How does the surgeon know what the result will be if working on a patient laying down if marked when sitting up?

The marks are actually placed while you're sitting upright for this very reason. When you're laying flat during the surgery the markings tell me where the important landmarks are located. When you lay down, the neck relaxes, cheeks fall back and the jowls move. The markings tell your surgeon where all of that tissue is typically located. The ability to properly reposition these tissue improves with experience. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

This is an excellent question!The markings as well as experience best determine the outcome.This principle also applies to breast and body contouring.A board certified Plastic Surgeon with several years of experience is your best option for having a result to meet your expectations.Good Luck!
