About the RED System
The RED is not the best choice for everyone, but it is actually a complex and useful invention (I can only say that now). The RED will be attached while you're in surgery, so you won't feel them put it on. You'll have some screws that attach the halo-like device to the head, and pins and/or wires under the skin , attatched to the skull. These connect to a vertical crossbar that runs in front of the center of the face. A lot of this depends on your case.
After the surgery, you then start turning the screws with a special wrench, that gradually advances the midface forward (I know it sounds awful, but it's not as graphic as it sounds). You continue to turn at the pace that your surgeon 'prescribes' for you, until the goals are accomplished.
Does it hurt? Yes
Is it absolutely excruciating pain? No
Does it hurt as much as the traditional way? Probably not.*
Does it get a better result than the traditional way? Usually, yes.*
Do you heal faster?Usually, yes.*
Will you have to have the RED done as many times as the traditional way? Usually, no.*
*I say usually only because I've only had this done once, so I don't know if you will get the same results as me.
These answers are based upon what I've experienced and what I've heard from others.
