I have so much movement in my chin and it is getting worse with age. I have begun to notice strain in my neck when speaking as well & my lips move a bit unevenly with certain speech sounds that makes me think there might be an issue with my mentalis muscle. I have have Botox in the past and it only made it more difficult to speak. I feel as if there may be an issue with my chin and I might need more support in that area. Am I looking at needing a sliding genioplasty?
