Would lip fillers help in improving the lip shape? Is there lip reshapement surgery that will accentuate a cupids bow? (photos)

In September, my dog bit my upper lip. I had an amazing plastic surgeon operate on me. But I have completely lost my Cupids bow. On the left side of my upper lip, it's lower and more taught because of pulling the sides together to close the wound and I want to know how to correct it. There's definitely scar tissue inside the upper lip that I have been massaging to help but as the swelling went down the shape did not change. I'm heartbroken.
