Dear Sean,
Thank you very much for your contribution.
However, Your comments on how your U Shape has been exacerbated by the chin wing concern me a lot.
I will have the same surgery of OP around the same time.
Sean, are you happy of the surgeon you chose? Going back would you change him?
Thanks
You have to think about it logically.
Start with a U-shape that is recessed. It's going to look less U-like the more of the rear end of the shape is hidden. Advancing the entire U will pronounce its shape.
It all depends on your starting point. What shape is your mandible to begin with? To what degree can you flare the rare angles of the jaw? How broad is the front of the mandible such as chin? All these are going to contribute to the end result.
I would just say get a chin wing, see how you end up. If you really care that much you could get the bone shaved down to form a certain shape. Such things are commonplace in Korea, and therefore well within the realm of possibility.
On that note I should stress that it seems unlikely anyone ever gets just one operation and is completely content with the result. More often than not, based on my time on forums, it requires a degree of tweaking afterwards with the first operation(s) laying the foundation of what's to come next.
I'm optimistic that I'll be content with this single operation given from an aesthetic standpoint it's only my lack of chin projection that is a concern. Everything else is fine-tuning. My gonial angles, ramus length, and jaw width are all decent.
I believe Sean's result is very good, especially given it is attempting to conceal functional issues with his occlusion. If I was to be super nitpicky I would say he could benefit from a chin visor osteotomy to improve the sublabial fold, however as it stands he's well within the realms of what is considered normal. Besides, such an operation would be cheap and easy to perform if he ever wanted to go down that path.
The best chin wing results I've seen were performed either at the same time as other operations to correct bite, or on someone who already had a decent occlusion. When the jaws are malpositioned I think surgeons are limited with what can be done.
