Improvement of 1-Stage Comprehensive Operation Technique for Blepharophimosis-Ptosis-Epicanthus Inversus Syndrome.

This retrospective case series presents the clinical results of a modified 1-stage comprehensive surgical method for blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). A total of 25 patients with BPES underwent a modified reverse Z-plastic surgery method to bisect the epicanthus into 2 unequal V-shaped flaps and suture them alternately. The medial canthus ligament was partially incised, shortened, and sutured; the outer canthus was opened with a V-Y flap. The gray line of the outer canthus was cut to extend the eyelid margin length. Ptosis was corrected using the orbicularis oculi-frontalis composite flap technique. We studied the inner intercanthal distance (IICD), interpupillary distance (IPD), horizontal palpebral fissure length (HPFL), marginal reflex distance 1 (MRD-1), IICD/IPD ratio, IICD/HPFL ratio, Vancouver Scar Scale, and overall postoperative satisfaction. The 25 patients included 12 girls and 13 boys (mean age, 8.3 ± 6.8 years), 19 of whom had a family history of BPES. The mean IPD value was 50.15 ± 7.43 mm. IICD decreased from 39.38 ± 2.39 mm preoperatively to 31.64 ± 2.37 mm postoperatively, IICD/IPD from 0.8 ± 0.1 preoperatively to 0.6 ± 0.1 postoperatively ( P < 0.05), and IICD/HPFL from 1.98 ± 0.33 preoperatively to 1.22 ± 0.10 postoperatively ( P < 0.01). HPFL increased from 20.08 ± 3.53 mm preoperatively to 26.04 ± 1.36 mm postoperatively ( P < 0.01), and MRD-1 from -1.12 ± 0.71 mm preoperatively to 3.24 ± 0.47 mm postoperatively ( P < 0.01). The postoperative Vancouver Scar Scale score was 3.68 ± 1.07. Patient satisfaction was rated as 8.8 ± 1.08, with a relatively high overall satisfaction rate. The corrective effect on BPES was noticeable, improving the IICD/HPFL and IICD/IPD ratios. Postoperative scars were not evident, and patient satisfaction was high. Therapeutic, IV.

Clinical Effects of Pulsed Dye Laser Dynamically Combined with Triamcinolone Acetonide in the Treatment of Postoperative Recurrence Keloids.

This study aimed to explore the clinical effects of pulsed dye laser (PDL) dynamically combined with triamcinolone acetonide (TAC) in the treatment of post-operative keloids recurrence. This study retrospectively analysed the clinical data of 29 keloid patients (with 39 keloids) from April 2014 to February 2020. The patients were divided into TAC group (14 patients with 19 keloids) and dynamic treatment group (15 patients with 20 keloids) according to the post-operative treatment that they received. The keloids were assessed by Vancouver scar scale (VSS), patient and observer scar assessment scale (POSAS) and the effect of keloids on the quality of life of patients was evaluated with dermatology life quality index (DLQI) scale before the surgical treatment, at any time of relapse, and 24 months after the surgical treatment. The recurrence-free interval, relative cure time, and the cumulative times of TAC injection when the relative cure could be assessed as achieved, and the incidence of adverse reactions were calculated. Patients experiencing a recurrence within 2 years after surgery included 19 keloids (25.33%) that developed a recurrent event within 6 months, 34 keloids (45.33%) that within 12 months, and 39 keloids (52.00%) that within 24 months after surgery. Anterior chest keloid had the highest recurrence rate and ear keloid had the lowest recurrence rate. The total pigmentation and vascularity (VSS and POSAS) scores of patients' keloids in TAC group and dynamic treatment group 24 months after treatment were significantly lower than those before treatment and at relapse (P < 0.05), the total VSS and POSAS scores were significantly lower at 24 months than before treatment and at relapse (P < 0.05), and the DLQI scale score was significantly lower at 24 months than before treatment (P < 0.05). The VSS and POSAS scores of patients' keloids at 24 months after treatment were significantly lower in the dynamic treatment group than in the TAC group. The relative cure time of patients' keloids in the dynamic treatment group was 6.47 ± 2.72 months, which was significantly shorter than 8.65 ± 3.67 months in the TAC group (P < 0.05). The cumulative number of TAC injections that were given to achieve a relative cure of patients' keloids in dynamic treatment group was 3.60 ± 1.76, which was significantly less than 5.24 ± 2.25 in TAC group. The total incidence of adverse reactions was lower in the dynamic group than in TAC group, but this difference did not reach statistical significance (P > 0.05). Compared with TAC injection alone, PDL dynamically combined with TAC in the treatment of keloid with post-operative recurrence can shorten the relative cure time, reduce the number of TAC injections and improve the clinical efficacy.

