Chiari Malformation

Chiari malformation is a structural defect in the brain where the cerebellum and medulla are displaced slightly downwards through the foramen magnum (the opening in the base of the skull where the brainstem forms into the spinal cord). This may be due to shortened growth of the posterior fossa, which in turn causes residual pressure to push the cerebellar tonsils towards the spinal column.



Symptoms of Chiari Malformation

The most common symptom incurred by this disorder is a severe headache, but may also include muscle weakness, nausea, fatigue, inability to balance, pain in the upper neck, and hearing problems. However, in some cases the patient may be asymptomatic.

Treatment for Chiari Malformation

If the patient is symptomatic, this disorder may be treated surgically in an effort to prevent further neurological decline. Typically, the posterior fossa is decompressed via removal of the lamina of the first (and possibly second and third) cervical vertebrae along with a piece of the occipital bone of the skull. This procedure decompresses the part of the brain at the foramen magnum and is called a suboccipital decompression. In addition, the dura mater that covers the brain and spinal cord is opened to further decompress the brain. The dural opening is then patched with synthetic or allograft material prior to closing. This is referred to as a duraplasty. The skull defect is also repaired prior to closing and is referred to as a cranioplasty.
