The SCAR (Scar Cosmesis Assessment and Rating) scale: development and validation of a new outcome measure for postoperative scar assessment

Development and Validation of the Oxford Skin Cancer Treatment Scale, a Patient-Reported Outcome Measure for Health-Related Quality of Life and Treatment Satisfaction After Skin Cancer Treatment

BACKGROUND

Patient-reported outcome measures (PROMs) are necessary to assess the value of skin cancer treatment and to better compare therapeutic options.

OBJECTIVE

To develop and validate the Oxford Skin Cancer Treatment (OxSCanTr) scale, evaluating health-related quality of life and satisfaction after skin cancer treatment.

MATERIALS AND METHODS

After qualitative patient interviews, international expert consultation, and item reduction, 2 separate patient samples were used to assess the factor structure of the scale. Exploratory factor analysis with categorical variables and a polychoric correlation matrix followed by promax oblique rotation was performed to establish a factor structure on Group A. Confirmatory factor analysis with a Satorra-Bentler scaled test statistic evaluating the root mean squared error of approximation (RMSEA), standardized root mean squared residual (SRMR), and comparative fit index (CFI) was conducted on Group B. Reliability as internal consistency was assessed using McDonald omega. Convergent and discriminant validity were assessed using the Pearson correlation coefficient.

RESULTS

A total of 480 subjects returned completed surveys (completion rate 96%). A 12-item scale was developed encompassing 4 domains: aesthetic satisfaction, treatment choice satisfaction, treatment experience, and future concerns regarding recurrence/spread. Confirmatory factor analysis showed excellent goodness-of-fit characteristics, with RMSEA = 0.048, SRMR = 0.051, and CFI = 0.962 using the 4-factor model. Reliability was very good (McDonald omega 0.81-0.82), as was convergent validity with the FACE-Q skin cancer module appraisal of scars subscale (r = 0.55). Discriminant validity with a single question regarding being conservative was similarly excellent (r = -0.02).

CONCLUSION

The OxSCanTr scale is a parsimonious, feasible, and valid PROM for the holistic assessment of the experience of patients who have undergone skin cancer treatment.

Vascular anomalies of the limb and trunk in children: a retrospective comparative study of endoscopic surgery and open surgery

BACKGROUND

Endoscopic resection has been reported for vascular anomalies (VA) previously. However, there is no study comparing endoscopic resection surgery (ERS) with open resection surgery (ORS) in children. We aimed to compare clinical and cosmetic outcomes between two approaches in pediatric VA.

METHODS

Between June 2018 and June 2023, 138 pediatric VA patients undergoing ERS or ORS were retrospectively reviewed. Propensity score matching (PSM) was performed to minimize selection bias. The Scar Cosmesis Assessment and Rating (SCAR) Scale and numerical rating scale (NRS) based on patient satisfaction were used for cosmetic assessment.

RESULTS

After PSM for age, depth of lesion, size of lesion, and site of surgery, 72 patients (ERS = 24, ORS = 48) were analyzed. Patients undergoing ERS had longer operative time (164.25 ± 18.46 vs. 112.85 ± 14.26 min; P < 0.001), less estimated blood loss (5.42 ± 2.15 vs. 18.04 ± 1.62 ml; P < 0.001), and shorter median hospital stay (4.50 [3.00-5.00] vs. 6.00 [5.00-6.00] days; P < 0.001). The follow-up time was 8.04 ± 1.23 month for ERS group and 8.56 ± 1.57 month for ORS group. For aesthetic results, the median overall SCAR score in ERS was lower than that in ORS (2 [1-3] vs. 5 [4-5]; P < 0.001), and the subscales of "scar spread," "dyspigmentation," "track marks or suture marks," and "overall impression" were better. The median NRS score was higher (8 [7-8] vs. 6 [5-6]; P < 0.001) and length of scars was shorter (2.18 ± 0.30 vs. 8.75 ± 1.98 cm; P < 0.001) in ERS group than those in ORS group. The incidences of total complications and recurrence showed no significant difference between two groups.

CONCLUSIONS

Endoscopic surgery can be a safe and effective option for pediatric VA in the limbs and trunk. It offers the advantages of improving aesthetic outcomes and reducing postoperative wound healing time.

Hemodialysis Arteriovenous Access Cosmesis Scale (AVACS): A new measure for vascular access

RATIONALE AND OBJECTIVE

This study aimed to develop a cosmesis scale to evaluate the cosmetic appearance of hemodialysis (HD) arteriovenous (AV) accesses from the perspective of the patient and clinician, which could be incorporated into clinical trials.

STUDY DESIGN

Using a modified Delphi process, two AV access cosmesis scale (AVACS) components were developed in a four-round Delphi panel consisting of two surveys and two consensus meetings with two rounds of patient consultation.

