ABSTRACT
Objective: To analyze the clinical characteristics of scar cancer ulcer wound of head and face, and to investigate its diagnosis and treatment. Methods: The clinical data of 14 patients with head and facial scar cancer ulcer wounds who met the selection criteria and admitted between January 2021 and March 2022 were retrospectively analyzed. There were 8 males and 6 females. The age of onset ranged from 21 to 81 years with an average age of 61.6 years. The incubation period ranged from 1 month to 70 years, with a median of 4 years. Site of the disease included 7 cases of head, 6 cases of maxillofacial region, and 1 case of neck region. Injury factors included trauma in 5 cases, scratch in 5 cases, scalding in 2 cases, burn in 1 case, and needle puncture in 1 case. Pathological results showed squamous cell carcinoma in 9 cases, basal cell carcinoma in 3 cases, sebaceous adenocarcinoma in 1 case, papillary sweat duct cystadenoma combined with tubular apocrine sweat gland adenoma in 1 case. There was 1 case of simple extensive tumor resection, 1 case of extensive tumor resection and skin grafting repair, 7 cases of extensive tumor resection and local flap repair, and 5 cases of extensive tumor resection and free flap repair. Results: All the 14 patients were followed up 16-33 months (mean, 27.8 months). Two patients (14.29%) had scar cancer ulcer wound recurrence, of which 1 patient recurred at 2 years after 2 courses of postoperative chemotherapy, and was still alive after oral traditional Chinese medicine treatment. One patient relapsed at 1 year after operation and died after 2 courses of chemotherapy. One patient underwent extensive resection of the left eye and periocular tumor and the transfer and repair of the chimaeric muscle axial flap with the perforating branch of the descending branch of the left lateral circumflex femoral artery, but the incision healing was poor after operation, and healed well after anti-infection and debridement suture. The wounds of other patients with scar cancer ulcer did not recur, and the wounds healed well. Conclusion: Scar cancer ulcer wound of the head and face is common in the middle-aged and elderly male, and the main pathological type is squamous cell carcinoma. Local extensive resection, skin grafting, or flap transfer repair are the main treatment methods. Early active treatment of wounds after various injuries to avoid scar repeated rupture and infection is the foundamental prevention of scar cancer.

Cutaneous burn scars impact various aspects of life. Scar treatment is mainly evaluated on scar characteristics. Consensus is needed on which other outcomes to capture, ensuring they are relevant to patients, clinicians, and researchers. The aim of this study was to identify, discuss and analyze outcomes related to cutaneous burn scarring, incorporating the voice of patients and views of healthcare professionals. For this, a Delphi process consisting of two survey rounds and a consensus meeting was initiated. Burn scar-related outcomes were identified from an existing comprehensive list of 100 outcomes by an international panel of patients, healthcare professionals and researchers. Fifty-nine outcomes were identified from the Delphi process as related to scarring (≥60% votes). Outcomes less impactful in relation to scar outcomes included psychosocial issues, sense of normality, understanding of treatment, costs and systemic issues. To represent a holistic assessment of outcomes related to cutaneous burn scarring, this Delphi process established a battery of outcomes currently included in scar quality assessment tools, and an expanded set of less frequently considered outcomes. Future work in this area must include the patient voice from developing countries. This is essential to identify globally applicable outcomes related to scarring.

OBJECTIVE: We aimed to investigate the safety and efficacy of laser or intense pulsed light therapy for early treatment of surgical scar. METHODS: A literature search was conducted for relevant prospective, randomized controlled trials published in PubMed, Embase, Web of Science, Cochrane Library, CNKI, WanFang Database, and VTTMS between January 2006 and January 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was used to extract literature data. The risk of bias was assessed by RevMan. Safety was assessed based on the presence of serious adverse reactions (blisters, infections, burns above the second degree), while effectiveness was assessed using the Vancouver Score Scale. RESULTS: 1512 related articles were preliminarily retrieved, including 1211 English articles and 301 Chinese articles. According to the inclusion criteria and exclusion criteria, 12 articles were selected for this analysis. In total, 475 patients were included (laser group, 238; control group, 236). All studies confirmed that the laser group was superior to the control group. In the subgroup analysis of 7 articles, the standardized mean difference was 1.99 (P = 0.0001). CONCLUSIONS: This meta-analysis demonstrates that laser or intense pulsed light therapy is a safe and effective approach for early surgical scar treatment, resulting in improved scar appearance and minimal adverse reactions. LEVEL OF EVIDENCE I: This journal requires that authors assign a level of evidence to each article.

