Effectiveness of SCAR-Q for assessment of incisional SCAR after implant-based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

Advances in the assessment of cosmetic outcomes, sensory alteration in surgical areas, and health-related quality of life of endoscopic thyroidectomy.

BACKGROUND: Endoscopic thyroidectomy has been preliminarily proven effective and safe for thyroid diseases. The cosmetic outcomes and life quality are critical contents of postoperative assessment. This review will primarily focus on the assessment methods and results related to cosmetic outcomes, sensory alteration of surgical area, and quality of life following endoscopic thyroidectomy. METHODS: A comprehensive search of published articles within the last decade was conducted using the terms "endoscopic/robotic thyroidectomy," "patient satisfaction scores," "questionnaire," "quality of life," and "cosmetic" in PubMed. RESULTS: Assessment methods for postoperative cosmetic satisfaction and sensory alterations encompassed verbal/visual analog scales, scar evaluations, Semmes-Weinstein monofilament tests, and more. The evaluation of postoperative quality of life in endoscopic thyroidectomy involved tools such as SF-36, SF-12, thyroid-specific questionnaires, thyroid cancer-specific quality of life questionnaires (THYCA-QOL), as well as assessments related to voice and swallow function. The cosmetic results of endoscopic thyroidectomy generally surpassed those of open thyroidectomy, while the quality of life in endoscopic procedures was either superior or equivalent to that in open thyroidectomy, especially with respect to general health, role emotion, and vitality. CONCLUSIONS: Assessments of cosmetic outcomes and sensory alterations following endoscopic thyroidectomy predominantly relied on patients' subjective feelings. The objective and subjective perspectives of scar assessments remain underutilized. In addition, postoperative laryngoscopy and voice function assessments in endoscopic thyroidectomy procedures require more attention.

Assessment of health-related quality of life in patients with burns injuries during the COVID-19 epidemic: A critical topic for burn survivors.

PURPOSE: It is well known that the coronavirus disease 19 (COVID-19) epidemic had an adverse effect on the health-related quality of life (HRQOL) of patients with disabilities, or neurological or chronic conditions. The aim of this study was to examine the possible factors affecting HRQOL in patients with burn injuries during COVID-19 epidemic. METHODS: The study included a total of 40 burns patients. The demographic and burn injury information of the patients were recorded. The active range of motion was measured with a goniometer. The HRQOL, community integration, scar tissue quality and anxiety level were evaluated using the Burn-Specific Health Scale (BSHS), the Community Integration Questionnaire Revised (CIQ-R), Patient and Observer Scar Assessment Scale, and the State-Trait Anxiety Inventory, respectively. RESULTS: The history of COVID-19 infection, total burn surface area (TBSA), community integration level, work-related burns, the presence of trunk burn injury, the presence of face burn injury, and the presence of a major burn injury were determined to be significantly associated with the HRQOL of burns patients (p < 0.05). CONCLUSION: The history of COVID-19 infection, community integration level, and burn-related parameters (TBSA, localization, severity etc.) were found to be factors associated with the HRQOL during the epidemic. The history of COVID-19 and community integration level should be evaluated in addition to the burn injury parameters to improve the quality of life of burn survivors. It can be recommended that these clinical parameters should be considered when planning the treatment program during and after the epidemic.

Assessment of Donor Site Scar Outcomes, Healing Time, and Postoperative Complications Associated With Split Thickness Skin Grafts Harvested From the Hair Bearing Scalp.

BACKGROUND: The hair-bearing scalp is an underused donor site for split-thickness skin grafts (STSG). OBJECTIVE: Evaluating the donor site scar outcomes, healing times, and complications associated with STSG harvested from the hair-bearing scalp. MATERIALS AND METHODS: During this prospective observational study, donor site healing was assessed on postoperative Days 8 and 30. Donor site scar outcomes were quantified at 1 month using the Vancouver Scar Scale. All postoperative complications were collected during the 30-day follow-up window. RESULTS: 80% of donor sites was fully healed at 1-week follow-up. Vancouver Scar Scale score at the donor site was 0.26 at 1-month follow-up. All patients experienced full hair regrowth. Maximum pain scores were reported on the night of surgery (Vancouver Scar Scale 1.8), with quick resolution in days to follow. No major complications were reported. All STSG obtained from the scalp had full take and good texture and color match with the recipient site. CONCLUSION: The hair-bearing scalp is an excellent donor site for split-thickness skin graft harvesting.

