Indent in nose post-rhinoplasty

8 months post-op I have a dent at the bridge of my nose where the bump was shaved down. It is visible to the eye. I also still have a slight bump on the side of the bridge. Surgeon has told me this occurred post op when we were trying to fix an issue with the cartilage moving out of place through massaging. They have agreed to fix it using a closed approach by shaving down the residual bump and using the bone dust to fill the dent at the bridge. Will this work?
