What is skin grafting, its causes, types, and how to perform it


There is no doubt that having healthy and sound skin is one of the basic things that everyone seeks. However, some people may be exposed to accidents that lead to the loss of part of their skin for various reasons, which may cause them to feel a loss of self-confidence and psychological suffering. Therefore, skin grafting or skin transplantation is the ideal solution in these cases. In the following article, we will review in             Dalili Medical all the details related to this process, dear reader.

**How ​​long does it take for skin grafting to heal?**

 

The skin restoration process usually takes from 28 to 42 days in adults until complete healing occurs, as skin regeneration occurs during this period. It is worth noting that the speed of skin regeneration may be affected by several factors, such as age and general health condition.

**What to do if the skin grafting process fails?**

 

Skin grafting can fail for several reasons, such as infection or accumulation of blood and fluids under the transplanted skin. If this happens, the doctor may suggest re-performing the skin grafting process, or the wound can be bandaged regularly and left to heal naturally and slowly.

**When can you shower after a skin graft?**

 

It is recommended to avoid showering for two weeks after a skin graft. During the next two weeks, it is best not to expose the skin to water for more than five minutes. A mild soap can be used, rinsed well, and then gently dried with a soft towel.

**What is a skin graft?**

 

A skin graft is a surgical procedure that aims to improve the appearance of the skin by removing lines, scars, and burn marks.

How long does a skin graft take to heal?

 

The healing period varies from person to person and depends on the size of the damaged area and the location of the graft, but the process usually takes a few weeks to complete.

Can scars appear after a graft?

 

Slight scarring may appear after a graft, but with the patient following the necessary wound care procedures, the appearance of these scars can fade over time.

Are grafts suitable for everyone?

 

Skin grafts are usually suitable for most skin problems, but there are some exceptional cases that should be taken into consideration. It is preferable to consult a specialist doctor to determine whether this technique is appropriate for the patient's specific condition.

When is skin grafting necessary?

 

As with many surgical procedures, skin grafting is resorted to for specific reasons, where the doctor decides to perform skin grafting in the following cases:

• Exposure to severe and deep burns.

• The presence of cracks or open wounds.

• Skin injuries resulting from certain diseases, such as ulcers or infections that did not heal well.

• Skin cancer, which requires surgery to remove the tumor.

What should you know before skin grafting surgery?

 

If you are taking certain medications, such as aspirin, you should inform your doctor, as these medications can interact with blood components and cause problems, such as clots. The doctor usually asks you to stop taking these medications or adjust the dose before surgery.

It is also recommended to stop smoking, as it reduces the chances of recovery.

Your doctor may also ask you to fast from food and drink starting at midnight, to avoid sudden complications during surgery, such as vomiting or suffocation.

What is the difference between a skin graft and a flap?

 

A skin graft is very similar to a skin graft, but during flap surgery, fat and muscle are also transplanted, and healthy skin is surgically connected to blood vessels, ensuring that the flap has its own blood flow. This technique helps speed up the healing process and minimize scarring.

Where do doctors get the skin used for grafting?

 

Doctors usually use healthy skin taken from the patient’s own body, a process known as an “autograft.” In some cases, the patient may not have enough healthy skin to perform this type of graft, in which case the doctor may have to take skin from a cadaver, known as an “allograft.” Animal skin can also be used, called a “xenograft.” This type of graft is usually temporary, as it aims to cover the damaged skin until the wound heals or the person grows enough healthy skin to use in the permanent graft.

**Types of Skin Grafts**

There are three main types of skin grafts, as follows:

**Skin grafting (STSG)**In this procedure, the doctor takes a graft from the top layer of skin (epidermis) along with a portion of the second layer (dermis). This type is usually used to cover large areas of damaged or missing skin. The healthy skin is often taken from the thigh, lower abdomen, or back, and the area from which the skin was taken heals naturally within one to two weeks.