Application of 3D transparent facemasks in long-term outpatient rehabilitation of facial scars after burns: a retrospective cohort study of improved appearance of target scars with different healing time.

Severe facial burns may cause scarring problems and affect living quality of patients. With the advent of 3D facemasks, it is being used to treat facial scars; however, its efficacy must be confirmed by adequate studies. A retrospective analysis of 26 patients who visited rehabilitation outpatient clinic from 2017 to 2022. Patients were separated into two groups based on the time to healing (TTH) following burn injury: early healing group (TTH ≤ 21 days) and late healing group (TTH > 21 days). To compare treatment outcomes and differences between the two groups, 3D facemask application was assessed using the Vancouver Scar Scale (VSS), patient satisfaction, and complications. In both groups, there were significant improvements in the total VSS scores (P<0.01) and each VSS subscore (P<0.01). These scar characteristics improved over time as the treatment progressed. Compared with the late healing group, the early healing group had more obvious effects on improving scar pigmentation (P<0.05) and vascularity (P<0.05) at similar assessment time points after burns. At the last assessment, there was a significant difference in total VSS scores between groups (P=0.009). For the early and late healing groups, respectively, the mean gradient value (SE) of the total VSS scores was 1.550 (0.373) and 1.283 (0.224) over the course of the treatment periods. 3D facemasks are effective in the rehabilitation of facial scars caused by burns, which should be used for prevention and treatment in the initial stages of scar development.

DS11 A double-blinded randomized control study to compare the effectiveness and safety of intralesional vitamin D3 with intralesional triamcinolone and its correlation with tissue expression of vitamin D receptors in patients with keloid

Abstract Intralesional steroids are the first line of treatment for keloids, and intralesional vitamin D has shown promise in the management of keloids in a few small studies. The aim was to compare the efficacy and safety of intralesional vitamin D with intralesional triamcinolone and its correlation with tissue expression of vitamin D receptors (VDRs) in the treatment of keloids. Sixty patients were randomly divided into two groups in 1 : 1 ratio. Patients in group A received intralesional vitamin D (200 000 IU, dose 0.2 mL cm−2); those in group B received intralesional triamcinolone acetonide (20 mg mL−1, dose 0.1 mL cm−2). Four monthly injections were given, and the patients were followed-up for a further 24 weeks. The Vancouver Scar Scale (VSS) was used for keloid evaluation. Pre- and post-treatment biopsies of 20 patients from both groups were taken to assess the correlation between the expression of VDR receptor levels before and after treatment. The mean VSS scores of patients in both groups were statistically significantly reduced over the course of the follow-up (P &amp;lt; 0.001). Mean (SD) reduction in VSS at the end of treatment period was 5.17 (0.59) in patients in group A and 4.77 (0.77) in those in group B. The proportion of the patients showing &amp;gt; 50% reduction in VSS score was higher in patients in group B vs. those in group A (77% vs. 50%; P = 0.032). Rates of recurrence were comparable between the two groups (P = 0.51). Hypopigmentation (80% vs. 37%; P &amp;lt; 0.001) and atrophy (73% vs. 40%; P = 0.009) were more common in patients in group B than in those in group A. There was no significant difference in pre- and post-treatment values of tissue VDR expression in either group. Both triamcinolone and vitamin D are effective in the management of keloids. Although the reduction in VSS score was higher with corticosteroids than vitamin D, an intralesional injection of vitamin D had lower incidence of adverse effects such as atrophy and hypopigmentation.

