The skin is our largest organ and our most important protective barrier. If skin is lost as a result of accidents, burns, tumour removal or severe infections, skin reconstruction is required. This is the core task of plastic and reconstructive surgery: restoring the body’s form and function.
This article provides you with a clear and concise overview of the fundamental principles and techniques that surgeons use to close skin defects safely and effectively.
What is skin reconstruction?
What is skin reconstruction?
Skin reconstruction encompasses all surgical procedures aimed at closing a skin and soft tissue defect. A defect is an area where tissue is missing.
The aim of the reconstruction is to restore the skin’s protective function, to facilitate wound healing and to achieve the best possible functional and aesthetic outcome.
The basic principle: the reconstructive ladder
When choosing the right method, plastic surgeons follow a logical principle known as the „reconstructive ladder“. As a general rule, they start with the simplest method and only resort to more complex techniques when necessary. However, for certain defects (e.g. those involving exposed structures), a higher-level technique is required immediately.
The stages of the Reconstructive Ladder:
- Secondary healing Minor, superficial wounds are sometimes left to heal on their own.
- Primary suture If the edges of the wound can be brought together without tension, a direct suture is the simplest solution.
- Skin graft In the case of extensive but superficial defects, skin is taken from another part of the body and grafted.
- Local flap surgery Tissue is moved from the immediate vicinity of the wound to cover the defect.
- Stalked lobe sculpture A block of tissue with its own blood supply is rotated from an adjacent area of the body into the defect.
- Free flap surgery (microsurgery) The most complex stage. A block of tissue containing an artery and a vein is completely severed from the body and reattached to the bloodstream at a different site under the microscope.

Skin graft
As explained in our detailed article on split-thickness skin grafting, this procedure involves grafting only skin that has no blood supply of its own. It is ideal for large, superficial wounds, such as those caused by burns.
Flap surgery
This is the crucial step towards more complex reconstructions. Unlike a simple skin graft, in a flap procedure an entire tissue package – consisting of skin, subcutaneous fat and often muscle as well – is moved or transplanted together with its own intact blood supply.
Advantages: Flap grafts introduce well-perfused, stable and voluminous tissue into a wound. They can also cover complex structures such as bones, tendons or nerves, where a simple skin graft would not heal.
Usage: They are the treatment of choice for deep, three-dimensional wounds, for example following tumour removal on the face or during breast reconstruction after a mastectomy.
Tissue expansion
In this technique, a silicone balloon (expander) is implanted beneath healthy skin near a defect (e.g. a large scar). Over a period of several weeks, this balloon is gradually filled with saline solution, thereby slowly stretching the skin. In this way, the existing skin is gradually expanded so that, later on, there is sufficient skin from the patient’s own body available to cover the defect.
Relevance to Plastic and Aesthetic Surgery
Mastery of these reconstructive techniques is at the heart of training to become a specialist in plastic and aesthetic surgery (often colloquially referred to as a cosmetic surgeon). It forms the basis for every safe and successful aesthetic procedure.
Reconstruction as the foundation for excellence in aesthetics
The ability to reconstruct a complex skin defect is directly applicable to the performance of cosmetic surgery:
- The principle of flap surgery is the basis of a modern tummy tuck, in which the navel is „pedicled“ – that is, its blood supply is preserved – and repositioned.
- Understanding the blood supply The condition of the skin is crucial for preventing wound-healing complications following a facelift.
- Techniques for covering defects form the basis for the safe management of rare but serious complications following cosmetic procedures.
Risks associated with skin reconstruction and financial protection for surgical procedures
Reconstructive procedures are often complex and carry associated risks. As they are medically necessary, the costs are usually covered by health insurance schemes. However, purely cosmetic procedures are excluded.
However, the principles of patient safety and risk management are universal. Liability insurance is specifically designed for the field of cosmetic surgery, where the financial risk of complications lies entirely with the patient – we would be happy to advise you on your insurance options.
Frequently Asked Questions (FAQ) on skin reconstruction
The key difference lies in the blood supply. A skin graft is simply a piece of skin without its own blood vessels, which must heal onto a well-perfused wound bed. A flap, on the other hand, retains its own intact blood supply and can therefore heal even on poorly perfused wounds.
Sensation is significantly reduced following a skin graft. In the case of flap surgery, if sensory nerves are also transplanted and reconnected using microsurgery, a good to very good restoration of sensation can be achieved.
The aim is to restore form and function as fully as possible. However, a reconstructed area will always differ from unaffected tissue and will leave visible scars.
