Debridement can be performed either surgically or nonsurgically; some methods are less invasive than others. Doctors select the appropriate debridement technique by considering the location, cause, and size of a patient's wound and may also weigh the patient's overall wellbeing, age, and risk of infection.

Surgical debridement is performed by cutting away dead, infected, and hyperkeratotic skin with a surgical scalpel. For deep wounds that tear away the skin and go into the muscle, skin from another region of a patient's body may be grafted onto the wound, which may then be periodically assessed and rebandaged until fully healed.

Non-surgical debridement is achieved with water or a dissolvent gel. Water softens the damaged skin and affected tissue, allowing doctors to remove it with wet-to-dry dressing. When wet tissue dries, it adheres to the dry dressing or bandage and comes off when the dressing is pulled away. In contrast, dissolvent gel deconstructs tissue, which can be cleaned off of the wound. Nonsurgical debridement is less invasive than surgical techniques; however, it can entail repeat treatments, slowing wound recovery.

While the prospect of stripping away skin may seem jarring, debridement can be critical to the treatment and healing of wounds which cannot not heal independently.

In all cases, the skin graft may either be full-thickness or partial-thickness. While thicker grafts make recovery more difficult for the donor site, they heal more easily than thinner grafts.

Before skin graft surgery, patients are given anesthesia so they cannot feel any pain. If using an autograft, the surgeon carefully measures and removes the skin from the donor site. Sometimes the graft is cut in a mesh-like pattern, to allow a small piece of donated skin to stretch and cover a larger area. This also helps oxygen pass through the graft. The site where the skin graft will go is cleaned well to remove any dirt, bacteria, or dead skin cells. Then the skin graft is placed and attached with stitches or staples. It is often covered with antibacterial ointment and supportive bandages for the first few days.

As the skin graft heals into its new position, new blood vessels grow to reach and support the skin. Depending on the thickness of the graft, oil glands, sweat glands, and hair follicles may also regrow. Recovery time depends on the thickness of the graft and the overall health of the skin in the grafted area, but it generally takes from two to four weeks.
