Hi May3!
There are several people on the Forum who have had this surgery, i believe at the Skull Base Institute in CA.
Please read here for one:
http://anausa.org/forum/index.php?topic=8611.0 You can read about experiences by highlife and jerseygirl, and i am sure there are others.
I don't know about Dr. Jho but have heard the name before. You can try doing a search under Physician category.
I also want to say WELCOME to the Forum! There are lots of new folks and sometimes i miss the posts
I have been on the Forum almost a year, and my sis and i both have an AN - mine diagnosed 6 months after hers.
Since i am in W & W, i can not help you with surgery particulars - but there is information here and you can search by typing in the docs name in the search box.
Good luck with your research and many prayers and good thoughts on your AN journey.
We all are here and understand!
Sincerely,
Sue