**Full-thickness skin graft (FTSG)**In this type, the doctor takes a graft from both the top and bottom layers of the skin to transplant. Healing takes longer than with partial-thickness skin grafts because the transplanted skin is thicker. Doctors prefer to use full-thickness skin grafts in areas that are not normally covered by clothing, such as the face. The healthy skin is taken from the thigh, arm, or collarbone, and the wound in the donor area is closed immediately.

***Composite Grafts**During this procedure, doctors graft skin with cartilage or other soft tissue. Composite grafts help repair damage to the nose, fingertips, and ears.

**Skin Grafts After Burns for Children**

 

Children who have suffered severe burns need special care due to their sensitive skin and constant growth. Skin grafts after burns are necessary not only for cosmetic reasons, but also to improve skin function and prevent complications such as skin contractures or growth abnormalities.

**Deep Injuries and Wounds:**Skin grafts are usedSkin grafting is also used in cases of accidents, such as traffic accidents or wounds caused by sharp instruments, as these injuries lead to the loss of parts of the skin, which requires grafting to restore skin functions and avoid complications.

Skin grafting is also resorted to after major surgeries, such as removing tumors or repairing damaged tissues.

.** Skin ulcers and deformities**:

- **Chronic skin ulcers**: such as pressure ulcers or ulcers resulting from diabetes, as these conditions lead to skin erosion and the appearance of open wounds that require grafting.

- **Congenital or pathological deformities**: Some skin diseases or congenital conditions may lead to deformities or loss of skin, which requires grafting to improve the appearance and functions of the skin.

.** After tumor removal**:

- **Skin tumor removal**: After removing large tumors, the operation may result in the loss of a large part of the skin, which requires grafting to rebuild the damaged area.

**Sports or military injuries**:

War or sports injuries can result in the loss of parts of the skin due to deep wounds or injuries caused by explosives or weapons, which requires skin grafting.

**Chronic skin diseases**:

These include diseases such as chronic eczema or psoriasis, which cause extensive damage to the skin and may require the use of skin grafts in severe cases.

**Timing of skin grafting**:

The timing of the procedure is determined by the patient’s condition and the severity of the injury. In cases of severe burns or injuries, skin grafting is performed after the patient’s condition has stabilized sufficiently, and before any complications such as infection appear. Sometimes, the procedure may be delayed to ensure that the affected area is ready to receive the transplanted skin, which contributes to the success of the procedure.

What are the risks associated with skin grafting?

 

Risks of anesthesia include:

- Allergic reactions to medications

- Breathing problems

- Bleeding, blood clots, or infection

Surgical risks include:

- Chronic pain (rare)

- Bleeding

- Infection

- Loss of grafted skin (grafts not healing or healing slowly)

- Decreased or lost sensation in the skin or increased sensitivity

- Scarring

- Uneven skin surface

- Skin discoloration

**Methods for treating the effects of grafting operations**

 

There are various methods for treating the effects of grafting operations, the most prominent of which are:

**Using cosmetics** There are cosmetics designed to cover and hide the effects of skin resulting from some skin diseases or surgical operations. These preparations are often considered an effective means of treating the effects of grafting operations, especially in the face area.

**Laser Treatment** Lasers are used in several techniques to treat the effects of grafting operations, as this treatment aims to improve the appearance of scars or remove skin pigmentation associated with them. Types of laser treatment include the following:

. **Vascular Laser** Vascular laser works to shrink the blood vessels that feed the affected areas of the skin, which helps reduce the appearance of red discolorations. It is important to note that this treatment is done without the need for drugs.

. **Skin Resurfacing Laser** Two types of lasers are used in the skin resurfacing process, which are carbon dioxide laser and erbium laser. Carbon dioxide laser is used to treat deep scars, while erbium laser is preferred for superficial scars, especially in people with dark skin.

**Silicone** Silicone is one of the effective ways to treat the effects of grafting operations, especially hypertrophic scars or keloid scars. Silicone sheets or gel are used to reduce these scars.

