Korean double jaw surgery?

[GreenTea123]

I am expecting to have double jaw surgery for my underbite sometime late this summer. While I was doing some random searches on double jaw surgery, I came across this article http://www.nydailynews.com/life-style/health/s-korea-painful-beauty-fad-bone-cutting-jaw-surgery-article-1.1356287. It basically talks about double jaw surgery as something done purely for cosmetic reasons - essentially a plastic surgery. The article talks about people who have NO facial or dental problems, meaning no overbite/underbite issues, they have normal bites, but they go through this surgery to have a slimmer jaw line. The article basically talks about jaw surgery in a way that makes it sound extremely dangerous and that risks such as having permanent numbness and paralysis are almost common occurrences. Obviously, this is making me worried since this procedure sounds the same as the double jaw surgery I am about to have for my underbite.

My surgeon told me that permanent numbness on the lower lip is quite common, but I am not too worried about that. What I am more worried about is the severe type of permanent numbness and even paralysis that the article talks about. I was wondering if anyone here knows anything about the Korean double jaw surgery and whether if it is the same surgery as the type most of us here are having for our bite problems. Also, if the risks and dangers of double jaw surgery are really as prevalent as the article makes it out to be. Because the thought of having facial paralysis as a result of surgery is terrifying.

The article isn't using the correct terminologies when describing the surgery. These woman don't just get double jaw surgery, they also get their jaw sawed and reshaped into a V shaped, hence why the scarring tactics written there. Obviously, double jaw surgery is invasive and does come with serious potential risks, but they make it seem that all bad cases that come from there are from the regular jaw surgery, which is not the case.

Also, reason complication rates are high there is mainly because the competition in the field is ridiculously high which means some the clinics offering these procedures tend to use interns/students to operate on their patients, it's not even the head doctor who's doing the work. Scary stuff.
