Meikle B, Simons M, Mahoney T, Reddan T, Dai B, Kimble RM, Tyack Z. Ultrasound measurement of traumatic scar and skin thickness: a scoping review of evidence across the translational pipeline of research-to-practice. BMJ Open 2024; 14:e078361. [PMID: 38594186 PMCID: PMC11015304 DOI: 10.1136/bmjopen-2023-078361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 03/18/2024] [Indexed: 04/11/2024] Open
Abstract
OBJECTIVES To identify the ultrasound methods used in the literature to measure traumatic scar thickness, and map gaps in the translation of these methods using evidence across the research-to-practice pipeline. DESIGN Scoping review. DATA SOURCES Electronic database searches of Ovid MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature and Web of Science. Grey literature searches were conducted in Google. Searches were conducted from inception (date last searched 27 May 2022). DATA EXTRACTION Records using brightness mode (B-mode) ultrasound to measure scar and skin thickness across the research-to-practice pipeline of evidence were included. Data were extracted from included records pertaining to: methods used; reliability and measurement error; clinical, health service, implementation and feasibility outcomes; factors influencing measurement methods; strengths and limitations; and use of measurement guidelines and/or frameworks. RESULTS Of the 9309 records identified, 118 were analysed (n=82 articles, n=36 abstracts) encompassing 5213 participants. Reporting of methods used was poor. B-mode, including high-frequency (ie, >20 MHz) ultrasound was the most common type of ultrasound used (n=72 records; 61% of records), and measurement of the combined epidermal and dermal thickness (n=28; 24%) was more commonly measured than the epidermis or dermis alone (n=7, 6%). Reliability of ultrasound measurement was poorly reported (n=14; 12%). The scar characteristics most commonly reported to be measured were epidermal oedema, dermal fibrosis and hair follicle density. Most records analysed (n=115; 97%) pertained to the early stages of the research-to-practice pipeline, as part of research initiatives. CONCLUSIONS The lack of evaluation of measurement initiatives in routine clinical practice was identified as an evidence gap. Diverse methods used in the literature identified the need for greater standardisation of ultrasound thickness measurements. Findings have been used to develop nine methodological considerations for practitioners to guide methods and reporting.

Abstract
OBJECTIVE To evaluate and explore the efficacy of CO2 fractional laser in treating post-burn hypertrophic scars in children through Meta-analysis. METHODS English databases (PubMed, Web of Science and The National Library of Medicine), as well as Chinese databases (China National Knowledge Infrastructure and Wanfang Data) were searched. RevMan 5.3 software was used to data analysis. RESULTS A total of 10 pieces of literature were included, involving 413 children. Meta-analysis showed that: (1) The average Vancouver Scar Scale after surgery was significantly lower than that before surgery [weight mean difference (WMD) = -3.56, 95% confidence interval (CI):-4.53,-2.58, p < 0.001]; (2) After CO2 fractional laser, pigmentation [WMD = -0.74, 95% CI:-1.10,-0.38, p < 0.001], pliability [WMD = -0.92, 95% CI:-1.20,-0.65, p < 0.001], vascularity [WMD = -0.77, 95% CI:-1.09,-0.46, p < 0.001], height [WMD = -0.57, 95% CI:-0.95,-0.19, p < 0.001] were improved compared with those before surgery. (3) The average Visual Analogue Scale (VAS) after surgery was significantly lower than that before surgery [WMD = -3.94, 95% CI:-5.69,-2.22, p < 0.001]. (4) Both Patient and Observer Scar Assessment Scale (POSAS)-Observer [WMD = -3.98, 95% CI:-8.44,0.47, p < 0.001] and POSAS-Patient [WMD = -4.98, 95% CI:-8.09,-1.87, p < 0.001] were significantly lower than those before surgery. (5) Erythema and vesicles were the most common complications after CO2 fractional laser therapy, with an incidence of 4.09%. CONCLUSION CO2 fractional laser is beneficial to the recovery of hypertrophic scar after burn in children, and can effectively improve the scar symptoms and signs in children, with desirable clinical efficacy.

