My chin looks too big post sliding genioplasty, is a reverse sliding genioplasty or burring the chin bone the best solution?

Question

I had mandibular advancement for an overbite 17 months ago. My surgeon has retired. My lower jaw was moved forward 5mm and then my chin was moved forward another 5 mm with a sliding genioplasty. The genioplasty was also jumping meaning my chin was slid on a slight upward incline. However, my chin now looks too large. It is extending horizontally past my lower lip and the chin bone also appears too wide.Also, my lips have thinned a bit. Is a reverse sliding genioplasty the solution?

This is something I see fairly frequently. We should have a number of options including reshaping the bone wherever is necessary to improve your appearance.  Watch our videos to learn more.

A true jumping genioplasty is more challenging to reverse in that the chin bone has been overlaid completely on top of the uncut chin bone above it. Usually this would not be possible with a 5mm movement as the chin bone is much thicker than that. So I think you have a more typical sliding geniopalsty that was moved 5mms up the incline of the bone cut. It would be better to either partially or fully reverse the chin bone movement rather than trying to shave it since you have a combination of dimensional issues (too far forward and too wide) that need to be addressed.
