yu need to see a Neurosurgeon not a Neurologist . you are wasting your money . where do you live as I can give you names of chiari drs. they are all over the US
Basically - as I understand it - a Partially Empty Sella is a little section in your skull, near your pituitary glands,- behind your eyes, that gets filled with spinal fluid. This usually isn't a big issue, but it can effect vision, sinuses, and pituitary output. And cause headaches - but Chiari also causes headaches so that's a bit hard to nail down.
Are you having visual or sinus issues?
I would just keep a notebook and list any problems with vision, sinuses, and headaches or face pains/pressure. Tell your doctor about them when you see him next. Try not to worry. Usually this isn't a big deal.
This occurs much more commonly in females - 6 to 1 or so, I believe. I'm not sure why.