Abstract
Laser treatment has gained more and more importance in the therapy of scars during the last years. Scientific work, especially in children, is scarce on this topic and mostly with an insufficient number of cases or only subjective descriptions. Our study included 77 children from 2012 to 2022 with scars after thermal injury. These were treated at least three times or more by CO2 laser or in combination with pulsed dyed laser (PDL). Beforehand, scar texture and elasticity were determined by a skin elasticity analysis system. Regarding the subjective evaluation, a questionnaire was given to the patients or their parents. Further criteria were the Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS). A statistically significant improvement in elasticity was demonstrated in all scars of any age after each laser treatment. In addition, a significant correlation was found between the number of laser treatments and an increase in elasticity. The assessments of scars after one or more laser sessions by the observer as well as the patient showed a decreasing score in all categories with an increase in the number of laser therapies. The VSS score also improved significantly after each laser session. The mean score before treatment was about 7, after the first laser session, the mean score was already below 6 with a statistical significance. Ninety-six percent of the patients or their parents were satisfied with the laser therapy, and 90% wished to repeat the procedure. This work confirms, by means of the objectification by the scar measurement, the previous scientific works concerning a scar therapy by laser and emphasizes particularly that this can also be used without problems with children with symptomatic scars, contractures, or with cosmetically relevant scars.

Abstract
Significance: This body of work gives a concise and comprehensive overview for the clinician and scientist on the latest treatment modalities for hypertrophic scars (HTS) and keloids in the pediatric population, as well as the most promising methods of prevention currently being investigated. This review will serve as a guide to the clinician for treatment selection and as an efficient tool for the scientist to achieve a comprehensive overview of the scientific literature to guide their future experiments aimed at pathologic scar prevention. Recent Advances: Current studies in the literature suggest carbon dioxide (CO2) laser and E-light (bipolar radiofrequency, intense pulsed light, and cooling) are two of the most effective treatment modalities for HTS, while surgical excision+CO2 laser+triamcinolone injection was one of the most successful treatments for keloids. In animal models, drug impregnated electrospun nanofiber dressings offer encouraging results for HTS prevention, while Kelulut honey showed promising results for keloid prevention. Critical Issues: Treatment outcome reproducibility is hindered by small cohorts of patients, inadequate-follow up, and variability in assessment tools. Prevention studies show multiple ways of achieving the same result, yet fall short of complete prevention. Furthermore, some studies that have purported full prevention have not been validated. Future Directions: To establish a standard of care, large clinical trials of the most successful modalities in small cohorts are needed. The key for prevention will be validation in animal models of the most successful methods, followed by translational and clinical studies.

Abstract
Although we have numerous publications about the effect of fractional CO2 laser therapy for burn scars, quantitative data about its efficacy and safety are sparse. The purpose of this meta-analysis was to assess the efficacy and safety of fractional CO2 laser therapy for the treatment of burn scars. Pertinent studies were identified by a search of PubMed, Embase and Web of Science up to 20 September 2020. Weighted mean difference (WMD) was conducted to combine the results, and a random-effect model was used to pool the results. Publication bias was estimated using Begg and Egger's regression asymmetry test. Twenty articles were included. Our pooled results suggested that fractional CO2 laser therapy significantly improved the Vancouver Scar Scale (VSS) score (WMD = -3.24, 95%CI: -4.30, -2.18; P < 0.001). Moreover, the Patient and Observer Scar Assessment Scale (POSAS)-patient (WMD = -14.05, 95%CI: -22.44, -5.65; P = 0.001) and Observer (WMD = -6.31, 95%CI: -8.48, -4.15; P < 0.001) also showed significant improvements with the treatment of fractional CO2 laser therapy. Fractional CO2 laser significantly reduced scar thickness measured with ultrasonography (WMD = -0.54, 95%CI: -0.97, -0.10; P < 0.001). For other outcomes, including pigmentation, vascularity, pliability, and height of scar, vascularity and relief, laser therapy was associated with significant improvements. However, only the cutometer measure R2 (scar elasticity) (WMD = -0.06, 95%CI: -0.10, -0.01; P = 0.023) was significantly improved with the laser therapy, but cutometer measures R0 (scar firmness) (WMD = 0.03, 95%CI: -0.04, 0.09; P = 0.482) was not. Side effects and complications induced by fractional CO2 laser were mild and tolerable. Fractional CO2 laser therapy significantly improved both the signs and symptoms of burn scars. Considering potential limitations, more large-scale, well-designed RCTs are needed to verify our findings.

