Trachea shave 12 months ago - Skin stayed attached to the cartilage (photos)

I had a trachea shave on 03/08/2022 with an incision under the chin. A tunnel was created to access and shave the cartilage. Initially I had a huge bumb, larger than my original cartilage, however I was told that it will disolve within six months. My other concern was that my skin get pulled up and down when I swallow and creates a non-attractive, wrinkle looking skin on my neck. Attaching pictures. Please help me to understand whats going on and what is the solution to this issue?
