Is Asian rhinoplasty more or less expensive than regular rhinoplasty?

Asian rhinoplasty doesn't necessarily cost more than a Caucasian rhinoplasty. The cost is typically related to the complexity of the procedure and whether it is a revision case. 

For your understanding, a basic reduction rhinoplasty of any race is about 1 hour surgical time, or less in master's hands. Obviously they are the cheapest.
A medium complexity rhinoplasty is 2-3 hours, in case it requires some grafting, of any race. Price a bit increased.
A high complexity one is about 3-4 hours, requiring multiple grafting, like arab, latino, jewish ones for example. Can be considered expensive.
And very high complexity ethnic noses, which are asian and black (afroamerican and afrocaribbean), take 5-7 hours and are a real technical challenge accessible to few talented surgeons. They are quite expensive.
Mention apart for the out-of-rank filipino rhinoplasties, the hell for rhinoplasty surgeons; I tell you by own experience as multi-race nose surgeon, I've tried them all.
Asian rhinoplasties may cost twice than a basic reduction nose job. Alternative? doing a quick hackjob.
May anyone tell you an asian rhinoplasty costs the same than a regular case... is like someone telling you a heart transplantation should not differ from pacemaker insertion... run away the fastest you can, you might be talking with Dr. Nick Riviera!
If you research asian rhinoplasty cases online you'll find somethin awesome: 99% of the before and after cases look just slightly different if not literally the same; this may answer your question.
Additionally, if you explore my Q&A list or in general in the whole RS you'll find a majority of asian rhinoplasty patients complaining of poor and non sufficient change, or maybe got shortcuts like prosthesis and other rubbish inside the nose.Final note: inversely... if someone somewhere says a basic reduction rhinoplasty will cost the same than an afroamerican or asian... could be due to the poor quality of the ethnic cases... or, why not... they are adding and abusive overprice to the basic rhinoplasty cases. You must pay for what you get, and you have to get what you deserve / need technically, just it, fair play.
