I had the BSSO + LF1 if that's what you mean, yeah.
Ah, okay I'll just add a snippet of my movements then.
OK, that tells me your ANS moved UP (1.9mm) in the vertical direction and your PNS moved DOWN (3.7) in vertical direction for the CCW aspect of it. Can you confirm if you had anterior impaction AND posterior downgraft ?
Also, was this 'single' lefort 1 or was it SEGMENTED? For example IF he had to cut the lefort into 3 pieces to move around the upper front teeth separately from the 2 adjoining upper sides (multi-segment Lefort 1), although I can't go through all the scenarios where they might do that, one of them is to give more WIDTH so that the back upper teeth occlude well with the back upper teeth to the mandible like when there is some narrowness to the transverse maxilla.
Short and sweet, no matter what the multi segment lefort 1 was for, that is IF you got one, it would tend to putting a 'stretch' near the nasal base. Also, since L1 brings the nasal base FORWARD, it's going to look wider to you because it's MORE in the foreground.
So, let's say you did NOT get a multi segment L1 and just 2.6mm horizontal advancement of ANS with 1.9mm impaction to anterior maxilla. That's enough for your nasal base to LOOK wider to you whether you look at in the mirror or take a photo of it. It's because the 'forward' advancement (and yes, even with CCW) brings the nasal base forward and puts it more in the foreground even though it might not be 'technically' wider.
However, IF you did get a multi-segment L1 which usually increases the transverse direction (width between the right and left side of the upper back teeth), that's something that veers toward a STRETCH to the nasal base to make it 'absolutely' or 'technically' wider.
I know someone who went to Gunson who got LESS nasal base advancement than you (but MORE CCW via posterior downgraft) than you BUT he also got the multi-segment L1 to increase the transverse width so the side teeth would meet better with about the 14 mm advancement of the B point he got and he got the very WIDE nasal base with BOTH. Although Gunson didn't prepare him for that, I DID so he knew what to expect. But he was OK with it and I think people can be OK with something like that when they know what the trade-offs can be ahead of time.
