May I ask how long it has been since your surgery? The midline corset works in the neck plane (under the chin) and tightens horizontally and centrally. It doesn’t directly restrict vertical lift of the lower face or chin bone. Vertical changes in the lower face are more determined by the vectors of the facelift, not the neck muscle tightening. So it depends on the direction and technique that the surgeon performed to you. However, once the neck tissues are tightened and fixed centrally, it can limit how much skin and soft tissue can be lifted upward later. Technically, in my experience doing the neck lift first and then the upper/mid face can limit aggressive upward pull at the jawline margin. But the main effect is usually mild.
First of all ,I think you have to address the problem that you want to correct. and then we can discuss about the choice and method to do. 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.
