Ablative fractional laser treatment of hypertrophic burn and traumatic scars: a systematic review of the literature.

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.

Epidermolysis Bullosa Patients' Perception of Surgical Wound and Scar Healing.

BACKGROUND: There is limited evidence to suggest patients with epidermolysis bullosa (EB) have more postoperative wound complications than the general population. Despite this, the authors have noted reluctance among some surgeons to operate on these patients. OBJECTIVE: A cross-sectional study was designed to investigate postoperative wound and scar healing outcomes in patients with EB. METHODS: Patients were asked to complete the "Surgical Wound and Scar Healing in EB" questionnaire, and data gathered were analyzed. RESULTS: Forty-six patients completed the questionnaire for a total of 94 different surgical procedures. Five patients reported blistering at the surgical wound site. All 5 had generalized forms of EB. Four patients reported wound infections, and 1 patient reported wound dehiscence. The postoperative scar healed with keloid or hypertrophic scarring after 26% of the reported surgical procedures. CONCLUSION: Blistering at the postoperative site seems to be uncommon and particularly unlikely to occur in localized forms of EB. Postoperative wound infections and dehiscence are uncommon. Patients with EB may have a propensity to develop keloid or hypertrophic scarring. With these data, the authors hope clinicians have greater confidence in referring patients with EB for surgery, and surgeons more reassured about postoperative wound healing.

A systematic review and meta-analysis: Do absorbable or non-absorbable suture materials differ in cosmetic outcomes in patients requiring primary closure of facial wounds?

INTRODUCTION: Surgeons are often judged based on the cosmetic appearance of any scar after surgery rather than the functional outcome of treatment, especially when considering facial wounds. OBJECTIVE: We performed a systematic review of the literature to determine whether absorbable or non-absorbable suture materials result in different cosmetic outcomes for patients requiring primary closure of facial wounds. METHODS: An extensive systematic review was carried out to identify studies meeting our inclusion criteria. Risk of bias in each study was assessed using the Cochrane risk of bias assessment tool. Data were extracted from those articles that met our inclusion criteria, and statistical analysis was carried out using the Cochrane RevMan. RESULTS: We found no significant difference in any aspect of our analysis including Visual Analogue Cosmesis scale, Visual Analogue Satisfaction scale, infection, dehiscence, erythema or stitch marks. Most authors concluded that they prefer to use absorbable sutures. However, the overall quality of evidence is poor, and significant variation exists regarding the methods of assessment between papers. CONCLUSION: Use of absorbable suture material appears to be an acceptable alternative to non-absorbable suture material for the closure of facial wounds as they produce similar cosmetic results.

Endoscopic Thyroidectomy Using the Unilateral Axillo-breast Approach Versus the Modified Anterior Chest Wall Approach: A Prospective Comparative Study.

INTRODUCTION: Endoscopic thyroidectomy (ET) has become a well-established surgical technique that is mainly performed for benign thyroid lesions. Several endoscopic approaches are available, such as transaxillary, unilateral axillo-breast approach (UABA), modified anterior chest wall approach (MACWA), bilateral axillo-breast approach, and most recently the transoral approach and the robotic-assisted techniques. There is no recommended approach, because each approach has its own positive and negative attributes. We, herein, compare between UABA and MACWA in terms of surgical and cosmetic outcomes. METHODS: This prospective study was conducted from April 2016 to August 2017. Forty patients with unilateral benign thyroid lesions were selected. Of them, 20 patients underwent ET using UABA, and 20 patients underwent ET using MACWA. Gas insufflation was implemented for all patients. Clinicopathologic data, surgical outcomes, and cosmetic outcomes in both groups were analyzed. RESULTS: There was no significant difference between both groups in the clinicopathologic characteristics. The mean surgical time was significantly longer in the UABA group compared with the chest wall group (147.3 vs. 124.3 min). The postoperative pain scores were relatively lower in the UABA group compared with the MACWA group. We reported a higher rate of persistent paresthesia, neck contracture with swallowing discomfort, and hypertrophic scars in the MACWA group. Cosmetic satisfaction scores for patients who underwent UABA were higher than for those who underwent MACWA. CONCLUSIONS: Both approaches were similar in terms of safety, feasibility, and operative complications. Even though the surgical time was longer, patients who underwent the UABA reported relatively less postoperative pain, superior cosmetic results, scar perception, and patient satisfaction compared with MACWA.

The lived experience and quality of life with burn scarring-The results from a large-scale online survey.

