You have a very distinct ANS but your Alfaro bone scan does not show the distintion. It almost looks like he cut off the point of your ANS in the BEFORE photo.
It looks like he is cutting a V shaped notch beneath your ANS so he can bring the rest of your maxilla forward WITHOUT giving you a deformity. It is a GOOD thing. But did he mention this to you?

Thanks a lot for the work here Kavan !
He did NOT mention this to me. I finished MSE expansion a month ago, so maybe that notch is the result of the MPS being split and healing ? And the lack of ANS in the before, a CBCT imaging mistake ? I noted your observation and if I can, I will ask him, for the sake of information, if he did plan this.