Pressure-induced alopecias (PAs) are an infrequent group of scarring and nonscarring alopecias that occur after ischemic obstruction of capillaries that leads to circumscribed areas of hair loss. Initially described after prolonged surgeries or immobilization, type 1 PA occurs after sustained external pressure to the skin, mainly the scalp prominences. Alopecia induced by cosmetic procedures, referred in this review as type 2 PA, is reported with increased frequency in literature and predominantly emerges from pressure exerted by the volume of injectables. It is important to differentiate type 2 PA from vascular occlusion-induced alopecia because they represent distinct entities. Clinically, PA may present with erythema, swelling, and tenderness; however, alopecia might be the sole manifestation. Crusts and ulceration are associated with a worse outcome and a higher risk of scarring alopecia. Prompt diagnosis is paramount to prevent complications. Trichoscopy, although considered nonspecific, may provide relevant clues for an accurate diagnosis. Hair regrows in most cases, but prognosis depends on ischemia severity and timely treatment with reperfusion therapies or mobilization. Treatment of hair loss is usually not necessary because the disease in most cases is self-limited and reversible. The role of topical minoxidil and corticosteroids remains unknown.

Objective: To compare the efficacy and safety of 2 940 nm fractional erbium laser combined with fractional micro-plasma radiofrequency (FMR) therapy and 2 940 nm fractional erbium laser in the treatment of atrophic acne scars. Methods: A prospective randomized controlled research was conducted. A total of 100 atrophic acne scar patients (38 males and 62 females, aged 18-37 years) who were treated in the Scar Laser Clinic of the Department of Plastic and Reconstructive Surgery of Shanghai Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine from March 2018 to March 2021 and conformed to the inclusion criteria were recruited. The patients were randomly divided into erbium laser+FMR group and erbium laser alone group, with 50 cases in each group. The facial acne scars of patients in erbium laser alone group were treated with 2 940 nm fractional erbium laser, while the facial acne scars of patients in erbium laser+FMR group were treated with erbium laser as above, besides, the scars of U and M types were treated with FMR, once every 3 months for a total of 3 times. Before the first treatment and 3 months after each treatment, the Echelle D'Assessment Clinique des Cicatrices D'Acne (ECCA) was used to score the scar. The occurrence of adverse reaction during the treatment process was observed and recorded, and the incidence was calculated. Three months after the last treatment, the 5-level classification method was used to evaluate the satisfaction of patients with the treatment effect, and the satisfaction rate was calculated. Data were statistically analyzed with independent sample t test and chi-square test. Results: A total of 89 patients completed the study, including 46 patients in erbium laser+FMR group (19 males and 27 females, aged (26±5) years) and 43 patients in erbium laser alone group (15 males and 28 females, aged (27±6) years). The ECCA scores before the first treatment and 3 months after the first treatment of patients were similar between the two groups (P>0.05). The ECCA scores of patients in erbium laser+FMR group at 3 months after the second and third treatment were 72±23 and 61±18, respectively, which were significantly lower than 85±26 and 76±25 in erbium laser alone group (with t values of -2.45 and -3.26, respectively, P<0.05). During the treatment process, the incidence of adverse reaction of patients in erbium laser+FMR group and erbium laser alone group were 23.91% (11/46) and 16.28% (7/43), respectively, and there was no statistically significant difference between the two groups (P>0.05). The satisfaction rate of patients in erbium laser+FMR group was 78.26% (36/46) at 3 months after the last treatment, which was significantly higher than 53.49% (23/43) in erbium laser alone group (χ2=6.10, P<0.05). Conclusions: The 2 940 nm fractional erbium laser combined with FMR is superior to 2 940 nm fractional erbium laser alone in the treatment of facial atrophic acne scars, achieving significantly higher efficacy without significantly increasing the incidence of adverse reaction, and patients are more satisfied with the efficacy. It can be used as a recommended therapy in clinical practice.

