Is It Possible to Permanently Flare Nostrils?

Hi

Yes.  The nostrils can be flared out with grafts or sutures or tip de-projection but this is not something that is commonly done unless its a revision rhinoplasty where a previous plastic surgeon made the nose too narrow.  

As Dr Naderi suggested, the nostrils can be flared if tip projection is decreased. However, I would not recommend the placement of grafts because scarring may be difficult to camouflage. It would be helpful if you sent pictures.
