In other hospitals, they said that it was easy to sand them down with something like sandpaper because they were all slightly there, but in one hospital, they said that I had to hit them with something like a hammer. They say that if you just trim it, the bone will come back. So they say I have to undergo general anesthesia, which is scary.. What happens if the slight hook grows back? Isn't the silicone holding it down anyway? They say it will come up even if you press it there, but I don't know what it looks like from the outside.
