Laser-Assisted Scar Revision Surgery: Functional and Cosmetic Outcomes

Open Access

Abstract

Background: Scar formation following trauma, surgery, acne or burns often leads to functional impairment and cosmetic dissatisfaction. Laser-assisted scar revision surgery has emerged as a minimally invasive modality offering controlled dermal remodeling and improved aesthetic outcomes. However, real-world data from clinical laser centers in South Asia remain limited. Objective: To evaluate the functional and cosmetic outcomes of laser-assisted scar revision surgery among patients treated at a specialized dermatologic laser center. Methods & Materials: A retrospective observational study was conducted on approximately 220 patients treated between May 2023 and March 2026 at City Aesthetics, Advanced Skin Laser Center, Jashore. Patients with hypertrophic scars, keloids, post-surgical scars and post-traumatic scars were included. Fractional CO₂ laser and Nd:YAG laser modalities were used depending on scar type. Outcomes were assessed using Patient and Observer Scar Assessment Scale (POSAS), pain score and photographic comparison at baseline, 3 months and 6 months. Results: Most patients showed significant improvement in both cosmetic appearance and functional symptoms. Mean POSAS score improved from 68.4 ± 8.2 pre-treatment to 28.6 ± 6.1 at 6 months. Functional symptoms such as itching, tightness and pain improved in 82% of cases. Hypertrophic scars responded better than keloids. Adverse effects were minimal with transient erythema (18%) and mild hyperpigmentation (9%) being the most common. Conclusion: Laser-assisted scar revision is a safe and effective modality for improving both cosmetic and functional outcomes in diverse scar types. Fractional laser technology provides significant dermal remodeling with minimal complications. Further prospective multicenter studies are recommended.
