3D Mesh Releasing Method: A Retrospective Analysis of Fractional CO2 Treatment on Contracture Scars

Scar Management and Dyschromia: A Summary Report from the 2021 American Burn Association State of the Science Meeting

Burn scars, and in particular, hypertrophic scars, are a challenging yet common outcome for survivors of burn injuries. In 2021, the American Burn Association brought together experts in burn care and research to discuss critical topics related to burns, including burn scars, at its State of the Science conference. Clinicians and researchers with burn scar expertise, as well as burn patients, industry representatives, and other interested stakeholders met to discuss issues related to burn scars and discuss priorities for future burn scar research. The various preventative strategies and treatment modalities currently utilized for burn scars were discussed, including relatively noninvasive therapies such as massage, compression, and silicone sheeting, as well as medical interventions such as corticosteroid injection and laser therapies. A common theme that emerged is that the efficacy of current therapies for specific patient populations is not clear, and further research is needed to improve upon these treatments and develop more effective strategies to suppress scar formation. This will necessitate quantitative analyses of outcomes and would benefit from creation of scar biobanks and shared data resources. In addition, outcomes of importance to patients, such as scar dyschromia, must be given greater attention by clinicians and researchers to improve overall quality of life in burn survivors. Herein we summarize the main topics of discussion from this meeting and offer recommendations for areas where further research and development are needed.

Congress Report on the Second World Congress of Global Scar Society with Scar Academy and Japan Scar Workshop

Pathological scars (including keloids, hypertrophic scars, and scar contractures) are present with high severity among certain populations, particularly in Asians and Africans who are highly prone to develop scars. Understanding the patho-mechanism that underlies scarring, such as mechanosignaling, systemic, and genetic factors, as well as optimal surgical techniques and integrated noninvasive therapeutic methods can guide clinicians to develop treatment protocols that can overcome these issues. This report summarizes a congress at Pacifico Yokohama (Conference Center) on December 19, 2021 involving researchers and clinicians from diverse disciplines who convened to discuss current clinical, preclinical, and most recent research advances in understanding pathological scarring, keloid and hypertrophic scar management, and research progress in wound healing. Presenters described the advances in scar therapies, understanding scarring mechanisms, and scar prevention and assessments tools. Moreover, presenters addressed the challenges during the COVID-19 pandemic and using telemedicine in management of scar patients.

Effects of multiple modes of UltraPulse fractional CO2 laser treatment on extensive scarring: a retrospective study

The main therapeutic options for extensive scarring (e.g., > 20% of the total body surface area, or TBSA) after burns and trauma have focused on conservative treatments, such as compression, moisturization, and topical agent application. However, these treatments may not achieve optimal effects due to the large size and complexity of the scars. UltraPulse fractional CO₂ laser treatment is a novel approach that is currently a subject of intense interest; this treatment is most widely used to improve texture, pliability, and pigmentation in all types of scars. However, no studies on the independent use of UltraPulse fractional CO₂ laser treatment for extensive scars have been reported. This retrospective study evaluated a total of 21 patients, whose scars covered 20 to 65% TBSA. Scar thickness was measured by ultrasonography before treatment. Personalized treatment modalities and parameters were set according to the scar type and thickness. Scar formation and treatment effects were evaluated by photography, the Patient and Observer Scar Assessment Scale (POSAS), and patients’ judgment of effectiveness. Where the scars covered joints, joint function was assessed by measuring the maximum range of motion (ROM). With laser therapy, scars became flatter and lighter; furthermore, pruritus, pain, and discomfort decreased significantly. POSAS scores significantly decreased after laser therapy, including the item scores for pain and pruritus. There were no instances of joint contracture, ROM reduction, apparent functional impairment, serious adverse events, or comorbidities. This study demonstrates the safety and efficiency of UltraPulse fractional CO₂ laser treatment for extensive scarring.