A large-scale online survey was designed to both inform and direct the development of an online community healthcare hub for people living with scarring. Focussed areas of questioning were generated to gather information on psychological symptoms, scar support and knowledge of wounds and healing. Simple statistical data was produced on the severity, aetiology and location of scarring. A secondary data analysis of the survey responses was conducted on more focussed themes. This survey was completed by 1034 people living with scars, 119 of which had burn scarring. The results highlight that patients with burn scars have higher levels of pre-existing psychological difficulties, carry a greater number of scars and experience more symptoms. A lack of support is identified for patients with scars once they have been discharged by their healthcare provider. The most popular forms of support were chosen as face-to-face interaction or online support. Key areas of support were found to be psychology particularly for help with acceptance or coping methods, wound care advice and meeting with other patients with scars. For these patients, key themes in the psychological impact of scarring include appearance-related concerns, social anxiety, acceptance and coping, experience of symptoms, skin viability and survivorship.

The association of affective disorders and facial scarring: Systematic review and meta-analysis.

BACKGROUND: Facial scarring can have a dramatic effect on a patient's psychological health and wellbeing and present unique management challenges. This patient population remains poorly characterised in the contemporary literature. AIMS: To evaluate the prevalence of, and risk factors associated with affective disorders in adult patients with facial scars. METHODS: A systematic review was conducted using a protocol registered with PROSPERO and in line with the PRISMA statement. A comprehensive search of the literature was conducted using PubMed, MEDLINE, EMBASE, PSYCHInfo and The Cochrane Library. RESULTS: Twenty one studies were included, with a total of 2,394 participants. Using a random effects model, the weighted pooled prevalence of anxiety was 26.1% (95% CI 17.9%-36.3%) and the weighted pooled prevalence of depression was 21.4% (95% CI 15.4%-29.0%). Studies identified female gender, past psychiatric history and violent causation as factors associated with anxiety and depression. LIMITATIONS: Included studies were limited to those published in peer reviewed journals. Longitudinal trends in both anxiety and depression were limited by a short duration of follow up. CONCLUSIONS: There is a high and persistent burden of affective disorders in patients with facial scars. Additional research is required to further characterise this population and develop effective management strategies.

Satisfaction with Facial Appearance and Quality of Life after Treatment of Face Scars with a Transparent Facial Pressure Mask.

Treatment of facial hypertrophic scars and deformities has developed from the use of elastic fabric hoods to transparent facemasks. The clinical effects of these masks have been described. However, the psychological impact of wearing such a mask is not well documented. The aim of this study was to assess patients' satisfaction with their current facial appearance, to assess the end result of facemask therapy, and to assess the decision to have undergone facemask therapy by means of four different FACE-Q questionnaires. Out of the eligible 87 patients who completed the facemask therapy between January 2012 and November 2017, 42 filled out the questionnaires. These patients wore a custom-fabricated facemask because of facial hypertrophic scars and severe postsurgical facial irregularities. Patients who wore the mask 12 to 16 hours per day were significantly more satisfied with the end result compared with those who wore it 4 to 8 hours daily. Also, patients who wore the mask 8 to 12 and 12 to 16 hours each day were more satisfied to have undergone therapy compared with those who wore it 4 to 8 hours daily. Furthermore, patients who finished therapy 3 to 4 years and 4 to 5 years ago reported a significant higher satisfaction with facial appearance compared with those who completed therapy in a time period shorter than 1 year ago. Patients who finished therapy 3 to 4 years ago reported higher satisfaction with their facial appearance compared with those who finished therapy 2 to 3 years ago. Additionally, the Patient and Observer Scar Assessments Score (POSAS) showed a significant reduction between start and end of therapy. This study shows facemask therapy to result in long-lasting stable results. It also shows a longer daily wearing of the facemask to result in the highest satisfaction according to patients.

Hypertrophic Scar Severity at Autograft Sites Is Associated With Increased Pain and Itch After Major Thermal Burn Injury.

Approximately three quarters of major thermal burn injury (MThBI) survivors suffer from hypertrophic scarring (HTS) and over half experience chronic pain or itch. In survivors of MThBI, HTS and chronic pain or itch are considered one of the greatest unmet challenges of postburn injury care and psychosocial reintegration. Although scarring, itch, and pain have been clinically associated, there are no prospective, multisite studies examining tissue autograft site pain or itch and scar outcomes. The authors collected a representative cohort (n = 56) of MThBI survivors who received autografting within 14 days of injury and evaluated graft-site pain or itch severity (0-10 Numeric Rating Scale) and HTS using a validated scar photograph assessment scale 6 months following MThBI. Given that stress is known to influence wound healing, the authors also assessed the relationship between previous trauma exposure, peritraumatic stress, preburn overall health (SF-12), scarring, and chronic pain or itch severity using Spearman's correlation. Association between HTS and chronic pain or itch was significant in a linear regression model adjusted for age, sex, and ethnicity (ß = 0.2, P = .033 for pain, ß = 0.2, P = .019 for itch). Results indicate that prior trauma exposure is inversely correlated (r = -.363, P = .030) with scar severity, but not pain or itch severity 6 months after MThBI. Study results suggest that preburn chronic pain or itch is associated with pathological scarring 6 months following MThBI. Results also indicate that stress may improve scarring after MThBI. Further work to understand the mechanisms that underlie both HTS and chronic pain or itch and their relationship to chronic stress is critical to the development of novel therapies to assist burn survivors recover.

