Every surgical procedure and significant wound leaves a scar. While the body does a remarkable job of healing itself, scars do not always mature the way we hope — some remain red and raised for months, others become thick and rope-like, and some cause tightness or restrict movement. Scar revision surgery is a set of techniques designed to improve the appearance or function of an existing scar, and for many patients the results are genuinely life-changing.
What Can Scar Revision Achieve?
It is important to be honest from the outset: no treatment can make a scar completely invisible. What scar revision can do is make a scar significantly less noticeable — flatter, lighter, smoother, less conspicuous, or better aligned with natural skin creases. The goal is an improved scar, not the absence of one.
Types of Problematic Scars
Hypertrophic scars are raised, red, and firm but remain within the original wound boundary. They often develop in areas of high tension (across joints or on the chest) and may improve spontaneously over 1–2 years. When they do not, treatment can accelerate improvement significantly.
Keloid scars extend beyond the original wound margins and do not regress spontaneously. They are more common in patients with darker skin tones and in certain body regions such as the earlobes, upper chest, and shoulders. They can be itchy, tender, and disfiguring. Management is more challenging than for hypertrophic scars.
Contracture scars occur when a wound heals with tightening of the skin, restricting movement. They are common after burns but can occur after any wound that crosses a flexion crease. Surgical release and skin grafting or flap reconstruction may be required.
Wide or stretched scars occur when a wound is under tension during healing, resulting in a broad, flat scar. Re-excision with careful tension-free closure and layered suturing can produce a much finer scar.
Depressed or pitted scars sit below the level of the surrounding skin, as seen with chickenpox or acne. Subcision, filler, or resurfacing treatments may help.
Non-Surgical Options
Before recommending surgery, a specialist will consider whether non-surgical treatments might achieve a satisfactory result:
- Silicone gel sheets or gel: First-line treatment for hypertrophic and keloid scars; worn for 12+ hours per day for at least 3 months.
- Intralesional steroid injection: Highly effective for keloids and hypertrophic scars — flattens, softens, and reduces redness.
- Pressure therapy: Used after burns and extensive scarring.
- Laser resurfacing: Can improve redness, texture, and surface irregularity.
Surgical Scar Revision Techniques
Simple re-excision and layered closure: The old scar is removed and the wound re-closed meticulously in layers to minimise tension on the skin surface. Best for wide or suboptimally closed scars.
Z-plasty: A geometric technique using a Z-shaped incision to lengthen a scar, change its direction, or release a contracture. Highly effective for linear scars crossing joint flexion creases and for scars running against the natural skin tension lines.
W-plasty and geometric broken line closure: Break up a long linear scar into irregular segments that are less visible to the human eye, which preferentially detects straight lines.
Skin grafting and flap surgery: Required for more complex situations — large contractures, defects too large to close primarily, or where local tissue is unavailable.
When Is the Right Time for Scar Revision?
Most surgeons recommend waiting at least 12–18 months after the original injury before undertaking scar revision, as scars continue to mature and improve during this period. Operating too early risks a similar outcome. There are exceptions — rapidly worsening keloids, or scars causing functional problems — where earlier intervention is justified.
