Jarredddd,
I was diagnosed at 34 and had Decompression Craniectomy, with C1 Laminectomy at 35. I had disrupted CSF flow so my surgeon had to open the dura membrane and lyse the arachnoidal adhesions and then he used a dural patch to close the opening. The best advice I can give to you is to find yourself THE BEST Chiari Specialist around. You have youth on your side.....every young person I have spoken to with Chiari has healed much faster than us "OLD" folks..... Good Luck and keep us posted !!
