Hi and welcome to the Chiari forum.
The link of the list of drs is just that a list of names...depending on where u r and what area u r willing to travel to u select a few names and do some research..we do have info on The Chiari Institute and The Chiari Center....When u see a blue hyperlynk just click on it...plus we do have a thread right here on the forum......

Brain slump or cerebral ptosis is what happens when too much bone is chipped away to make room for the CSF to flow....
I know of several people that had this repair...
Unfortunately it leaves a few other issues a chance to overtake u...infection, a CSF leak, even IIH (intra Cranial Hypertension....)
U deff want a true chiari specialist to help u.....it is possible that u have issues as a result of the surgery and not the cerebral slump....
I hope u r able to locate a few others on here that can share their experience with brain slump, I know there r a few.....
We r happy to have u join us, but sorry for the reasons that bring u.
