You really should put your photos together all on ONE IMGUR link. Absent of that, I will just look at ONE link which is the surgical displacement plan. Thanx though for naming the links so I knew which one to choose.
It looks like a good plan that focuses on addressing some maxillary deficiency and basically allowing your mandible to AUTO-ROTATE (a little) to close the new bite. Lucky you, it's basically a single jaw surgery aimed at addressing maxillary recession.
The plan conveys that the directional displacement vectors of the maxilla are approx 4mm horizontal and approx 3mm downward which is the displacement needed for your mandible to stay ALMOST where it is already but auto rotate just enough to close the new bite.
The proposed movement is a good one. No one on here can get any more accurate that the high tech program used by this doctor to balance the jaws and the bite.
Airway opening is a MOOT point since you probably don't have a problem to the lower airway because your lower jaw is in a GOOD position. It's NOT recessed. Also, you relay your upper air way has been addressed prior.
Sometimes the lower jaw is off centered due to the maxilla. If that's the case, they often do a 3 piece lefort to make adjustments. However, everyone has SOME asymmetry and yours might be within the norm
Movement is to correct maxillary recession so your maxilla will go horizontally outward and down. The 'lefort 1' area is where the movement is. So that is approximately LOWER midface becomes more prominent. Parts of the maxilla above the L1 area are NOT moved; areas under eyes and cheek areas STAY where they are. If they are already recessed and could look RELATIVELY more recessed via the L1 area movement, that can be addressed with some HA paste material so they don't look more recessed.
Maxillary movement in maxfax surgery does NOT change the cheeks nor area below eyes. So, if those are recessed, they might look a little more relatively recessed after the surgery. BUT where the part of the maxilla they actually MOVE is now recessed, THAT PART of the maxilla make your lower midface more prominent.
It is best to wait AFTER the type of surgery you are getting, to get upper face implants LATER on OR the surgeon can use some HA grafts to enhance those areas. Cheek implants could be too much of a 'surprise', perhaps an unpleasant one which is why it is best to evaluate AFTER surgery to put in those things. HA paste, however, is more subtle and can be done so areas above Lefort 1 area don't look relatively more recessed. So, fine IF your surgeon wants to put in the HA paste during the surgery. But NOT fine for what ever one/s wanted to put in cheek implants during the surgery.
Chin can be shortened at LATER time too. BUT it is FINE where it is NOW and will be FINE after this particular proposed surgery. So, the surgeon is CORRECT not to change chin during this surgery which gives you OPTION to 'wait and see' at a LATER time whether or not you want to shorten it.
I AGREE with which ever surgeon gave you THIS plan and advised you NOT to get CHEEK IMPLANTS and chin shortening during the same surgery. But I do agree he could enhance cheek/upper midface area with HA paste/bone paste during same surgery which would help address any RELATIVE recession you might see to upper midface after your lower midface is displaced 'forward'.