Working Towards Holistic Scar Assessment and Improved Shared Decision Making in Global Burn Care.

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.

How to evaluate scar colour after burn injuries - A clinical comparison of the Mexameter® and the subjective scar assessment (POSAS/VSS).

INTRODUCTION: Scarring after burn injuries remains one of the major challenges in burn medicine and is the subject of current research. Accurate and high-quality assessment of scars is needed to enable exact outcome evaluation of different treatments. Our aim was to evaluate the most common subjective scar evaluation scores-the POSAS (Patient and Observer Scar Assessment Scale) and VSS (Vancouver Scar Scale)-in comparison with the objective device Mexameter® for colour evaluation. METHODS: A prospective monocentre study was performed, which included 120 examined scar areas of 60 patients with third degree burns who had received skin grafts between 1975 and 2018 with a total burned surface area (TBSA) > 2%. Two different scar areas in comparison with one healthy skin area concerning 'colour', 'pigmentation', and 'vascularization' were evaluated by the Mexameter® MX 18, the OSAS, and the VSS by the same examiner, as well as the PSAS by the patient. RESULTS: The mean TBSA of the 60 patients was 24.3%. In the OSAS, 61% of the scars were evaluated as 'hyper-', 19% as 'hypo-', and 19% as 'mix-pigmented'. Furthermore, 65% of the scars were estimated as highly vascularized. In the Mexameter®, the melanin index values of the scar areas compared to the healthy skin areas showed a small difference of 12 (p < 0.05). The mean difference of erythema between the scar and the healthy skin areas was 84 (p < 0.001). For the Mexameter®, moderate correlations were found when comparing 'erythema' with the OSAS category 'vascularization' (r = 0.33, p < 0.05) and 'melanin' with the OSAS parameter 'pigmentation' (r = 0.28, p < 0.05). When comparing the Mexameter® measurements to the OSAS questionnaire, 27% of the scars were wrongly evaluated as 'hyperpigmented' by the observer and 21% as 'hypervascularized', while showing low measurements in the device. Additionally, a novel Mexameter® ordinal scare scale was calculated. CONCLUSION: In this study, we were able to show on a relatively large patient population that with the Mexameter®, the subjectivity of the scar colour assessment by examiner/patient can be overcome, but precise differentiation can still be ensured with subjective evaluation tools. We further introduced a novel Mexameter® Scar Scale. It is necessary to further investigate the vast range of objective devices and develop scar panels for with an incorporation of objective and subjective devices to further improve reliability with reduced bias in terms of scar assessment.

Evaluation of the efficacy of maintenance therapy for acne vulgaris using adapalene 0.1%/benzoyl peroxide 2.5% gel and benzoyl peroxide 2.5% gel for 24 weeks and assessment of atrophic acne scars using three-dimensional image analysis.

Maintenance therapy after remission of inflammation is strongly recommended in the guideline for the treatment of acne vulgaris published by the Japanese Dermatological Association. One advantage of continuing maintenance therapy is the alleviation of atrophic scarring. This study investigated the efficacy of maintenance therapy using adapalene 0.1%/benzoyl peroxide 2.5% gel and benzoyl peroxide 2.5% gel, and its effects on atrophic scarring. Overall, 126 patients were randomized to the adapalene/benzoyl peroxide group (n = 40), benzoyl peroxide group (n = 44), and control group (without maintenance treatment drugs; n = 42), and 111 of these completed a trial lasting 24 weeks. As the primary endpoint, the treatment success rate (the percentage of patients in whom the number of inflammatory lesions was maintained at ≤10) was 89.2% in the adapalene/benzoyl peroxide group, 87.5% in the benzoyl peroxide group, and 47.4% in the control group. Compared with the control group, the success rates were significantly higher in the adapalene/benzoyl peroxide and benzoyl peroxide groups (P = 0.0006 for both). As one of the secondary endpoints, the rate of change in the number of atrophic scars showed significant improvement from the baseline in the adapalene/benzoyl peroxide and benzoyl peroxide groups at week 24 (P = 0.0004 and P < 0.0001, respectively). Although the three-dimensional image analysis parameters did not change significantly from the baseline in the adapalene/benzoyl peroxide and benzoyl peroxide groups at week 24, significant worsening was noted in the control group (P = 0.0276 for affected area, P = 0.0445 for volume, and P = 0.0182 for maximum depth). Adverse drug reactions were noted in three patients in the adapalene/benzoyl peroxide group (7.5%) but not in the benzoyl peroxide group. These findings suggest that maintenance therapy using adapalene 0.1%/benzoyl peroxide 2.5% gel and benzoyl peroxide 2.5% gel is effective in preventing the worsening of scars in Japanese patients with acne vulgaris.