Carbon dioxide laser treatment of burn-related scarring: Results of the ELIPSE (Early Laser Intervention Promotes Scar Evolution) prospective randomized controlled trial

To investigate the impact of ablative fractional carbon dioxide laser (AFCO2L) on patient-reported outcomes measures, subjective scar appearance, dermal architecture, and gene transcription in early burn scars. Fifteen adult patients with a burn-related scar were recruited. Inclusion criteria were two non-contiguous scar areas of 1% total body surface area, similar baseline Vancouver scar scale (VSS) score and 3months since the time of injury. All participants acted as their own control. Scars were randomized to treatment or control. Treatment scars received three AFCO2L treatments at 6-week intervals. Outcome measures were recorded at baseline, 3, 6, and 12-months post-treatment. Measures included blinded VSS, Patient Observer Scar Assessment Scale (POSAS), Brisbane Burn Scar Impact Profile (BBSIP), blinded scar photo assessment, histological tissue analysis, and RNA sequencing analysis. No significant difference was found in VSS, scar erythema, or pigmentation. Patient POSAS improved in scar thickness and texture following AFCO2L. All elements of BBSIP improved in control and laser groups. AFCO2L-treated scars were scored better than control scars by blinded raters. RNA sequencing illustrated that AFCO2L induced sustained changes in fibroblast gene expression. AFCO2L treated scars had significantly altered scar thickness and texture 6 months post-laser and were rated better than controls on blinded photo analysis after 3 treatments. RNASeq results suggest laser treatment alters the transcriptome of treated fibroblasts for at least 3 months after treatment. Expansion of this research to study in more depth fibroblast changes in response to laser, as well as assessing the impact on daily activity and quality of life, will be beneficial.

Effects of mechanical stimulation on mastectomy scars within 2 months of surgery: A single-center, single-blinded, randomized controlled trial.

One common complication after mastectomy is thickened scars at the surgical site that impair shoulder function. This study aimed to investigate the effects of mechanical stimulation on scar appearance, arm function, and quality of life of breast cancer survivors after mastectomy. This was a single-center, single-blinded (assessor), randomized controlled trial with a 3-month follow-up. Women who had undergone mastectomy in the preceding 6 weeks for breast cancer were randomly allocated to an experimental group and a control group by permuted block randomization (block size=6). The experimental group received conventional treatment (mobilization and strengthening exercises) and mechanical stimulation applied to the mastectomy scar twice a week for 6 weeks (12 sessions). The control group received 12 sessions of conventional treatment only. Primary outcome measures included the Vancouver Scar scale (VSS) to assess scar quality. The secondary outcomes were spectrophotometry, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; shoulder range of motion; the Numeric Pain Rating scale; hand grip strength; and Functional Assessment of Chronic Illness Therapy-Breast Cancer (FACT-B). One hundred and eight participants were equally randomized to 2 groups. All follow-up assessments were completed in September 2018. Intention-to-treat analysis revealed a significant group×time interaction on the VSS (η²=0.161, p < 0.001), DASH (η²=0.060, p=0.003), and FACT-B functional well-being scores (η²=0.033, p=0.034), indicating that the experimental group (n=54) showed greater improvement in these outcomes than the control group (n=54). Post-hoc analysis showed that the improvements in the VSS and DASH scores remained apparent at the 3-month follow-up. Other outcomes did not yield significant group×time interaction. No adverse effects were reported. The addition of mechanical stimulation to a conventional intervention program improved scar appearance, arm function, and functional well-being compared with conventional intervention alone.

Serial Casting as an Effective Method for Burn Scar Contracture Rehabilitation: A Case Series.

