Hi, Madison ~
You're going into the AN surgery with exactly the right attitude; confidence in your surgical team and a positive outlook.
No one can guarantee that there won't be challenges ahead, including the possibility of some facial nerve issues, but that is not a given (
I underwent both surgery for a 4.5 cm AN as well as follow-up FSR - with no facial deficits). Fortunately, there are many therapies for any facial weakness that may develop and for many, facial weakness is temporary, as are most post-op issues. Patience will be needed, even with a great outcome because you'll want to 'get back to normal'. We
all feel like that. The good news is, you will. Just give it time. Some of our members have gone on to ski, take cruises, run marathons, etc post-surgery so the future looks pretty bright for AN surgical patients today.
As you await a surgery date, don't allow the 'what-if's' to dominate your thinking. That road goes nowhere. Instead, envision being post-op, home and recovering nicely, doing the things you like to do with the people you love. That's what I did and it worked out fine, as I'm sure it will for you, too. Lots of folks will be praying for and thinking of you now and on your Big Day, so you'll never really be alone in this. With all that going for you, I hop you'll be able to relax a bit and enjoy the spring weather.
Jim
