Chiari Decompression
Chiari decompression, also known as Chiari decompression surgery or posterior fossa decompression, is a surgical procedure performed to address Chiari malformation. Chiari malformation is a structural defect in the base of the skull and cerebellum, where a portion of the cerebellum extends into the spinal canal. This can lead to compression of the brainstem and interfere with the normal flow of cerebrospinal fluid.
During Chiari decompression, the surgeon typically removes a small portion of the bone at the back of the skull (suboccipital bone) to create more space for the cerebellum. In some cases, a small portion of the upper cervical spine may also be removed to further relieve compression. This decompression allows the cerebellum to return to its normal position and reduces pressure on the brainstem.
The procedure may also involve removing a small piece of the dura mater, the tough outer layer of the brain’s protective covering, to allow for more space and improve cerebrospinal fluid flow. A chiari decompression is often recommended when Chiari malformation causes symptoms such as headaches, neck pain, difficulty swallowing, and other neurological issues. The goal of the surgery is to alleviate symptoms, improve cerebrospinal fluid dynamics, and prevent further progression of the condition.

Conditions Related To Chiari Decompression
Kyphosis
Kyphosis is a medical term used to describe an excessive outward curvature of the spine, leading to a forward rounding or hump-like appearance in the upper back or thoracic region.
Radiculopathy
Cervical radiculopathy is a condition characterized by compression or irritation of the nerve roots in the cervical spine (neck region). This compression can result in pain, numbness, tingling, or weakness that radiates into the arms.
Myelopathy
Cervical myelopathy is a condition characterized by dysfunction of the spinal cord in the neck region, specifically in the cervical spine. It is often caused by compression or narrowing of the spinal canal, leading to a range of neurological symptoms.
Cervical Stenosis
Cervical stenosis refers to the narrowing of the spinal canal in the neck region, known as the cervical spine. This narrowing can put pressure on the spinal cord and nerve roots, leading to a variety of symptoms.
Headaches
Headaches are a common and often disruptive condition that can vary in intensity, duration, and cause. They can stem from a variety of factors, and understanding the different types of headaches can be crucial for effective management.
Neck Pain/Stiffness
Neck pain and stiffness are common symptoms that many individuals experience at some point in their lives. These symptoms can arise from various causes, ranging from muscle strain to underlying medical conditions.
Herniated Disc
Cervical herniated disc is a condition that occurs when the outer layer of a disc in the neck region tears, causing the inner material to protrude and potentially irritate nearby nerves.
