I had revision rhinoplasty 18 months ago. My surgeon used a cadaver cartilage graft, I had a cortisone shot 6 months ago to help with scarr tissue, but everything was healing nicely. 2 months ago I sneezed and a hard piece came out, I thought I was crazy until yesterday I had a snotty nose and another large piece came out. My surgeons first reaction was asking if I do drugs, I do not! Has this happened to anyone else?? I’m terrified my nose is going to collapse