Abstract
BACKGROUND Various laser therapies have been introduced in scar management. However, pain during treatment has limited the application of laser therapy in pediatrics. OBJECTIVES To evaluate whether the use of the low-energy mode of a carbon dioxide (CO2 ) laser improves hypertrophic scars in a pediatric population. METHODS This prospective, randomized, split-scar trial was designed to assess the safety and efficacy of low-energy CO2 laser use. Patients aged <12 years with hypertrophic scars were enrolled. Each hypertrophic scar was equally divided into three parts: the two ends of each scar were randomly assigned to control and experimental groups, and the center portion was considered a transition zone and was not included in the analysis. A total of three laser treatments were performed at 1-month intervals. Scar scale scores 6 months after the final treatment was the primary outcome. Additionally, the Visual Analog Scale (VAS) was used to evaluate pain after each treatment. RESULTS Of the 23 patients enrolled, 20 completed the study. The total Patient and Observer Scar Assessment Scale (POSAS) score at the 6-month follow-up was significantly lower for the treated site (44.95 for the treated group vs. 64.85 for the control group, p < 0.0001). Both the patient and observer POSAS scores showed an obvious difference between the treated and control groups (19.95 vs. 29.95 for patient scores, respectively, p < 0.0001, and 26.00 vs. 34.90 for observer scores, respectively, p < 0.0001). All observer and patient scores describing pain, pruritus, color, stiffness, and thickness were statistically different and favored the treated site. No significant difference was found in patient score of irregularity. The average VAS therapeutic pain score was 3.5 ± 1.43 out of 10. CONCLUSIONS Low-energy CO2 fractional laser therapy improved hypertrophic scars in a pediatric population. Therefore, for children with hypertrophic scar, low-energy CO2 laser with less procedure pain may be more appropriate.

Abstract
BACKGROUND Hypertrophic scars are commonly seen in children and associated with pruritus, pain, functional impairment, and aesthetic disfigurement. Ablative fractional CO2 and pulse dye laser are emerging techniques to improve scar quality. Only limited data are available on children, nonburn scars, and patient-reported outcome. We aimed to investigate safety and outcome of repeated laser therapy for hypertrophic scars originating from burns and other conditions by means of patient- and physician-reported outcome measures. METHODS This was a retrospective before-after analysis of laser treatments in children with hypertrophic scars. Outcome was measured using Patient and Observer Scar Assessment Scale, Vancouver Scar Scale and Itch Man Scale. With respect to safety, laser- and anesthesia-related complications were analyzed. RESULTS Seventeen patients, aged 11.37 ± 4.82 years with 27 scars, underwent 102 distinct laser treatments, mainly combined CO2 and pulse dye laser (94%), with few CO2 only (6%). Vancouver Scar Scale total score before the first and after the first session decreased significantly from 7.65 ± 2.12 to 4.88 ± 1.73; Patient and Observer Scar Assessment Scale observer overall opinion also dropped from 5.88 ± 1.57 to 4.25 ± 1.70. Pruritus improved significantly. Patient age and timing of laser intervention did not have an impact on treatment response. Complications related to laser treatment were seen in 2% (wound infection, n = 2) and to anesthesia in 4% (insignificant n = 2, minor n = 1). CONCLUSIONS Combined laser therapy significantly improves quality, pain, and pruritus of hypertrophic scars in children. When provided by experienced laser and anesthesia teams, it is safe with a low rate of complications.

Abstract
For over several decades, 595-nm pulsed dye laser (PDL) has been used effectively, reducing erythema and improving the pliability and texture of burn scars. Children usually tolerate PDL treatment as it is non-invasive and causes only mild pain compared to other laser treatments. However, currently, there are limited data on scar management in children who underwent PDL treatment, especially for Fitzpatrick skin types III and IV. The objective of the study was to identify the optimal parameters for the PDL treatment that induce inhibitory effects on scar tissue in children with Fitzpatrick skin types III and IV. Besides, the study assessed the usefulness of high-frequency ultrasound (20 MHz) and laser Doppler flowmetry in assessing these lesions. A total of 165 (79 males and 86 females) children with hypertrophic scars treated by PDL were assessed by the Vancouver scar scale (VSS), high-frequency ultrasound (20 MHz), and laser Doppler flowmetry. The parameters used for the 595-nm PDL treatment were pulse duration of 0.45 ms, fluence between 5 and 9 J/cm2, a spot size of 7 mm, and treatment intervals from 3 to 8 weeks. There were no significant differences between pretreatment and post-treatment in terms of the distribution of sex, type of skin color, and low and high fluences. While the mean scores of all scar parameters based on VSS, except thickness and pliability between pre and post-treatment, showed significant differences in ≤3-year-old children vs. to >3-year-old children, except for the subscore, a significant improvement was observed when PDL was initiated within 4 to 6 months of the scar age. In Chinese children with Fitzpatrick skin types III and IV, early intervention, appropriate treatment intervals, and low fluence of PDL were optimal parameters in treating hypertrophic burn scars. The combined high-frequency ultrasound and laser Doppler flowmetry assessment of scars helped assess these lesions and compare the efficacy of different treatment modalities.

