If you are intending to have a rhinoplasty, first do your homework. Check out the credentials of your surgeon. Is he or she a qualified Plastic or ENT surgeon? Are they experienced? Do they have a special interest in Rhinoplasty?
Look up online reviews, although always take them with a grain of salt as their veracity is often not checked. Ask to see photos of the surgeons work if not available online.
On presenting for the consultation make sure you have a list of the things that bother you. Is it the profile or the width or the projection of the nose that bothers you? Is the tip too bulky or does it droop? Is the nose straight? Can you breath properly? The more specific you are the more likely is your surgeon to understand your aesthetic ideal.
Your surgeon should have a good imaging system to convey their thoughts and build a rapport with you. He or she should explain to you how they are intending to deal with your issues. You should also have an idea of what your postoperative course is likely to be. For example, when can you get back to work?
At the end of the consultation you should have a clear understanding of the procedure, what risks are involved and how much it is likely to cost. If uncertain whether to proceed it often is worthwhile to seek a second opinion.