Silicone sheets or gel are applied to the scars for 12 hours a day, for at least 3 months.

It is worth noting that silicone may help relieve the itching associated with scars, but should be avoided on open wounds.

**Steroids** Steroids are used to treat keloid and hypertrophic scars, either by applying them topically directly to the scars or by injection.

Steroids help reduce the size of scars and relieve the redness, itching and burning associated with them.

The injection process is done by inserting steroids under the skin in three sessions, with a period of 4 to 6 weeks between each session. Treatment can continue for several months if an improvement in the condition of the scars is noticed.

As for topical treatment, it is done using steroid strips that are applied to the affected area for 12 hours a day.

**Cryotherapy** Cryotherapy includes treating the effects of grafting operations by freezing the keloid scars using liquid nitrogen. This treatment can help reduce the size of scars and prevent them from expanding, especially if used in the early stages of scar formation. Cryotherapy is more effective when combined with steroid injections to treat the effects of grafting operations.

**Fillers** Fillers such as collagen and others can be used to treat some sunken scars resulting from grafting operations. However, this method is often expensive and not permanent, as it requires repeating the process several times to maintain the results.

**Skin puncture** Skin puncture treatment involves using a device equipped with small needles that are rolled over the surface of the skin repeatedly, which helps improve the appearance of the skin.

**Pressure therapy** Pressure therapy is used to treat large keloid scars that may appear after grafting operations, by wearing elastic bandages on the scar area around the clock for a period ranging from 4 to 6 months.

Silicone sheets or gel can also be used with pressure therapy to improve the appearance of scars in the long term.

**Surgery**If the above treatments do not improve the effects of the grafting operations, surgery is resorted to, which involves removing the scars or scraping the skin.

Surgery aims to make the scars appear more naturalIt can also help reduce or eliminate scarring at the joints to facilitate movement.

**Radiation Therapy**Radiation therapy can be used as a complementary procedure to surgery to reduce the likelihood of keloid scars reappearing in the future.

**How ​​to care for after skin grafting**

 

Skin grafting usually requires care for two sites: the donor site and the graft site. The doctor will monitor for signs of infection to ensure proper healing at both sites. After surgery, the patient may need to stay in the hospital for up to two weeks, depending on the type of surgery performed. It is important to follow the doctor's instructions even after returning home, which may include:

- **Wound Coverage:** You should consult your doctor about how long the bandage should remain, whether it can be wet, and how often it should be changed. The doctor may recommend using aloe vera cream or an antibiotic cream.

- **Wound Protection:** Avoid physical activities that may negatively affect the graft during the healing period, and avoid strenuous exercise for three to four weeks.

- **Taking pain relief medications:** Your doctor may prescribe some painkillers to relieve pain after the operation, in addition to other medications to help reduce inflammation or prevent infection.

- **Follow-up visits:** It is essential for your doctor to examine your skin and monitor the healing process to ensure proper recovery. He may also recommend a physical therapy program to improve skin elasticity and prevent tissue buildup.

**Cleaning the wound:** It is preferable to clean the wound gently with warm water and soap. Make sure to dry the wound well without moving the graft.

**Applying anti-inflammatory substances:** It is recommended to apply an anti-inflammatory ointment to the wound regularly, according to your doctor’s instructions.

**Protecting the skin from the sun:** The graft should be covered with a bandage or wearing clothes that protect the skin from direct exposure to sunlight.

**Avoid stress and injuries:** It is preferable to avoid any strenuous activity that may increase pressure or affect the graft, such as intense exercise or weight lifting.

**Maintaining good nutrition and digestion:** It is recommended to eat a healthy, balanced diet and drink enough water to support the skin healing process.

**Do not peel or scratch the patched skin:** You should avoid scratching the patched skin or trying to remove it manually, as this may damage the patch and delay the healing process.