Development and validation of a risk assessment scale for pathological scarring.

To develop a risk assessment scale for pathological scarring and validate its psychometric properties. This was a methodological study. Researchers developed the scale based on a literature review, qualitative study and Delphi expert consultation. Subsequently, 409 patients participated in the study to test the psychometric properties of the scale. We evaluated construct validity, content validity, internal consistency reliability, and interrater reliability. The researchers developed a scale consisting of three dimensions and 12 items. Factor analysis extracted a total of four common factors that accounted for 62.22% of the total variance. The results revealed that the item-content validity index (I-CVI) ranged from 0.67 to 1, while the scale-content validity index (S-CVI) was 0.82. Internal consistency reliability: Cronbach's α of the items ranged from 0.67 to 0.76, while Cronbach's α of the whole scale was 0.74. Interrater reliability: the Kappa number was 0.73. The final scale showed adequate construct validity, content validity, and reliability. It is appropriate for use in research and clinical practice settings to identify patients with a risk of pathological scarring. Further study is needed to confirm the scale's validity and reliability in other settings and populations.

The practical utility of psychometric scales for the assessment of the impact of posttraumatic scars on mental health.

Background: Scars are a natural consequence of the healing process, but with an impact on the psychological and social level for the individual, which can even lead to withdrawal and social stigmatization. We aimed to analyze the psychosocial impact determined by post-traumatic scars, using psychometric scales, to assess the effectiveness of the Mekereș' Psychosocial Internalization Scale (MPIS), and to identify relevant predictors of traumatic and surgical scar internalization. Methods: Our cohort included 293 participants, 149 women and 144 men, aged 18-64 years who were screened for scar characteristics and completed a set of psychological scales. We compared the results obtained in two subgroups: 153 subjects with posttraumatic scars and 140 with surgical scars. Results: Relevant predictors for posttraumatic scar internalization (R 2 = 0.721) are adaptation time, age of the occurrence and subjective appraisal, while for the depression, and hopelessness relevant predictors are the subjective appraisal of the scars and the posttraumatic quality of life. Conclusion: The psychological and social reporting of the aftermath of trauma, that has been followed by scar-ring, is an indicator of how a person will react and could indicate the susceptibility to psycho-pathology.

Perinatal assessment of complex cesarean delivery: beyond placenta accreta spectrum.

Multiple cesarean deliveries are known to be associated with long-term postoperative consequences because of a permanent defect of the lower uterine segment wall and the development of thick pelvic adhesions. Patients with a history of multiple cesarean deliveries often present with large cesarean scar defects and are at heightened risk in subsequent pregnancies of cesarean scar ectopic pregnancy, uterine rupture, low-lying placenta or placenta previa, and placenta previa accreta. Moreover, large cesarean scar defects will lead to progressive dehiscence of the lower uterine segment with the inability to effectively reapproximate hysterotomy edge and repair at birth. Major remodeling of the lower uterine segment associated with true placenta accreta spectrum at birth, whereby the placenta becomes inseparable from the uterine wall, increases the rates of perinatal morbidity and mortality, especially when undiagnosed before delivery. Ultrasound imaging is currently not routinely used to evaluate the surgical risks of patients with a history of multiple cesarean deliveries, beyond the risk assessment of placenta accreta spectrum. Independent of accreta placentation, a placenta previa under a scarred, thinned partially disrupted lower uterine segment, covered by thick adhesions with the posterior wall of the bladder, poses a surgical risk and requires fine dissection and surgical expertise; however, data on the use of ultrasound to evaluate uterine remodeling and adhesions between the uterus and other pelvic organs are scarce. In particular, transvaginal sonography has been underused, including in patients with a high probability of placenta accreta spectrum at birth. Based on the best available knowledge, we discuss the role of ultrasound imaging in identifying the signs suggestive of major remodeling of the lower uterine segment and in mapping the changes in the uterine wall and pelvis, to enable the surgical team to prepare for all different types of complex cesarean deliveries. The need for postnatal confirmation of the prenatal ultrasound findings for all patients with a history of multiple cesarean deliveries, regardless of the diagnosis of placenta previa and placenta accreta spectrum, is discussed. We propose an ultrasound imaging protocol and a classification of the level of surgical difficulty at elective cesarean delivery to stimulate further research toward the validation of ultrasound signs by which these signs may be applied to improve surgical outcomes.