Guidelines and protocols for orthoses in burn scar contracture rehabilitation are limited. The current study aims to determine the optimal frequency of casting, potentially facilitating the development of a serial casting protocol. Previous literature supporting casting has low generalizability due to methodology limitations. Seven patients with burn scar contracted joints, who did not respond to traditional therapy, were recruited in this study. Patients were serially casted once, three times, or five times a week. Joint range of motion was maximized with stretching and exercise techniques before every new cast application. Across all patients, active range of motion increased from 65.8 ± 27.8° to 108.1 ± 23.3° with casting; or from 57.8 ± 16.2% to 96.7 ± 2.9% of normal. Similarly, scars improved from 9.5 ± 1.5 to 4.9 ± 1.4 on the Modified Vancouver Scar Scale score. This therapeutic effect was achieved within an average of 8.5 ± 3.7 d and 4.0 ± 2.2 new cast applications. Given the study findings, the procedures outlined could be used to develop a standardized serial casting protocol for burn scar contracture rehabilitation.

The Use of Acellular Dermal Matrix for the Closure of Skin Defects

Background &amp; Objectives: Skin substitutes are a diverse set of biologics, synthetics, and biosynthetic materials that can replace open skin wounds temporarily or permanently. Skin substitutes are designed to mimic the qualities of natural skin. One must select an option that accomplishes an excellent wound healing and closure. This study aimed to assess the reliability and effectiveness of ?acellular dermal matrix for potentially more pliable coverage of the wound and for better ?functional and aesthetic appearance of the skin defects. Methods: A prospective cohort study performed on 20 patients with full-thickness skin defects who underwent surgery using acellular dermal substitute and skin grafting in Erbil Governorate from January 2017 to December 2019. Functional and aesthetic outcome has been evaluated in this study. Results: The study included 20 patients with mean age of 18.8 ± 6.2 years, female to male ratio was 1.5:1, and the majority of the cases presented with burn (90%). The Vancouver Scar Scale score was significantly reduced after 1 month of follow-up in which it reduced by 4.12 mm (57.6% reduce from baseline), Mean healing score was 93.5%, and Re-epithelialization after 1 month Was 95.55%, Overall the complication rate is low with 5% had hematoma, 5% had infection and 5% had loss of graft. Conclusion: The use of acellular dermal matrix in conjunction with split thickness skin graft result in substantial improvement in the quality of wound healing and tissue reconstruction.

The effect of double W tension-reduced suture technique on the abdominal scars following the da Vinci robot-assisted gastrectomy for severely obese patients

ObjectiveTo analyze the effect of a new type of tension-reduced suture named “double W tension-reduced suture technique” on the abdominal scars following the da Vinci robot-assisted gastrectomy for severely obese patients.Methods40 abdominal incisions following the da Vinci robot-assisted gastrectomy on severely obese patients from September 1st, 2021 to March 1st, 2022 were comprised in the study. 20 incisions were closed by the conventional full-thickness surgical suture as the control group, and 20 incisions were sewn up by double W tension-reduced suture as the double W group. The scars were assessed at the 1-month follow-up visit using the Vancouver scar scale (VSS), ultrasound and patient satisfaction. Meanwhile, digital photographs of scars were taken as well.ResultsThe VSS score was 6.80 ± 2.16 in the control group, while that of the double W group was 2.60 ± 1.89. The difference between groups was significant. Digital photographs showed that the scar color was not only light and close to the skin color, but also flat and soft in the double W group. Ultrasound showed that the fibers of subcutaneous tissue in the double W group were arranged neatly, the ultrasonic signal intensity was relatively uniform, and the tunnel was small without obvious lacunae. More patients were satisfied and very satisfied with scars in the double W group.ConclusionDouble W tension-reduced suture technique could significantly improve the appearance and reduce comorbidities of scars following the da Vinci robot-assisted gastrectomy for severely obese patients.

Sufficient mesh polyhedral intralesional injection for treatment of keloids.

