What is Skin-Muscle Grafting: Overview, Benefits, and Expected Results
Skin-muscle grafting is a reconstructive procedure used to repair tissue damage caused by trauma, burns, or the removal of large tissue masses. During the procedure, grafted material is transferred from one area of the body to another, sometimes creating a new muscle or restoring existing muscle function, depending on the extent of the treatment required. In this article, we will take a look at what is involved in the process of skin-muscle grafting, as well as the potential benefits and expected results of the procedure.
What is Skin-Muscle Grafting?
Skin-muscle grafting is a reconstructive surgery that involves the transfer of skin and muscle tissue from one area of the body to another. During the procedure, a piece of skin and muscle is taken from the donor site, typically from the thigh or lower abdomen, and transferred to the recipient site. The donor site is then surgically closed and the recipient site is repaired with sutures.
The skin and muscle tissue, along with any accompanying fat, are then connected and sutured together in order to create a new muscle or to restore the existing muscle function. In some cases, a graft of skin alone is transferred from one area of the body to another in order to provide skin coverage over a wound.
Skin-muscle grafts are often used to reconstruct areas of the body that have been damaged due to trauma, burns, or tumor removal. The procedure can also be used to repair defects in soft tissue that are the result of congenital abnormalities or surgical procedures.
Steps Involved in the Skin-Muscle Graft Procedure
The skin-muscle graft procedure typically involves the following steps:
- Incision – A small incision is made at the donor and recipient site and the skin and muscle tissue is identified.
- Harvesting – The tissue is then carefully removed from the donor site and placed in a sterile container.
- Processing – If needed, the tissue is further processed and prepared for grafting.
- Grafting – The graft is then carefully placed and secured in the recipient area and any excess tissue is trimmed as needed.
- Suturing – The graft is then sutured, both at the recipient site and the donor site, in order to secure it in place.
- Monitoring – The patient is then monitored for any signs of infection or other complications.
Benefits of Skin-Muscle Grafting
Skin-Muscle Grafting offers a number of benefits, including:
- Improved Function – Skin-muscle grafts can help to restore or improve muscle function that has been lost due to trauma, burn, or tumor removal.
- Reduced Scarring – In some cases, skin-muscle grafts can help to reduce scarring and improve the appearance of the area.
- Promotes Healing – Skin-muscle grafts help to promote healing and can reduce the risk of infection.
- Minimally Invasive – Skin-muscle grafts are generally minimally invasive, meaning that recovery time is reduced when compared to other surgical procedures.
Expected Results of Skin-Muscle Grafts
The outcome of skin-muscle grafting will depend on the type and extent of the procedure, as well as the overall health of the patient, but typically patients can expect the following:
- Reduced Scarring – With skin-muscle grafts, patients can expect to have reduced scarring in the recipient area due to the use of healthy tissue from the donor site.
- Improved Function – Skin-muscle grafts can help to improve or restore existing muscle function in the recipient area.
- Better Appearance – In some cases, patients may see an improved or more aesthetically pleasing appearance in the recipient area due to the use of healthy tissue from the donor site.
- Reduced Risk of Infection – Skin-muscle grafts can help to reduce the risk of infection due to the use of healthy tissue from the donor site.
Possible Complications of Skin-Muscle Grafts
While skin-muscle grafts are generally safe, there is always a risk for complications, such as:
- Infection – There is a risk of infection in the graft site that can lead to further complications.
- Nerve Damage – There is a risk of nerve damage in the graft site that can lead to loss of sensation in the area.
- Graft Rejection – The body may also reject the graft, leading to a failure of the grafting procedure.
- Scarring – There is a risk of scarring due to the incisions made in the donor and recipient sites.

التعريف والنظرة العامة
Skin-muscle grafting is a procedure in which healthy skin and muscle are taken from one part of the body (donor site) and transplanted onto the recipient site to replace damaged or missing skin. The transplanted skin and muscle are called a skin-muscle graft. This procedure is used to treat patients who suffer from severely damaged skin and muscle.
In some cases, grafting of skin is also performed using an allograft, or donor skin taken from frozen or stored cadavers, or a xenograft, donor skin taken from an animal. A xenograft serves as a temporary covering as the patient’s body rejects it after a few days. It is often replaced with an autograft, or donor skin taken from the patient’s own body.

