At your age, it is unlikely that braces will have a significant effect on your skeletal/facial structures. Based on the pictures, I don't see a skeletal discrepancy significant enough to warrant jaw surgery (although it's difficult to tell what your bite looks like - it appears you are posturing your jaw forward). To get a definitive answer it is best to have a consultation in person with an orthodontist and/or oral surgeon so that you can be accurately diagnosed and presented with options.
