Severe hawks like me must have osteotomy unconditionally, but there are a lot of people who think that osteotomy is bad.. But so far, I have no problems and I love that the hawk escaped! In the case of swelling, it was definitely a surgery that required a little osteotomy, so it seems that the small swellings are going away for a longer time than I thought, but I was able to tolerate it because I could see it disappearing day by day. Also, it seems to be thinner than it was a month ago, and the tip of the nose seems to have gone down as the swelling has gone down moderately.