The recurrence of keloids after intralesional injections is significant, and a review of the literature shows an inconsistent range of success rates. In this study, the modified medical proportion and intralesional injection method were intended to enhance the treatment effect. Twenty patients completed the study. Regional block anesthesia (lidocaine, ropivacaine) was performed. Triamcinolone acetonide (40 mg/mL), 5-fluorouracil (25 mg/mL), and ropivacaine (7.5 mg/mL) were configured in a ratio of 2:1:4 and applied on the lesion by reticular injection (horizontal fan-shaped stratified and vertical shaking pressurized injection). The minimum volume of injection per square centimeter was approximately 3.5 mL. The outcome indicators were the Vancouver Scar Scale (VSS), Visual Analogue Scale (VAS), treatment frequency. The patients had an 82% ± 7% average reduction in VSS scores and 89% ± 13% and 93% ± 10% reductions in VAS scores of pain and pruritus, respectively, after an average of 2.5 ± 0.7 injections administered within 1 year. The sufficient mesh polyhedral intralesional injection can achieve excellent results for the treatment of keloid scars.

A Suture Tips Applied to Rotating Flaps in Reconstructing Facial Defects to Optimize Scarring: A Retrospective Study

Background: Local flap reconstruction is the most common method to repair facial defects. In this study, authors have explored and introduced a modified suture technique with rotation flap to repair facial defects that makes scarring more discreet and easier to perform. Methods: Patients with facial defects who underwent surgical treatment of the rotation flaps reconstructions and were admitted to our department between October 2014 and October 2019 were included in this retrospective study. The rotating flap is designed along the Relaxed Skin Tension Line (RSTLs) and contour lines, parts of patients received modified suture depending on the shape and size of the defect. Observe the flaps’ survival and complications. Assessments of the scars with Vancouver Scar Scale (VSS) regularly and follow-ups. Results: This five-year retrospective study evaluated a total of 56 patients; of these, 45 patients underwent modified suture surgery, the average defects were 19.7±4.5×25.5±5.2mm, and the average duration of follow-up was 13.8±5.0 months. Scar appearance was evaluated using the VSS score, range from 0-5, with an average of 1.6±1.1, and mainly reflected in pigmentation and vascularity. Postsurgical scar concealment is made afterward, and all flaps survive. No hemodynamic disorder or necrosis was found. Conclusion: The rotation flap was designed based on RSTLs/ contour lines to repair the facial defect and make the scarring well concealed. The modified suture method makes the flap line consistent with the RSTLs/ contour line of the facial skin to the maximum extent and leads to better facial aesthetics results.

The effect of incisional negative pressure wound therapy on the improvement of postoperative cosmetic suture wounds and scar hyperplasia.

This study aimed to explore the effects of early incisional negative pressure wound therapy (INPWT) on cosmetic suture wounds and postoperative scar hyperplasia. We retrospectively evaluated 120 patients who underwent abdominoperineal resection at the Changhai Hospital between February 2018 and October 2021 and divided them into two groups according to their treatment: the INPWT group (n = 60) and the control group (n = 60). The quality of post-surgical wound healing in the two groups was evaluated. The Patient Scar Assessment Scale (PSAS), the Vancouver Scar Scale (VSS), and the visual analogue scale (VAS) were used to evaluate the surgical incision scar at 1-year follow-up. At this follow-up visit, 115 patients underwent reexamination; five patients were lost to follow-up, including two patients in the INPWT group and three patients in the control group. The INPWT group showed better wound healing than the control group (P < .05). The proportion of patients who received INPWT was significantly higher in the non-surgical site infection (SSI) group than in the SSI group (P < .05). The PSAS, VSS and VAS scores were significantly improved in the INPWT group compared with those in the control group (P < .05). Our results show that INPWT improved the quality of cosmetic suture wounds and reduced the degree of postoperative scar hyperplasia.

Correlation between Collagen Type I/III Ratio and Scar Formation in Patients Undergoing Immediate Reconstruction with the Round Block Technique after Breast-Conserving Surgery.

