Alternative Treatments For Chiari Malformation
Open up space: Surgery is done to make more space around the cerebellar tonsils which have descended below a bony landmark called the foramen magnum. Bone is removed in the suboccipital area and extended down over the cervical bones as needed to take any bone over the tonsils off. The dura or covering over the tonsils can be opened and a patch sewn over the area to increase the space. ...Read more
Sometimes surgery: Chiari malformation type I neurological disorder where cerebellum (or more specifically the cerebellar tonsils), descends out of the skull into the spinal area, resulting in compression of parts of brain and spinal cord, and disruptsl flow of cerebrospinal fluid sxs include. Dizziness, muscle weakness, numbness, vision problems, headaches, problems of balance/ coordination. If severe maybe surgery. ...Read more
Do you have one?: You saw the malformation on an MRI, right? Who's the patient, you or the MRI? Are either you or the MRI having symptoms? If brain surgery (not a minor matter) were needed, who would have it, you or the MRI? You're making a common layperson's mistake: You're mistaking a test result for the thing itself. A Chiari malformation that causes no symptoms is much better left alone. ...Read more
I saw a doctor who diagnosed chiari malformation. Now he wants to do treatment. I suspect he is churning. What is significance of the condition?
Churning?: Treatment of chiari malformations is surgical. These are usually surgical if the patient has specific headaches, difficulty swallowing, weakness, or hydrocephalus along with other symptoms. I'm not sure quite what you mean by churning but if you're uncomfortable with your neurosurgeon, please seek another opinion. Remember that we are here to help you and you should feel that from your surgeon. ...Read more
Brain abnormality.: A type 2 chiari malformation is a brain abnormality a baby is born with, where the lower part of the brain bulges down through the hole in the base of the skull. Babies with this malformation may show symptoms like poor feeding, difficulty breathing, and weakness. It is almost always associated with spina bifida as well. ...Read more
A big question:
There are 3 main categories
i. Cerebellum is displaced about 5 mm below the level of the foramen magnum
ii. There is more than 5 mm diplacement below the level of the foramen magnum. This is usually associated with spina bifida- a defect in the spinal coverings leading to a myelomeningocoele
iii. There is cerebellum and brainstem protruding out an opening in the skull. ...Read more
Head/ Cervical MRI: Chiari malformation is best diagnosed with a head MRI without contrast to assess for the abnormal tonsil position and determine whether hydrocephalus, or water on the brain, is present also. A cervical MRI without contrast can assess for a problem called a syrinx, or a fluid cavity in the center of the spinal cord. A lumbar MRI without contrast can also exclude a tethered cord causing numb legs. ...Read more
Brain malformation: Briana, a chiari malformation is a downward congenital (from birth) displacement of the lowermost part of the a part of the brain (the cerebellum) through the opening in the base of the skull. Several types with no symptoms to multiple symptoms such as neck pain, headaches, dizziness, loss of balance, numbness of limbs. May be associated with other structural changes in the spinal cord or brain. ...Read more
Arnold-Chiari: There are acquired Chiari malformations but these are mostly due to a device placed in the lower back. Most cases are congenital meaning they are due to a malformation at the base of the skull that has been present since birth. ...Read more
Chiary II.: Chiari ii malformation (cm-ii), also known as arnold-chiari malformation, is a fetal condition characterized by downward displacement of the cerebellar vermis and tonsils, a brainstem malformation with beaked midbrain, and a spinal myelomeningocele (open spina bifida). Symptoms: lower extremity paresis, hydrocephalus, bowel/bladder control impairement, inability to indipendently ambulate. ...Read more
Arnold Chiari: There are several types of chiari malformation. Type one consists of an extension of the cerebellum below the foramen magnum. Most people with that do not have any symptoms. Type 2 is associated with a spinal cord malformation. Under certain circumstances the malformation may move further through the foramen magnum and prevent the flow of spinal fluid and increae pressure on the brain. ...Read more
Neuro dr 4 options:
Some CMs are asymptomatic and do not interfere with a person’s activities of daily living. In other cases, medications may ease symptoms, such as pain.
Surgery is the only treatment available to correct functional disturbances or halt the progression of damage to the central nervous system. Most individuals who have surgery see a reduction in their symptoms and/or prolonged periods of relief. ...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
Not know for sure: Information on genetics being investigated. Duke University Medical Center is investigating the hereditary basis of Chiari type I malformations with or without syringomyelia The research is aimed at learning if caused by inheritance factors. ...Read more
Maybe: We cannot thoroughly advise you of the risks, as there are a variety of Chiari malformations, and some are indeed risky and symptomatic. An irregular heartbeat might be a red flag of a congenital cardiac issue. Have your primary doctor assess all of this and clear you for safety prior to your sky diving. ...Read more
Surgery alternatives: If your symptoms are from the chiari, surgery is the best option. To know for sure that it's the chiari causing your symptoms is the hardest part. Sometimes the only way to find out is to proceed with surgery. Neurosurgeons who treat a lot of chiari will develop a good sixth sense for who may get better and who may not (many people have MRI findings of chiari but won't get better with surgery). ...Read more
What are causes of small fiber nueropathy? Can it progress fast? Can chiari malformation cause it?
Comments: Causes of small fiber neuropathy include diabetes, HIV, lupus, sarcoidosis, B-12 deficiency, Sjogren's, a variety of autoimmune conditions, and perhaps a few hereditary conditions, unreported in literature so far. There may well be a link with connective tissue disorders, such as Ehlers-Dalos, and some are associated with Chiari. All can be treated, but you need experienced doc. ...Read more
I was diagnosed with mild chiari malformation between 4-5mm. Can this be causing the headaches in the back of my head?
I have arnold chiari malformation type 1. I recently had corrective surgery. What are the possible side effects from that?
My best friend has chiari malformation, what type treatment would be suggested to help relieve some of the symptoms without surgery.
Yes and no: This is a disorder of spinal fluid circulation so Diamox (acetazolamide) is a medication that reduces cerebrospinal fluid output. If you have symptoms and this is more than just an incidental imaging finding, it is a long shot that this medicine will cure you. Removal of a portion of the back of the skill called suboccipital craniectomy, is a safe and effective procedure. ...Read more
I was just recently diagnosed with a mild chiari malformation by my doctor. How quickly can a mild chiari malformation progress further or does it?
It won't: Chiai malformation is seen in 10 percent of patients. And in fact if you have only the mild type you might ask how many mm does your tonsils project below the foramen magnum. Some readers only call it a real aci if it projects 10 mm below. Some readers call it at 5mm. So you should ask your doctor. ...Read more
