Hello @rg46 and welcome to Connect. I can certainly understand your concern for your daughter's seizures and also for the surgery. It does sound like a difficult surgery to consider, especially for a youngster.

We have another member on Connect, @mmas, whose daughter had this surgery. Here is a link to her post explaining her daughter's experience,

Has your daughter had seizures since birth?
