S.,
I had this surgery done 20 years ago. It was the best thing I have ever done and I do not regret doing it for a single moment. Since you asked, I'll share my experience with you.
I had both jaws done at the same time to correct an extreme overbite. I consiously and reflexively held my lower jaw forward so I would look normal and could eat, but was having bad headaches and my jaw popped so loudly when eating that people next to me could hear it in the High School cafeteria. The original plan was to move my lower jaw forward 8 mm and align the upper to match my bite. That would leave me with my jaw banded shut. But they warned me that there was a possibility of having my jaw wired shut depending on what they found when I got in there. After I was completely under anethesia they redid measurements and had to cancel the surgery after mine because they had to move my lower jaw 11 mm, which would require 3 cuts on my upper jaw instead of the planned 2. This also meant I was wired shut instead of bands. I came out of anesthesia vomiting blood (sorry if that's TMI) because they didn't have me positioned correctly and so the blood was draining down my throat into my stomach. That was the most horrifying part of the experience -- mostly because my jaw was wired shut. I spent 3 days in the hospital. I had to beg for a pain shot the first night because the pain was so bad. After that I made sure they kept on schedule with pain meds. I stayed home from school for 4 more days, but went back on the following Monday because I was bored. Most of the bruising was gone by then, but my face was still swollen. Since I was wired shut I couldn't really talk (wired shut is nothing at all like trying to talk with your teeth clenched together. with wires talking is nearly impossible) so I carried a paper and pen with me to communicate and got really good at hand gestures. Also with wires it is a strictly liquid diet, not soft foods. They took my wires off after 4 weeks (instead of the planned 6) because I had lost too much weight on a liquid diet -- at which point I had those teeny tiny bands on every tooth. Much better than wires! (With only your lower jaw being done, this should be what you start with.) I pretty much resumed normal life when I went back to school, but I was careful to not get bumped in my jaw and was excused from phys ed.
I have 2 metal pins in my lower jaw and 3 metal plates in my upper jaw. Anytime I get a new dentist they always ooh and ahh over my x-rays. I haven't noticed any pain with my pins or plates associated with weather changes, although I can feel the plates through the roof of my mouth when it's really hot or really cold. I can always feel the pins in my lower jaw.
I also have residual nerve damage: from my lower lip to the bottom of my chin, about the width of my lower lip I have limited feeling. It doesn't bother me unless I think about it. So it's not "numb" feeling, I just can't feel things as well as I can on other parts of my face.
My tips for you:
- talk with your doctor about all the possible outcomes for your surgery, both best and worst case scenarios. Tell him what your expectations are and make sure they are within what he/she expects as a reasonable outcome. Make sure you ask if it is at all possible that you will end up wired shut instead of bands. If so, you'll need to be prepared with stuff for a completely liquid diet. Write down all your questions before your next appointment with the doctor so you'll be sure to ask them all.
- be prepared for it to be painful. Like I said, this was the most painful thing I have ever done (before or since). Find out what your options are for pain medication and enlist the help of your husband or other helper to make sure you take it on time.
- you will need help with your kids for at least a week after you come home from the hospital. Especially with your smallest one since she won't understand not to touch/hit/"help" mommy's face. Whoever you have helping with the kids, make sure they are ready to help you too.
- record/rent/buy a bunch of videos, books, magazines, etc to keep you from being bored. You'll want to get up and go before you are really ready if you are too bored. Pace yourself so you don't overdo it.
- explain to your older child why you will look bruised and swollen and that it will take a while to go away. If she understands the what and why of your surgery (on a five year old level of course) it won't be scary for her
If you have any other questions, feel free to send me a message. Good luck. I hope your surgery has a great outcome for you.
