LeFort III requires a coronal incision, which is usually not visible especially with her hairstyle. If it is that visible, no one would do a rhytidectomy either.
And yes, there are intraoral approaches only but I thought only for LeFort II via piezoelectric devices (distraction osteogenesis).
To the thread: Yeah, you can't really fix ugly, there are some rare cases where it actually happens but you can't count on it. Worst thing is to be deluded and actually expect that it will change anything. It doesn't.
its true unfortunately if your guys odds are with all the surgery in the world u wont be attractive BUT you can still improve yourself tremendously . an example is I was born naturally with a bird nose. wasn't really that big but very very curved beak life, huge drooping/goopy tip, wide alar etc. people used to call me pigeon,bird,penguin etc(on top of generic ugly also). now after my rhino no one ever calls me bird like anymore. so although im still ugly I do feel better shedding the bird label.
you have a better chance of improvement (and risk also)with bone surgeries than implants and other ps fixes. when I first came onto cosmetic boards back in the early 2000's many ppl who had serious flaws mainly in jaw chin. so back then people would run off to r. y ,r,t,r and get jaw,chin, cheek ,sometimes orbital rim, necklift etc. they would look a bit better but they would still look off. then it came out that they really needed maxfax but it was too late because they had medpor. on the flip side maxfax has really taken off since 2005 and the ppl getting it (assuming successful outcome) do look much better than the groupwho go with implants or fat etc.
