A multimodal approach to the treatment of extensive burn scars: a modified subcision technique for intralesional delivery of corticosteroid and 5-fluorouracil in combination with several procedural laser therapies; a case report.

Abstract

Introduction: Hypertrophic scars and keloids are challenging to manage due to recurrence and often sub-optimal response to treatment. There is a lack of both definitive treatment standards and randomised controlled trials comparing therapeutic options. While a wide array of procedures has been utilised to improve traumatic burn scars, such interventions have been used with varying degrees of success. Some reported methods include intralesional injections of anti-inflammatory and anti-mitotic medications, laser-based therapy, topical therapies, cryotherapy, silicone gel sheeting, pressure therapy, radiotherapy and reconstructive surgery.

Case: We report a case of extensive traumatic burn scarring on the head and neck successfully treated with a multimodal approach comprised of an infrequently used modified subcision technique to deliver alternating intralesional injections of anti-inflammatory (high-dose steroid) and anti-metabolite (5-flurouracil) concurrently with a series of laser (epilatory, vascular and fractional) treatments.

Methods: Our treatment modality utilised a subcisional technique to deliver intralesional steroid and anti-metabolite medications directly into scar tissue to downregulate inflammation and inhibit collagen synthesis. Alexandrite, fractional and pulsed dye laser therapy was employed to improve skin texture, reduce dyschromia and reduce tissue burden of hypertrophic scar and keloid tissue, resulting in improved mobility and skin elasticity.

Conclusion: Our case supports a combined medical and procedural, subcisional, approach to successfully treat a patient with extensive hypertrophic scarring and keloid formation with associated hair entrapment after a head and neck burn.
