Skin grafting in outpatient procedures – how does it work?

Content author: MD. Piotr Rak, surgeon · Editorial work: Editorial team of Wyspa Medycyny Przyjaznej · Medical review:  Ph.D. Piotr Rak · Date of creation: 07.08.2026 · Date of review: 07.08.2026 · Updated: 07.08.2026

The article is of an educational nature and does not replace qualifications for the procedure, which requires examination. Increasing pain, fever, spreading redness, leakage of pus, heavy bleeding from under the dressing or soaking of the dressing with blood require urgent contact with a doctor. The dressing should not be removed on your own before the scheduled date.

The most important information at a glance

• Skin graft involves covering the defect with skin taken from another area of ​​the body of the same patient.
• It is used when direct suturing of the wound is impossible or would disfigure the area.
• The most common reason in outpatient settings is a defect after excision of a skin lesion on the face or hand.
• The graft does not have its own blood supply - in the first days it feeds from the substrate and only then grows into it.
• Therefore, immobilization and pressure dressing in the first days are crucial.
• The procedure is performed under local anesthesia; the patient goes home the same day.
• The donor site is selected so that the color and thickness of the skin match the recipient area.
• Tobacco smoking is the strongest factor worsening the acceptance of a transplant over which the patient has control.
• The transplanted skin usually differs slightly in shade and texture - the effect improves over many months.
• Not every defect requires a transplant; alternatives include direct suturing, a skin flap or healing by granulation.

Doctor. Piotr Rak is a surgeon at the Island of Friendly Medicine in Gdańsk. He deals with surgical procedures, including the removal of skin lesions and the dressing of defects. When planning such a procedure, the decision is made before the incision, not after it: the method of closing the wound must be planned already at the qualification stage.

What is a skin graft

A skin graft is a piece of skin taken from one part of the body and transferred to the defect site. The key feature that distinguishes it from other reconstruction methods: the graft is completely cut off from its blood supply. It has no vessels of its own to supply it with blood at the time of transfer.

This explains the entire course of action after the procedure - and that is why it is worth understanding how such a transplant survives.

In the first days it feeds passively, absorbing fluid from the wound base. This is the most critical period. Then, the vessels of the substrate and the graft begin to connect, and in the following days circulation is restored. Only then does the graft begin to function like its own, blood-supplied skin.

The practical consequence is one and the most important in this entire article: everything that separates the graft from the substrate prevents its survival. A hematoma, a shift, a movement, a pool of fluid - each of these things breaks contact with the ground. Therefore, pressure dressing and immobilization are not precautions, but a requirement for success.

Graft, flap or simple suturing - what's the difference?

Patients often use the word "graft" for any reconstruction. In practice, the surgeon chooses from several options, and the choice is made at the stage of planning the procedure.

The difference between a graft and a flap is essential. The lobe retains its own blood supply — is moved but remains connected to the tissue from which it comes. Therefore, it heals more reliably and usually produces a better color effect, but requires an adequate supply of skin in the vicinity. A transplant does not have such a connection and therefore its acceptance is never one hundred percent certain.

When is a transplant needed?

In outpatient practice, the most common reason is a defect resulting from the removal of a skin lesion - especially in areas where the skin is tight and there is no reserve of it.

• Nose — especially the wings and back, where the skin is thin and adheres to the cartilage.
• Earlobe — there is no spare skin, and stitching would distort the shape of the ear.
• Eye socket area — stretching the skin could turn the eyelid out.
• Forehead and temples — for larger losses.
• Backs of hands and fingers — taut, mobile skin, difficult to approach.
• Drumsticks — an area with poorer blood supply and more difficult healing.
• Wounds after injuries with skin loss.
• Chronic wounds, after appropriate preparation of the substrate.

It is worth emphasizing that the decision does not depend solely on the size of the defect. Equally important is what's next. The same defect on the back will be sutured without any problems, but on the wing of the nose it will require reconstruction - because stretching the skin would shift the edge of the nostril.

A separate situation concerns cancer. When skin cancer is suspected, the priority is complete excision with an adequate margin, and reconstruction is planned around this requirement, and not the other way around. Sometimes, reconstruction is postponed until a histopathological examination result confirms that the margins are free from infiltration.

Where is the skin taken from?