The aim of this study was to investigate the relationship between the collagen type I/III ratio and scarring in patients who underwent immediate reconstruction with the round block technique (RBT) after breast conservation surgery. Seventy-eight patients were included, and demographic and clinical characteristics were recorded. The collagen type I/III ratio was measured using immunofluorescence staining and digital imaging, and scarring was assessed using the Vancouver Scar Scale (VSS). The mean VSS scores were 1.92 ± 2.01 and 1.79 ± 1.89, as assessed by two independent plastic surgeons, with good reliability of the scores. A significant positive correlation was found between VSS and the collagen type I/III ratio (r = 0.552, p < 0.01), and a significant negative correlation was found between VSS and the collagen type III content (r = -0.326, p < 0.05). Multiple linear regression analysis showed that the collagen type I/III ratio had a significant positive effect on VSS (β = 0.415, p = 0.028), whereas the collagen type I and collagen type III content had no significant effect on VSS. These findings suggest that the collagen type I/III ratio is associated with scar development in patients undergoing RBT after breast conservation surgery. Further research is needed to develop a patient-specific scar prediction model based on genetic factors affecting the collagen type I/III ratio.

Efficacy of bioabsorbable dressing combined with antibacterial spray for treatment of third-degree burns.

To evaluate the clinical efficacy of a bioabsorbable dressing in combination with antibacterial spray in treating third-degree burns. Patients with third-degree burns in our hospital from February 2019 to February 2020 were enrolled and divided into an experimental group and a control group. In all patients, two wound repair surgeries were performed. During the first surgery, bioabsorbable dressing (PELNAC, Gunze Medical Equipment (Shenzhen) Co. Ltd., China) was used for wound treatment. During the second surgery, autologous split-thickness skin graft was performed. For patients in the experimental group, bioabsorbable dressings (PELNAC) were uniformly applied with antibacterial spray during the operation and during postoperative dressing. For patients in the control group, antibacterial spray was not used. A total of 68 patients took part in the study (experimental group n=36; control group n=32). Infection rate in the experimental group was significantly lower than that in the control group (2.8% versus 21.9%, respectively; p<0.05). The mean wound healing time in the experimental group was shorter by 3.2 days and the wound healing rate of the experimental group was significantly higher than that in the control group (p<0.05). Vancouver Scar Scale (VSS) scores at specific postoperative time intervals were significantly reduced in the experimental group compared with those in the control group (p<0.05). Bioabsorbable dressing combined with antibacterial spray could reduce infection rate, shorten wound healing time and reduce scar formation in repairing third-degree burns.

The dose-effect regularity of artificial dermis combined with growth factor in repair wound of luxation of the bone tendon

To investigate the treatment efficacy of the artificial dermis combined with growth factor surgery in patients with luxation of bone tendon (LBT). A total of 40 patients with LBT in our prospective clinical research are randomly allocated to following four groups: Control, low dose, medium dose, and high dose. The baseline characteristics, skin graft interval time, overage rate of regenerated tissue at bone and tendon, and visual estimation of patients were measured, which were then utilized to assess the treatment efficacy of the artificial dermis combined with growth factor surgery in LBT patients. Our outcomes indicated that the artificial dermis combined with growth factor surgery showed significantly less skin graft interval time, higher overage rate of regenerated tissue at bone and tendon, less Vancouver scar scale score compared to those treated by conventional imaging technology (all P &lt; 0.05). It concludes that the artificial dermis combined with growth factor surgery can improve the treatment efficacy, and the medium dose growth factor is a promise dose to treat the patients with LBT.

Functional and aesthetic outcomes of abdominal full-thickness skin grafts in paediatric postburn digital and palmar flexion contractures.

