The septal mucosa wound is healing slowly. Is it serious?

I had surgery on October 20th and it's been a little over two weeks now. I heard that 4.5mm silicone was inserted into the bridge of her nose and the nasal septum, which supports the ear cartilage at the tip of the nose. The problem is that I went to the hospital the day before yesterday and saw the doctor who performed the surgery, and he said that my ear wound and the surgery wound on my nose were healing slowly, so I never thought I would worry about this because the wounds on my body healed quickly in my life. . They tell me to apply eye ointment more often, but they say that if the nasal septum wound doesn't heal, the mucous membrane may melt. I don't know if they're scaring me or if it's really serious. There doesn't seem to be any problem with the bridge of my nose!
