There are rumours that say that Portia de Rossi has had some plastic surgical procedures. I have been looking for evidence to prove that myth and let me tell you that when it comes to her boobs, Portia has always been flat and there are not pictures on the web (at least that I could see that prove otherwise).
New and old pictures of Ellen Degeneres wife show the star with a very flat chest.
About facial cosmetic surgeries the most recent pictures show the face of a 40 years old woman that shows now some signs of ageing.
Finally, about her nose I don’t think Portia has reshaped her nose.
