Chiari malformation is a condition in which brain tissue extends into the spinal canal. It happens when part of the skull is misshapen or smaller than is typical. The skull presses on the brain and forces it downward. Chiari malformation is not common, but increased use of imaging tests has led to more diagnoses. Mr Irfan malik is a distinguished specialist in neurosurgery, with a focus on Arnold chiari malformations
There are four types (type 1 to 4), with type 1 being the most common and least severe, typically diagnosed in adulthood. Type 2 to 4 are rarer and more severe, often identified in infancy
Symptoms can include headaches, neck pain, balance problems, dizziness, muscle weakness, numbness and difficulty in swallowing . symptoms depending on the type and severity
It can be congenital (present at birth) due to structural issues during fetal development, or acquired later in life, often linked to trauma or other conditions
Arnold chiari malformation refer to structural defects where parts of the brain extend into the spinal canal. These malformations affect the cerebellum, which controls balance, and have four types. MRI is the gold standard for diagnosing chiari malformations. It provides detailed imaging of the brain and spinal cord, showing the extent of brain tissue protrusion into the spinal canal
Stop taking all non-steroidal anti-inflammatory medicines, blood thinners like (coumadin, aspirin, Plavix etc.) 7 days before surgery. Stop using nicotine and drinking alcohol 1 week before and 2 weeks after surgery to avoid bleeding and healing problems
The most common surgery for chiari malformation is called posterior fossa decompression. Surgery involves removing a small section of bone in the back of the skull. This relieves pressure by giving the brain more room. During surgery, the covering of the brain called the dura mater may be opened. Also a patch may be sewn in place to enlarge the covering and provide more room for the brain. This patch may be an artificial material, or it could be a tissue harvested from a different part of the body.
After surgery, you can expect headache and neck pain from the incision that may last several weeks. You will be given neck exercises to do at home. These will help the neck mobility and healing. Patients typically return to work in 4 to 6 weeks, but be sure to check with you surgeon