Patients who should undergo skin-muscle grafting are those whose skin and muscle are severely damaged due to:
Skin and muscle trauma
Skin loss due to certain diseases, such as:
Ulcers that do not heal, including:
Serious skin wounds can put a patient’s health and well-being at risk. Large, exposed wounds that do not heal properly are highly susceptible to bacterial and virus infections. Thus, they need to be covered with a skin-muscle graft, which can also help regulate the temperature of the skin and prevent fluid loss in burn patients.
Moreover, by removing and replacing the damaged skin and muscle, a skin-muscle grafting procedure reduces the number of treatments as well as shortens the patient’s recovery time and hospital stay. As an added benefit, the skin and muscle transplant can also improve the appearance as well as the function of the affected body part.
In order to ensure a pleasant appearance, skin-muscle grafts are taken from carefully chosen donor areas. The donor body part should:
Match the colour of the recipient site
Not be visible or can be hidden by clothing
Be close enough to the recipient site
كيف يتم إجراء العملية؟
The process of skin grafting involves the removal of the damaged skin and muscle. Once the damaged skin and muscle are removed, they are replaced with a skin and muscle graft.
Skin grafts come in two types:
Full thickness skin graft – A full thickness graft cuts the skin from the donor site including the fat and muscle. This type of skin grafting procedure is riskier and may leave a scar, but it is sometimes the only option for some patients, especially those whose injuries are quite severe. Despite the risks involved, a full-thickness graft provides some advantages, such as a more natural colour, better skin contour, and less skin contracted once transplanted onto the donor site.
Partial or split thickness skin graft – A partial thickness skin graft refers to a thin layer of skin removed from the donor site. This graft includes the epidermis and a little of the dermis underneath it. A split thickness skin graft is harvested using special skin grafting instruments. Since the skin taken from the site is very thin, the donor site heals very fast. However, this type of skin graft is not sufficient for large, extensive skin and muscle injuries.
The success of a skin grafting process depends heavily on how the skin-muscle graft is taken and handled, as well as how the donor site/wound is prepared. This is because healthy skin and muscle grafts will not survive on donor sites with poor blood supply or damaged skin tissues. It is important for doctors to make sure that the donor site is not contaminated by dead tissue, bacteria, and viruses, as well as any kind of foreign matter. This can be achieved by rinsing the wound with saline solution or diluted antiseptic. Dead tissues must also be removed through a procedure called debridement.
Once the wound is prepared, the surgeon ties off the blood vessels connected to the wound area to temporarily stop the flow of blood. The patient may also be given epinephrine to constrict the blood vessels. Once the donor site is ready, the skin and muscle graft is harvested and transplanted onto the donor site and held in place with absorbable sutures.
Skin grafting cost depends on the type of skin-muscle graft used as well as the size and severity of the patient’s wounds.
المخاطر والمضاعفات المحتملة
A skin-muscle grafting procedure comes with certain risks because the patient has to care for two wounds (graft and donor sites). Both wounds are covered with a dressing for protection following the procedure. The dressing also helps absorb fluids that may leak from the wound.
Potential complications of skin grafting include:
Skin-muscle graft rejection
Pain in the donor site
To prevent serious complications, patients need to rest for several days after a skin-muscle grafting procedure. The wound dressings should be changed regularly and kept in place for as long as the doctor recommends. To minimise swelling, the wounds should be kept at a level higher than the heart. Strenuous activities should also be avoided until both wounds are fully healed.
As part of after skin grafting care, patients should also watch out for signs of an infected wound, such as:
Pain that is not relieved by pain medications
نزيف that does not stop after 10 minutes even when pressure is applied
Bulging of the graft site
Increased wound drainage
Thick, green, and smelly drainage from the wound
Red streaks leading away from the wound
Patients should also check if the edges of the graft are secured. To prevent the graft from loosening, it has to be supported with a bandage or compression stockings for months. Also, since the skin muscle-graft does not contain oil and sweat glands, the graft site should be lubricated with mineral oils for three months following the surgery.
Patients who suffer from severe skin damage that has affected their appearance may also need psychological rehabilitation. This is often true in cases of grafting skin for burns patients.
