in a way, it can. if you have a short midface a horizontal lengthening can pull and tighten the soft tissue, as is the case for lefort 1. if your midface (maxilla) is short/recessed the soft tissue tends to bunch up around your zygomatic body, and pulling it forward can help accentuate them. the osteotomy dosnt mobilize the actual zygomatic complex, but gives the illusion that theyre more defined. it can not add actual projection.