SETTING AND PARTICIPANTS

The Delphi panel consisted of 15 voting members including five interventional or general nephrologists, five vascular surgeons, three interventional radiologists, and two vascular access nurse coordinators. Four patients experienced with vascular access were involved in patient question development.

ANALYTICAL APPROACH

For a component to be included in the AVACS, it had to meet the prespecified panel consensus agreement of ⩾70%.

RESULTS

The clinician component of the AVACS includes nine questions on the following AV access features: scarring, skin discoloration, aneurysm/pseudoaneurysms and megafistula appearance. The patient component includes six questions about future vascular access decisions, interference with work or leisure activities, clothing choices, self-consciousness or attractiveness, emotional impact, and overall appearance.

LIMITATIONS

Delphi panel methods are subjective by design, but with expert clinical opinion are used to develop classification systems and outcome measures. The developed scale requires further validation testing but is available for clinical trial use.

CONCLUSIONS

While safety and efficacy are the primary concerns when evaluating AV access for HD, cosmesis is an important component of the ESKD patient experience. The AVACS has been designed to assess this important domain; it can be used to facilitate patient care and education about vascular access choice and maintenance. AVACS can also be used to inform future research on developing new techniques for AV access creation and maintenance, particularly as relates to AV access cosmesis.

Endoscopic approaches to the orbit: Transnasal and transorbital, a retrospective case series

Introduction

Orbital pathologies requiring surgery are traditionally treated by open approach with different techniques depending on the lesion location. Recently, minimally invasive endoscopic approaches, such as the Endoscopic Endonasal Approach (EEA) and the Endoscopic Transorbital Approach (ETA) have been introduced in orbital surgery.

Research question

The purpose of this study is to report the combined experience of the Neurosurgical and Ear-Nose-Throat (ENT) Units in the endoscopic approach of orbital pathologies.

Material and methods

We retrospectively retrieved data on patients treated at our Institution between 2016 and 2021 with endoscopic approach for orbital pathologies. The Clavien-Dindo classification and the Scar Cosmesis Assessment and Rating (SCAR) Scale have been used to assess complications and cosmetic outcomes.

Results

39 patients met the inclusion criteria. EEA (15 patients) or ETA (20 patients) were chosen to approach the lesions. In three cases we used a combination of endoscopic and anterior orbitotomy and in one patient a combination of EEA + ETA. The type of procedure performed was orbital biopsy (9 cases), orbital decompression (6 cases), subtotal resection of the lesion (STR) (8 cases) and total resection of the lesion (GTR) (16 cases). The more frequent postoperative complications were diplopia (5.1%, with 1 case of permanent diplopia), trigeminal paraesthesia and dysesthesia (5.1%), palpebral edema (17.9%), periorbital ecchymosis (7.7%). Mean follow up time was 21 months (range 2-63 months).

Discussion and conclusion

Endoscopic approaches to orbital compartments provide minimally invasive access to every orbital compartment with low complications rate and good cosmetic outcome.

Radially Pedicled In-Situ Split-Thickness Skin Grafts, an Alternative to Distal Split-Thickness Skin Grafts

OBJECTIVE

This study aimed to introduce a novel radially pedicled in-situ split-thickness skin graft (STSG). The morbidity, esthetic, and functional outcomes of the radially pedicled in-situ STSG were in comparison with those of the distal STSG.

STUDY DESIGN

Retrospective analysis.

SETTING

A single-institution review.

METHODS

Seventy patients with oral cancer who underwent radical surgical resection and simultaneous radial forearm free flap (RFFF) reconstruction from July 2021 to March 2022 were included. De-epithelialized RFFFs and traditional RFFFs were used to repair oral defects of 35 patients in Group A and Group B, respectively, while radially pedicled in-situ STSGs and distal STSGs taken from abdomens were used to repair donor site defects in the above groups, respectively. Patient demographics, wound healing complications, and esthetic and functional outcomes of the forearms were compared between the 2 groups.

RESULTS

No significant difference between Group A and Group B was observed in terms of donor site and recipient site complications. The esthetic outcome was superior in Group A compared to Group B (P = .011). The extension range, sensation, and pinch strength of operated forearms were significantly reduced in both groups after surgery (P < .05), however, intergroup differences were not observed.

CONCLUSION

Taken together, our results suggest that radially pedicled in-situ STSG is an applicable technique for direct closure and better esthetic outcomes in the forearm donor site.

TOETVA: a single surgeon's learning curve and a case report of CASTLE thyroid tumor

BACKGROUND

Owing to the lack of visible scars, the transoral endoscopic thyroidectomy vestibular approach (TOETVA) offers superior aesthetic outcomes compared to conventional thyroidectomy. Carcinoma showing thymus-like differentiation (CASTLE) represents a rare thyroid gland neoplasm. This study aimed to explore the TOETVA learning curve and present a case report of CASTLE.

METHODS

A study with precise 1:1 matching was conducted to assess the procedure safety and cancer control outcomes of TOETVA in comparison to conventional surgery between May 2020 and May 2023. Cumulative sum analysis was employed to optimally fit the learning curve. Subsequently, a case report of CASTLE treated with TOETVA surgery was presented.

