I once had a second surgery from Dr. MVP
 (the first surgery was a failure in the local area).
 
It's been about 5 years since then, and it has loosened up a bit, and I was worried about the original inner twin line that appeared as I got older,
 so I looked for it to be done again this time. He re-established it as ㅅㅍㄴ,
 
but I haven't heard any new news, and there was also some bad news...
 I don't know the latest news since there were no reviews after it changed to ㅅㅍㄴ.
 I'm curious whether it's still popular these days and whether they recommend repeat surgery.
