Am I able to get a revision? (Photo)

I am a female who had a double jaw surgery with a genioplasty. My jaw is perfect now. My chin is what I’m not happy about. I was told a KLS chin plate was used. My only concern was my jaw, but I was told my chin was also shifted to the left and my nose too. I agreed to have my chin fixed along with my jaw. My jaw is now perfect, but my chin isn’t. Can I get it fixed?
