Sorry Mili I haven't seen your answer when I've post
.... I'm asking a lot of questions about upper jaw extrusion, because a vertical growth is not a good thing, so why doing it ?
I was told it restores vertical dimension but it happens under the nose.
Benjamin has the chance to have normal orbital rim but for a lot of people, I think the vertical dimension has to be restore under the eyes. Under the nose may worsen some people's face.
(I hope my english is comprehensible and my post relevant !!!!!)
