Clinical application of 10 600 and 1540 nm laser therapy in post-burn functional impairment: a case report

Introduction: Extensive burn injury can result in hypertrophic, retracting scars that, based on their location, can lead to reduced functionality for the patient. This study reports the clinical case of a young man who presented at the clinic with second-degree burn injuries to the chin, hand, and forearm. Case presentation: The patient complained of pruritus and had difficulty moving his hand, which impacted his professional life. The scars were treated with the sequential emission of two laser wavelengths: 10 600 and 1540 nm. The patient was very satisfied with the outcome and was able to resume his work. Discussion: Recent histological studies have demonstrated that the sequential emission of the CO 2 laser at 10 600 and the 1540 nm non-ablative laser extends the thermal effects on the micro-ablative zone, stimulating and enhancing collagen remodeling compared with the use of CO 2 alone. The sequential emission of these two wavelengths has been proven to be a valid treatment choice for skin remodeling for aesthetic purposes, with shorter healing times and a lesser risk of hypopigmentation. Conclusion: This study used a combination of ablative and non-ablative lasers to remodel hypertrophic burn scars, achieving improved aesthetics, symptom relief, and restored hand function through the resolution of joint contractures.
