I had FFS the day after I legally changed my name and went full time into transition.
I had a few consultants with surgeons 6 months before that time to get their perceptions (and give them mine) of what I needed / wanted, which was not to far apart from my expectations.
I left work on a Friday and had FFS on the Monday, which included, Brow bossing and forehead reconstruction, Open Revision Septorhinoplasty, Jaw shaving and angle of mandible reduction, Tracheal shave, Bilateral Otoplasty and upper and lower bletheroplasty.
I had a second round of facial surgery last year which included Face lift, necklift and scalp advance, before having hair transplants in March this year.
The surgeries where 5 years apart, why?.... It just worked out like that.
If you are having FFS, I would do as much as the surgeon is reasonably comfortable with in one go, my first FFS was 9 hours long.
