Can frequent head and neck movement after surgery compromise Mid Facelift?

This is a good question. It is inevitable that someone is going to move their head in various directions after facelift surgery. This is natural and shouldn't impact your results, unless you are making aggressive movements (ie. fast and/or extensive stretches). Naturally your face and neck will feel tight for several weeks to several months after this procedure, but its because of these unconscious natural daily movements we make that slowly stretches things out to a more natural and less tense state - and this is good, as long as you are not over-extending yourself. In summary, you should be fine, especially since you are several weeks out from surgery. Hope this helps!

Facial movement after a face will not have an effect on your facelift results. Depending on your age and physical exam the some neck laxity can return in a very limited way over time.

I don’t think head and neck range of motion is going to have any impact on the outcome of a midface lift.
The movements you describe have nothing to do with your midface.
All of that range of motion is in your neck and you didn’t have neck surgery.
Plastic surgical outcomes are primarily determined by patient, candidacy, and provider selection.
There is very little that postoperative care or activity is going to do to change the outcome of most plastic surgical procedures.
The outcome of the operation is usually determined when the surgeon finishes the operation.
