Is it safe to have an open Rhinoplasty with Raynaud's Syndrome?

A rhinoplasty can be performed safely in a patient with Raynaud’s. The chance of poor healing due to this condition is very low, alongside that of those without the condition.  
In choosing open versus closed rhinoplasty, a fully-trained plastic surgeon will first determine your goals and then outline a treatment plan which fits both your aesthetic ideal and the technique which will give you the best results in his or her hands. This is often shaped by the years of experience each surgeon has honing his or her technique.  Each procedure comes with its own pros and cons, and a fully-trained plastic surgeon will be able to outline these in detail at the time of your consultation.  

Nina,
Great questions!  Rhinoplasty should not produce any significant risk due to your underlying condition.  The nose has very robust blood supply from many areas and the columella incision will no propose an additional risks.
