I was fooled by the sweet words that said if you cut the bone and put it together, you will get a V-line, so I had the surgery, and it started sagging just a year later. The nerves in my gums haven't come back yet! The texture was gone and it was crumbly... I ended up having a face lift. If you have decided on facial contouring, you need to be prepared for a lift. Even if I only tried double or thread lifting on the arm, it was ineffective and I ended up having to get a lift. Now that I have a lift, I finally got the V-line and B-shape I wanted, but there is a scar inside my mouth. Dull gum sensation. The scar in front of my ear... it's bittersweet.
