Nobody is going to hammer you for not reporting procedures that were done on you before kindergarten. Nor are they going to take issue if you DO decide to report them on subsequent medical histories. Before it would ever get to the enforcement people it would have to be referred to them by the docs at OKC who would probably smile briefly before wondering if they had reported that stuff on their own physical histories.
A childhood history of seizures, on the other hand, they’d like to know about.
