What are the signs of compromised blood flow? (photo)

If there is any concern you should see your surgeon right away. It is really not possible to definitively distinguish bruising from decreased blood flow in a photograph. If your surgeon determines that poor blood flow is the cause, there may be some measures that can be taken (such as releasing sutures, foregoing ice packs and adding warmth, for example) that may possibly be of benefit. If it is bruising you may have a little bit of excess bleeding that he or she may wish to monitor. But the best course of action is to communicate your concerns and be seen by your surgeon. Good luck!

Looking at the photo you posted, I would have some concern for the skin in front of the ear following a facelift.  It could just be really bad bruising but it could also be early necrosis of the skin.  If you have not already, I would contact your surgeon to be evaluated.  An exam gives more information than a picture.  

Thanks for your picture. You should have your face evaluated by your surgeon. You have not given a lot of information about your surgery, but if you were my patient, I would want to see you in person.
