It is actually quite normal. Some surgeons love imaging, while others do not. The problem with imaging, in my opinion, is that it does not have any basis in anatomic reality; in other words, I could image any nose on you which would be possible on the computer, but impossible physically. What is truly important is that you and your surgeon spend a lot of time discussing your aesthetic goals, and that your surgeon answers all of your questions. The office should be polite and caring and the facility spotless. What is mandatory is that you like the before and after images from real patients to visualize real results.
Not all surgeons do the photoshop thing. In fact I don’t. Why that surgeon doesn’t do it could be any number of reasons. He or she may not have the software or know how to do the imaging. Sone surgeons think it is an implicit guarantee of a result. Some surgrons don’t need to “sell” the procedure with what they consider a gimmick. I would say this. Going to one surgeon or avoiding another should not be based on something like whether they will photoshop your nose. It should be based on their experience as well as examples of their work you have seen.
