lateral projection are a bit tricky...
mostly for 99%, during mouth opening, you will have soft tissues deformation (not big) between zygomatic arch and border of the jaw
Rather you should not move more than 3mm laterally because of sunken eye issue - too big orbital volume.
More then 3mm might be a bit tricky for the eye even with orbital floor augumentation (resorbable sheet)
By moving the zygomatic bones forward on both side, you get more width at the same time - probably no more than 2mm (I'm not sure), because of the zygomatic arch shape.
Keep in mind that when you move your zygoma for example 7mm forward and 3mm outward, then in summay it will look like you had 5mm lateral projection and 5mm in lateral is very noticeable
LF3 is for forward movements, so You would need kinda modified LF3, which is much more difficult thing
Lateral projections are more criticial than the ones in forward direction for soft tissues including the muscles - for example masseter muscles
However when it comes to postop soft tissues asymmetry caused by lateral movements it's not a big deal when you do it on both sides. In such scenarion it will be the same "asymmetry" so it will symmetrical
Mostly it's gonna look like, during mouth opening, your masseter area will get more in width , but the frontal area - the soft tissues on the sides between chin and masseter muscle (buccinator area) does not change. They will behave like you had the old zygoma positions.
To understand this, open your mouth widely an you will notice that masseters area on the back (near the ears) gets more in width, but frontal gets more kinda narrow or at least does not change
When you move your zygoma together with the masseter muscle (no other option) laterally the posterior part will get much more in width during mouth opening, while frontal part (near chin, and buccinator) won't change (perhaps a bit after many years)
So it's gonna be that kind of soft tissues asymmetry..so it depends on the patient if this is asymmetry for him or not
Hard to explain
