[Harry Potter] Since Sirius is infamous and can't go outside, could he get plastic surgery done on his face? As in, standard muggle surgery. Do wizards have any way of detecting that?

There are hints that a wizard's magic gives them some degree of unconcious protection eg harrys hair grows back in a day and Neville bounced when dropped out a window. So muggle plastic surgery would likley fade and revert. And there must be ways to find identities easily as the maurauders map does it and it was made by a bunch of kids.
