What you need to know about a skin graft

Have you ever had a big burn, a bad wound from an accident, or a skin cancer that left a scar? This is when doctors talk about a "skin graft." Some people may feel a little scared when they hear the word. But it's actually a very successful surgery that makes a big difference in the lives of many people. So today, let's find answers to all your questions about skin grafts, as simple as talking to a friend.

What is a skin graft, simply put?

Simply put, a skin graft is a surgical procedure that involves taking healthy skin from one part of your body and grafting it onto a damaged or missing part of your body. It’s like transplanting a plant to another part of your body. Within a few days, the newly grafted skin will begin to develop blood vessels and connect to the surrounding tissue.

Doctors use this method to help people who have damaged skin due to burns, accidents, skin diseases, or infections. It is also sometimes used to fill the gap left after removing skin cancer.

The recovery time after this surgery will vary depending on your general health, the amount of skin grafted, and the type of surgery performed. Most of the time, this surgery is successful the first time. However, very rarely, if the grafted skin does not adhere properly, another surgery may be necessary.

Where do you get skin for grafting?

Most of the time, doctors take skin from a healthy part of the patient's own body . This is called an ``Autograft''. This is the safest and most successful method.

But sometimes, especially if someone has suffered a large area of ​​burns, there may not be enough healthy skin left to take from their own body. In such cases, other methods are used:

• Allograft: Temporary transplantation of skin from a deceased person (cadaver).
• Xenograft: The temporary transplantation of skin from an animal, usually a pig.

What are the main methods of skin grafting?

There are three main methods of skin grafting. Your doctor will choose the most appropriate method based on the nature, location, and size of your wound.

In what cases is a skin graft necessary?

Your doctor may recommend this surgery if you have skin that is too damaged or missing to heal on its own. Here are some examples:

• Burns: Severe burns.
• Infections: Severe infections that damage the skin.
• Skin cancer surgery: To fill the gap left after the cancer is removed (e.g. Mohs surgery).
• Ulcers and Bedsores: Non-healing wounds.
• Very large wounds: Wounds that are too large to heal on their own.

What happens before and during surgery?

Preparation before surgery

Before surgery, your doctor may ask you to stop taking certain medications, such as blood thinners. If you smoke, you should definitely stop smoking a few weeks before surgery. This is because smokers have a slower healing process, which increases the risk of surgery failing.

Before the surgery, the doctor will examine you and determine the donor site and graft site. When choosing a skin graft site, the doctor will try to choose a site that is similar in color and texture to the skin of the graft site.

During surgery

This surgery is done in a hospital. You are usually given general anesthesia. However, if it is a small transplant, you may be given local anesthesia.

The surgeon cuts and takes skin from a healthy area (e.g., thigh, abdomen, back) that has been determined. Then, before the skin is grafted, small holes or mesh-like incisions are made in it. This is called ``meshing''. This is done to stretch the skin over a larger area and to help the wound heal faster.

This skin is then glued to the damaged area, secured with stitches or staples, and covered tightly with a dressing.

What happens after surgery?

Since there are two wounds (the skin incision and the skin graft), the doctor will carefully monitor both to make sure they are healing properly and for any infections. Depending on the nature of the surgery, you may need to stay in the hospital for about two weeks. After you go home, you should follow your doctor's instructions exactly.

• Keeping the wound covered: Ask your doctor how long you should keep the bandage on, whether it should be wet, and when to change it. They may tell you to use an antibiotic cream.
• Protecting the wound: Avoid activities that stretch the skin in the area, such as heavy exercise, for 3-4 weeks until the wound heals.
• Taking painkillers: The doctor will prescribe medication for the pain that occurs after surgery. Use them correctly.
• Follow-up: Be sure to go to the doctor's appointments to check on the wounds. Sometimes, physical therapy (PT) may be recommended to increase the elasticity of the grafted skin and reduce the formation of scar tissue.

What are the risks and complications of this?

Most skin grafts are successful. However, sometimes the grafted skin may not adhere to the new site. There are several main reasons why this can happen:

• Blood or pus collecting under the grafted skin.
• Infection.
• Damage to the grafted area during healing (e.g., excessive shaking).
• Delayed wound healing due to circulatory problems (this is more common in smokers ).

In addition, bleeding, contracture of the grafted skin, skin discoloration, loss of sensation or hypersensitivity, and chronic pain may occur. However, these can often be managed by a skilled medical team.

When do you need to see the doctor urgently?

If you notice anything like this when you get home after surgery, you should call your doctor immediately :

• If blood or pus is oozing from the wound.
• If you have severe pain that cannot be controlled even with medication.
• If you are showing signs of infection, such as a fever .

If a skin graft is performed on a young child, the grafted skin may not grow back as the child grows. In such cases, another surgery may be needed in the future. Talk to your doctor about this as well.
