Recessed Chin - How Do We Measure?
It's important to define your terms. By "chin", do you mean the pogonion, or do you mean the mandible in general? Either way, both those things don't recess. The only thing that recesses really is the maxilla, and the mandible swings down to compensate. The best way to measure the effect on the mandible would probably just be the gonial angle. A high angle will make the mandible appear much weaker than if it was projected at a more right angle.
As you undergo correction in the near future, please consider keeping records for your own sake and for others. Pictures of dental impressions, scans, medical reports reports can be very helpful even with all personally identifying information blocked out.
