Cheekbone surgery: Scalp incision or incision in the mouth, sagging?

Hello Yesa
 
, I am contemplating whether to get a clown (type 1), cheekbone + square jaw + cortical bone? removal (2.5 types like this), or get rid of it due to concerns about side effects (sag). Here is a
 
front view using the rear camera. If you take a picture, your face is really wide. Because it's that japchae, it seems like a clown is a must ㅠ.. I'd rather just have a bigger chin and just keep it in moderation..ㅠ
 
I've been talking for a long time, but anyway! At this point in time when I was contemplating cheekbone surgery, I looked up numerous articles and found that cheekbone surgery is generally done through an incision in the scalp/inside the mouth. For me, the contouring surgery is done through the inside of the mouth, and since there are no visible scars, I naturally thought that an incision inside the mouth would be good. That's it... But I heard that if cheekbone surgery is done through an incision inside the mouth, the sagging is worse than through a scalp incision? Maybe... Scalp incision - to remove side cheekbones, mouth incision - to remove 45 degree cheekbones?
 
+ And lastly, excluding cheekbone surgery, would it be possible to achieve a slimmer appearance from the front just by performing square jaw + cortical bone removal? The side effects will be less than those of a clown, right?
 
As I write, I'm full of questions... I have so many questions about outlines haha... Thank you for reading this long post~!
