Questions on genioplasty techniques

[Guest guest]

I've seen the genioplasty technique on various websites where the

chin bone is cut diagonally, however, it seems to me that this

technique involves shortening the vertical length as well, since the

cut was made on an angle. It also makes sense that the farther the

projection forward, the more the chin's length is reduced

vertically. For someone who desires an advancement of 8mm

horizontally this doesn't seem like a good technique if the person

is satisfied with the vertical length of their chin.

Are techniques that move the bone only horizontally well known to

most oral-maxillofacial surgeons?

I appreciate any advice or experience.

Thanks.
