Update: so I had a few more consultations and only have one more scheduled, with Dr A in Spain. So far there are two surgeons I am seriously considering and as usual, they have quite different views on how to fix my face.
Dr D from Belgium is confident that I need Le Fort 1 plus BSSO and genioplasty. He says all three are needed and in addition, he also suggested paranasal augmentation with medpore plus PEEK cheek bone augmentation (all in one operation). It never crossed my mind before to use any implants but he sounded quite convincing.
The movements he proposed are: 4-5mm 'intrusion' of the upper jaw and 1-2mm 'backwards' (English is not his first language so don't ask me what he means by that...). For the lower jaw, alveolar segment osteotomy after removing first premolars. By the way, he wants to do surgery first on me and then braces for a very short time only, like 1-2 months to stabilize the bite. He says since my teeth are already straight, they just need to be repositioned.
I stressed it to him that I'm worried about nasal changes and looking older after Le Fort 1 and he kept saying and included in his written recommendation as well that all things considered, the Le Fort would give me the best aesthetic result.
Now there is a British surgeon I've been talking to that made a great impression on me, and he told me that it would not be a good idea to touch my maxilla at all and I would get the best and safest outcome from orthodontics, mandibular advancement and / or genioplasty. He says that my gummy smile is not bad at all and I am getting to that critical age when my upper lip will start 'sinking' and I will be happy I have a gummy smile and tooth show. Which sounds great and I would be so glad and relieved to avoid Le Fort 1, on the other hand though, I cannot imagine ever being happy about my tooth show as honestly, it is just way too much and if I get it 'corrected' by orthodontics, my teeth will still be visible, only they will be inclined backward.
Right now I am really in two minds, both plans are really tempting to me in different ways. I feel very comfortable with the British surgeon, he was very honest with me about the risks and did not try to 'sell' me anything, quite the opposite in fact. He is well qualified and experienced and was very confident saying just moving the lower part forward would be a great improvement and we would avoid the risks associated with messing with the maxilla. His plan is lower risk, but potentially also 'lower gain'.
If Dr D's plan works out, I believe I would end up looking a lot better than now, and probably better than if I go with the British doctor's plan. On the other hand there are a lot more things that can go wrong, medically and aesthetically. It really is like gambling. Does anybody think the plan of moving the lower part only (with or without genio) can actually be a good one, including from the aesthetic point of view?
