Hi and welcome to the Chiari forum.
I am glad you are looking for a second opinion....keeping in mind a NS gets paid if they do surgery....so, they will offer it....and many should not since they are not well informed or experienced with Chiari and ALL the related conditions.
Having the right Dr is key...and reveling ALL related conditions you have is also KEY!!
From what you wrote I know you have Chiari and Syringomyelia....any other conditions?
As for Drs in Ohio....we do have a list, the list however is NOT a referral or endorsement for those listed....our list was compiled by members here of Drs they have been to, treated by and liked....it is here for you to use to research the Drs to find the right Dr for you.
Many of us have to travel to get to the right Dr...even out of state.
