Leila. I'm happy for you that you have found yourself in the comfortable place with all of your facial features. Seems like you had quite a bit of luck as far as HRT effected your features. Majority don't have any really significant change due to the HRT related changes, other than rounder and overall softer appearance of the masculine jaw. The changings of the noses are a bit of a fairytale, as true reality is most transwomen have very masculine noses, until fixed, which often destroy other overall either acceptable or even beautiful features. Not even 50 years of hrt will change a horrendous nose into a beautiful one.
I had barely visable adams apple once, few years ago, before I started HRT... HRT did quite a lot in that department, first: majority of my neck muscles shrunk down or went away somewhere, and second: most of the fat tissue deposit that I had in neck area did the same as other fat tissue did in my upper body. It happily went on my thighs and hips... Suddenly after around 1 year of HRT my adams apple became very very prominent, to the point that it was the thing that got me clocked. And other than rather small breast, it was the only thing that would get me clocked. We fixed that.
Lucky you if you don't need FFS now or ever. You saved quite a lot of money. However FFS is not always about NEED. For many trans girls and women it's about WANT. I didn't need it, but I definitely wanted it. I never had any masculine features, what was there were androgynous features. So I went for it, and basically deleted any single trace of androgynous from my face. Was it worth the pain and money? F*** yeah! Every tear any every single penny.
Removal of masculine features from your face doesn't make you look weird, it makes you look more feminine.. HRT before or after only helps. In the hands of the right surgeon who knows what he doing, addition of fat, or/and softening doesn't really matter. Even if you gain 50kg after having FFS, will not make you look weird, only really fat, but the feminine features of facial structure will still remain.
To the OP OneWorld... Send a request for evaluation also to some other FFS surgeons. You may hear a different opinion, that could be helpful. Also I didn't ever saw a single good FFS result from dr. Chettawut. I have seen mostly average, and some quite honestly bad. Could I be wrong, and there are hundreds of amazing results that are not shared online because of privacy and/or stealth? Shure. What can be found online, on his page, forums, groups is far from amazing. That's strictly my subjective opinion, and could be very wrong.
