Bit on the upper lip by a dog and lost a chunk of my lip. What might be some options for restoring lip symmetry? (Photos)

I’m 25 years old, female. Almost a month ago I was bit on the upper lip by a dog and lost a chunk of my lip to the left of my Cupid’s bow. Since the piece of lip would not be recovered, the plastic surgeon at the ER sewed up the hole, making a vertical line. I know it is too early for intervention, but very clearly my tubercle is slanted and the left side of my upper lip looks flattened. What might be some options for restoring lip symmetry without reducing the other half of my lip?