RESULTS

The mean operative time was longer in the TOETVA group than in the open group. The TOETVA group had a higher incidence of skin numbness and excellent cosmetic outcomes compared to the open group. The learning curves for work area preparation, unilateral thyroid lobectomy, and the entire surgical process were 59, 28, and 50 cases, respectively. There were no differences between the learning and proficient groups, except for operative time, intraoperative blood loss, and drainage volume on the first postoperative day.

CONCLUSIONS

A comprehensive analysis of the TOETVA learning curve utilizing cumulative and analytical methods demonstrated the feasibility of TOETVA with regards to surgical integrity, safety, and oncological safety. This study's findings suggest that a surgeon's cumulative number of TOETVA cases exceeding 50 can reach the mastery stage. Moreover, diagnosing CASTLE is challenging and necessitates immunohistochemical detection of relatively specific markers associated with thymic epithelial tumors.

InCISE: Instrument for Comprehensive Incisional and Surgical Evaluation

OBJECTIVE

The evaluation of healing after head and neck surgery is currently qualitative and non-standardized, limiting the quality of surgical healing assessments in clinical and research settings. We sought to develop an objective, standardized wound assessment score, and hypothesize that a reliable instrument can be developed to evaluate head and neck surgical wounds.

METHODS

A prospective cohort study was conducted in a tertiary-care, academic head and neck surgery practice. Patients undergoing head and neck surgery were enrolled. A digital photograph protocol was developed for evaluating healing surgical wounds. A panel of experts developed and refined a wound healing score and established reliability, reproducibility, internal consistency, and validity of the score.

RESULTS

InCISE: Instrument for comprehensive incisional and surgical evaluation was created. The utility of our wound healing score was assessed using classical test theory. We performed the major steps of establishing reliability in head and neck surgeons: (1) internal consistency (Cronbach's α = 0.81), (2) inter-observer reliability (intra-class correlation = 0.76), and (3) intra-rater reliability (intra-class correlation = 0.87), and content validity (through focus groups). Our composite measure was found to have strong internal consistency, inter-rater reliability, and intra-rater reliability. Preliminary work suggests criterion validity via associations with physical health related quality of life (SF-12).

CONCLUSION

A wound healing score for head and neck surgery, InCISE, has been developed and is reliable, reproducible, and consistent. Although content validity is present and criterion validity is suggested, work continues to establish validity in this instrument to allow for expanded clinical and research use.

Transoral endoscopic thyroid surgery via vestibular approach with silastic chin augmentation genioplasty

From July 2020 to March 2022, 3 patients with papillary thyroid cancer (PTC) and microgenia underwent transoral endoscopic thyroid surgery via a vestibular approach or a endoscopic lateral neck dissection via the breast and transoral approaches with chin silastic augmentation genioplasty performed concurrently. Image documentation, patient satisfaction, complications and other factors such as demographics and clinicopathologic details were recorded. None of the patients developed major complications and there were no complications such as infection or displacement of the implant. All patients were satisfied with the cosmetic outcomes. Despite the study being limited to these 3 selected patients with PTC and microgenia, the follow-up to our initial description of the new technique established its safety and efficacy.

Evaluation of Facial Trauma Scars After Treating by Refining Plastic Surgery Techniques: A Follow-Up Study

BACKGROUND

Although early debridement and refining plastic surgery techniques have been shown to be effective in the treatment of facial scars after trauma, their postoperative outcomes have not been quantitatively evaluated by the relevant Scar Cosmesis Assessment and Rating (SCAR) Scale. This study was designed to provide a fair assessment of the appearance and local symptoms of scars after treatment by refining plastic surgery techniques and to share the operational skills of surgical repairs.

PATIENTS AND METHODS

Patients who received refining plastic surgery techniques were followed up, and facial scars were taken as high-definition photos, which were presented to 6 professional observers, 6 lay observers, and patients themselves to score the facial scars, including: scar spread, erythema, dyspigmentation, track marks or suture marks, hypertrophy/atrophy, itch and pain according to the SCAR.

RESULTS

There were 56 patients who met the inclusion criteria and 25 agreed to participate in the study. No hypertrophic scar was found, and all patients were satisfied with the scar control effect. The scores showed that the treatment was achieved good results in scar spread (pro group: 0.85±0.55, lay group: 0.96±0.68, patients: 0.92±0.64), erythema (pro group: 0.34±0.26, lay group: 0.45±0.37, patients: 0.32±0.48), hypertrophy/atrophy (pro group: 0.21±0.27, lay group: 0.21±0.31, patients: 0.32±0.48), and there was no significant difference in the scores of the 3 observation groups ( P >0.05). However, it is difficult to eliminate dyspigmentation (pro group: 0.29±0.26, lay group: 0.30±0.30, patients: 0.40±0.50), track marks or suture marks (pro group: 0.45±0.33, lay group: 0.59±0.30, patients: 0.36±0.49). Two (8%) patients complained of itch and 1 (4%) patient complained of both itch and pain in the past 24 hours.

