In my opinion, I need to know the reference nose that you want. Now you still have bulbous tip and a bit of drooping tip. Injecting filler at dorsum can cause many problems such infection, edema, asymmetry, skin necrosis and can't maintain the contour of the nose in long term. And the last , if you want to remove the implant, you don't need to remove the rib.
