A thread/suture/stitch came out of my nose 1 year post op - what can I do? (photo)

I thought I had a clogged blackhead because it was so deep and dark, but it was located at the tip of my nose. It was hard to extract since I had tiplasty where they use ear cartilage to build my tip. It stayed for the whole month and it bugged me at lot because it was a the center of my nose which was very noticeable. I ended up trying to extract it and found out it was actually NOT a clogged blackhead. Instead a white plastic-like thread/stitch/suture came out. I am freaking out please help
