So get three to five personal consultations from different neurosurgeons in our own native language, this is just for your information so that you understand what the different options and opinions are. These consultations are just for your information, these will not likely be the neurosurgeon that will operate. Don't waste time, this can be done in a week to 10 days.
Also don't confuse personal sympathy with professional capacity. You want somebody who has operated a similar operation a few thousand times already. You want a genius in this medical field and not somebody to drink wine with.
I can recommend: https://www.klinikum.uni-heidelberg.de/einrichtungen/neuroch... the other option in Germany is: https://neurochirurgie.charite.de/
I can just comment on possible locations in Germany, I don't know about others around the world, but certainly there are others.
Good luck, god bless the kid

Technical expertise only needs to be good enough to treat the condition if it is treatable and empatheticly palliative if it is not.
