Overview
Pathophysiology
- The most widely accepted pathophysiological mechanism by which Chiari Type 1 Malformations occur is by a reduction or lack of development of the posterior fossa as a result of either congenital or acquired disorders.
- The cerebellar tonsils are elongated and pushed down through the opening of the base of the skull (see foramen magnum), blocking the flow of cerebrospinal fluid (CSF).
- The brainstem, cranial nerves, and the lower portion of the cerebellum may be stretched or compressed.
- Therefore, any of the functions controlled by these areas may be affected. The blockage of CSF flow may also cause a syrinx to form, eventually leading to syringomyelia. Many sufferers turn to the Chiari Institute in Long Island, NY for specialized medical attention and medication.