Objective: To investigate the clinical efficacy of local injection of platelet-rich plasma (PRP) combined with double-layer artificial dermis in treating wounds with exposed tendon on extremity. Methods: A retrospective observational study was conducted. From December 2017 to October 2022, 16 patients were admitted to Department of Orthopaedic Trauma of the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine, and 32 patients were admitted to Department of Burns and Plastic Surgery of Guiyang Steel Factory Staff Hospital. All the patients had wounds with exposed tendon on extremity caused by various reasons and met the inclusion criteria. There were 39 males and 9 females, aged 26 to 58 years. The patients were divided into PRP alone group, artificial dermis alone group, and PRP+artificial dermis group, with 16 patients in each group. The wounds were treated with autologous PRP, double-layer artificial dermis, or thei combination of autologous PRP and double-layer artificial dermis, followed by autologous split-thickness scalp grafting after good growth of granulation tissue. On the 7th day after the secondary surgery, the autograft survival was observed, and the survival rate was calculated. The wound healing time and length of hospital stay of patients were recorded. At 3 and 6 months after wound healing, the Vancouver scar scale (VSS) was used to score the pigmentation, height, vascularity, and pliability of scars, and the total score was calculated. Adverse reactions during the entire treatment process were recorded. Data were statistically analyzed with chi-square test, Fisher's exact probability test, one-way analysis of variance, least significant difference test, Kruskal-Wallis H test, Nemenyi test, and Bonferroni correction. Results: On the 7th day after the secondary surgery, there was no statistically significant difference in the autograft survival rate of patients among PRP alone group, artificial dermis alone group, and PRP+artificial dermis group (P>0.05). The wound healing time and length of hospital stay of patients in PRP+artificial dermis group were (20.1±3.0) and (24±4) d, respectively, which were significantly shorter than (24.4±5.5) and (30±8) d in PRP alone group (P<0.05) and (24.8±4.9) and (32±8) d in artificial dermis alone group (P<0.05). At 3 and 6 months after wound healing, the pliability scores of patients in PRP+artificial dermis group were significantly lower than those in PRP alone group (with Z values of 12.91 and 15.69, respectively, P<0.05) and artificial dermis alone group (with Z values of 12.50 and 12.91, respectively, P<0.05). There were no statistically significant differences in pigmentation, vascularity, height scores, and total score of scar of patients among the three groups (P>0.05). In artificial dermis alone group, one patient experienced partial liquefaction and detachment of the double-layer artificial dermis due to local infection of Staphylococcus epidermidis, which received wound dressing change, second artificial dermis transplantation, and subsequent treatment as before. No adverse reactions occurred in the remaining patients during the whole treatment process. Conclusions: Local injection of PRP combined with double-layer artificial dermis is effective in treating wounds with exposed tendon on extremity, which can not only significantly shorten wound healing time and length of hospital stay, but also improve scar pliability after wound healing to some extent in the long term. It is a clinically valuable treatment technique that is worth promoting and applying.

Spinal cord injury (SCI) is a commonly occurring and severe form of central nervous system (CNS) injury. Previous studies have demonstrated that electroacupuncture (EA) therapy promotes recovery from SCI. In this study, we observed changes in the glial scars of rats with SCI to gain insight into how EA therapy positively influences locomotor function. The experimental rats were randomly divided into three groups: the sham group, the SCI group and the SCI + EA group. Rats in the SCI + EA group received a 28-day treatment course using the Dazhui (GV14) acupoint and the Mingmen (GV4) acupoint for 20 min/day. The Basso-Beattie-Bresnahan (BBB) score was used to estimate the neural function of rats in all groups. We found that before sacrifice on Day 28, the BBB score was significantly improved in the SCI + EA group, which was higher than that observed in the SCI group. Hematoxylin-eosin staining revealed morphological improvements in spinal cord tissues of the rats in the EA + SCI group with reduced glial scars and cavities. Based on immunofluorescence staining, reactive astrocytes overpopulated both the SCI and SCI + EA groups following SCI. Moreover, improved generation of reactive astrocytes at lesions was observed in the SCI + EA group compared with the SCI group. After treatment, EA inhibited glial scar generation. EA effectively downregulated fibrillary acidic protein (GFAP) and vimentin protein and mRNA expression levels, according to the results from Western blot assays and reverse transcription-polymerase chain reaction (RT-PCR). We hypothesized that these findings described might represent the mechanism underlying EA inhibition of glial scar generation, morphological improvements in tissues and promotion of neural recovery from SCI in rats.

