Is donated costal cartilage really good as a support??

I have a really bad flat nose. When you look at my nose from the front, you can't see my nostrils or columella lol. I've been going around selling things these days, but each hospital tells me a slightly different story so I'm confused. But the director of the hospital I like the most says to use donated ribs as support and 3D silicone + septum + ear cartilage. He says that if you use donated ribs as support to make a columella, it will not sag or fall down as much as possible. But the internet also says that donated ribs are well absorbed~~ Which of these is true?
