I decided to get chin surgery (chin advancement)

I've been to both ㅁㅇㄷㅇ and ㄴㅌ before, and both recommended osteotomy for consultation.
 Just in case something different came up, I recently got a consultation at ㅇㅇㄱㄱ,
 but they also talked about chin advancement. I don't think I should get an implant because of my condition!
 
So I decided not to look into it any more and just get chin advancement.
 Out of all the ones I've been to, ㄴㅌ seemed the best, so
 I'm trying to make an appointment for them, but should I avoid the summer?
 
Since I sweat a lot, I'm worried that the sweat will cause irritation after the surgery and that
 it'll be worse. I'm thinking of getting it done in the fall when it'll be a bit cooler
 . Is it okay to get the surgery in the summer without any surgery?
 And
if I only get type 1, how long is the recovery period?
 Even though it's only type 1, since it's osteotomy... I think it'll take some time. How long did it take everyone?