CONCLUSIONS

The appearance of facial scars is satisfactory, the local symptoms are mild, and the evaluation among different aesthetics is affirmative after receiving refining plastic surgery techniques, which is just in line with the purpose of seeking beauty for the patients, and meanwhile can provide a good foundation for the comprehensive treatment of late scars, so that the treatment plan should be promoted.

Tailored versus conventional surgical debridement in complex facial lacerations in emergency department: A retrospective study

Surgical debridement is an essential step in treating complex facial lacerations (CFL). As the CFL severity increases, conventional surgical debridement (CSD) of wound edges becomes difficult and may be insufficient. Because the severity and shape of each CFL vary, it is necessary to tailor the customized pre-excisional design, that is, tailored surgical debridement (TSD), for each case before performing surgical debridement. The use of TSD can enable effective debridement of CFL with higher severity. This study aimed to compare the cosmetic outcomes and complication incidence of CSD versus TSD according to CFL severity. In this retrospective observational study, eligible patients with CFL who visited the emergency department between August 2020 and December 2021 were examined. CFL severity was graded as Grades I and II. The outcomes of CSD and TSD were compared using the scar cosmesis assessment and rating (SCAR) scale, wherein a good cosmetic outcome was defined as a SCAR score of ≤ 2. The percentage of good cosmetic outcomes between the 2 groups was compared. The SCAR score and percentage of good cosmetic outcomes between the 2 groups were compared overall and by severity. For analyzing complication incidence, asymmetry, infection, and dehiscence incidence were compared. In total, 252 patients were enrolled [121 (48.0%) CSD and 131 (52.0%) TSD]. The median SCAR scores were 3 (1-5) and 1 (0-2) in all enrolled patients (P < .001), 2 (0-4), and 1 (0-1) in Grade I patients (P < .01), and 5 (4-6) and 1 (1-2) in Grade II patients (P < .001) in the CSD and TSD groups, respectively. The percentage of good cosmetic outcomes was 46.3% and 84.0% overall (P < .001), 59.6% and 85.0% in Grade I patients (P < .01), and 9.4% and 83.5% in Grade II patients (P < .001) in the CSD and TSD groups, respectively. The incidence of complications was significantly higher in the CSD group than in the TSD group, but this was limited to asymmetry. No significant difference was noted in infection or dehiscence. Compared with CSD, TSD can lead to an objectively good cosmetic prognosis at higher CFL severity and can reduce facial asymmetry occurrence.

Effectiveness of various methods of manual scar therapy

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.

Clinical outcomes of a novel porcine small intestinal submucosa patch for full-thickness hand skin defects: a retrospective investigation

OBJECTIVE

To investigate the clinical outcomes of a novel soft tissue repair patch (porcine small intestinal submucosa patch, SIS patch) in the treatment of full-thickness hand skin defects.

METHODS

From January 2017 to July 2019, 80 patients with hand soft tissue defects, who met the inclusion criteria, were retrospectively reviewed and divided into two groups. After debridement, patients in group A were treated with the novel SIS patch to cover the wound, and patients in group B were treated with autologous skin graft. The dimensions of skin defect area and healing outcome were evaluated and recorded. Scar assessment was carried out using Scar Cosmesis Assessment and Rating Scale (SCAR scale) at the last follow-up postoperation, and the recovery of wound sensation was assessed at the same time using British Medical Research Council (BMRC) grading of sensorimotor recovery. All the data were collected and statistically analyzed.

RESULTS

A total of 80 patients were enrolled in the study with 40 patients in each group. Four patients in group A and 5 patients in group B were excluded due to wound infection and lost to follow-up. There were 36 patients in group A and 35 patients in group B finally got follow-up postoperation with mean interval of 12.75 ± 5.61 months in group A and 14.11 ± 5.42 months in group B. The dimensions of skin defect area in group A ranged from 7.5 to 87.5 cm² (mean 25.97 ± 18.66 cm²) and in group B ranged from 7.5 to 86.25 cm² (mean 33.61 ± 19.27 cm²) which have no significant difference (P > 0.05). SCAR scale results of group A and group B were 10.98 ± 0.33 and 9.49 ± 0.35, respectively, and the difference was statistically significant (P < 0.05). BMRC grading results showed 6 cases of S4, 11 cases of S3+, 5 cases of S3, 6 cases of S2, 6 cases of S1 and 2 cases of S0 in group A, and 8 cases of S4, 10 cases of S3+, 7 cases of S3, 4 cases of S2, 5 cases of S1, and 1 case of S0 in group B, which had no significant difference between them (P > 0.05).

