Help! My doctor placed ear cartilage at my nasal root. How can this be removed?

Unhappy my rhinoplasty results, specifically the nasal root. My surgeon added harvested ear cartilage and placed it into my nasal root to add volume. This turned out badly. It looks like a big bump above my nose. I sought the help of a different surgeon, and he removed as much of the cartilage as he could. However, some pieces of the cartilage still remain as if they are glued there. Is there any way to completely remove the cartilage? I'm afraid it has been glued too tightly.
