After Moh's surgery for basal cell carcinoma, questions about pus, grafts. (Photo)

Hello, 
It is difficult to tell from the photo. You should have the wound evaluated by a board certified plastic surgeon. I would not recommend letting the wound heal by itself because it will contract and distort the shape of the nose. Good luck with your recovery.

Hi David,
that does not look like pus. Generally what you will see is some necrotic (dead-ish) skin debris. Without a graft, expect your nostril to get pulled up pretty significantly as the wound heals. However, in this location, a skin graft would not be the first option for reconstruction.
