I have exactly this same problem. I had a mentoplasty, which I thought would help, but it didn't do much. I've thought about jaw augmentation, but I don't think that's really the issue, either. My throat/tissue/whatever just sits relatively low in relation to my jawbone. I also asked a facial surgeon, and he said the same thing about liposuction; I'm young (29), so I don't have any fat or loose skin there to remove. I hate it, but I'm just not sure if there's any solution. I'd love suggestions.
