I realize most feel I'm not a candidate aesthetically but I want you guys to look again at my morph and tell me if you still feel the same.
I did a morph predicting STRAIGHT MMA without genioplasty. I first slightly CCW rotated the lower half of my nose to the bottom of my upper lip since that soft tissue should rotate CCW even with straight advancement since above the advancement will naturally rotate. This includes desireable upper lip projection and undesireable nose upturn. Then I advanced from the top of the lower lip on down straight horizontally. Finally, I pulled the lower lip in a bit since I think it won't curl out so much after mandibular advancement.
This is the result. I roughly measured 10mm advancement at the chin by sizing my cephalometric x-ray to my profile shot and using the ruler on the ceph machine to compare the space between before and after. I've also posted the photo I used to do this. I realize it's probably not exactly 10mm, but I think it's close, say within 1mm either way.
I'd also hope that my jawline would pop slightly more with the advancement due to tightening skin, but I didn't try to create that effect.
Further questions:
1) Is this achievable/realistic? Did I underestimate the amount the top of my philtrum will advance (i.e. under-project "chimp lip")?
2) If it is achievable, how does my morph look? Do you think it looks better than my current profile?
3) Is 10mm bimax considered a large advancement? How much could I expect this much advancement to affect my airway?
If you guys think I'm crazy, well, let me know that too I guess.
Hi, from my knowledge soft tissue cannot be predicted with too much certainty, it's unfortunate but no morph is perfect because of that. The surgeon can put your bones in the position he wants down to 0.1 of a mm, but he cannot predict the soft tissue to such a degree. However some things are to be expected, your nose should widen but not upturn so much, I've seen hundreds of before and afters and no nose has upturned that much, most of the time the tip stays in the same place after swelling goes down, but the alar almost always flares and lifts a little bit. That's also somewhat bad but in my case my nose is pretty narrow so it's not a big problem.
My nose IS naturally upturned(genetics, my mother and dad are the same) and it scares me a bit that it may become piggy but my surgeon said he can control it and in fact his patients looked fine after it. Worst case scenario I get a derotation rhinoplasty as an upturned nose is terrible for a guy.
Your morph looks better, except the nose, but I think surgery would be even better because your jaw would pop out more and the upper lip would probably be a little more forward than the lower one. I think it's not properly rotated. Moreover the cheeks seem to pop out more after a lefort I advancement because some of the muscles in the cheek are attached to the lower maxilla.
Look at this cherrypicked example(the girl is gorgeous):

See how her cheeks are more prominent now, the line is almost near the mouth when she smiles.
10mm is a large advancement but you also need to consider the original size of your bones, only the surgeon can really determine it.
About craziness...jaw surgery evolved a lot in the last decades, it's very likely since your bite is fine that you will not need to stay in braces for years and most likely you will only need rubber bands, not wire shutting your mouth and eating through a straw for months. Advancing both jaws is also much less likely to relapse than setting back the lower jaw.
Having said that, it's still a pain in the ass but after a few years you will not even remember it.
Now, you cannot become too fixated on that, you're a normal looking person to begin with, it's not like you have a major deformity, if you think your face right now is creating you tons of problems it's most likely in your head. Somebody with Crouzon or a severe under or overbite can suffer discrimination, people staring, and so on, it's not your case, your face blends in the general population.
I also realized you may have a slight negative orbital vector, it may get somewhat better after surgery or you could look into infraorbital implants or a lefort 3(but no doctor will do it in your case). That will also give your face a sunken look if that's what you want to fix.