Magnetic resonance assessment of left atrial scar formation following a novel very high-power short-duration workflow for atrial fibrillation ablation.

AIMS: Atrial fibrillation (AF) ablation protocols using energy delivery with very high power and short duration (vHPSD) have been introduced to improve lesion formation. This study reports procedural data of vHPSD ablation in AF patients and analyses characteristics of ablation-induced left atrial (LA) scar formation from cardiac magnetic resonance imaging (MRI). METHODS AND RESULTS: Sixty consecutive patients undergoing index pulmonary vein isolation following our institutional Q4U-AF workflow were prospectively enrolled. Ablation was conducted using a contact force sensing catheter allowing for vHPSD ablation using a temperature-controlled ablation mode. Thirty patients underwent cardiac late gadolinium enhancement MRI of the LA 3 months after ablation to assess LA scar. Mean procedural duration was 66.5 ± 14.8 min. Mean ablation time was 4.7 ± 0.9 min with a mean number of 69.9 ± 14.2 applications. First-pass isolation was achieved in 51 patients (85%) for the right pulmonary veins (RPVs), in 37 patients (61.7%) for the left pulmonary veins (LPVs), and in 34 patients (56.7%) for both pulmonary veins (PVs). Magnetic resonance imaging at 3 months post-ablation demonstrated a mean scar width of 14.4 ± 2.6 mm around RPVs and 11.9 ± 1.9 mm at LPVs (P > 0.05). Complete PV encirclement was observed in 76.7% for RPVs, in 76.7% for LPVs, and in 66.7% for both PV pairs. During a mean follow-up of 4.7 ± 1.4 months, arrhythmia recurrence was observed in 3.3% of the patients. CONCLUSION: Pulmonary vein isolation following a novel vHPSD workflow resulted in short procedure duration and high acute and mid-term efficacy. Magnetic resonance imaging demonstrated durable and transmural PV lesions with homogeneous and contiguous scar formation.

Assessment of Urinary Level of Neutrophil Gelatinaseassociated Lipocalin (NAGL) in Children with Renal Scar Due to Vesicoureteral Reflux.

INTRODUCTION: Renal scarring is a serious complications of urinary tract infection and vesicoureteral reflux (VUR). The dimercaptosuccinic acid (DMSA) scan is the gold standard method for diagnosing renal scars but is an expensive procedure that risks ionizing materials and is not available to everyone. Neutrophil gelatinase-associated lipocalin (NGAL) increases following inflammation, infection, and acute kidney injury in the urine. The aim of this study was to evaluate the urinary level of NGAL and determine its diagnostic value in renal scarring. METHODS: Patients aged 3 to 60 months with pyelonephritis were included in this study. Voiding cystourethrography (VCUG) was performed in the presence of hydronephrosis on ultrasonography. Children with VUR underwent DMSA scans six months after successful treatment of pyelonephritis., Patients were divided into two groups based on the result of DMSA scan: those with and those without renal scars. Levels of urinary NGAL were measured in both groups. RESULTS: Ninety-two children with VUR (grades 2 to 5) were studied, of whom 40 had renal scars and 52 did not. The urinary level of NGAL at the cutoff point of 284 ng/dL had 70% sensitivity and 100% specificity for the detection of renal scars and was higher in patients with renal scars. (P < .05). CONCLUSION: The urinary level of NGAL is considerably higher in children with renal scarring. It is not a good test for screening and early diagnosis due to its low sensitivity, although it can identify renal scars caused by VUR with high specificity.  DOI: 10.52547/ijkd.6951.

