What Is Chiari Decompression Surgery?
Who Needs Chiari Decompression Surgery?
The muscles attached to your skull and spinal bones are elevated. Using a fine high-speed drill, a small window of bone (2.5cm diameter) is removed from the base of the skull. This creates more space for the cerebellum and decompresses the brainstem.
Because the tonsillar herniation frequently extends into the spinal canal, the posterior arch of the first cervical vertebra, C1, is also removed.
This procedure is often sufficient, and no further treatment is necessary. However, some special cases may need further treatment or surgery.
Most patients are able to go home 1 – 2 days after surgery. During the first 24 to 48 hours, make sure you have someone at home who can assist you. Always follow the care instructions provided by your surgeon.
