Does Chiari malformation1 go away on its own?
Treatment of Chiari malformations and syringomyelia is very dependent on the exact type of malformation, as well as progression in anatomy changes or symptoms. Chiari I malformations that are asymptomatic should be left alone (this involves the majority of Chiari malformations). There is no indication for "prophylactic" surgery on these.
What is the difference between an AVM and Chiari malformation?
Differences Between Treatment. Arnold Chiari malformation Type 1 may not require any treatment. Type 2 almost always requires surgery soon after birth to correct other accompanying issues, such as closing the myelomeningocele and/or draining extra cerebrospinal fluid within the skull using a shunt.

The severity of Chiari malformation type II can vary greatly. The disorder can potentially cause severe, life-threatening complications during infancy or childhood. In Chiari malformation type II, cerebellar tissue protrudes all the way into the spinal canal.
Can Chiari malformation be cured?
There is no cure for Chiari malformation, but treatment helps to relieve symptoms and restore quality of life. Chiari type I treatment is based on a number of factors, including symptom severity and whether or not a syrinx exists.
What is the best treatment for Chiari malformation?

This will prevent further damage from occurring and could also provide relief from your symptoms. There are different ways to accomplish this goal, which can be used alone or in combination.
Minimally Invasive Treatment Options
Minimally invasive Chiari decompression, uses microscopic visualization equipment and special instruments to accomplish the same goal as traditional Chiari decompression. However, this procedure does not require a patch, uses a smaller surgical incision with less tissue disruption, and typically has a shorter recovery time.
Recovery from Chiari Malformation Treatment
Your recovery following your Chiari malformation treatment is going to be a very individual experience, with much of it depending on your individual condition and which procedure you undergo.
Choosing an Option
Because there are many different Chiari malformation treatments available, your neurosurgeon will review the options and recommend treatment plans specific to your case. Your doctor will take many factors into consideration related to your overall health, which could have an impact on the potential success and risks of certain procedures.
Putting it Together

The surgeon then removes a part of the arched, bony roof of the spinal canal, called C1, to make more room and relieve pressure on the spinal cord. Sometimes the surgeon will then round out the cerebellar tonsils to further improve CSF flow.
Can CM1 cause whiplash?
Even children with mild or asymptomatic cases of CM1 are vulnerable to the compression of brain tissue between the spinal column and the skull, and so they should avoid chiropractic therapy, roller coasters, trampolines and other activities that could result in whiplash.
