Well at least you've tried that you can discount weight as an issue. However having a chubby face doesn't mean you have skeletal issues. You could simply be holding a lot of fat there which should improve with age.
To be honest nothing about your face strikes me as being particularly off.
You could always consider buccal fat removal, as risky as it is.
Yes, I guess the fat issue could potentially improve with age, although i'm not confident, and I don't really want to wait until i'm old to feel happy in my skin.
The orthos I saw confirmed that I did have a slightly recessed lower jaw - although both suggested that it wasn't severe enough to warrant jaw surgery and advised against it. Also a deep bite with a unilateral crossbite
From head on, my face looks a little jowely/heavy to me. Mouth looks downpointed and maybe a little 'sad'.When I give myself a 'facelift' by pulling the skin around my cheeks upwards, I look so much better. My chin and cheek look defined and I look normal.
I don't know what operation (other than a facelift!) could mimic that sort of result, though! ?
I can't wait to speak to an expert in facial matters. I've realised it's a bit of a waste of time talking to orthos about anything other than straight teeth. (at least here in the UK)