The study aimed to assess the functional and aesthetic outcomes of abdominal full-thickness skin grafts (FTSGs) in paediatric postburn digital and palmar flexion contractures. The digital and palmar functions and aesthetics of 50 children who met the criteria were evaluated at pre-operation, the 3rd- and 12th-month post-operation, respectively. In the evaluation, the Vancouver Scar Scale (VSS), total active movement (TAM), and Jebsen-Taylor Hand Function Test (JHFT) were used. The contralateral, unaffected hand served as the criteria for functional recovery. The complications of donor sites were observed, and the take rate of skin grafts was calculated. The VSS scores at the 3rd and 12th months post-operation were lower than those before the operation. The TAM of each finger was improved at the 3rd and 12th months post-operation, compared with that before the operation. There was a significant difference in the time to complete the JHFT between the affected hand and the unaffected at the 3rd month post-operation, but no significant difference between them at the 12th month post-operation. The excellent and good take rate of the skin grafts was 90.00%.No donor site complications were observed. The abdominal FTSGs are effective in repairing paediatric digital and palmar scar contractures, with satisfying functional and aesthetic results, especially in large defects after scar release and resection.

Ultrapulse Fractional CO2 Laser With Different Fluences and Densities in the Prevention of Periorbital Laceration Scars: A Split-Scar, Evaluator-Blinded Study.

Periorbital laceration can result in complex, permanent scars, and even lead to serious complications such as cicatricial ectropion. Early intervention with laser devices has been suggested as a novel modality to reduce scar formation. However, no consensus exists regarding the optimal treatment parameters for scar management. This study evaluated the efficacy and safety of ultrapulse fractional CO2 laser (UFCL) with different fluences and densities in preventing periorbital surgical scars. To assess the efficacy and safety of UFCL with different fluences and densities in the prevention of periorbital laceration scars. A prospective, randomized, blinded study was conducted on 90 patients with periorbital laceration scars of 2 weeks old. Four treatment sessions of UFCL were administered to each half of the scar at 4-week intervals, with halves treated with high fluences with low density versus low fluences with low-density treatment. Vancouver Scar Scale was used to assess the 2 portions of each individual scar at baseline, final treatment, and 6 months. The patient's 4-point satisfaction scale was used to evaluate the patient's satisfaction at baseline and 6 months. Safety was evaluated by registration of adverse events. Eighty-two of 90 patients completed the clinical trial and follow-up. There was no significant difference in Vancouver Scar Scale and satisfaction score between different laser settings between the two groups (P > 0.05). Adverse events were minor and no long-term side effects were noted. Early application of UFCL is a safe, strategy to significantly improve the final traumatic periorbital scar appearance. Objective evaluation of scars did not identify differences in scar appearance between high fluences with low density versus low fluences with low density of UFCL treatment. Level III.

The effect of Centella Asiatica cream on scar development in patients who underwent open carpal tunnel release surgery

AimTo evaluate the efficacy of the Centella asiatica extract in a cream preparation for the prevention of scar tenderness formation in patients who underwent conventional open carpal tunnel release (CTR) surgery. Material and MethodsA total of 280 patients with carpal tunnel syndrome who underwent CTR surgery were individually randomized into the intervention (n = 140) and control (n = 140) groups. In the intervention group, a petroleum cream mixture consisting of 1% Centella asiatica extract was applied to the patients’ wrist for 6 months after the sutures were removed. In the control group, no intervention was applied. The Vancouver Scar Scale (VSS), Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) functional score, and Visual Analog Scale (VAS) satisfaction scores were assessed preoperatively and postoperatively. Follow-up evaluations were scheduled at 1, 3 and 6 months after CTR surgery. ResultsThe overall VSS score of the intervention group significantly improved at 3-6 months (-1.260, p = .040). At 6 months after surgery, the mean QuickDASH functional score was 18.54 (range 0.00-63.64, SD 17.4) in the intervention group and 28.70 ± 12 (range: 2.27-40.91) in the control group (p < .04). At 6 months after surgery, the mean VAS satisfaction score was 1.46 ± 1.95 (range: 0-4) in the intervention group and 2.48 ± 1.02 (range: 0-4) in the control group (p < .03). ConclusionThe Centella asiatica cream applied to the wrist after CTR surgery was found to be beneficial in preventing scar tenderness in the thenar and hypothenar regions of the hand.

