Incision open 4 weeks post tummy tuck. What do I do about it? Will it keep spreading? (Photo)

Thanks for your question and photo.  Sorry to hear you are having a complication.  These small areas of slow healing after a tummy tuck are not uncommon.  From what I can see in the photo it looks small and clean. Best to call your Dr.'s office and talk to whomever is covering for them.  In the meantime, it is reasonable to put steri-strips over it or cover with a bandaid and some bacitracin antibiotic ointment (assuming you are not allergic to it).  Good luck.  

Sorry to hear about the complication you have experienced. These types of superficial separations or wounds can occur, and sometimes may “look worse, before it looks better”. In my opinion, the most important “factor” involved with successful treatment of the complication will be close follow-up with your plastic surgeon. He/she will be in the best position to monitor situation carefully. Infections should be ruled out and “foreign bodies” such as sutures that may prevent quick healing may be removed. The open wound should go on to heal over the course of the next several weeks, hopefully without long-term sequelae. Concentrate on a well-balanced ( good protein source) diet. Best wishes.

Looks like a small area of marginal skin necrosis. This will heal if you keep ointment on it and protect with a bandage. As long as it is not infected (fever, redness, tender), then it can wait until your plastic surgeon is back, if infected you need to see a doctor ASAP.
