Can sliding genioplasty be done at a certain angle? (photos)

The angle of the sliding genioplasty will vary depending on the anticipated results. For severely recessive cases, the horizontal osteotomy is made with maximum advancement in mind. A more vertical approach is taken when less advancement is needed. You seem to have a deep mentolabial fold and may require vertical lengthening.

The great thing about a genioplasty is its versatility. The chin segment can be moved up, down and even to the side; it does not have to just come forward. The example photo to have is very much doable. It is all about facial balance. Our office offers in-person or virtual consultations if you would like to discuss options further!

There are definitely choices in which direction the bone segment should be advanced with a sliding genioplasty. And some individuals they need forward to projection, while others may need augmentation in a more vertical direction. In your case, you already have a good forward, projection of your chin and pushing the chin segment, further forward will create an abnormally deep labiomental fold.
In your case, a more vertical augmentation is probably better.
I’m not completely sold, that you need a sliding genioplasty.
