I saw the surgeon today for the one-month follow-up and we discussed the whole surgery in detail, including mid-face support etc. and I'm now even more convinced that what he did was the best 'solution' for my particular case. He confirmed that the cheek and upper lip areas are particularly swollen, probably because of the HA, and that the nasolabial folds should become a lot less deep when the swelling goes down which will probably take months in my case. He also suggested some possible solutions in case I'll still not be 100% happy so I'm now more relaxed about the whole chubby cheek thing.
On another note, I want to take this opportunity to thank you - GJ, kavan and Lazlo -, I vaguely remember we had some silly disagreements in the past but today I just want to say I'm really grateful because when I first came across this forum, I did not know even basic things about jaw surgery and I got so much useful information and advice here, from many people but particularly from the three of you. Without that input, I don't think I'd have gotten the surgery and / or not with this surgeon, and now it's done I'm so happy, I'm kicking myself for not doing it years ago. Luck had probably been on my side too but I haven't had any complications so far, my breathing and bite is so much better than before it's amazing, I look better, I just feel so much better overall and it was so worth it for me. Thanks for your contribution to that.