Scar Management Following Burn Injury.

At the 2016 State of the Science meeting, clinicians and burn survivors met to discuss the advances in scar prevention, evaluation and treatment. While emerging evidence exists to support pressure garment treatment of scars and the use of silicone gel, further research is necessary to better delineate indications duration and efficacy of established therapies and to develop and test badly needed new treatments. More accurate and objective assessment of burn depth would assist in the prevention and identification of wounds requiring customized surgery. Laser treatment of scar while rapidly gaining popularity, still lacks high quality evidence as to its efficacy. The psychological impact of burn scars on the recovering patient is poorly appreciated and increased interaction with our patients is needed to more fully understand and address the impact on health related quality of life of their burn scars.

Prevalence of scars and "mini-scars", and their impact on quality of life in Japanese patients with acne.

There have been very few studies on the prevalence and severity of acne scars in Japanese patients. The aim of the present study was to investigate the prevalence of acne scars and their impact on the quality of life (QOL) in Japanese acne patients. Acne scars were classified as mini-scars (atrophic scars of ≥0.5 and <2 mm in diameter) atrophic scars (≥2 mm in diameter), and hypertrophic scars. The severity of acne and acne scars were evaluated. The background of patients and their QOL in relation to acne were assessed. Of 240 subjects, 218 (90.8%) had scars. All patients with scars had mini-scars; 61.2% and 14.2% of 240 had atrophic scars and hypertrophic scars, respectively. Severe scarring was found in patients who had experienced severe acne symptoms, although 15.0% of patients with scars had experienced only mild acne symptoms. The total Dermatology Life Quality Index score was significantly higher in patients with scars than in patients without scars (5.9 ± 4.4 vs 4.2 ± 4.1). Almost all the patients had small atrophic scars with a diameter of 0.5 or more and less than 2 mm, which we have termed "mini-scars". Acne scars had a negative impact on patient QOL. Early initiation of treatment is recommended to avoid acne scars.

The dermatology life quality index as a means to assess life quality in patients with different scar types.

BACKGROUND: Measuring quality of life through questionnaires is a common method to evaluate the impact of different afflictions on the patient's well-being, especially in the field of dermatology where appearance changing afflictions are common. OBJECTIVES: A variety of questionnaires has been used to distinguish different skin conditions like psoriasis, atopic dermatitis and scars. Using the Dermatology Life Quality Index (DLQI), we investigated different scar types regarding their impact on quality of life. METHODS: We assessed the quality of life in 130 patients presenting to our outpatient scar clinic for the first time using the DLQI. Scars were analysed according to their clinical appearance (physiological scars, keloids, hypertrophic scars, atrophic scars, self-harm scars). Physiological scars were established as a baseline for further comparison between groups. RESULTS: Patients in the physiological scar group scored a mean DLQI score of 2.07 ± 3.56, patients in the keloid-, hypertrophic scar-, atrophic scar- and self-harm scar group scored values of 6.06 ± 4.00, 2.53 ± 2.48, 7.26 ± 6.72 and 12.00 ± 3.85 respectively. When compared to the baseline group the difference in the overall score for keloids was +3.99 (P < 0.001), hypertrophic scars scored +0.45 (ns), atrophic scars +5.19 (P < 0.01) and self-harm scars +9.93 (P < 0.001). CONCLUSION: Using the DLQI, we could demonstrate that different subsets of pathological scars do affect patients in a different magnitude. The DLQI provides a promising adjunct for quantifying the quality of life in patients suffering from keloids, atrophic- and self-harm scars and may constitute an interesting additional tool for monitoring the progress of scar treatments.

Physical and psychiatric recovery from burns.

Burn injuries pose complex biopsychosocial challenges to recovery and improved comprehensive care. The physical and emotional sequelae of burns differ, depending on burn severity, individual resilience, and stage of development when they occur. Most burn survivors are resilient and recover, whereas some are more vulnerable and have complicated outcomes. Physical rehabilitation is affected by orthopedic, neurologic, and metabolic complications and disabilities. Psychiatric recovery is affected by pain, mental disorders, substance abuse, and burn stigmatization. Individual resilience, social supports, and educational or occupational achievements affect outcomes.

