Scar Revision Surgery: Minimising Scars After Injury or Surgery

Scars are a natural part of the healing process, but when they are prominent, raised, discoloured, or cause functional problems, they can significantly affect a person's appearance and self-confidence. Scar revision surgery aims to improve the appearance of a scar so that it blends more naturally with the surrounding skin. Dr. Prasanna Somvanshi, a specialist plastic surgeon in Mumbai, offers a range of scar revision techniques at NH SRCC, SevenHills, Surya Hospital, HN Reliance, MRR Hospital, and Sushrusha Hospital.

Understanding Different Types of Scars

Not all scars are the same, and the type of scar determines the most appropriate treatment approach:

Hypertrophic scars: These are raised, red scars that remain within the boundaries of the original wound. They are caused by excess collagen production during healing and are common after burns, surgical incisions, and traumatic injuries
Keloid scars: Unlike hypertrophic scars, keloids extend beyond the original wound boundaries and continue to grow over time. They are more common in individuals with darker skin tones and can occur on the ears, chest, shoulders, and jawline
Atrophic scars: These are depressed or sunken scars, often seen after acne, chickenpox, or certain surgical procedures. The skin in these areas lacks adequate collagen support
Contracture scars: These scars tighten and pull the surrounding skin, often occurring after burns. They can restrict movement when they cross joints and may require surgical release
Wide or stretched scars: Sometimes a thin surgical scar gradually widens due to tension on the wound during healing. These scars are flat but cosmetically noticeable

When to Consider Scar Revision

Dr. Prasanna Somvanshi advises patients to wait at least 12 to 18 months after the original injury or surgery before considering scar revision. This allows the scar to fully mature and often results in natural improvement. However, certain situations may warrant earlier intervention:

Scars that cause functional limitation, such as contractures restricting joint movement
Actively growing keloid scars that do not respond to conservative treatment
Scars on the face or other highly visible areas that cause significant psychological distress
Scars that are painful, itchy, or tender

Scar Revision Techniques

Z-Plasty

Z-plasty is one of the most versatile techniques in plastic surgery. It involves making Z-shaped incisions on either side of the scar and transposing the resulting triangular flaps. This changes the direction of the scar so that it aligns more closely with the natural skin creases, making it less visible. Z-plasty is particularly effective for linear scars that cross skin tension lines or natural creases, and for releasing contracture scars.

W-Plasty

W-plasty involves excising the scar in a zigzag pattern, creating a series of small triangular interdigitating flaps. The resulting irregular scar line is less noticeable than a straight line because it breaks up the light reflection pattern. This technique is well-suited for long linear scars on the face.

Geometric Broken Line Closure

Similar to W-plasty but using irregular geometric shapes (triangles, rectangles, semicircles), this technique creates a random pattern that is even less perceptible to the eye. Dr. Somvanshi uses this advanced method for selected facial scars where optimal cosmetic outcome is critical.

Serial Excision

For wide scars, serial excision involves removing a portion of the scar in stages, allowing the surrounding skin to stretch between procedures. This is useful for large scars on the body where tissue expansion may not be practical.

Laser Treatment

Fractional CO2 lasers and pulsed dye lasers can improve scar colour, texture, and thickness. Laser treatment is often used as a standalone therapy for mild scars or as an adjunct to surgical revision. Multiple sessions may be required for optimal results.

Dermabrasion

Mechanical dermabrasion smooths the surface of raised scars by removing the upper layers of skin in a controlled manner. It is effective for blending the scar surface with surrounding skin, particularly for acne scars and superficial traumatic scars.

Steroid Injections

Intralesional corticosteroid injections (typically triamcinolone) are a first-line treatment for hypertrophic and keloid scars. The steroids reduce collagen production and can flatten raised scars over a series of injections administered every four to six weeks.

Timing and Planning

Dr. Prasanna Somvanshi takes a methodical approach to scar revision. During the consultation, the scar is carefully assessed for its type, location, orientation relative to skin tension lines, and impact on function and appearance. A customised treatment plan is then developed, which may combine multiple techniques for the best outcome. Patients are counselled that scar revision improves but does not completely eliminate a scar.

Recovery After Scar Revision

Recovery depends on the technique used. Most scar revisions are performed as outpatient procedures under local anaesthesia. Sutures are typically removed within five to seven days for facial scars and ten to fourteen days for body scars. Sun protection and silicone-based scar therapy are recommended for several months after the procedure to optimise the final result.