Reconstruction of the severe Achilles tendon and soft-tissue loss with the bi-pedicled conjoined flap and vascularized fasciae latae: A consecutive case series of 15 patients

BackgroundHistorically, the segmental loss of the Achilles tendon with overlying soft-tissue defects had been frequently reconstructed with the composite anterolateral thigh (ALTP) flap, including the iliotibial tract or fasciae latae. This study aimed to present our modified combination using the bi-pedicled conjoined flap with vascularized fasciae latae, for the approximately total reconstruction of the Achilles tendon and extensive soft tissue. MethodsFrom May 2015 to March 2018, 15 patients (9 male and 6 female) with a mean age of 36 years (ranged, 18–52 years) underwent microvascular Achilles tendon reconstruction. Harvested on the abdomen and groin, the conjoined flap was chimeric with the vascularized fasciae latae. Primary donor-site closure was accomplished in all patients. A standard assessment of the functional and esthetical outcomes was completed. ResultsMean follow-up time was 42 months (ranged, 32–48 months). The average dimension of the conjoined flap was 25 × 14 cm (ranged, 18 × 10–35 × 18 cm), and the average size of the folded fasciae latae was 15 × 6 cm (ranged, 12 × 5–25 × 8 cm). At the last follow-up, the Thompson test was negative in all patients. The mean American Orthopedic Foot and Ankle Society (AOFAS) score was 91.0. The mean Achilles tendon total rupture score (ATRS) was 18.5. The mean Vancouver Scar Scale (VSS) score was 3.0. ConclusionsThe composite bi-pedicled flap including vascularized fasciae latae provides an alternative approach with great functional and esthetic outcomes, in selected patients who suffered severe Achilles tendon and skin defects. The one-stage procedure facilitates better rehabilitation postoperatively.

Meta-analysis of the effects of xenogeneic acellular dermal matrix dressings in the treatment of wounds in burn patients

Objective: To evaluate the efficacy and safety of xenogeneic acellular dermal matrix (ADM) dressings for the treatment of wounds in burn patients. Methods: The meta-analysis method was adopted. Databases including Chinese Journal Full-text Database, Wanfang Database, VIP Database, and Chinese Biomedical Database were retrieved with the search terms in Chinese version of ", , , " and PubMed, Embase, Web of Science, and Cochrane Library were retrieved with the search terms in English version of "xenogeneic acellular dermal matrix, dressing, burn wound, burn" to obtain the publicly published randomized controlled trials on the efficacy of xenogeneic ADM dressings for the treatment of wounds in burn patients from the establishment of each database to December 2021. The outcome indexes included wound healing time, ratio of scar hyperplasia, Vancouver scar scale (VSS) score, ratio of complications, ratio of skin grafting, and ratio of bacteria detection. Rev Man 5.3 and Stata 14.0 statistical softwares were used to conduct a meta-analysis of eligible studies. Results: A total of 1 596 burn patients from 16 studies were included, including 835 patients in experimental group who received xenogeneic ADM dressings therapy and 761 patients in control group who received other methods therapy. The bias risk of all the 16 included studies was uncertain. Compared with those in control group, patients in experimental group had significantly shorter wound healing time, lower VSS scores (with standardized mean differences of -2.50 and -3.10, 95% confidence intervals of -3.02--1.98 and -4.87--1.34, respectively, P values both <0.05), and lower ratios of scar hyperplasia, complications, skin grafting, and bacteria detection (with relative risks of 0.58, 0.23, 0.32, and 0.27, 95% confidence intervals of 0.43-0.80, 0.14-0.37, 0.15-0.67, and 0.11-0.69, respectively, P<0.05). Subgroup analysis showed that the difference of intervention measures in control group might be the source of heterogeneity in wound healing time. There was no publication bias in ratio of scar hyperplasia (P≥0.05), while there was publication bias in wound healing time, VSS score, and ratio of complications (P<0.05). Conclusions: Xenogeneic ADM dressings can shorten the wound healing time of burn patients, reduce the VSS score and the ratios of scar hyperplasia, complications, skin grafting, and bacteria detection.