The donor site is selected according to three criteria: matching the color and thickness to the recipient area, the ability to hide the scar and the availability of skin with appropriate characteristics.

Color matching may be a surprise for patients. Skin taken from the groin and transferred to the face will remain visibly darker for a long time - which is why facial reconstructions focus on areas with similar characteristics, even if this means an additional incision elsewhere.

How the procedure is carried out

The entire procedure is performed under local anesthesia and usually lasts from several dozen minutes to about an hour, depending on the size of the defect and its location. The patient goes home the same day.

Stages four and eight determine success. Preparation of the substrate must ensure that the wound bottom is well supplied with blood and does not contain any remaining blood - the most common cause of failure is a hematoma, which mechanically moves the graft away from the substrate. Pressure dressing maintains tight contact during the first days when the graft does not yet have its own circulation.

After the procedure - what determines success

This is the most important part for the patient because in the case of transplant the result depends on the patient's behavior more than with most other skin procedures.

• Do not remove the dressing yourself. The date of the first change is set by the operator and it is not worth rushing it out of curiosity.
• Keep the dressing dry - washing and bathing rules are determined by the doctor.
• Limit movement of the operated area. In the case of the hand it means avoiding grasping and working with the hand, in the case of the leg - limiting walking and lifting the limb.
• Avoid physical exertion,, bending and lifting in the first days.
• No smoking. This is the strongest factor you can influence - nicotine constricts the small vessels, which are exactly the ones on which the blood supply to the graft depends.
• Report yourmedications, especially anticoagulant and antiplatelet medications - do not stop taking them yourself.
• Report for scheduled inspections, also to receive histopathological results.
• Protect the scar from the sun for the following months - fresh scars and grafts discolor easily.

It is worth expanding on the point about smoking, because it is sometimes neglected. The transplant in the first days depends on the microcirculation in the wound bed. Substances contained in tobacco smoke constrict vessels and impair oxygen delivery - and this directly translates into the risk of graft necrosis. A break from smoking around the procedure has a real, measurable importance here.

Likewise with movement. A transplant on the back of the hand in a person who uses the hand normally for the first few days is in a worse situation than an identical transplant in a patient who spares the hand. Immobilization is not excessive caution - it is part of the treatment.

How the transplant heals and what it will look like

In the first days after exposure, the graft usually looks disturbing: it is pale, bluish, darker than the surrounding area, sometimes covered with a scab. This is a normal stage and does not mean failure yet. Assessment of graft acceptance is only possible after a few days.

The target cosmetic effect takes many months to build. It's worth knowing in advance what to expect:

• the transplanted skin usually differs slightly in shade and structure from the surroundings,
• the graft border is sometimes visible, although it blurs over time,
• the area may initially be slightly sunken or, on the contrary, slightly raised,
• sensation in the graft returns gradually and may be incomplete,
• transplanted skin does not have sweat and sebaceous glands to the same extent as the natural skin, so it is sometimes drier,
• a linear scar remains in the donor site,
• the final appearance is assessed after many months, not after a few weeks.

The honest expectation is: the goal of the transplant is durable and safe coverage of the defect and preserving the shape of the area - rather than making the skin indistinguishable from the surrounding skin. With a well-planned treatment, the effect can be very good, but the difference is usually only noticeable up close.

Possible complications

• Hematoma under the graft — the most common cause of failure; moves the graft away from the ground.
• Collection of serous fluid — works similarly to a hematoma.
• Wound infection — requires treatment and may worsen transplant acceptance.
• Partial graft necrosis — healing then proceeds more slowly, usually without the need for a second procedure.
• Complete graft necrosis — rarer, but possible; requires repeated reconstruction or healing by granulation.
• Discoloration or discoloration within the graft.
• Abnormal scarring, including hypertrophic scars.
• Sensory disturbances in the area of ​​the graft and donor site.
• Scar at the donor site and transient pain in this area.
• Graft shrinkage during healing, which may affect the shape of the area.

The risk is increased by smoking, uncontrolled diabetes, coagulation disorders and anticoagulant treatment, peripheral vascular disease, old age, a location with poorer blood supply - such as the lower leg - and failure to follow immobilization recommendations.

People prone to excessive scarring should report this before the procedure. This influences incision planning, donor site selection, and postoperative recommendations.

