I previously used simulation software for every facial rejuvenation procedure on every patient, including facelifts, eyelid surgery, chin augmentation, brow lifts, etc. In most cases, I use simulations only for rhinoplasty now. I find that facial rejuvenation patients can get just as much of an idea about their predicted surgical results by looking at before and after images of my patients on my website, social media, etc. Computer simulations sometimes look unrealistic (not always with respect to the amount of improvement, but simply the appearance of the skin, shape of the tissues, etc), and don't really add much value to the patient. I do perform facelift simulations if a patient requests them.All the best,
