How does upper jaw surgery work + side effects?

[Guest guest]

I saw a surgeon and he said he thought I'd only need upper jaw surgery to

correct my

openbite. I would need upper jaw advancement + widening.

(I have a class III malocclusion, but it's combined with a crossbite)

Before deciding if I want to have this done, I have many questions and it's hard

to get the

surgeon himself on the phone to answer them:

-I understand numbness is quite common. The surgeon downplayed it a lot saying

it's

only happened in less than 3 of his thousands of surgeries performed. What kind

of

numbness is associated with upper jaw, and does it go away?

-Do most upper jaw advancements/widenings use titanium plates/screws and how big

are

they? where do they go?

-What is a *realistic* recovery time for this procedure in terms of when I could

go back to

work and (importantly) speak normally? I am 23 years old and in pretty decent

shape.

Is there any good technical/medical guide talking about the effects of upper

jaw?

Thanks!
