I raised my own ribs by 6mm, and my ears were small and my nasal septum was small, so I had costal cartilage surgery (I think I also had nasal septum reconstruction!!)
It's been about 4 years, and I'm pretty satisfied with it, and there are no side effects.
My nose was originally very low, but now, even though it's not flashy, it's bothersome or complex. It's not good, but it's good
