What do you mean "permanently corrupted"? Your files aren't going to magically come back. If you're asking whether it somehow damaged your microSD card, no, it didn't.
I recommend you get your saves, and reinstall anything that doesnt work, if it does work, then dont worry about it, if you get crashes, then redownload.
