Thank you for your question. You need to see your Plastic Surgeon today for his recommendation of your wounds. If you are a smoker, you must discontinue all nicotine products. Best wishes on your healing and recovery.
Visit with your plastic surgeon as soon as you can . One wants to prevent that incision from opening further and your plastic surgeon will know best how to proceed. It should heal well if it stays this size. Best wishes.
Your repair has opened and I can see the subcutaneous fat in your picture. First thing would be to place triple antibiotic ointment and a dressing over the area and call your plastic surgeon right away!
The area may open further. A relatively simple repair under local can eventually be done in the office. The timing of this would be decided by your plastic surgeon.
