Hello, I had a revision rhinoplasty done 2 months ago. First surgeon bascially broke the cartilage at the tip of my nose and tried to rebuild my tip using my cartilage. It made my tip crooked and pointy. I had a revision done and the doctor removed the cartilage that was used to build up my tip and used alloderm instead to rebuild my tip. My nose does look great and it looks natural. Does alloderm resorb overtime? Will my tip collapse? Also, can alloderm be used as a columella strut?
