Surgeons test innovative combo procedure for rare brain disorder
Disease control CompletedThis study tested a new surgical procedure for people with Chiari malformation and type II skull base depression, a condition where brain tissue extends into the spinal canal. The surgery combined decompression, joint release, and fusion to relieve pressure and stabilize the spin…

Brain surgery showdown: which chiari fix works best?
Disease control CompletedThis study looked at 250 people with Chiari malformation type I and syringomyelia to compare two surgical approaches: one that opens the covering of the brain and spinal cord, and another that also removes or shrinks the tonsils at the base of the brain. The goal was to see which…
