Hello flightlessbird,
I haven't had Type 3 (mine is scheduled May 2018) but I am not expecting to see positive results for several months after surgery. The surgeon who will be performing mine
provided CT scans - we drew on them in his office at my evaluation meeting, and after surgery I'll have a set of before/after CT scans. But even without these I'd be fully confident any reputable FFS surgeon will have performed the surgery they have billed for.
I had a much simpler facial soft-tissue procedure in November 2016 - upper blepharoplasty (eyelids). Swelling for the first several weeks prevented me from accurately seeing or even understanding the result, and at the one month mark I started to panic as I wondered if the crease in my eyelids was set in the wrong place. At six weeks my eyelids suddenly settled into the correct post-surgical shape and I calmed down. At 3 months I was very happy with the result and the final shape wasn't there until 6 months after surgery. And that's just for eyelids.
That's why doctors call us patients, they need us to be.