Risk factors for hypertrophic surgical scar development after thyroidectomy.

Postoperative neck scarring is a major concern for patients who undergo thyroid surgery; however, the treatments for hypertrophic scars are generally considered by patients to provide unsatisfactory outcomes. Therefore, risk factors should be identified and prevention of these factors is considered to be critical in management. We reviewed the medical records of 96 thyroidectomy patients who were divided into two groups based on scar type: patients with hypertrophic (n = 61) and linear flat scars (n = 35). Multivariable logistic regression model was developed to identify risk factors for developing hypertrophic scar. There was no significant difference between the two groups in terms of age, gender ratio, tumor type, and type of operation. Multivariable analysis showed that hypertrophic scar development was associated with scars located within 1 cm above the sternal notch (odds ratio [OR] = 5.94, p = 0.01), prominent sternocleidomastoid muscles (OR = 12.03, p < 0.01), and a high body mass index (OR = 1.33, p = 0.01). The area under the receiver operating characteristic curve for risk factors was 0.85. Development of hypertrophic scar after thyroidectomy was found to be associated with specific preoperative factors such as incision site near the sternal notch, prominent sternocleidomastoid muscles, and high body mass index.

Epidemiology and impact of scarring after burn injury: a systematic review of the literature.

The purpose of this study was to perform a systematic review of the existing literature on the incidence of hypertrophic scarring and the psychosocial impact of burn scars. In a comprehensive literature review, the authors identified 48 articles published since 1965 and written in English which reported the incidence and risk factors for hypertrophic scarring or assessed outcomes related to scarring. Most studies had important methodological limitations limiting the generalizability of the findings. In particular, the absence of standardized valid measures of scarring and other outcome variables was a major barrier to drawing strong conclusions. Among studies on hypertrophic scarring, the prevalence rate varied between 32 and 72%. Identified risk factors included dark skin, female gender, young age, burn site on neck and upper limb, multiple surgical procedures, meshed skin graph, time to healing, and burn severity. With regard to psychosocial outcomes, two studies compared pediatric burn survivors with a nonburn comparison group on a body image measure; neither study found differences between groups. Across studies, burn severity and location had a modest relationship with psychosocial outcome variables. Psychosocial variables such as social comfort and perceived stigmatization were more highly associated with body image than burn characteristics. To advance our knowledge of the epidemiology of scars and the burden of scars, future studies need to implement more rigorous methodologies. In particular, standardized valid measures of scarring and other outcomes should be developed. This process could be facilitated by an international collaboration among burn centers.

Quality of life of patients with keloid and hypertrophic scarring.

Keloid and hypertrophic scarring represent chronic disfiguring dermatoses with a high resistance to therapy. The aim of our study was to assess for the first time the quality of life of patients with hypertrophic scars and keloids, because they suffer from quality of life impairment as much as patients with other chronic skin diseases. An item-pool was created modifying and supplementing the items of the Questionnaire on Experience with Skin Complaints. This questionnaire was distributed to 100 outpatients with keloids and hypertrophic scars. A factor analysis was used to identify the underlying dimensions. Two scales (psychological and physical impairment) of the questionnaire with nine and five items, respectively, were established. Test-retest reliability of the questionnaire was excellent (corr > 0.9). Good validity was suggested by the correlation of physical impairment with pain (P < or = 0.001), pruritus (P < 0.001), and the amount of restriction of mobility (P < 0.001). The psychological scale was associated with pain and restriction of mobility, although the correlations were lower. This study demonstrates for the first time an impairment of quality of life in a large group of patients with keloid and hypertrophic scarring.

Treating hypertrophic scars for 12 or 24 hours with a self-adhesive hydroactive polyurethane dressing.

Treatment with a self-adhesive hydroactive polyurethane dressing (Cutinova thin, Beiersdorf AG, Hamburg, Germany) applied over a period of eight weeks has been shown to have a beneficial effect on hypertrophic scars. However, the use of such dressings during the daytime on visible parts of the body is often problematic and might lead to reduced compliance. In the present study the effect of 12-hour (overnight) treatment was compared with the results of a 24-hour treatment regimen with the same dressing. The dressings were applied over an eight-week period. Evaluation of the hypertrophic scars was by clinical assessment and measurement of colour difference to normal skin, elevation and elasticity. In addition, the patients assessed the treatment effects (questionnaire) and photographs were taken. Under both regimens an improvement in the scar colour (redness) and visual assessment scores took place. The patients also gave a positive assessment of the effects of the treatment. After eight weeks there were no relevant differences between the scars treated with the self-adhesive dressings for 12 hours (overnight) and those treated for 24 hours per day.