Comparative effectiveness analysis of deep low heat burns in the shin surgical approaches: Outcomes and cost for wound rehabilitation.

A variety of surgical techniques exist for deep burn wounds in the shin at low temperature reconstruction after appropriate debridement, but limited high-quality data exist to inform treatment strategies. Using multi-institutional data, the authors evaluated the length of healing time, cost, and outcomes of three common surgical reconstructive modalities. All subjects with deep burn wounds in the shin caused by low temperature who received direct suture repair, skin grafting, or local flap reconstruction were retrospectively reviewed (from 2015.01 to 2021.03). Mean operation time, mean blood loss in operation, postoperative healing time, whether there is scar depression after operation were the primary outcomes; patient satisfaction score, Vancouver scar scale (VSS) score and average costs were secondary outcomes. Two hundred subjects (68 suture, 87 skin-grafting, and 45 local flap coverage patients) were evaluated. Matched patients (n = 200; 3/groups) were analysed. The average operation time, average operation blood loss, and postoperative healing time were statistically significant differences (P < 0.05). Readmissions and reoperations were greater for direct suture and local flaps, if achievable, direct suture provided success at low cost. Skin grafting was effective with large burn wounds but at higher costs and longer length of stay. Local flaps successfully treated smaller burn wounds unable to suture directly, with less pigmentation and scars, even suitable for older patients. Deep low heat burn wounds in the shin healing can be performed effectively using multiple modalities with varying degrees of success and costs. Direct suture or local skin flap reconstruction, if achievable, provides successful coverage at minimal costs, no skin contractures, and reducing length of hospital stay.

Objective Burn Scar Assessment in Clinical Practice Using the Cutometer©: Introduction and Validation of a Standardized Measurement Protocol.

An objective burn scar assessment is essential to informed therapeutic decision-making and to monitor scar development over time. However, widely employed scar rating scales show poor inter-rater reliability. For this study we developed a standardized measurement protocol for the Cutometer© applicable for objective burn scar assessment in everyday clinical practice. We developed a measurement protocol for the Cutometer© MPA 580 including a scar site relocation technique based on anatomical landmarks. The protocol emerged through several steps: Identifying key factors for valid and reliable measurements, preliminary testing, specification of technical details, refining the protocol and final testing. Consecutively, the protocol was validated for inter-rater reliability by assessing 34 burn scars in 17 patients by four clinicians and computing an Intra-class Correlation Coefficient (ICC). Parameter R0, representing scar pliability, was identified as the best suited output parameter yielding excellent inter-rater reliability for average measures (ICC 0.92 [95% CI 0.86; 0.96]) and acceptable reliability for single measures (ICC: 0.74 [0.61; 0.84]). The pressure applied on the measuring probe was identified as an influential confounding factor for reliable measurements. Rater gender did not influence reliability of measurements. The introduced standardized measurement protocol for the Cutometer© MPA 580 enables an objective and reliable burn scar assessment for clinical as well as research purposes.

Maternal Morbidity After Double Balloon Catheter Management of Cesarean Scar and Cervical Pregnancies.

We performed a retrospective cohort study of all Type 1 cesarean scar pregnancies (n=18) or cervical pregnancies (n=5) at an academic tertiary center after treatment with a cervical double balloon catheter from 2018 to 2022 to evaluate outcomes and maternal morbidity. Cervical double balloon catheter treatment was associated with no cases (95% confidence interval 0-16%) of maternal hemorrhage treated with transfusion, hysterectomy, or ICU admission. Treatment was successfully performed by nine different obstetrics and gynecology specialists.

Assessment of a limited-access parotidectomy technique's complications and scar characteristics - A cohort study.

OBJECTIVE: Parotidectomy is the treatment of choice for benign tumors of the parotid gland, with the modified Blair incision most commonly utilized. This retrospective analysis aimed to determine the incidence of complications and assess the relationship between the mass and scar characteristics, in patients who had undergone parotidectomy. MATERIALS AND METHODS: The scar characteristics of patients who had undergone parotidectomy for benign neoplasms at our medical center between 2013 and 2019 were evaluated. RESULTS: Overall, 49 patients met the inclusion criteria, of whom 33 agreed to participate in the study. The mean patient age was 52.8 years; 57.5% were males. No correlation was identified between the parotid mass size or location and scar type or length. The most common complications in this study were similar to those reported in the literature. CONCLUSION: The results of this study suggest that the smaller, tailored modified Blair incision for parotidectomy does not increase complication rates. Future studies with larger cohorts should be conducted to further assess the potential benefits of tailored incision size during modified Blair parotidectomies.

