Black Celebrities rhinoplasty getting the better results than the general population? (photo)

You are somehow fully right; if anyone takes the time to google images of b&a cases of black or asian origin (the really most difficult top ethnic rhinoplasties, requiring massive grafting and 4-6 hours of surgical time), each of us may express the same: "how come! the after is so similar if not identical to the before look!!!".Reason's mix for this is the extreme difficulty of black and asian (specially Filipino) noses, the fatigue of such long procedures for the surgeon, the very expensive cost of a long and top-notch multigraft procedure, the required training and skills due (hard to meet in a single surgeon), the marketing issues (letting a patient know his/her procedure is going to be a pricey or even unaffordable technical nightmare is not a top seller, obviously...), etc.So surgeons normally take a shortcut and perform a complimentary procedure in a short time and 2-3 technical gestures, leading thus to disappointing and minimal enhancements.On the other hands we have, also mentioned by you, the multi-staged ethnic afroamerican or asian noses, multi-staged because every procedure or surgeon adds a new layer of maneuvers or skills to supplement or correct the previous work (when, ideally and in real good hands, all should be applied at once in a standalone procedure).Furthermore, in some cases the surgeon is bold and brave enought to try the full-set of ethnic overhaul.. and end in poor or botched results... as in many of the exampled you have very suitably posted; some of the cases shown in your question have very poor or bad results, fake tips, sunken dorsums, collapses, etc.In summary, it is not relevant you are a celebrity or not to get a complete work and a radical change for your ethnic nose, actually IMHO normal individuals get much better rhinoplasties (and cosmetic surgery in general) than VIP ones (reasons are varied, but is a fact, we all have in mind examples).The key is finding a very good surgeon of complex noses with solid experience and... understand your afroamerican, asian or arab (among other) taking 4-6 hours nose can't cost the same than a basic reduction rhinoplasty done in a snap. If you want to make it more affordable do consider travelling abroad, there are excellend afroamerican nose surgeons outside the US.A bunch of good images would be required to provide overal assessment of your case.
Feel free to request any additional information from me.

There are only a few surgeons who actually do celebrity rhinoplasty.  99% of surgeons do not, and just comment and talk about it.  Find a surgeon carefully by word of mouth.  Celebrities don't use google. They trust word of mouth referrals. 

Those of us who do AA celebrities find their goals are like the general population--some want less drastic change and some want more. Discuss your goals with an experienced rhinoplasty surgeon who does many AA noses--remembering that celebrities don't admit to having had cosmetic surgery!
