Chiari Malformation Surgery Success Rate
Moderately risky: Chiari decompression surgery is considered moderate risk surgery. In other words, its not like having your appendix or hernia repaired but its also not like having a complex brain tumor or aneurysm worked on either. The major risks of this surgery are severe (sometime chronic) neck pain, bleeding, infection, and a small risk of spinal fluid leak. The more scary risks (stroke) are very rare. ...Read more
A few weeks: Most are out of the hospital in 1-2 days. You then have to take it easy (no lifting >10 lbs) for about a month. Expect a stiff neck for a few weeks at least. ...Read more
Hydrocephalus: Fluid will build up in the ventricular system of the brain with a resultant increase in pressure inside the brain/skull. ...Read more
Yes: Many people go through life completely unaware they have chiari malformation until they get their head and neck imaged for an unrelated injury. Good to know, but doesn't necessarily require surgery. If you need a spinal tap, then things get a bit murky so put it on your med history anyway. ...Read more
Chiari malformation: It depends on what type of surgery you are going to have (what your true diagnosis is... be careful!) and what job you want at the airforce. Speak with your neurosurgeon and ask details, then call the recruiting folks for the air force and ask them what they think... do not rush into it at age 48... rare to have to have Chiari surgery done at that point.... good luck! ...Read more
I have chiari malformation 1 and I have all the classic symptoms. Yet it is only 3mm. Should I get surgery?
Neurological: Symptoms guide the decision that surgery is needed, not the length of the lesion. Pressure from the cerebellum on the spinal cord or lower brainstem can cause neurological signs & symptoms. See www. Mayoclinic. Org/diseases-conditions/chiari-malformation/basics/definition/con-20031115. Seek a 2nd neurosurgical opinion if you are hesitant. ...Read more
Many things: Surgery to decompress the herniations can either focus on removing some of the bones to allow more room, or detangling the spinal cord as it leaves the brain (rarely done). This is serious surgery that can result in infections, paralysis, problems breathing, and worse. However neurosurgeons today are incredibly trained and can do amazing things! ...Read more
Possibly: Typically, asymptomatic chiari type-1 malformations are not recommended to undergo a sub-occipital decompression unless there are other associated findings. In children, if there is associated hydrocephalus, or a cervical region syringomyelia, a sub-occipital decompression may be indicated. This is to prevent future neurological decline. ...Read more
It is: Chiari described different types of developmental defects of the cerebellum. Type 2 is associated with spina bifida, type 3 and type 4 are severe defects. You are probably talking about type 2 associated with spina bifida. It can cause breathing and swallowing problems. Treatment with surgery is controversial. ...Read more
Absolutely: A chiari 1 malformation is not a dangerous condition. It is usually found incidentally during the workup for a headache. The only reason to have surgery is to relieve symptoms, and often the symptoms and the chiari are unrelated so surgery doesn't help. If you do not have symptoms, then you absolutely should not have surgery. ...Read more
Safe if experienced: As a general rule, such surgeries should be done in major medical centers or in designated childrens hospitals by neurosurgeons who specialize in pediatric neurosurgery. Under those circumstances, the surgeries are as safe as they can be made and almost always better than not repairing the malformation. ...Read more
I got results on my chiari malformation said 6mm below something and the nuero surgen doesn't want to do surgery why?
Surgery not needed: A chiari 1 malformation is not a dangerous condition, but can cause headaches, numbness, dizziness or unsteadiness. In yours, the cerebellar tonsils lie 6 mm below the foramen magnum (the hole at the base of the skull). This is fairly small and not dangerous so the only reason to have surgery is to relieve symptoms. Often the symptoms and the chiari are unrelated so surgery doesn't help. ...Read more

I have chiari malformation and we found this on an mri. Another mri for the spine and no fluid was blocked. My symptom get worse. Do I need surgery?
Neurosurgery always: Sounds scary. In truth, current minimally invasive techniques have remarkably low risk in the hands of pediatric and adult neurosurgeons. And that's who you need to ask, because the decision is not based on the size, or length, of the Chiari malformation, it's based on symptoms that interfere with a person's daily functioning. Review your MRI's with the neurosurgeon at your first consult. ...Read more

Can decompression surgery for chiari malformation 1 relieve vision problems/issues (like blurry/double vision or seeing flashes) caused by chiari?
Depends: The goal of Chiara surgery is to restore the normal pattern of CSF flow & thereby prevent further deterioration of the visual (& balance) symptoms of the ACM malformation. Whether this helps existing symptoms depends on how long those symptoms have been present, the type of surgery contemplated, it's success rate, age, & underlying factors. It's a question to ask the neurologist who knows you best ...Read more

My 9 yr old son was diagnosis with chiari malformation 1. What does "8 mm of cerebellar tonsillar ectopia with tonsillar deformity" mean? Dr wants surgery
Pretty good: The most common procedure to treat Chiari malformations is to decompress the brainstem & spinal cord by removing parts of skull/upper vertebrae. It is extremely difficult to compare outcomes as all patient situations are so different, but one study showed that 84% report significant quality of life improvement after a year. About 10% report "getting worse." Pretty good odds. Best wishes. ...Read more
