Is A Sliding Genioplasty A Good Choice For Replacing An Unsatisfactory Chin Implants?

Q: Dr. Eppley ,I am initially thinking of replacement chin implant but now preferring sliding genioplasty instead. Attached are my pictures. I already have a small sized standard extended anatomical chin implant from i planttech. I like the jaw contouring on profile given by the wings of the implant but dont find the horizontal and especially vertical projection enough. 

I havs also attached the initial assessment given by the surgeon on the vertical and horizontal deficiencies. I also have my before chin augmentation pics if required.

A:While a sliding genioplasty can be very effective at adding both horizontal and vertical lengthening it will by the forward bony movement make the chin more narrow.  That is the one dimensional limitation of the sliding genioplasty.  I mention it because you commented in favorably on the wings of the existing implant that you have. That chin feature is what it essentially separates the sliding genioplasty from a custom chin implant design when there is any amount of vertical chin lengthening needed.