Periareolar endoscopic minimally invasive cardiac surgery: postoperative scar assessment analysis.

OBJECTIVES: The standard approach for minimally invasive cardiac surgery (MICS) for repair of the atrioventricular valves is a right lateral minithoracotomy. In this study, we report our experience with a periareolar endoscopic approach, which aims at an optimal cosmetic outcome while preserving optimal clinical outcomes. METHODS: All patients underwent periareolar endoscopic MICS using high-definition three-dimensional endoscopic visualization without additional rib-spreading. Patients presented with degenerative and/or functional mitral regurgitation. Patients undergoing concomitant tricuspid valve surgery, cryo-ablation, patent foramen ovale closure, left atrial appendage occlusion and/or left atrial myxoma extirpation were included. This descriptive article analysed the aesthetic and functional outcome of the periareolar scar using 5 most common and clinimetrically sound scar assessment scales. For statistical analysis of the scar assessment grading scales, box and whisker plots were calculated depicting median, interquartile range and high and low range data points. RESULTS: Median scar assessment scale scores for n = 100 male patients (response rate 100/109; 91.7%) were 2 [1, 4], 7.5 [6, 9], 11 [8, 14], 3 [2, 3] and 10 [9, 11] for the Vancouver scar scale, Manchester scar scale, patient scar assessment scale, Stony brook scar evaluation scale and Dermatology Quality of Life Index scale, respectively. Ninety-seven patients received mitral valve repair, 7 mitral valve replacement, whereas 5 had left atrial myxoma extirpation. Concomitant tricuspid annuloplasty, cryo-ablation, left atrial appendage occlusion and patent foramen ovale closure surgery were performed in 12, 29, 5 and 8 patients, respectively. Median procedure, cardiopulmonary bypass and cross-clamp times were 169.5 [154.3, 189.3], 111.5 [97, 127], and 68.5 [58.8, 81] min, respectively. CONCLUSIONS: Periareolar endoscopic MICS is safe and cosmetically appealing. It is feasible and allows for complex mitral valve repair, mitral valve replacement and concomitant surgery. Data from 5 scar assessment scales suggest that this technique delivers patient-satisfying results regarding functional and cosmetic outcomes.

Transplantation of autologous fat, stromal vascular fraction (SVF) cell, and platelet-rich plasma (PRP) for cell therapy of atrophic acne scars: Clinical evaluation and biometric assessment.

BACKGROUND: Scarring is an unfortunate result of acne because it causes the psychological and cosmetic problems for the patients. Unfortunately, no single treatment is suitable, and using multiple methods may have a better result. The autologous fat and stromal vascular fraction (SVF) cells and their secretory factors can enhance the angiogenesis, collagen synthesis, and migration of fibroblasts, therefore regenerate hurt tissues. Moreover, other treatments for acne scarring, such as platelet-rich plasma (PRP), induce the increase in scare. AIMS: This study aimed to verify the effectiveness of transplantation of autologous fat, SVF cells, and PRP as cell therapy techniques on atrophic acne scars. PATIENTS/METHODS: This study included 9 adult patients with atrophic acne scars on face. All patients received the transplantation of autologous fat, stromal vascular fraction (SVF) cells, and PRP. The treatment outcome was measured by biometric assessment (VisioFace 1000 D, Colorimeter, multi-probe adapter Cutometer, Tewameter, Mexameter, and skin ultrasound imaging system), and also, the satisfaction of patients was evaluated. The patients were followed 6 months after the treatment. RESULTS: There was a significant improvement in the skin pores, spots, skin lightness and melanin content of skin, skin elasticity, and TEWL (transepidermal water loss) after 6 months of the treatment. Furthermore, denser skin layers were observed both in the epidermis and in the dermis. Moreover, 66.6% of patients showed good satisfaction after the treatment. CONCLUSION: In brief, the transplantation of autologous fat, SVF cells, and PRP is an effective cell therapy for atrophic acne scars.
