Oh I see, so basically its main purpose is to lower the gonial angle? Coz that's the difference I can see
Yes, but lowering the back of the jaw can give the face a broader jaw (from the front), or at least that perception. Because the golonial angle will be placed lower, so it will be more square instead of for example triangle or oval (at least that's the idea and goal behind it).
If you want additional horizontal augmentation, sometimes they push part of the lower jaw bone to the exterior along with the normal chinwing. This is what Stupidjaws did (and he also did boneshaving) but it's a tricky procedure cause you don't know how much bone elasticity you have. If the bone breaks into pieces during surgery you'll need implants to fix the lack of jawangles (which is an additional procedure, more scar tissue, additional costs, anxiety, depression, etc.). Also, it's more prone to asymmetrical results, especially if your face is already asymmetrical. And of course there are the usual other risks like resorbtion of the graft that is used (usually hipgraft) to fill the 'gaps' and damage of the nerve. The younger you are, the better the chances of having small or no complications.
Looks like a jaw surgery case. Terrible lip posture.
Yeah true