Abstract
Burn injury can cause abnormal healing and pathologic scar formation that significantly impairs patients' ability to return to baseline levels of functioning. Quality of life can be significantly diminished due to pain, stiffness, contracture, and the psychological burden of disfigurement. Traditional scar therapies such as silicone sheeting and compression garments are highly reliant on patient compliance, and have not demonstrated satisfactory efficacy. Even more invasive therapies such as intralesional medication delivery or surgical contracture release have high recurrence rates. Recently, fractional CO2 laser therapy has emerged as a promising treatment modality for burn scars, but there is a lack of recent studies that aggregates extant data to demonstrate outcomes after laser therapy. To address this, we conducted a systematic review and meta-analysis to determine the efficacy of fractional CO2 lasers in treating burn scars, and found that laser therapy alone yielded statistically significant improvements in scar profiles. There were very few reports of adverse effects, most treatments were provided as outpatient, and both patient and burn practitioners reported high satisfaction. By sharing our findings, we hope that more burn practitioners will consider adopting laser therapy as a safe and cost-effective first-line therapy for burn scar management.

Abstract
BACKGROUND Hypertrophic scarring and keloid can cause significant emotional and physical discomfort. Cosmetic appearance, functional limitations, pain and pruritus form a degree of impairment. While the etiology is not fully known, there is a wide array of treatment options, which include excision, radiation, cryotherapy, silicone gel sheeting, and intralesional injections. A relatively new modality is laser therapy. While results are promising, the number of different laser systems is substantial. This review evaluates the available evidence regarding outcomes on specific objective characteristics (i.e., erythema, pigmentation, height, and pliability) of the different laser systems. METHODS A systematic literature review was performed using MEDLINE, Cochrane Library, and EMBASE. Data on scar characteristics were extracted from scar scales Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS), and from objective measurement tools. RESULTS Heterogeneity was seen in a lot of aspects: maturity of scar, origin of scar, follow-up, and number of treatments. The fractional ablative lasers CO2 10,600 nm and Er:YAG 2940 nm were found to produce the best results regarding erythema, height, and pliability, while the flash lamp-pumped pulsed dye laser (PDL) 585 nm scored slightly below that. CONCLUSIONS Laser systems, and specifically the fractional ablative lasers CO2 and Er:YAG, improved various characteristics of excessive scarring. An overview of preferred laser modality per scar characteristic is presented. Accounting for the methodological quality and the level of evidence of the data, future research in the form of randomized trials with comparable standardized scar scales is needed to confirm these results.

Ablative fractional laser treatment of hypertrophic burn and traumatic scars: a systematic review of the literature. Arch Dermatol Res 2020; 313:301-317. [PMID: 32926192 DOI: 10.1007/s00403-020-02135-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 08/13/2020] [Accepted: 08/26/2020] [Indexed: 10/23/2022]
Abstract
Hypertrophic scars (HTS) following burns and other trauma and are associated with significant functional and psychosocial impairment. Ablative fractional lasers (AFLs) are increasingly being applied in the treatment of HTS supported by a rapidly expanding multidisciplinary base of literature. The multidisciplinary authors sought to evaluate existing literature, provide context and identify gaps, and make recommendations for a path forward. A systematic review was conducted to identify literature pertinent literature through September 2019. Retrospective cohort, randomized controlled trials, quasi-randomized controlled trials, observational prospective cohort, or case series with five or more subjects with hypertrophic scars incurred from burns and related trauma were considered. Twenty-two of the 23 evaluated studies documented statistically significant and/or meaningful qualitative improvements in nearly all outcome measures. Adverse events were generally infrequent and minor. Significant heterogeneity was observed among the studies included in this systematic review, precluding metaanalysis of pooled data. There is abundant existing literature on the use of AFLs in the management of HTS but study heterogeneity limits generalizability. Future studies should prioritize standardized protocols including assessments of function and quality of life.

