What are my surgery options for extending out the area that I've indicated? (Photo)

I had a chin implant a couple years ago, but I still feel like my chin is slightly recessive. I believe my surgeon chose the best implant that gives my chin a natural look without making it too long, but the only reason it would be long in the first place is because of the area right below my chin. How can this area be altered? Are there implants that are bigger in height that could've added coverage to this area as well? Thank you in advance for your time. -Sarah
