Swelling after nose surgery! Silicone height replacement ㅠㅠ Those who had it done ㅠㅠ

After suffering for 8 months due to my forehead! Avatar, I'm so touched ㅠ ㅠ Hehe The director said he'd do a second surgery! Do you still not like the shape of your forehead? He 'll lower it. It's a very simple surgery that doesn't even take 10 minutes. They'll just put a little bit on the side, take it out, shave it, and put it back in.!! I was so happy to hear that and came home... Is it really a simple surgery? ㅠㅠ Oh, I also had an issue with my forehead height being raised, making it look thick, and the width of my forehead , but if they shave the silicone and put it back in, how can they shave it so precisely in such a short time? And will the width of my forehead also decrease? And they said there would be a lot of swelling for a week... but it will return to its original shape in a month. Is it true that there won't be a lot of swelling because the silicone was replaced ? ㅠㅠ ?
