Caucasian getting a v-shape jaw line through jaw shaving. Is my wish pic realistic? (Photo)

The photo you have shown beside yours is not realistic and I'm afraid you will be disappointed with results, if this is your expectation.The shape of your jaw can be altered and improved somewhat, but you can't change the lateral width of teeth in lower arch and position of your condyles in the fossa. This young ladies photo is someone with a very petite face and pointy chin. You need to see your surgeon and get some before and after pics that are realistic and give you an idea of your outcome and see if it worth the surgery for you. Good luck

yes, the face shape can be 'softened' with a V-line surgery, which is quite common for some of us to do; and the chin is involved as well to create the 'look' of the image you prefer. The overall facial balance has to be considered so that xrays etc are advised for the planning process.
