Some people with Chiari malformation have no symptoms and do not require treatment.
Some symptoms of Chiari malformation such as headache and dizziness at times may be effectively treated by medication. Medication alone will not correct the root cause of the symptoms—brainstem compression. As a rule, when Chiari malformation causes symptoms that seriously impair the patient's quality of life, it is best to consider surgery.
Surgery for Chiari malformation is basically about creating more room for the brain. Surgery relieves the compression of the brainstem and spinal cord and improves the circulation of spinal fluid.
