Thanks for taking the time to reply. To be honest, you've opened up some possibilities that I hadn't previously thought about but not sure I would know where to start.
When you say upper jaw widening, do you mean or include in that SARPE? I did ask my orthodontist about whether I could get SARPE without jaw surgery to correct my bite and he did say it would be worthless in my case. However, I didn't really question him about this in detail so I'm not sure why he thought doing this procedure alone wouldn't be a good idea in my case.
I'll be honest, the idea of any type of implants doesn't really excite me. The tongue tie issue I had never really noticed before. But it's definitely interesting. Do you see my chin/lower third appearing shorter if I 'untied' (is this the correct phraseology?) my tongue?
Yes, by jaw widening I mean SARPE. It's also called palate expansion, and there are other acronyms as well. SARPE is usually is a little more invasive in that they make surgical cuts under anesthesia similar to upper jaw surgery. It can also be done in a minimally invasive fashion where they just make small punctures along the palatal suture instead of sawing it open with a bone saw. They have their pros and cons. I'd just stress the importance of using a European type expander that I linked to as you will get twice the amount of expansion using that method within the same amount of space and it just looks better because it keeps the teeth from flaring out unnatually. At least in the US most orthodontists are not familiar with it though so you might have to ask around or specifically request it. It takes some experience to get it right though. Being in Europe maybe you want to visit that Belgien guy Joel Defrancq. I've never seen him mentioned much on these forums. He claims to have popularized that type of palate expansion but I don't know if that's true or if he's well regarded as a surgeon here.
With regards to the tongue tie, this is a good example of what it would look like if you are in fact tongue tied.

If your chin sags in pictures it might create the illusion of a longer chin and this might help. I'm not really sure but regardless it usually looks attractive to have a well contoured and taught underside of the chin. You will see people recommend myofucntional therapy with tongue tie surgery which in my opinion is nonsense. You just need to stretch your tongue like crazy when it's healing.
I'll admit the conventional approach with you would be to shave down the chin a little and do a genioplasty like the doctor sketched out for you. You could then advance the jaws a little too without having your chin stand out. I feel like that's going to be a lot of shaving in your case though. Shaving down the chin in very popular in Asian countries. It's even what Kylie Jenner did and she turned out looking quite nice. I'm not sure if she was quite as bright afterwards but we won't go there. Hopefully the advancement compensates for the loss but it seems dangerous to me to mess with the part of the face where the tongue muscle literally attaches to the chin bone.
I think what particularly catches your eye with regards to you chin profile other than the size is you do not have a Western European style point on your chin. I think that's why in the picture of your proposed genioplasty you see the doctor rotating the chin bone a little to get you that kind of point at the end. That kind of has become the aesthetic ideal but I think what you have is a natural variation that just isn't as popular. I notice people with this variation sometimes have a forehead that slopes back a little bit at the top like you have. They kind of work together. You might want to make sure changing the shape of your chin doesn't mess with that harmony. Sometimes there are little things like that at work that we don't notice.
I also feel like you just have an absolutely perfect smile that is situated just where it should be to show the right amount of tooth show. That's rare and pretty special and it's not usually something even the best doctors consistently get right with jaw surgery. I think if you move your jaw up your going to look worse because you're not going to see your teeth when you smile. There is a guy on a forum that posted recently that did just that and he really seems to regret it. So be careful. I'm very confused about why that is being recommended for you. Moving the jaw forward doesn't seem to expose that much more gumline when you smile compared to vertical movements up and down.
Most people that get jaw surgery for recessive jaws also have sleep apnea. The fact that you don't kind of is a hint that you don't really need it. The reason I mentioned some of the theory around why size is ultimately more important than shape in jaw structure is because I feel like you're kind of a case where if you could come to believe the way you look serves a nice purpose you might come to appreciate it. I don't really look at you and think "she needs jaw surgery" like I do a lot of the other posters with sleep apnea on here. What you have might just be a little better than you realize, even if it's a little different than the norm for women.
I am curious about the so called lip incompetence you mention. I don't think it looks that bad either, but I am curious what do doctors or posters here attribute that to? I've never really understood the mechanism behind that.
