Sliding Genioplasty

Q: Dr. Eppley, I had a sliding genioplasty done two months ago and I think that it has shifted. I am not sure if there is a gap on part of it because of the shift. I would like your opinion and evaluation.

A: Thank you for your inquiry. I understand that you think your sliding genioplasty has shifted. Did you have any x-rays after surgery or any now that would help understand if that is what has happened? It is also possible that as all the swelling has finally subsided any asymmetries can become more apparent which are masked for the first 4 to 6 weeks after surgery due to the swelling. Please send me some pictures or anything that shows where you see the chin/jawline asymmetry. It is also more likely than not that the gap you see is the step-off at the tail end of the sliding genioplasty along the jawline behind the chin. This can be more apparent on one side or the other and is more common if the sliding genioplasty movement was significant or the angle of the bone was at least 45 degrees or greater. The bigger the bony movement and the greater the angle of the bone cut, the more likely jawline indentations will appear after surgery.
