It's impossible to say for sure with only a photograph, but I would guess that the majority of the black tissue will not survive. However, you should be able to get a good long term outcome all the same, although it may require some additional surgeries. If you don't already have it, you need to arrange for follow up in the near future with an appropriately certified (facial) plastic surgeon to examine you create a plan for long term reconstruction.
Unfortunately this portion of tissue is unlikely to live. You will likely need multiple reconstructive procedure to repair this area. If the injury was something you did to yourself, please seek help immediately. Good luck, Michael Kim, MD
