Basically this is how it is probably going to go. You will have to fill out some forms, then get the CT scan, then sit a while and have coffee and get photos taken - several sets for documentation, 3D imaging and VFFS - then you get the consultation. The surgeons usually will have printouts of the CT and photos and will want to also touch your face to feel the things they see on the scan.
Then it depends - if you go there for the first time, they can go on and tell you what features are most masculine, which should be adressed, what to do about it and they can draw lines on the CT scan to show what they would change. If Alexandra is there, she also will do a live photo simulation of the things discussed so you can see the outcome.
If you have any specific questions, you should not them and probably will either have to intterrupt the assessment, or better wait until the assessment is ending and they ask you what you want to know. But overall it can be a dialogue.
So the standard questions will be answered anyways, its up to you to ask specific questions that you have in mind - like if you have some part of the face that worries you most or that you have a specific image how it should me in your head - you can discuss this. In my opinion, Alexandra is rather reluctant to consider personal beauty choices, but the team is not, they will even accept if you want some masculine features because it is a family trait and not try to talk you out of it. They do have some limits though where they will not go - they do not take away as much bone as some other surgeons may accept to do, for medical reasons.
So genreally - they will be doing a "presentation" and guide you through the consultation if you do not ask, which is fine, but if you want to know some specific things or individual questions, write them down and either ask them when they talk about the area in question or ask them at the end of the process. If you already know some things about FFS you can tell them , so they save time explaining how a FFS is done and what a FFS is.