CONCLUSIONS

The novel SIS patch is an applicable biological material in the treatment of hand skin defect, which could achieve a better cosmetic appearance of the newborn skin tissue.

Clinical application of absorbable collagen thread and cosmetic suture technique in emergency treatment of children's facial trauma

AIM

To explore the effect of absorbable collagen thread and cosmetic suture technique on scar inhibition after emergency facial trauma in children, and to explore the application value of absorbable collagen thread in emergency facial trauma.

METHODS

Children who received emergency treatment of facial trauma in plastic surgery department from January 2021 to January 2022 were analysed retrospectively, and were divided into absorbable collagen thread group and non-absorbable nylon thread group. The general data, scar appearance and local symptoms of the two groups were analysed, and the scar appearance was scored by scar beauty rating scale and non-inferiority test was analysed statistically.

RESULTS

A total of 632 children with facial trauma were included in this study, including 458 patients with absorbable collagen thread and 174 patients with non-absorbable nylon thread. The SCAR score of the absorbable collagen thread group (3.03 ± 1.57) was similar to that of the non-absorbable nylon thread group (2.98 ± 2.39) (95% confidence interval), and the final scar outcome score was not statistically different (P > 0.05). All families of the patients were satisfied with the results of the procedure, 95% very satisfied.

CONCLUSION

The use of absorbable collagen thread and cosmetic suture technique to treat the wounds of children with facial emergency trauma, resulted in good wound healing, little scar expansion, low incidence of erythema and pigment abnormality, no obvious surgical trace, and no scar hypertrophy or atrophy. The overall impression was good, the pain of stitch removal was avoided for children's patients, and the satisfaction of family members was high. Cosmetic suture technique with absorbable sutures is worthy of clinical application.

Plating versus elastic stable intramedullary nailing for displaced pediatric midshaft clavicular fractures

Introduction

Traditionally, operative treatment for displaced midshaft clavicle fractures in adolescents has been achieved by using a plate and screws. However, a minimally invasive trend has led surgeons to use the elastic stable intramedullary nail (ESIN) for displaced midshaft clavicle fractures. This study aims to compare the clinical outcomes of adolescent patients who were operated on with an ESIN vs. a plate.

Methods

All patients aged between 10 and 14 years with displaced midshaft clavicle fractures who were operated on at our institute between January 2014 and January 2018 were reviewed retrospectively. The preoperative data, including baseline information on the patients, and types of surgical procedure were collected from the hospital database. The postoperative data, including clinical outcome and complications, were collected during the follow-up visits. Clinical outcome was evaluated during outpatient visits using the American Shoulder and Elbow Surgeons (ASES) score. The scar problem was evaluated according to the Scar Cosmesis Assessment and Rating (SCAR) scale.

Results

A total of 73 patients were included. Patients were categorized into two groups: ESIN (n = 45; 27 males, 18 females) and plate (n = 28; 17 males, 11 females), according to surgical technique. The average age of the patients in the ESIN group was 12.2 ± 1.5 years, and that in the plate group was 12.2 ± 1.4 years. The ESIN group presented significantly less operative time (31.1 vs. 59.8 min), a shorter hospital stay (1.5 vs. 2.5 days), and a smaller incision (2.4 vs. 5.4 cm) as compared to the plate group (P < .001). The rate of scar concern was much higher in the plate group (71.4%) than the ESIN group (22.2%) (P < .001). There was no statistically significant difference in shoulder function between the ESIN group and the plate group at different time points.

Conclusion

A conservative approach remains the first choice for a pediatric clavicle fracture. Both the ESIN and the plate are safe and effective treatment methods for displaced midshaft clavicle fractures in adolescents. The ESIN is superior to the plate given its shorter operative time, shorter hospital stay, lower rate of scar concern, and easier implant removal.

Endoscopic Forehead Lift Using Pretrichial Vertical Incisions and Solid Suture Technique: Effective Fixation and Lesser Scar Formation

ABSTRACT

Endoscopic forehead lift with frontal incisions behind anterior hairline has been used conventionally not to exposure scar on the forehead. Accordingly, patients with convex forehead, high hairline, and redundant forehead skin are regarded as not good candidates for endoscopic forehead lift. However, we introduce the advantages of pretrichial vertical incision on the forehead using techniques that minimize the risk of scar formation. Between December 2019 and April 2021, 73 patients who underwent endoscopic forehead lift using pretrichial vertical incision and cortical bone tunnel fixation method were enrolled in this study. One plastic surgeon independently assessed postoperative 6 months scar using Scar Cosmesis Assessment and Rating scale, which include clinician questions and patient questions. Seventy-three patients (67 women and 6 men) with a mean age of 54.5 years (range, 19-76 years) were included in this study. Skin sutures were stitched out 7.15 days after surgery (range, 7-8 days). All patients were followed up over 6 months. "Overall impression" and "patient question" scored zero in all patients. In 14 patients, pencil-thin line was shown, and the other 1 patient showed a little hyperpigmentation in 1 scar out of 3 frontal scars. Erythema, track marks or suture marks, and hypertrophy/atrophy were scored zero in all patients. The worst total score was 1 in 15 patients. Pretrichial vertical incision with cortical bone tunnel fixation using nonabsorbable suture provides several advantages comparing to conventional incision behind anterior hairline. Scar, which is the only potential concern, was not substantive problem and can be overcome with our techniques.