BACKGROUND: The skin is a protective barrier of the body against external factors, and its damage leads to a loss of integrity. Normal wound healing results in a correct, flat, bright, and flexible scar. Initial skin damage and patient specific factors in wound healing contribute that many of these scars may progress into widespread or pathologic hypertrophic and keloid scars. The changes in cosmetic appearance, continuing pain, and loss of movement due to contracture or adhesion and persistent pruritis can significantly affect an individual's quality of life and psychological recovery post injury. Many different treatment methods can reduce the trauma and surgical scars. Manual scar treatment includes various techniques of therapy. The most effectiveness is a combined therapy, which has a multidirectional impact. Clinical observations show an effectiveness of manual scar therapy. MATERIAL AND METHODS: The aim of this work was to evaluate effectiveness of the scar manual therapy combined with complementary methods on the postoperative scars. Treatment protocol included two therapies during 30 min per week for 8 weeks. Therapy included manual scar manipulation, massage, cupping, dry needling, and taping. RESULTS: Treatment had a significant positive effect to influence pain, pigmentation, pliability, pruritus, surface area, and scar stiffness. Improvement of skin parameters (scar elasticity, thickness, regularity, color) was also noticed. CONCLUSION: To investigate the most effective manual therapy strategy, further studies are needed, evaluating comparisons of different individual and combined scar therapy modalities.

Striae alba, as an unsettling skin complication, has the potential to threaten the physical appearance and psychological health of individuals. So far, dermatologists' endeavors have been futile in finding an ideal treatment. This study evaluated microneedling as a novel treatment modality for striae alba scars. Microneedling was implemented in 1-3 sessions in 2-week intervals among patients with striae alba lesions. The lesions were photographed before and 3 months after the treatment, while all side effects were recorded. Two non-involved dermatologists and a patient self-report based on a visual analog score scale were utilized to evaluate the clinical improvement of striae scars. The complication rate among the 32 patients was 25%, which consisted of seven (21.9%) cases of post-inflammatory hyperpigmentation and one case (3.1%) of skin infection. The average improvement score among the patients in our study based on their self-report was 5.3 ± 1.3. (Range 4-8), while based on physician evaluation was 5.6 ± 1.2 (range 3.5-8). There was a significant association between lower age and higher self-report scores. Also, the improvement of lesions was more significant in skin type 3 compared to 2, based on physician assessment. In this study, MN was effective in ameliorating SA scars and was observed to induce better clinical satisfaction in younger patients and breast lesions. The studies concerning the use of MN in treating SA have yielded much attention lately, and they have denoted the relatively low cost of MN, its capability to be utilized over vast treatment areas, and its safety in that regard. Further research regarding the comparison of MN's efficacy in solo use versus implementing it as an adjuvant modality should be carried out.

Objective: To explore the clinical effects of fractional carbon dioxide laser combined with minimally invasive scar release in the treatment of post-acne atrophic scars. Methods: A retrospectively observational study was conducted. From January to June 2021, 60 patients with grade 3 and 4 post-acne atrophic scars who met the inclusion criteria were admitted to the First Affiliated Hospital of Henan University of Traditional Chinese Medicine. According to the adopted treatment methods, 30 patients treated with fractional carbon dioxide laser combined with minimally invasive scar release were included in combined treatment group (19 males and 11 females, aged (26±4) years), and 30 patients treated with fractional carbon dioxide laser alone were included in laser alone group (18 males and 12 females, aged (25±6) years). All the patients received the treatment once every two months, totally 3 times. Before the first treatment and 2 months after the last treatment, the scars were assessed by échelle d'évaluation clinique des cicatrices d'acné (ECCA). In 2 months after the last treatment, the curative effect was evaluated and the total effective rate was calculated according to the ECCA score. The adverse reactions of patients during the treatment were recorded. Data were statistically analyzed with independent sample t test, Wilcoxon rank-sum test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. Results: Before the first treatment, the ECCA scores of patients in the two groups were similar (P>0.05). In 2 months after the last treatment, the ECCA scores of patients in combined treatment group were significantly lower than those of laser alone group (Z=-2.89, P<0.05). The ECCA scores of patients in combined treatment group and laser alone group in 2 months after the last treatment were both significantly lower than those before the first treatment (with Z values of -4.81 and -4.79, respectively, P<0.05). In 2 months after the last treatment, the treatment in laser alone group cured the scars in 2 patients, and were markedly effective in 13 patients, effective in 7 patients, and ineffective in 8 patients; the treatment in combined treatment group cured the scars in 4 patients, and were markedly effective in 22 patients, effective in 3 patients, and ineffective in one patients. The total effective rate of scar treatment in combined treatment group (96.67%, 29/30) was significantly higher than 73.33% (22/30) in laser alone group (P<0.05). During treatment, in combined treatment group, 3 patients had pain, one patient had redness and swelling, and one patient had pigmentation. In laser alone group, one patient had pain, and 2 patients had pigmentation. No infection occurred in the wounds of all the patients in the two groups. Conclusions: Compared with fractional carbon dioxide laser alone, fractional carbon dioxide laser combined with minimally invasive scar release for post-acne atrophic scars can result in a higher total effective rate, with simple operation and good effect, so it is worthy of clinical application.

