Surgical Approaches

A Chiari decompression, also called a posterior fossa decompression, suboccipital craniectomy or foramen magnum decompression, is a surgical procedure performed by a neurosurgeon to treat the symptoms of Arnold Chiari malformation, particularly for Type I malformations. Symptomatic patients with Type I Chiari Malformation are often offered this treatment option.
