Medpor Chin Implant Removal and Sliding Genioplasty Replacement
Q: Dr. Eppley, I had a Medpor chin implant placed several years ago but have never been that happy with it. I have always felt it was not enough and was too short even though the implant was a large. I am thinking of having it removed and replaced with a sliding genioplasty. Is this a reasonable plan?
A: The critical question in your secondary chin augmentation inquiry is whether you would leave the existing chin implant in place and do the cut above it and carry it forward with the sliding genioplasty or take it out and do the whole chin advancement with the sliding genioplasty alone. It depends on how much more your chin needs to be advanced over what you have now, what the thickness of your bone is and whether the bone alone can make the amount of advancement improvement that is desired. That would require a 3D CT scan to help make that determination as well as measurements of how much further your chin need to brought froward to meet your aesthetic goals. If the Medpor chin implant was a large one it may bee doubtful that a sliding genioplasty alone would be able create your ideal chin augmentation result.
