18 days post lower face and neck lift, bleeding behind left ear. Do I need a graph or another suture or some special wound care?

Thank you for your question. Bleeding after 18 days is not usual, and it sounds as if there is an area behind your ear which is being chronically irritated and not allowed to completely heal. If there is an infection then it is best to let the area drain as opposed to closing it with more sutures. It will most likely heal on its own but you should see the treating physician to have the area examined. I hope this helps!

The source of the bleeding is obviously a surgical wound on that side.  Bleeding 18 days after the procedure is uncommon, however it is not necessarily cause for great concern.  It could simply represent some mild separation of the incision behind the ear or some minor skin necrosis.  Most of the time this situation is managed with wound care consisting of daily cleansing and application of petroleum based ointment.  It could also represent an extruding internal suture.  Additional stitching and skin grafts are typically not necessary at this point in healing.continue to follow up with your surgeon and follow his/her recommendations.

If you  had a small blood accumulation, the timing of blood being dissolved and absorbed by your body coincides with your story. If it is not causing distortion of the result, letting it drain like your surgeon advises is perfectly fine. Keep him/her advised of  any changes.
