Appearance of dent on outer side of right eye after, Face lift plus upper & lower eye surgery, less than a year ago. (photo)

This is the result of a mid face dissection that was part of your surgical procedures.  The dissection plane used by the surgeon to enter the midface is a plane that contains a small amount of fat.  Unfortunately, the dissection itself can damage the fat which is later reabsorbed by the body as you heal from surgery.  This crease a depression in the temple area that outlines the zygomatic arch.  I call the deformity plateau midface because the effect is the appearance of a shelf or flat spot above the zygomatic arch.  Unfortunately this tiny bit of fat also services a critical aesthetic role in the face:  It isolated the eye aesthetic area from the temple.  The brake down and loss of fat here profoundly affects the gaze contact that other have of you during conversation.  Normally the person you are speaking do looks at your eyes most of the time but also gazes at the mouth and a little less at the nose.  This effectively sets of a triangular gaze pattern that we associate with someone actively interested in conversation.  When this little bit of fat is broken down, this gaze barrier is lost.  During conversation, the person speaking without no longer follows the gaze pattern we associate with interest.  Instead their gaze is distracted into the temple area and off the face.  Individuals with plateau midface often report that they feel that people are no longer paying attention to them.  

it appears that you have follow up volume changes from fat loss after surgical dissection. I have seen this scenario frequently and have had great success treating similar cases with injectable fillers. Best of luck

This is due to fat atrophy near the area of your eyelid surgery.  It is not common but can happen.  I would recommend fat grafting or fillers to correct this.  Communicate with your surgeon.  Good luck and be safe.John T. Nguyen, MD, FACS, FICSDouble Board Certified Plastic Surgeon
