Let us know which procedure you decide to go with. And keep us posted on the procedure and the healing - (post lots of photos) - I am interested to see how it is done.
And REMEMBER, no matter what it looks like immediately after the surgery, it will NOT look like that in a few months! What you are talking about having done is not going to involve cutting and re-sectioning any parts of your skull and they are not going to be cutting through any significant muscle mass, so it will produce little swelling. Also, your scalp is very vascular, so it can carry away excess fluid quite quickly. You might have a little swelling, and some bruising, but I'll bet that you will heal up in less than a month. After that, just keep up with the scar cream and you will be amazed how that little scar will fade away over a few months time!
When I was your age I had my right eye orbit moved forward and my nasal bone rehung on the front of my face. They purposely did NOT put my nose on straight. They put the top of the nose right between my eyes and hung the bottom of the nose centered over my Cupid's Bow. (I'll bet you didn't even notice that from my photo! If they had hung it straight down it would not have been centered over my mouth! That would have been noticeable!). I looked like a train wreck for about three months and it did, in fact, take a full year for every bit of the swelling to go away. But at that age, the skin retracted and healed up just great! I am so glad that I did it! It made me feel better about myself - and that is what matters!
I am really happy for you!
