Post Burn Stigmata

Hypertrophic scars are raised, firm, erythematous (red) scars that remain within the boundaries of the original wound — they result from excessive collagen deposition during healing of deep partial and full thickness burns. They typically mature and flatten over 12 to 24 months but can cause significant pruritus and cosmetic concern. Keloids extend beyond the original wound margins, invade surrounding normal skin, do not spontaneously involute, and are more common in patients of African, Asian, or Indian ethnicity. Burn contractures are a distinct pathology — linear bands of scar tissue crossing joints that progressively restrict range of motion, causing functional disability (inability to open the mouth, extend the elbow, pronate the forearm, or spread the fingers).

Custom-fitted pressure garments (compression garments) are medical-grade elastic garments precisely tailored to deliver 20 to 25 mmHg of sustained external pressure over healing burn scars. Pressure therapy reduces scar hypertrophy by: decreasing local blood flow (inducing relative hypoxia that shifts fibroblast activity toward scar maturation); mechanically flattening collagen bundles; and reducing mast cell degranulation (which drives itching and inflammation). Garments must be worn 23 hours per day for 12 to 24 months — the full scar maturation period. Compliance is the critical variable: patients who wear their garments consistently produce significantly flatter, softer, less pigmented scars than those who do not.

Burn contracture release is one of the most functionally transformative procedures in reconstructive surgery. Options depend on contracture severity and available surrounding tissue: Z-plasty is the workhorse technique for linear contracture bands — it mathematically lengthens the scar line by converting a single straight scar into interlocking diagonal limbs, breaking the contracture band and increasing range of motion by up to 75%. Multiple Z-plasties or W-plasty are used for longer contractures. When local tissue is insufficient, release is covered with: local perforator flaps (freestyle propeller flaps for small defects), regional pedicled flaps, or free flaps (microsurgical transfer) for complex extensive contractures. Split-thickness skin grafting alone is reserved as a last resort, as it frequently re-contracts.

Laser resurfacing is now a mainstay of burn scar rehabilitation when deployed during scar maturation. Fractional ablative CO2 laser (fractional photothermolysis — 10,600 nm wavelength) ablates thousands of microscopic treatment zones within hypertrophic scar, creating channels that trigger new collagen remodeling, softening texture and reducing height. Pulsed Dye Laser (PDL — 585 or 595 nm) targets oxyhemoglobin in the superficial scar vasculature — reducing erythema (redness), post-burn telangiectasias, and pruritus by selective photothermolysis. Non-ablative fractional Nd:YAG improves deeper collagen remodeling with less downtime. A combined multi-laser protocol (PDL + fractional CO2) is most effective for thick, red, itchy hypertrophic scars.

The timing of reconstructive procedures after burns depends on the principle of scar maturity. Immature scars (erythematous, raised, firm, pruritic) are highly vascular, metabolically active, and will change substantially — operating during this phase risks poor healing, excessive bleeding, and inability to accurately assess the true deformity. Most burn scars reach maturity at 12 to 24 months post-injury (signified by becoming flat, pale, and soft). Conservative measures (pressure garments, intralesional steroid injections, laser therapy, physiotherapy) are deployed throughout maturation. Functional contractures limiting joint range of motion, threatening vision or airway (facial contractures), or causing growing deformity in children are exceptions — these are released early regardless of scar maturity due to functional urgency.

Severe burn disfigurement profoundly impacts identity, self-esteem, social interaction, intimate relationships, and professional life. Studies show that up to 30 to 40% of burn survivors experience clinically significant PTSD, depression, and social anxiety — independent of burn size — driven by visible facial scarring, body image disturbance, and trauma memory. At Olive, psychosocial rehabilitation is an integral component of burn reconstruction, encompassing: preoperative psychological assessment and counseling, realistic outcome expectation setting before each reconstructive stage, post-operative psychotherapy and support group referral, and coordination with burn survivor organizations for peer support. Functional and cosmetic reconstruction proceeds alongside psychological recovery, not instead of it.
