I took no umbrage to your response to my initial post.
Thing is when I looked at your ceph, I didn't see an extreme 'angle OUT-ness' (exaggerated proclination of the tooth bearing alveolar process). In the screen shot of slide share photo of bimax protrusion (which incidently, I've come across prior), the extreme outward angulation of the alveolar process of both maxilla and mandible is clearly seen in there. That is to say bimax protrusion is clear as day in the screen shot you entered. Everytime i see those slide share things, they seem to be coming out of non English speaking countries. So, maybe something gets lost in the translation. So, no idea why they said the bimax protrusion wasn't visible in the ceph photo shown of that patient.
Also, in your initial posts, you didn't mention you had prior orthodonture. Although you mentioned ortho later down the line, my respose was to reply #3.
Now, I'll tell you what I saw in your ceph which I didn't mention because I was cross referencing assessments of things I didn't see in your ceph and your mention of prior orthodonture came after I started my observations. There is somewhat of a 'forced downward' chin contour that's common with Anterior Open Bite. In fact your smile shot shows a lot of POSTERIOR gum show which is also consistent with AOB. So, it's quite possible you started with both AOB and some bimax protrusion and the ortho corrected the bite. So, maybe the ortho engaged the frontal maxilla area downward to help close the open bite.
There's nothing 'wrong' with the prior ortho work and the fact that the angles I looked at relative to the type of angles associated with bimax protrusion didn't cross reference enough with bimax protrusion would be consistent with an ortho correction of it. Also, having a gummy smile (where your reference seems to be the FRONT part of it and not the back) possibily could be consistent ortho work bringing down the alveolar process of maxilla.
Basically, IF your 'natural' pre-ortho condition included AOB, although surgery might include some reduction of the anterior maxilla, it might NOT be CCW impaction and instead might be a combination of of BOTH anterior AND posterior impaction with a NET CW (clockwise rotation) where the posterior impaction part of it allows the chin to swing up somewhat (because a long posterior maxilla (lot of posterior gum show to the smile) is what forces the lower jaw (and chin) backwards like I see on your ceph.
That said, the DECOMPENSATION process which is basically braces aimed to UNDO what ortho did prior is with the aim restoring your natural skeletal contour/bite and proceed with a surgical correction of the skeletal imbalance.
ETA: The soft tissue thickness to the lip 'is what it is' (common with some groups). So, I don't see that being reduced.
