How Many Revisions Can One Safely Get for a Nose Job?

The number of revision rhinoplasty a patient can get is limited by the soft tissue envelope.  With subsequent procedures, some patients can get thinning of the skin and may have blanching and/or cyanosis (nose turning blue) either with exercise or cold weather.  In these cases, the nose is probably not a candidate for another procedure.  

The number or revision rhinoplasty surgeries a patient has had typically corresponds to the difficulty.  However, this is not a hard and fast rule.  There are patients with multiple rhinoplasty procedures who only need an endonasal tweak to the nose.  There are also primary rhinoplasty patients who may need costal cartilage or extensive reconstruction of the septum which may be much more complex than a revision rhinoplasty.  

Although revision surgeries gets progressively more difficult with multiple surgeries (scarring, loss of potential grafting material) , there is no absolute limit to how many rhinoplasties one can have

There is no fixed number of rhinoplasty procedures you can undergo.

The surgery becomes more complex as the tissue planes are disrupted with each surgery. This doesn't preclude additional surgery, but a risk benefit decision has to be made to assess whether further surgery is worth it. This can only be done with an in-person exam. I would recommend consulting with a few experienced rhinoplasty surgeons who you feel have good before and after results.