BACKGROUND: Hyperbaric oxygen (HBO) therapy involves breathing pure oxygen or a high oxygen concentration above atmospheric (ATM) pressure in an enclosed chamber. Studies on pathological scars have demonstrated that HBO can inhibit the formation of pathological scars. OBJECTIVE: To evaluate the efficacy of HBO in the treatment of pathological scars via meta-analysis. METHODS: Searches were run on various databases, including the Cochrane, Embase, PubMed, Web of Science, and CNKI databases. A comparative study was conducted on patients with pathological scars treated with or without HBO. We used RevMan 5.4 software to determine the recurrence rate, treatment satisfaction, and Vancouver Scar Scale(VSS) score in the pathological scar. RESULTS: A total of 543 publications were identified; after screening, four were selected for review, including one randomized controlled trial (RCT), one controlled clinical trial (CCT), and two retrospective cohort studies. Meta-analysis results showed that HBO treatment reduced the pathological scar recurrence rate after surgery and radiotherapy (OR = 0.26, 95% CI: 0.13-0.52, p = 0.0001). Patients had higher satisfaction after HBO therapy (OR = 4.45, 95% CI: 1.49-13.30, p = 0.007). The Vancouver scar scale (VSS) score of patients with pathological scars was significantly improved in the HBO group (SMD: -3.82, 95% CI: -6.07to -0.49, p = 0.02). CONCLUSIONS: HBO treatment decreased the recurrence rate of pathological scars after surgery and radiotherapy, increased patient satisfaction, and reduced the VSS score, thus providing a new way to treat pathological scar hyperplasia. However, evaluation of the longer-term effects of HBO treatment requires further comprehensive studies, including more RCTs.

AIMS: Anti-tachycardia pacing (ATP) is a reliable electrotherapy to painlessly terminate ventricular tachycardia (VT). However, ATP is often ineffective, particularly for fast VTs. The efficacy may be enhanced by optimized delivery closer to the re-entrant circuit driving the VT. This study aims to compare ATP efficacy for different delivery locations with respect to the re-entrant circuit, and further optimize ATP by minimizing failure through re-initiation. METHODS AND RESULTS: Seventy-three sustained VTs were induced in a cohort of seven infarcted porcine ventricular computational models, largely dominated by a single re-entrant pathway. The efficacy of burst ATP delivered from three locations proximal to the re-entrant circuit (septum) and three distal locations (lateral/posterior left ventricle) was compared. Re-initiation episodes were used to develop an algorithm utilizing correlations between successive sensed electrogram morphologies to automatically truncate ATP pulse delivery. Anti-tachycardia pacing was more efficacious at terminating slow compared with fast VTs (65 vs. 46%, P = 0.000039). A separate analysis of slow VTs showed that the efficacy was significantly higher when delivered from distal compared with proximal locations (distal 72%, proximal 59%), being reversed for fast VTs (distal 41%, proximal 51%). Application of our early termination detection algorithm (ETDA) accurately detected VT termination in 79% of re-initiated cases, improving the overall efficacy for proximal delivery with delivery inside the critical isthmus (CI) itself being overall most effective. CONCLUSION: Anti-tachycardia pacing delivery proximal to the re-entrant circuit is more effective at terminating fast VTs, but less so slow VTs, due to frequent re-initiation. Attenuating re-initiation, through ETDA, increases the efficacy of delivery within the CI for all VTs.

