How it works
Everything begins with an examination and a conversation. The doctors will look at the wound directly, assess its depth, whether infection is present, and the structures that lie beneath. You will be asked about your medical history, the medicines you take, and your daily habits. From there, your doctor talks with you about the coverage options that suit you and what is reasonable to expect.
Before coverage, the wound usually needs to be prepared. The doctor may perform debridement, which means removing dead and infected tissue to reveal a clean wound bed with a good blood supply. This step sometimes happens in the same session, and sometimes it needs one or more separate sessions before coverage goes ahead.
The coverage is done in the operating room. Depending on the extent, you may have local anesthesia, regional anesthesia, or general anesthesia. The doctor chooses the coverage method based on location and depth: a skin graft, where a thin layer of skin is taken from another part of your body and laid over the area; or a flap, where a block of tissue that keeps its own blood supply is moved to cover the wound when a thicker cushion is needed or when tendon or bone is exposed. Your doctor will go over the specific method clearly with you before surgery.
After coverage, the operated area and the donor site (if there is one) are dressed and watched closely. The goal of the first few days is to keep the covering tissue well supplied with blood, free of infection, and adhering well to the bed beneath it.
