"incisionless otoplasty" is dangerous?
 

I see that incisionless otoplasty is allegedly better for you because there are no cuts/incisions/stitches but I don't understand how they weaken the cartilage to change the shape of the ear? If they inject something in there that destroys cartilage think what that does to your brain and wherever else it flows to. It looks a lot less predictable of a method. I know that most otoplasties I have seen on dr's websites suck so far but if they cannot do those right I don't know how they are going to have enough control with this method to give you what you want.

I haven't even heard of incisionless otoplasty. What is it they are injecting and how is it done?

Even if it is safe to me it sounds like a less predictable method because you don't know how the cartilage will respond since we're all different.

For purposes of curiosity, I would like to know more about this surgery as well.
