Hehe, my sister had, at age 16, a palatal expander installed one week, and had her tonsils and adnoids out the following week. Talk about agony. Her face already hurt before surgery. She had to learn hoe to swallow differently, since she had a plate in the way in the roof of her mouth. Not touching the roof, mind you, but near it.

All that pales in comparison for what was in store later. They broke her bottom jaw and removed .25 inches of bone from each side, and sawed her upper jaw off and pulled it forward .25 inches. Follow all this up with wiring her jaw shut for 6 weeks after. -=shudder=-

All of this was to correct a fairly extreme underbite. Thank goodness she's all fine now.