Objectives: Our study aimed to investigate the clinical features, management, and maternal-infant prognosis in patients with complete uterine rupture in the second and third trimester of pregnancy. Methods: A total of 15 patients with complete uterine rupture in their second and third trimester of pregnancy who were admitted to our hospital between January 2012 and December 2020 were included in our study. The patients enrolled were divided into the scar group (11 patients) and the non-scar group (4 patients) according to the existence or absence of a uterine scar. The general data, clinical characteristics and follow-up results in the 2 groups were compared. Results: There was no significant difference in age, pregnancy duration or delivery cycle between the 2 groups (P > .05). The incidence of original scar rupture in the scar group was significantly higher than in the non-scar group (P > .05). No significant difference was found in clinical characteristics between the scar and the non-scar groups (P > .05). The most common clinical features included abdominal pain, inability to lie flat, hemorrhagic shock, prenatal vaginal bleeding and uterine rupture, mostly occurring in the lower segments of the uterus and cervix. A total of 3 patients were misdiagnosed as having surgical disease. After completing relevant examinations, the uterine rupture was repaired surgically; the patients were discharged after blood transfusion, and their condition resolved. In all, 3 patients in the non-scar group and 1 patient in the scar group were transferred to the intensive care unit (ICU). All 15 patients were discharged after treatment. Follow-up was completed by all patients for 12 to 36 months, with an average follow-up time of 23.09 ± 2.19 months. Of the 15 patients, 2 underwent induced abortion after 24 months due to unplanned pregnancy. A 5-minute Apgar score of ≤7 in the scar group was higher than that in the non-scar group, but the difference was not statistically significant (P > .05). Perinatal mortality in the 15 patients was 40.00% (6/15). Conclusion: The most common clinical features in patients with complete uterine rupture in the second and third trimester of pregnancy included abdominal pain, inability to lie flat, hemorrhagic shock, prenatal vaginal bleeding and uterine rupture, mostly occurring in the lower segments of the uterus and cervix. In addition, a remarkably worse maternal-infant prognosis was seen in patients with complete uterine rupture in the second and third trimester of scarless pregnancy compared with patients with complete uterine rupture in the second and third trimester of scarred pregnancy.

Burn scar contracture greatly limits function for burn survivors, particularly when the scarring crosses multiple joints. Previous research has identified fields of skin recruited during single joint motion, called cutaneous functional units (CFU), indicating that impairments may be seen distal to the injured tissue. This case report connects the principles of CFU and yoga-inspired therapy modalities in improving clinical outcomes for a burn survivor. The patient is a 38-year-old male who sustained deep partial-thickness electrical burns to his neck, chest, and bilateral upper extremities, presenting with significantly decreased range of motion. The patient attended physical therapy 4 days a week, where he performed a specific yoga asana program during each session. Outcomes including standard range of motion measures, the Vancouver Scar Scale (VSS), and the Neck Disability Index (NDI), which were recorded every 10 sessions. CFUs of cervical extension and shoulder flexion were analyzed via photographs comparing cutaneous position during specified yoga poses and resting anatomical position in standing. Over 30 visits, cervical and shoulder range of motion increased, although the VSS and NDI did not show significant improvement. Yoga poses showed overall cutaneous recruitment distal to the targeted joints, and burned skin was recruited similarly to nonburned skin in positions of stretch. Incorporating multijoint approaches for stretching, like yoga, appears to contribute to improved clinical range-of-motion outcomes when paired with traditional burn-rehabilitation interventions. Yoga poses involving multiple joints align with the principle of CFUs, warranting continued investigation.

BACKGROUND: Scar massage is a widely used treatment modality in hand therapy. This intervention is thoroughly discussed in the literature relating to burns rehabilitation, however, the evidence for its use in treating linear scars following surgery is limited. PURPOSE OF STUDY: To collate the empirical literature on scar massage for the treatment of postsurgical cutaneous scars. STUDY DESIGN: Scoping review. METHODS: Medline, EMBASE, CINAHL, AMED, Scopus, ProQuest Dissertations & Theses Global, and the Joanna Briggs Institute were searched from inception to December 2020. Two researchers used a data extraction tool to record key demographic, intervention and outcome data, and to apply the Oxford Levels of Evidence for each study. RESULTS: Twenty-five studies met the inclusion criteria, reporting on a combined sample of 1515 participants. Only two papers addressed hand or wrist scars (92 participants). While all studies reported favorable outcomes for scar massage, there were 45 different outcome measures used and a propensity towards non-standardized assessment. Intervention protocols varied from a single session to three treatments daily for 6 months. The results from 13 studies were confounded by the implementation of additional rehabilitation interventions. CONCLUSIONS: The overall findings suggest that while there may be benefits to scar massage in reducing pain, increasing movement and improving scar characteristics; there is a lack of consistent research methods, intervention protocols and outcome measures. This scoping review highlights the heterogenous nature of research into scar massage following surgery and supports the need for further research to substantiate its use in the clinical setting.
