What is Chiari Malformation?
Chiari malformation is a structural condition where brain tissue extends into the spinal canal. Specifically, the cerebellum (the lower part of the brain) protrudes through the foramen magnum, the opening at the base of the skull.
Types of Chiari Malformation
-
Type I - Most common form, usually present at birth but may not show symptoms until adolescence or adulthood
-
Type II - More severe, typically associated with spina bifida
-
Type III - Rare and serious form where brain tissue protrudes into the spinal cord
-
Type IV - Very rare form involving an underdeveloped cerebellum
Common Symptoms
- Headaches, particularly after coughing or straining
- Neck pain
- Balance problems
- Dizziness
- Vision problems
- Difficulty swallowing
- Sleep apnea
- Numbness or tingling in extremities
Diagnosis
Diagnosis typically involves:
-

- Regular monitoring
Surgical Treatment
-
Decompression surgery (most common)
-
Spinal laminectomy
-
Duraplasty