The Supraorbital Approach via an Eyebrow Incision: Analysis of Cosmetic Outcomes Using the Scar Cosmesis Assessment Rating Scale

ABSTRACT

The supraorbital craniotomy through an eyebrow incision, referred to as the suprabrow approach, may be used to access intracranial lesions. Though offering good surgical exposure for anterior base cranial lesions, the suprabrow approach has a paucity of studies on its cosmetic outcomes. In this study, we aimed to assess the cosmetic outcomes of suprabrow approach using validated Scar Cosmesis Assessment Rating (SCAR) scale for the first time. Three patients underwent a suprabrow approach for resection of a suprasellar or frontal mass. Their postoperative courses were followed, with specific attention to the cosmetic outcome of their procedures. The SCAR scale was used to determine the cosmetic success of the approach. We found that all 3 patients scored ≤ 5 on the SCAR scale. All 3 resections were successful with no major postoperative complications. The only minor complication was transient hypoesthesia of the ipsilateral forehead that was noted in all 3 patients.This study quantified the positive cosmetic outcomes of a minimally invasive suprabrow approach. The suprabrow approach provides acceptable surgical exposure and access in an appropriately selected patient with anterior cranial base lesions and results in favorable cosmesis. Although transient hypoesthesia in the distribution of the ophthalmic branch of the trigeminal nerve occurs, the overall benefits of the approach and desirable cosmetic outcomes make the suprabrow approach a good technique to access intracranial lesions in appropriate cases.

A Scoping Review of the Methodology Used in Studies of Genetic Influences on the Development of Keloid or Hypertrophic Scarring in Adults and Children After Acute Wounding

Significance: Keloid and hypertrophic scarring are common following acute wounds. However, the variability in scarring outcomes between individuals and in particular, the association between genetic factors and scarring, is not well understood. This scoping review aims to summarize the methodology used in studies of genetic influences on the development of keloid or hypertrophic scarring in adults and children after acute wounding. The objectives were to determine the study designs used, the characteristics of participants included, the tools used to assess scarring and the length of follow-up after wounding.

Recent Advances: The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Medline, Excerpta Medica Database (EMBASE), Web of Science, Biosciences Information Service (BIOSIS), Prospective Register of Systematic Reviews (PROSPERO), The Human Genetic Epidemiology (HuGE) Navigator (database of genetic association studies), and the genome-wide association study Catalog were searched from January 2008 to April 2020. Cohort studies and case–control studies that examined the association between one or more genetic variations and the development of keloid or hypertrophic scarring were eligible for inclusion. A narrative synthesis that grouped studies by wound type was conducted.

Critical Issues: Nine studies met the inclusion criteria (five in burns, four surgical wounds, and none in other types of acute wounds). Seven assessed hypertrophic scarring, one keloid scarring, and one both scar types. Seven studies used a prospective cohort design. All studies used subjective methods (clinician or patient observation) to assess scarring. There was considerable variation in how scar scales were operationalized.

Future Directions: This review identified a small body of evidence on genetic susceptibility to scarring after acute wounding. Further studies are needed, and in a wide range of populations, including patients with wounds caused by trauma.

Involvement of COL5A2 and TGF-β1 in pathological scarring

Dysregulation in the cutaneous wound-healing process is a consequence of alterations in the efficiency and activity of the various components involved in the healing process. This dysregulation may result in various clinical appearances of a lesion, such as skin ulcers, keloids, hypertrophic and atrophic scars. The collagen type V alpha 2 (COL5A2) gene provides a template for a component of type V collagen, found primarily within the skin basement membrane. Transforming growth factor (TGF)-β is involved in inflammation, angiogenesis, proliferation of fibroblasts, collagen synthesis and extracellular matrix remodeling. Hypertrophic scar fibroblasts possess a disrupted expression pattern of the TGF-β signaling compared to normal healing, while an increased TGF-β signaling reduces the epidermal proliferation rate, triggering atrophic scarring. In the present study, 71 female patients who had undergone planned Caesarean section, without postoperative complications, were examined. These patients were clinically and molecularly evaluated after developing scars in order to determine the role of TGF-β1 (rs201700967 and rs200230083) and COL5A2 (rs369072636) in pathological scarring. Clinical scar evaluation was carried out using SCAR and POSAS scales and genotyping was performed by RT-PCR. No statistical differences were found between the subgroups regarding the genotype and the pathological scarring, since all the patients included were wild-type allele carriers. Further investigations and a more representative study group may highlight the involvement of COL5A2 and TGF-β1 single nucleotide variants in pathological scarring.

