Overview of Chiari Malformation Surgery
Chiari malformation (CM) is a condition in which the lower part of the brain, known as the cerebellum, extends down through the foramen magnum, a small opening at the base of the skull. It is a congenital defect, meaning it is present at birth and can cause a variety of symptoms including headaches, neck pain, dizziness, and balance problems. Surgery is the most common treatment for CM and involves creating more space at the back of the skull to allow the cerebellum to move into a more normal position.
Success Rate of Chiari Malformation Surgery
The success rate of Chiari malformation surgery is highly variable and depends on a number of factors including the severity of the condition, the type of surgery performed, and the expertise of the surgeon. Generally, the success rate of CM surgery is estimated to be anywhere from 70-90%, though the exact rate will vary from patient to patient. Additionally, even if the surgery is successful in relieving symptoms, it is not always possible to completely eliminate them. This means that while the success rate of CM surgery is generally quite high, there is still a risk of experiencing some residual symptoms.
