I have a tendency unfortunately of sleeping on my face. Can the pressure affect the fat, and if so, would it only affect it for a short time proceeding the fat transfer procedure or could it potentially affect it indefinitely? I just had my second full round of FT post-rhinoplasty and I hadn't thought of this before, but I figured it might be relevant to the end result.
Does Sleeping on One's Face/side Potentially Affect Fat Transfer Retention?

Fat grafting and sleeping patterns
It certainly is possible that you could acutely move any transplanted material to the face if enough pressure is applied long enough. However, I think that after a few days or so it should not make much of a difference. There is also some evidence that continually lying on one side of the face can make it more wrinkled or sag more than the other side as well probably also a pressure related effect.
