I just noticed now that the picture looks a bit worse than it actually is. It looks like there's a small chunk of his ear missing, but that's actually just hair. I didn't finish trimming the rest of the ear after the incident, so most of it is actually his hair. I didn't actually cut a chunk of his ear off (thank goodness!)...the scissors just glazed/skimmed the edge of his ear while taking the hair off.
Thanks everyone, for the help and well wishes
