Syringomyelia
Treatment for Chiari I malformation depends on whether you have any symptoms and how severe they are. You might not need any treatment if you don't have any symptoms.
Painkillers can help relieve any headaches and neck pain.
If your headaches are severe or you have problems caused by the pressure on your spinal cord (such as movement difficulties), surgery may be recommended.
The main operation for Chiari malformation is called decompression surgery.
Under general anaesthetic a cut is made at the back of your head and the surgeon removes a small piece of bone from the base of your skull. They may also remove a small piece of bone from the top of your spine.
This will help reduce the pressure on your brain and allow the fluid in and around your brain and spinal cord to flow normally.
Other procedures that maybe necessary include:
The aim of surgery is to stop existing symptoms getting any worse. Some people also experience an improvement in their symptoms, particularly their headaches.
However, surgery sometimes results in no improvement or symptoms getting worse. There's also a small risk of serious complications, such as paralysis or a stroke.
Talk to your surgeon about the different surgical options and what the benefits and risks of each are.
A Chiari malformation, previously called an Arnold-Chiari malformation, is where the lower part of the brain pushes down into the spinal canal.
Many people with a Chiari I malformation will not have any symptoms. Sometimes they're only found after an (MRI) scan of the brain is carried out for another reason. If you develop syringomyelia, you may also experience problems using your hands, difficulty walking, pain, and problems with bladder or bowel control.

The exact cause of Chiari I malformations is unknown. It tends to be present from birth, but is normally only found in adulthood when symptoms develop or when an MRI scan is done. Many cases are thought to be the result of part of the skull not being large enough for the brain.