Reliability as internal consistency using Cronbach's alpha. Convergent and discriminant validity using Pearson correlation coefficients.

RESULTS

The sample included 351 respondents in the USA and the factorial structure was confirmed using a separate set of 348 respondents in the UK. The OPAS-C had excellent goodness of fit characteristics, with an RMSEA of 0.047 (90% CI 0.037 to 0.056), SRMR of 0.043 and CFI of 0.962. Reliability was excellent, demonstrating Cronbach's alpha of 0.87 in both the US and UK samples. Convergent validity showed correlation coefficients of 0.54 and 0.49 in the US and UK samples, respectively. Discriminant validity demonstrated correlations of 0.21 and 0.26 in the US and UK samples, respectively.

CONCLUSIONS

The OPAS-C represents the first validated scale that addresses mental health measures and public health-relevant responses to COVID-19, and may be a useful measure for use in future longitudinal and cross-sectional studies. Further international validation beyond the USA and UK may be helpful.

Validated Outcome Measures and Postsurgical Scar Assessment Instruments in Eyelid Surgery: A Systematic Review

BACKGROUND

Determining which postsurgical scar assessment instruments, if any, cover important eyelid outcome measures can either attest to the strength of one or more instruments or reveal the need for a more comprehensive scale.

OBJECTIVE

To systematically review validated outcome measures after eyelid surgery and postsurgical scar assessment tools to see whether any individual or combination of 2 assessment tools encompass all relevant, validated eyelid outcome measures.

METHODS

Systematic reviews of validated eyelid outcome measures and postsurgical scar assessment tools were conducted using PubMed/MEDLINE and Ovid. Outcome measure papers that met inclusion criteria were sorted into 8 categories: Patient Subjective, Visual Function, Mechanical Function, Daily Activities, Adverse Effects, Aesthetic Quantitative: Clinical Measurements, Aesthetic Qualitative: Global, and Aesthetic Qualitative: Specific. Outcome measure papers were categorized into tiers of evidence support, and assessment tools were evaluated based on which outcome measures each covered.

RESULTS

No one or combination of 2 assessment tools covered all selected eyelid outcome measures. Although measures related to the subjective patient experience were included in several of the assessment scales, none covered measures of visual function or eyelid-specific clinical measurements.

CONCLUSION

There is currently no existing postsurgical scar assessment instrument that covers all important eyelid-specific outcome measures.

Comparison of Postoperative Outcomes Between Traditional Longitudinal Incision and Bikini Incision in Total Hip Arthroplasty via Direct Anterior Approach: A Randomized Controlled Trial

BACKGROUND

The purpose of this study is to compare a traditional longitudinal incision to an oblique "bikini" incision during total hip arthroplasty (THA) via direct anterior approach (DAA), in terms of the aesthetic appearance of the scar, postoperative functional recovery, and complications.

METHODS

This study is a single-surgeon experience in the Chinese population. Patients who came to our institute needing a THA via DAA were enrolled in our randomized controlled trial and randomly allocated to undergo traditional longitudinal incision (control) or bikini incision. Primary outcomes were measured using the scar cosmesis assessment and rating scale, the visual analog scale for pain, Oxford hip score, and University of California Los Angeles activity-level rating. Secondary outcomes were postoperative serum markers of muscle damage, inflammation, hemoglobin drop, and implant stability. The occurrence of postoperative complications, such as nerve and wound healing, was also recorded.

RESULTS

There were no differences in demographic or clinical characteristics before surgery. A greater proportion of patients in the bikini group were satisfied with the appearance of their scar, giving significantly better scar cosmesis assessment and rating scores. There was no difference in postoperative functional recovery, levels of serum markers, or positioning of the implant components. Incision type had no effect on duration of hospitalization. The incidence of complications did not differ significantly between groups.

CONCLUSION

The bikini incision can improve patients' subjective satisfaction with scar aesthetics after THA via DAA and does not detract from a quick functional recovery. Studies with larger sample sizes should be conducted to further investigate associated complications.

The use of the Scar Cosmesis Assessment and rating scale to evaluate the cosmetic outcomes of totally thoracoscopic cardiac surgery

Background

Conventional median sternotomy is widely used in cardiac surgery, while thoracoscopic cardiac surgery, which is considered to have aesthetic advantages, is being performed increasingly more often in China because patients’ requests for minimally invasive procedures yielding aesthetically pleasing results have significantly increased. Few studies have been conducted to assess surgical scars after cardiac surgery. Compared to the median sternotomy approach, multiple-incision totally thoracoscopic cardiac surgery requires smaller but numerous and scattered incisions. In addition to two working ports on the upper and lower margins of the right breast, an inguinal incision and an axillary incision are made. Therefore, does totally thoracoscopic cardiac surgery truly have aesthetic advantages? This study has the following objectives: (a) to compare median sternotomy cardiac surgery and total thoracoscopic cardiac surgery in terms of the long-term cosmetic outcomes of post-operative scars and (b) to evaluate the effectiveness of the Scar Cosmesis Assessment and Rating scale in combination with the numeric rating scale in the assessment of surgical scars after cardiac surgery.

