Tonsillar Herniation

The neurosurgeon is the specialist who evaluates tonsillar herniation, also known as herniation of the cerebellar tonsils or Chiari malformation, in which a lower part of the cerebellum shifts through the opening at the base of the skull into the spinal canal.

Common symptoms: It may cause headache, especially when coughing or straining, neck pain, dizziness, balance problems, tingling, or difficulty swallowing. Some people have few symptoms.

How is it identified? It is usually detected through imaging studies of the brain and the spine, ordered when compatible symptoms are present.

When to seek care? An evaluation is advisable in the face of headaches related to exertion or persistent neurological symptoms. The neurosurgeon analyzes the case and guides the most appropriate follow-up for each patient.
