Probably just normal healing or blow out heals and it looks strange from the video stills.

I've seen a lot of healed up gauged earlobes. Sometimes they heal back nearly perfect with a tiny little "butthole" (sorry for the descriptor but that's exactly what it looks like) or if they did a poor job expanding the gauges overtime while wearing the jewelry you'll get overpressure or infection in areas of the lobe which will cause very visible damage which looks something like "judo ear".

Sewing or correcting the damage via surgery is not typical, or at least it wasn't common place when I was still stomping in the circle pits.
