Chiari Decompression Surgery

If you are needing a Chiari decompression surgery please Schedule an appointment with one of our Neurosurgeons as soon as possible.

What is Chiari Decompression Surgery?

Chiari decompression is a specialized neurosurgical procedure designed to relieve pressure caused by Chiari malformation—a condition where brain tissue extends into the spinal canal. This surgery helps restore normal flow of cerebrospinal fluid (CSF), reduce symptoms, and protect the brain and spinal cord from further damage.

What Is Chiari Malformation?

Chiari malformation occurs when part of the cerebellum, the lower portion of the brain, pushes downward into the spinal canal. This displacement can block the flow of CSF, leading to pressure on the brain and spine. Over time, it may cause a wide range of symptoms, from headaches and neck pain to balance problems, numbness, and difficulty swallowing.

Chiari malformations are often congenital, meaning they develop during fetal growth, but they can also occur later in life due to injury, infection, or structural changes in the skull.

When Is Surgery Recommended?

Not all Chiari malformations require surgery. In mild cases with few or no symptoms, regular monitoring may be sufficient. However, when symptoms worsen or interfere with daily life, decompression surgery is often the best option.

Common reasons to consider Chiari decompression include:

  • Persistent headaches, especially at the back of the head

  • Neck pain or stiffness

  • Dizziness or balance issues

  • Tingling or numbness in the hands or feet

  • Difficulty swallowing or speaking

  • Sleep apnea or breathing irregularities

  • Progressive neurological deficits

Early intervention can prevent permanent damage to the brain and spinal cord.

What to Expect During Surgery

Chiari decompression surgery, also known as posterior fossa decompression, typically involves several steps:

  1. Scalp Incision and Bone Removal: The surgeon makes an incision at the back of the head and removes a small portion of the skull to create more space.

  2. Dura Opening and Expansion: The dura, the tough membrane covering the brain, is opened and may be expanded with a graft to reduce pressure further.

  3. Tonsil Shrinking (if needed): In some cases, a portion of the cerebellar tonsils may be reduced to improve fluid flow.

The entire procedure usually takes several hours and is performed under general anesthesia. Most patients spend a few days in the hospital after surgery.

Benefits of Chiari Decompression

Chiari decompression offers significant relief for many patients. By restoring normal CSF flow and reducing pressure, surgery can:

  • Relieve chronic pain and discomfort

  • Improve balance, coordination, and motor function

  • Reduce or eliminate numbness and weakness

  • Prevent further neurological deterioration

While results vary, most patients experience noticeable improvement within weeks to months after surgery.

Recovery and Follow-Up

Recovery time varies by individual. Most people return to light activities within a few weeks and gradually resume normal routines. Follow-up appointments, physical therapy, and imaging tests help monitor healing and long-term outcomes.

Patients are encouraged to avoid heavy lifting, high-impact sports, or strenuous activity until cleared by their neurosurgeon.
