The most common neurosurgical procedures are those that treat the nervous system. These procedures include spinal stenosis, Craniotomy, and spinal cord decompression. Learn more about them in this article. After reading this article, we also look at some of the latest techniques, including Intraoperative brain mapping. What will better equip you to choose the correct procedure for your specific case?

Chiari decompression

Although it is not a cure for Chiari malformation, the procedure may help relieve some symptoms. Chiari decompression surgery can also be effective in the treatment of syringomyelia. While it cannot reverse spinal cord damage, it can alleviate headaches, neck pain, difficulty sleeping, and memory issues. It can also improve muscle weakness and numbness.

Surgical techniques for Chiari decompression can cause problems in patients with CSF buildup. Some patients experience temporary hydrocephalus as a result of post-surgical inflammation. This is generally treated without surgery, but more persistent cases may require a CSF diversion or shunt. Before undergoing surgery, patients should discuss expectations with their surgeon. The goal is to minimize pain, bleeding, and recovery time.

This surgery may require many diagnostic tests. For example, a sleep study can identify irregular breathing patterns, as well as spinal MRI and thin cut MRI. In addition, the presence of adhesions and scoliosis may require a three-foot x-ray. In children, Chiari malformation may be associated with other skeleton abnormalities, such as scoliosis. A high-resolution CT scan is also a helpful tool.


A craniotomy is a neurosurgery procedure involving cutting a skull hole to access the brain. The process is performed for several conditions, including brain tumors, aneurysms, arteriovenous malformation, and abscesses. It is also used to replace missing bone in the skull, perform diagnostic tests, or implant medical devices.

Before the operation, the patient is given general anesthesia, which ensures a pain-free experience. The surgeon will then make an incision in the scalp and reflect skin and muscle to expose the skull. A small flap of bone will then be cut and removed from the head. The bone flap will then be replaced at the end of the operation. Patients should expect a few days in the hospital.

Before the surgery, a patient will undergo a brain scan using MRI, CT, or ultrasound. Who will load this information into a computer in the operating room? This computer will give the surgeon an accurate three-dimensional image of the head and brain. This image is used to guide the surgery. A doctor may also use an ultrasound or MRI before the procedure to ensure the tumor is in the correct place.

Lumbar spinal stenosis

Lumbar spinal stenosis is a common problem that results in a stooped posture and pain when walking. It can also cause weakness in the foot and legs and difficulty with bowel and bladder control. Although the condition is typically progressive, there are several treatment options available. If you experience any of these symptoms, it may be time for you to visit a neurosurgeon to find the most appropriate treatment.

Nonoperative treatments include physical therapy, steroid injections, and medications. However, if these measures are ineffective, you may need spinal stenosis surgery to relieve pressure on the nerves. The most common procedure for spinal stenosis is a laminectomy, which involves removing the back part of the vertebra in question. Other, less invasive surgical techniques are available, which may include using a mini-incision to remove bone and reduce the risk of complications.

Intraoperative brain mapping

Intraoperative brain mapping before a neurosurgical procedure is essential for minimizing the risk of neurological deficit. This is because imaging tools can help the neurosurgeon identify the precise location of the abnormality and reduce damage to the normal brain tissue. In addition to, Neurosurgery providing the neurosurgeon with an image of the brain, the procedure can also help guide the surgeon when performing other surgeries. However, it is unnecessary to repeat the entire brain using this technique.

The surgical team will use electrical brain stimulation to stimulate specific brain parts to measure their function. These areas are critical for language and cognitive functions. Therefore, they should be encouraged only after the patient names a particular picture. Otherwise, direct electrical stimulation could cause a non-convulsive seizure. The goal is to reduce brain damage and maximize the patient’s quality of life.