Lasers Surg Med 2020; 53:227-235. [PMID: 32432374 DOI: 10.1002/lsm.23262] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 05/08/2020] [Accepted: 05/09/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND OBJECTIVES There has been reports on fractional CO2 laser successfully improving contracture scars that impair the function of a joint. It seems that certain contracture problems could be solved by laser instead of surgery. However, the clinical application could be difficult when the efficacy of the method remains unknown. The purpose of this study is to report the releasing capacity of the fractional CO2 laser on contracture scars based on a defined treatment method. STUDY DESIGN/MATERIALS AND METHODS We conducted a retrospective study in patients with limited function in joints caused by contracture scars. Fractional CO2 laser and our "3D mesh releasing" protocol were applied. The primary outcome was the improvement measured in range of motion (ROM) of the relevant joint before all intervention and 6 months after the last treatment. RESULT From November 2016 to January 2018, 11 joints of 10 cases were treated by the fractional CO2 laser. Patients went through 2.27 (standard deviation [SD] 1.42, 1-5) sessions. The average progress of ROM before and 6 months after all treatments was 19.13° (SD 10.25, P < 0.02). In six cases, we recorded that there was an 8.53° (SD 5.81, P < 0.02) of increase in ROM immediately after the laser session, and the average improvement reached up to 13.58° (SD 8.15, P < 0.02) after 2-3 months during the next follow-up. CONCLUSION The fractional CO2 laser could achieve functional improvement in contracture scars and it maintained its effect for at least 6 months. The "3D Mesh Releasing" protocol would help to standardize the treatment procedure. This modality has minimal-invasiveness and potentially could become a supplement to the current treatment choices for mild contracture scars. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Abstract
BACKGROUND AND OBJECTIVES There is currently intense multidisciplinary interest and a maturing body of literature regarding laser treatments for traumatic scars, but international treatment guidelines and reimbursement schemes have not yet caught up with current knowledge and practice in many centers. The authors intend to highlight the tremendous potential of laser techniques, offer recommendations for safe and efficacious treatment, and promote wider patient access guided by future high-quality research. STUDY DESIGN/MATERIALS AND METHODS An international panel of 26 dermatologists and plastic and reconstructive surgeons from 13 different countries and a variety of practice backgrounds was self-assembled to develop updated consensus recommendations for the laser treatment of traumatic scars. A three-step modified Delphi method took place between March 2018 and March 2019 consisting of two rounds of emailed questionnaires and supplementary face-to-face meetings. The panel members approved the final manuscript via email correspondence, and the threshold for consensus was at least 80% concurrence among the panel members. RESULTS The manuscript includes extensive detailed discussion regarding a variety of laser platforms commonly used for traumatic scar management such as vascular lasers and ablative and non-ablative fractional lasers, special considerations such as coding and laser treatments in skin of color, and 25 summary consensus recommendations. CONCLUSIONS Lasers are a first-line therapy in the management of traumatic scars and contractures, and patients without access to these treatments may not be receiving the best available care after injury. Updated international treatment guidelines and reimbursement schemes, additional high-quality research, and patient access should reflect this status. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Abstract
Significance: Hypertrophic scars, keloids, and burn injuries of the skin have a significant impact on patients' lives and impact the health care system tremendously. Treating skin wounds and lesions can be challenging, with a variety of choices available for treatment. Scar and burn managements range from invasive, surgical options such as scar excision to less invasive, nonsurgical alternatives such as laser therapy or topical drug application. Recent Advances: Laser treatment has become increasingly popular, with a growing body of research supporting its use for scars and burns. Numerous methods are available for the treatment of these skin diseases, including different nonsurgical laser therapies. Critical Issues: To date, the optimal treatment method for scars, keloids, and burn injuries of the skin has not yet been established, although it is an area of increasing clinical concern. Future Directions: This review provides an updated summary of the treatment of scars and burn wounds of the skin using different laser treatments, including the most recent technologies. It addresses their indications, mechanisms of action, differences, efficacies, and complications.

Abstract
Objective: Scar biology is a territory less understood. The search for ideal treatment of keloid continues. The aim of this study was to compare the role of CO2 laser, triamcinolone (TAC), and verapamil in the treatment of keloid. Approach: A randomized parallel-group study was conducted in which 60 patients were randomly allocated to three groups from May 2017 to April 2018. First group received fractional CO2 laser therapy, second group received triamcinolone, and third group received intralesional verapamil. Outcomes were evaluated using Vancouver scar scale score at 3 weekly intervals for 6 months. Results: There was a reduction in scar height, vascularity, and pliability in all the three groups. However, pigmentation was not completely resolved by any of the three modalities. The response was fastest in case of triamcinolone followed by verapamil and laser, which was statistically significant. There was reduction in pain and pruritus in all the three groups and lesser injection site pain with verapamil. There was some amount of charring with CO2 laser. Innovation: Our study provides evidence that TAC has the fastest response in treating keloids when compared to other modalities. Scar pigmentation is the parameter that is not completely resolved by TAC, verapamil, or CO2 laser. Conclusion: The study revealed that fractional CO2 laser and verapamil are as efficient as triamcinolone acetonide (TAC) for treating keloids, except it takes longer for laser and verapamil to act compared to TAC. Verapamil can be used as an alternative treatment modality that is cost-effective with minimal adverse effects.