Methods

Consecutive patients who visited our institution from January 2019 to May 2019 for cardiac surgery via median sternotomy or the totally thoracoscopic approach and followed up for at least one year were included. Inter-rater reliability, internal consistency and convergent validity were evaluated for the Scar Cosmesis Assessment and Rating scale and the numeric rating scale. Clinical characteristics and the scores of the two scales were compared between the two groups using Student’s t test or the Mann-Whitney U test.

Results

Thirty-one patients underwent cardiac surgery via the totally thoracoscopic approach, and 42 patients underwent cardiac surgery via the median sternotomy approach. No significant differences were found in the demographic or clinical data between the two groups. The validity and reliability of the two scales were satisfactory. For the Scar Cosmesis Assessment and Rating scale, the median sternotomy group scored statistically significantly higher than did the totally thoracoscopic group on the “overall impression” and “patient question” subscales (P < 0.05). The overall scores of the Scar Cosmesis Assessment and Rating scale and numeric rating scale were statistically significantly different (P < 0.05).

Conclusions

The Scar Cosmesis Assessment and Rating scale in combination with the numeric rating scale is an effective tool for the assessment of scar aesthetics after cardiac surgery. Surgical scars of totally thoracoscopic cardiac surgery can yield desirable cosmetic outcomes in Chinese individuals, especially in susceptible individuals with a high risk of keloid and hypertrophic scars. Patients with appropriate indications can undergo cardiac surgery with the totally thoracoscopic approach and exhibit a satisfactory scar appearance.

Comparison of Postsurgical Scars Between Vegan and Omnivore Patients

BACKGROUND

Postsurgical skin healing can result in different scars types, ranging from a fine line to pathologic scars, in relation to patients' intrinsic and extrinsic factors. Although the role of nutrition in influencing skin healing is known, no previous studies investigated if the vegan diet may affect postsurgical wounds.

OBJECTIVE

The aim of this study was to compare surgical scars between omnivore and vegan patients.

METHODS AND MATERIALS

This is a prospective observational study. Twenty-one omnivore and 21 vegan patients who underwent surgical excision of a nonmelanoma skin cancer were enrolled. Postsurgical complications and scar quality were evaluated using the modified Scar Cosmesis Assessment and Rating (SCAR) scale.

RESULTS

Vegans showed a significantly lower mean serum iron level (p < .001) and vitamin B12 (p < .001). Wound diastasis was more frequent in vegans (p = .008). After 6 months, vegan patients had a higher modified SCAR score than omnivores (p < .001), showing the worst scar spread (p < .001), more frequent atrophic scars (p < .001), and worse overall impression (p < .001).

CONCLUSION

This study suggests that a vegan diet may negatively influence the outcome of surgical scars.

Health-related quality of life following minimally invasive totally endoscopic mitral valve surgery

BACKGROUND

To compare the impact of two different types of mitral valve surgery on health-related quality of life, we conducted a retrospective study comparing modified totally endoscopic mitral valve surgery with median sternotomy mitral valve surgery.

METHODS

A total of 163 patients who underwent mitral valve surgery at our institution between January 1, 2019 and December 31, 2019 were enrolled. For these 163 patients, mitral valve surgery was performed using either a modified totally endoscopic approach or median sternotomy approach. We used the numerical rating scale and the Scar Cosmesis Assessment and Rating Scale to measure pain intensity and the aesthetic appearance of the surgical incision and used the MOS 36-item Short-Form Health Survey to assess health-related quality of life.

RESULTS

Seventy-eight patients underwent the modified totally endoscopic mitral valve surgery, and eighty-five patients underwent the median sternotomy mitral valve surgery. The two groups of patients were similar in terms of demographics and echocardiography findings. The number of bioprosthetic valve replacements performed was significantly higher in the totally endoscopic group than in the median sternotomy group (p = 0.04), whereas the subvalvular apparatus was less preserved in only 33 cases in the totally endoscopic group (p = 0.01). The rate of postoperative adverse events was similar between the two groups. The pain was mild and aesthetic appearance was significantly better in the totally endoscopic approach group than in the sternotomy approach group. Significant differences in the scores for the bodily pain and mental health subscales of the MOS 36-item Short-Form Health Survey were found between the two groups.

CONCLUSIONS

Compared with median sternotomy mitral valve surgery, totally endoscopic mitral valve surgery has an equally good treatment effect, improving patient's health-related quality of life with a better cosmetic appearance and a lower pain intensity. Our study suggested that the totally endoscopic approach is superior to the median sternotomy approach in terms of pain intensity, aesthetic appearance and health-related quality of life.
