Burn injuries are among the most complex challenges in reconstructive surgery. The physical damage — to skin, underlying tissue, and sometimes deeper structures — often requires multiple procedures over months or years. But modern reconstructive techniques have transformed what is achievable, restoring both function and appearance for many patients.
Understanding Burn Injuries
Burns are classified by depth. Superficial (first-degree) burns affect only the outer skin layer and heal without surgery. Partial-thickness (second-degree) burns involve deeper layers and may or may not require surgical intervention. Full-thickness (third-degree) burns destroy the entire skin thickness and always require surgical reconstruction. The extent of the burn — measured as a percentage of total body surface area — also determines the urgency and complexity of treatment.
The Goal of Burn Reconstruction
Reconstruction addresses several interconnected goals: restoring skin coverage over burn areas, releasing contractures (tightened scar tissue that restricts movement), improving the appearance of hypertrophic scars and keloids, and rebuilding areas with significant tissue loss. The priority is always function first — ensuring joints can move freely, airways and eyelids function properly — followed by aesthetic improvement.
Skin Grafting
Skin grafting is often the first reconstructive step for areas of full-thickness skin loss. Healthy skin is taken from an unaffected donor area (such as the thigh or back) and applied to the recipient site. Split-thickness grafts (taking a partial layer of skin) are most common. The grafted skin integrates with the wound bed over one to two weeks. Donor sites heal on their own. Grafts often look somewhat different to surrounding skin in colour and texture initially, but improve over time.
Flap Surgery
For areas where a simple graft is insufficient — deep wounds, areas over joints, or regions requiring more robust tissue — flap surgery may be used. A flap moves tissue (including its blood supply) from one area to another. Local flaps use nearby tissue; free flaps transplant tissue from a distant site using microsurgery. Flaps provide more durable coverage with better functional and aesthetic outcomes in complex cases.
Scar Management and Contracture Release
Even after initial wound closure, burn reconstruction continues. Hypertrophic scars — raised, firm, red scars — develop in many burn patients. These are treated with compression garments (worn 23 hours a day for 12–18 months), silicone sheets, steroid injections, and laser therapy. Contractures — when scars tighten across joints and restrict movement — may require surgical release with grafts or flaps to restore range of motion.
Tissue Expansion
For reconstruction of larger areas, tissue expansion is a powerful technique. A silicone balloon (expander) is placed under the skin near the affected area and gradually inflated over weeks to months, stretching the skin. This expanded skin is then used to reconstruct the adjacent scarred area, providing skin that matches perfectly in colour and texture. It is commonly used on the face, scalp, and neck.
Planning Your Reconstruction Journey
Burn reconstruction is not a single event — it is a programme. The timeline depends on the severity of injury, the areas affected, and how the body responds to each stage of treatment. Patients typically undergo reconstruction in stages, with periods of consolidation between procedures. A clear surgical plan, realistic expectations, and a committed patient-surgeon relationship are essential for the best outcomes.