Abstract
Hypertrophic scar continues to be one of the leading reasons for surgical and non-surgical treatments after burn healing. Facial post-burn hypertrophic scars can cause severe functional and emotional disability, as they are usually difficult to conceal. Numerous nonsurgical and surgical therapies have been used for the treatment of hypertrophic scars. This study describes the combination of bipolar radiofrequency, intense pulsed light and cooling (given the collective term 'E-light'), and reports the outcomes of its use in the treatment of post-burn facial hypertrophic scars in a series of sixty-five patients in the pediatric age group. There were no reports in the literature of the use of this modality (E-light) in the treatment of facial post-burn hypertrophic scars in pediatric patients. Results showed that the mean decrease in total VSS score for all patients was 5.8. Regarding the satisfaction of the parents of our patients, 66.15% rated the result excellent, 24.61% rated it good and 9.23% rated it fair. We received no poor ratings for the final result, with a significant reduction in total Vancouver scar scale after treatment (P-value = 0.000). The E-light therapy technique studied in this work is effective, safe and economical if compared to other treatment modalities that can be used in the management of facial post-burn hypertrophic scars.

Abstract
The objective of this systematic review was to assess the effectiveness of laser therapy for the treatment of hypertrophic burn scars. Improvements in scar symptoms following laser treatment were reported in 11 of the 12 included studies. However, issues related to overall quality and risk of bias were present in all studies. As a result, there is insufficient scientific evidence to determine the effectiveness of laser therapy from this systematic review. Future studies that use more rigorous study designs such as randomized controlled trials are needed to support the use of laser therapy for hypertrophic burn scars.

Percutaneous collagen induction as an additive treatment for scar formation following thermal injuries: Preliminary experience in 47 children. Burns 2017; 43:1097-1102. [PMID: 28283308 DOI: 10.1016/j.burns.2017.02.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Revised: 01/24/2017] [Accepted: 02/15/2017] [Indexed: 11/23/2022]
Abstract
BACKGROUND Thermal injuries are one of the most physically and psychologically devastating causes of pediatric trauma. Post-traumatic sequelae such as hypertrophic scars and contractures often result in long lasting morbidity and disfigurement. Conservative therapy, including pressure garments and silicone, is the gold standard for scar management in the pediatric population. Most recently percutaneous collagen induction (PCI) was introduced as an alternative treatment in adults. The aim of this report was to share our experience with PCI in children and adolescents in scar management following thermal injuries. PATIENTS AND METHODS Between July 2013 and February 2016, a total of 99 PCI treatments were performed on forty-seven children and adolescents for scar formation following thermal injuries in this retrospective study. A medical roller device (Dermaroller®, Dermaroller GmbH, Wolfenbüttel, Germany) with 2.5mm long needles was used. All procedures were carried out under general anesthesia. At the end of the operation vitamin A and vitamin C oil (ENVIRON® AVST Body Oil; Environ Skin Care, Pty. Ltd., Cape Town, South Africa) was applied topically. Photographs were taken before and a minimum of 4 weeks after the first PCI in order to document the effect on scar tissue. These images were graded according to the Vancouver Scar Scale (VSS). RESULTS The median age at the time of the first PCI was 8.3 years (range, 0.8-21.2 years). The median time interval between the injury and PCI was 18 months (range, 4-170 months). There were no intraoperative problems noted. Minor postoperative complications occurred in 2 patients (4.3%). All patients reported subjective improvement and were satisfied with the procedure and the results. Pre- and post-treatment photographs were available in 40 patients, and overall VSS scores improved post-treatment in all patients. Following a single PCI treatment, scar vascularity, pliability and height all improved, however there was no statistically significant effect on pigmentation. CONCLUSIONS PCI is an enrichment of the armamentarium for scar treatment following thermal injuries in children and adolescents. Further prospective studies are recommended regarding the optimal timing for this treatment and long term outcome in the pediatric population.
