Can I show a doctor a picture of a nose that I like ? And will they do the exact same one?

While it is possible to cosmetically improve the appearance
of your nose with an artistically performed rhinoplasty, if you fully expect to
get a nose exactly like someone else, you will be disappointed in your final
result. If any one promises that you can achieve that exact result, I would be
wary.
Keep in mind that following the advice from a
surgeon on this or any other website who proposes to tell you what to do based
on a limited two dimensional photo without examining you, physically feeling
the tissue, assessing your desired outcome, taking a full medical history, and
discussing the pros and cons of each operative procedure would not be in your
best interest. I would suggest you find a plastic surgeon certified by the
American Board of Plastic Surgery and ideally a member of the American Society
for Aesthetic Plastic Surgery (ASAPS) or facial plastic surgeon (ENT) that you
trust and are comfortable with. You should discuss your concerns with that
surgeon in person.

Hello,Of course not. That is fantasy.  Rhinoplasty is about improving the nose you have.  Although great changes can be made to any nose, it would generally be wrong to assume that one can get any nose they want. Go on a few consults and see what is possible using the latest photographic morphing software.Best of luck!