When the procedure extends beyond the outpatient setting

Not every skin transplant can be performed in the office, and it is worth saying this clearly before the patient makes an appointment for a procedure that is not possible in this mode.

Situations requiring hospital conditions or a specialist center include, among others: extensive defects, burns, reconstructions requiring more complex techniques, procedures in internal medicine patients, the need for general anesthesia, wounds requiring long-term preparation of the substrate, as well as extensive cancers requiring multidisciplinary treatment.

Qualification is therefore also about assessing whether a given procedure can be safely performed on an outpatient basis - and if not, directing the patient to the right place rather than undertaking the procedure in inappropriate conditions.

Most common myths

• "Skin is taken from a donor." No. In these procedures, the graft comes only from the patient himself.
• "A transplant always requires a hospital." No. Selected, small transplants are performed on an outpatient basis under local anesthesia.
• "After the transplant, the skin looks like your own." No. The difference in shade and structure usually remains noticeable up close.
• "The dressing can be removed earlier to see." No. This is one of the most common causes of failure.
• "A bluish color of the graft means it has not been accepted." No. This is a typical stage of healing; evaluation is possible after a few days.
• "Smoking doesn't matter for such a small procedure." No. This is the strongest modifiable risk factor for graft necrosis.
• "Graft and skin flap are the same." No. The lobe retains its own blood supply, the graft is cut off from it.
• "The donor site leaves no trace." No. A scar remains, although it is planned to be well hidden.

Do you have a lesion that needs removal in a place where there is little skin?

The method of wound closure is planned before the procedure, not after it. During the consultation, we will assess the change and discuss which reconstruction method will be appropriate in your case.

Surgical procedures at the Island of Friendly Medicine in Gdańsk

At the Island of Friendly Medicine doctor. Piotr Rak consults patients with skin lesions requiring removal. The qualifying visit includes assessing the lesion, planning the scope of excision, and discussing how to close the wound - from direct suturing to reconstruction using a skin graft.

Lesions are removed with histopathological examination. If the scope of the procedure goes beyond outpatient conditions, the patient is referred to a center with appropriate facilities. The current scope of treatments, availability of dates and prices should be confirmed during registration.

FAQ - skin graft

Where does the graft skin come from?

Only from the patient himself, from another area of ​​his body. The donor site is selected so that the color and thickness of the skin match the area to be covered and the scar remains well hidden.

Can a skin transplant be done on an outpatient basis?

Selected, small transplants yes - under local anesthesia, back home the same day. Extensive defects, burns and complex reconstructions require hospital conditions.

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

The flap retains its own blood supply and remains connected to the tissue from which it comes. The graft is completely cut off from the vessels and in the first days it feeds from the wound base.

Why does the dressing have to be tight?

Because the graft only survives if it adheres tightly to the substrate. The hematoma, fluid or movement pushes it away from the bottom of the wound and prevents circulation from being restored.

Can I remove the dressing earlier?

No. Removing the dressing yourself before the scheduled date is one of the most common causes of failure. The date of the first change is set by the operator.

Does the procedure hurt?

It is performed under local anesthesia covering both the lesion area and the donor site. After the procedure, discomfort is typical, also in the area where the skin was taken.

How long does it take for the transplant to heal?

The first days determine the acceptance of the graft, and superficial healing occurs in the following weeks. The final appearance is assessed after many months. Specific dates are provided by the operator.

Why does the graft look blue and dark?

This is a typical healing stage in the first days after exposure. It does not mean failure - evaluation of the acceptance of the graft is only possible after a few days.

Will the graft be visible?

Usually yes, at least up close. The transplanted skin differs slightly in shade and structure, and the border is sometimes visible, although it blurs over time. The aim of the procedure is to permanently cover the defect and maintain the shape of the area.

Why does smoking matter?

Nicotine constricts small vessels, and the transplant in the first days depends on the microcirculation in the wound bed. Smoking significantly increases the risk of graft necrosis.

What if the transplant doesn't take?

Partial necrosis usually does not require repeated treatment - healing progresses more slowly, under a dressing. In case of complete necrosis, repeated reconstruction or healing by granulation may be necessary.

Who performs such treatments at WMP?

On the WMP website, MD. Piotr Rak is described as a surgeon who performs surgical procedures, including removal of skin lesions. The range of treatments that can be performed on an outpatient basis and the availability of dates are confirmed by registration.
