Sliding Genioplasty and Deep Labiomental Fold
Q: Dr. Eppley, I was looking through some of your before and after pictures for sliding genioplasties, but could not find something I was looking for in particular. I am just wondering if you do sliding genioplasties on patients with a convex chin (moderately deep labiomental fold)? I have a slightly convex chin, which is especially true when I bite down due to a slight overbite. My chin is fairly recessed (15-18 mm), but I don’t intend to make it perfect, an 8mm horizontal projection would be adequate based on some of the morphs I have done. I am just wondering is it even possible to get an 8 mm projection with a slightly convex chin, without acquiring a “witches chin”?
A: An 8mm horizontal projection increase is fairly standard in sliding genioplasties in my experience. Whether that avoid your concerns of a ‘witches chin’ is hard for me to answer because I don’t know your definition of that term. In the medical sense that is a soft term used to describe a sagging soft tissue pad which is not a phenomenon ever seen in a sliding genioplasty due to the enhanced bone support that naturally occurs to the soft tissue chin pad from the procedure. It will, of course, deepen your labiomental fold.
