and legs.

Microdiscectomy Technique

Microdiscectomy is a less invasive version of discectomy. It uses a microscope or special tools to remove the herniated disc through a small incision. This method can cause less damage and lead to quicker recovery.

Indications and Outcomes

Discectomy is usually for those with significant disc herniation who haven’t gotten better with other treatments. Many patients see a big drop in pain after this surgery.

Laminectomy

Laminectomy removes part of the vertebra to relieve pressure on the spinal cord or nerves. It’s often used for spinal stenosis.

Surgical Approach

The way laminectomy is done can vary, with some being more minimally invasive. The choice depends on the patient’s condition and the surgeon’s preference.

Decompression Benefits

Laminectomy can greatly relieve pressure on the spinal cord and nerves. This can lead to better symptoms, like less pain and better mobility.

Spinal Fusion

Spinal fusion joins two or more vertebrae together using bone grafts, rods, or other tools. It helps stabilize the spine and can reduce pain.

Instrumentation Options

Spinal fusion uses different tools, like pedicle screws, rods, and cages. The choice depends on the patient’s condition and the surgeon’s choice.

Recovery Expectations

Recovering from spinal fusion takes several months. During this time, patients should avoid heavy lifting, bending, or twisting. Physical therapy is often recommended to improve outcomes.

Vertebroplasty and Kyphoplasty

Vertebroplasty and kyphoplasty are minimally invasive treatments for vertebral compression fractures. They involve injecting bone cement into the fractured vertebra.

Fracture Management

Both vertebroplasty and kyphoplasty are effective for managing painful vertebral compression fractures. They provide quick pain relief and stabilize the vertebra.

Procedural Differences

The main difference between vertebroplasty and kyphoplasty is that kyphoplasty uses a balloon to create a cavity in the vertebra before injecting bone cement. This can help restore some of the vertebra’s height.
