When do infections and necrosis usually occur after rhinoplasty?

Infections are indeed rare with rhinoplasty as is skin necrosis. Since a splint will be on your nose for a week skin necrosis may only be apparent after the splint is removed. But in thirty years I’ve never seen, so it is indeed rare.

When a foreign body implant is not placed in the nose, and if there is no preexisting sinus infection, infection may not occur after rhinoplasty if no nasal packing is used. We have not seen infection nor necrosis in any of our patients after 21 years of performing rhinoplasty. Necrosis should not happen with such a vascular organ. Hope this helps. Dr Joseph

Surgical infections typically occur between 4 and 7 days post-op. Infections and tip necrosis, while possible, are almost unheard of in rhinoplasty, especially in primary (vs. revision) surgery. In nearly 20 years of practice I've never had a rhinoplasty infection or tip necrosis.All the best,
