I'm sharing my jaw & chin recontouring and tracheal shave experience performed by dr Chettawut with you dear users of this forum, as more of a lesson than anything.
Overall, I regret choosing Chettawut. He is an amazing, sweet kind person, his staff is extremely professional, polite and my journey to Thailand was a true blessing. I chose Chettawut as I had this idea in my head, based on my prejudice as well as on what I've read, that him as well as Suporn, two top thai transsexual surgeons, are BEST at shaving Addam's apple, which was my biggest, biggest concern. I have experience getting clocked for it, and it was not a pleasant experience.
I was fully aware that this type of surgery has limitations, you can't just start shaving to your heart's delight, but I was hoping my Addam's apple won't be as visible I presume. It's still very much prominent. (see the pic at the right, I know it's a bit in the shadow, but you can still see my addam's apple when I look straight ahead and don't even move my head)

I also did my chin and jaw re-contouring as I wanted it to be done well, perfect actually, and I was thinking, what, apart from addam's apple, is the thing I don't trust other surgeons with. I had a really wrong idea in my mind as to this type of surgery, I was thinking it'll change a bit more in my face, that it'll change my proportions, I had my hopes high, but all in all, nothing changed. Nothing changed because even though my jaw and chin was fairly prominent, its prominency prior to surgery was a mix of bone structure and fat distribution, now that the bone has been shaved, my face shape is identical, but I just have less definition in my face contour, in the sense that You can't see my jaw angle, unless I look up, it's just fat and skin now.
I didn't look at jaw and chin contouring as a feminising surgery, as then I'd appreciate lack of contour in this area, it's much more common in women, but I looked at it as a beautifying surgery, wanting to achieve the V-shaped jaw & chin.
Here I'm lifting my head up as well as bringing my jaw and chin slightly forward to reveal the outcome. It's minimal. It's really minimal, and I was hoping for more.

Now, some positive aspect, lol! My chin. From a square, quite bulky chin it went to softer, less pertruding, U/V-shaped chin. It's only visible when I smile though, which was my concern, my smile is ruined by two things a.) my chin b.) my nose. I am quite happy with the outcome, but I said to the doctor, as well as showed him pictures, where I pointed out I want a V-shaped chin, and to be honest, I don't see much of a difference in my chin and chin of other of his patients... I have to have a look at his website one more time, but I'm pretty sure they're identical, which means my point was ignored.

When I lay down, i.e. all the skin that usually is around my jaw and chin goes up, and you can truly see the bone structure, I can see quite a big change, but don't get your hopes up, when I look straight ahead I look literally the same, the change is minimal as I mentioned.

And here the front pic:

The final thoughts:
If I could turn back time *cher voice*, knowing Chet wouldn't remove my entire Addam's apple, and my jaw&chin is not gonna be as spectacular as I thought, I'd choose either dr Bart from Belgium or dr Cardenas, being really pushy about carving a V-shaped chin. Plus they're
SIGNIFICANTLY cheaper.
Good luck!
