How Much Vertical Lengthening Can Be Achieved With A Bony (Sliding ) Genioplasty?

Q: Dr. Eppley, Hello, with a sliding genioplasty and a chin implant, what’s the most amount of vertical length you could reasonably add to someone’s face?

A: My experience has been that 10 to 12mms per vertical opening wedge bony genioplasty can be achieved in a single surgery.  This leads to uncomplicated bone healing.  I have done a second stage opening bony genioplasty for one patient to ultimately achieve a 20mm total vertical chin lengthening. An implant can not be used with a vertical lengthening bony genioplasty.
