A comparative study evaluating the clinical efficacy of skin tapes versus silicone gel for the treatment of posttrauma scar in the rabbit model

Background: Skin tape and silicone gel are two common over-the-counter preparations used to enhance the cosmesis of keloids and hypertrophic scars of posttrauma wounds. This animal study was performed to determine the clinical efficacy of skin tape versus silicone gel in subjects with scars. Materials and Methods: Three New Zealand rabbits that received total 12 incision wounds which two incision wounds on one ear side and subsequent primary suturing were studied. Stitches were removed after 1 week. Silicone gel was applied right upper side of the rabbit's ear directly on surgical incision wounds, and skin tapes were also applied left upper side of the rabbit's ear directly on another surgical incision wounds after 1 week of surgery. The lower incisions in both ears were covered with sterilized gauze and served as controls. We compared two experimental groups at binaural with using Vancouver Scar Scale, Manchester Scar Scale, and The Stony Brook Scar Evaluation Scale. These are widely used in clinical practice and research to document change in scar appearance. Results: We describe a rabbit model for incisional wounds and scarring outcome measures. The results of scar measuring devices demonstrated that skin tape reduced scar formation as well as silicone gel. Conclusions: The results of cosmetic demonstrated that skin tape reduced scar formation as well as silicone gel. However, the economical and effective materials were the important subject that suffices for clinical requirement. The application of these scar prevention devices to reduce scar formation after surgical incision is worthy of future investigation. Moreover, skin tape may represent a low-cost alternative and low scar formation for closure of surgical incisions.

A practical and objective approach to scar colour assessment

Scarring is a significant clinical problem following dermal injury. However, scars are not a single describable entity and huge phenotypic variability is evident. Quantitative, reproducible inter-observer scar assessment is essential to monitor wound healing and the effect of scar treatments. Scar colour, reflecting the biological processes occurring within a scar, is integral to any assessment. The objective of this study was to analyse scar colour using the non-invasive Eykona® Wound Measurement System (the System) as compared against the Manchester Scar Scale (MSS). Three dimensional images of 43 surgical scars were acquired post-operatively from 35 patients at 3-6 months and the colour difference between the scar and surrounding skin was calculated (giving ΔLab values). The colourimetric results were then compared against subjective MSS gradings. A significant difference in ΔLab values between MSS gradings of "slight mismatch" and "obvious mismatch" (p<0.025) and between "obvious mismatch" and "gross mismatch" (p<0.05) were noted. The System creates objective, reproducible data, without the need for any specialist expertise and compares favourably with the MSS. Greater scar numbers are required to further clinically validate this device--however, with this potential to calculate scar length, width, volume and other characteristics, it could provide a complete, objective, quantitative record of scarring throughout the wound-healing process.

The use of a non cultured autologous cell suspension to repair chronic ulcers

The purpose of this uncontrolled study was to evaluate the clinical effectiveness of ReCell(®) system in the treatment of chronic ulcers. From October 2011 to July 2012, 20 patients, 8 men and 12 women with a mean age of 70 years, with chronic ulcers of different aetiology that were unresponsive to conventional therapies were recruited and treated using the ReCell(®) system. Patient pain rate, scar aesthetics and patient satisfaction were assessed using a Visual Analogue Scale, Manchester Scar Scale and the Rosenberg Self-Esteem Scale, respectively. Complete ulcer healing, defined as 100% reepithelialisation was observed between 40 and 60 days in 14 patients (70%) depending on the type of ulcer and comorbidity. At day 60 postprocedure, 80% reepithelialisation was present in five patients (25%), while one patient with concomitant psoriasis had 50% reepithelialisation. Pain scores improved by day 7 postprocedure. The function and aesthetics of the ReCell-treated patients were good. It is concluded that the ReCell technique may have provided the regenerative tissue stimulation necessary for the rapid healing of chronic ulcers, including those not responsive to more traditional methods.

Exploring Reliability of Scar Rating Scales Using Photographs of Burns From Children Aged up to 15 Years

Assessing burn scars from photographs is a common practice given the growing trend to support health service delivery via electronic media (eg, email, videoconferencing). Scar rating scales, originally designed for in-person assessment, have been used to rate scars from photographic images. Evidence for the reliability of this practice is lacking. Five raters completed three scar rating scales (Patient and Observer Scar Scale, Manchester Scar Scale, modified Vancouver Scar Scale), both in-person and using photographs on 12 participants (seven male, five female) with 18 scar areas (3 × 3 cm). Interrater reliability for the scar parameters of vascularity, color, contour, pliability, and overall opinion achieved intraclass correlation coefficient values of between 0.71 and 0.87 (in-person) and 0.72 and 0.77 (using photographs) for multiple raters. The level of agreement between in-person and photographic assessment was below acceptable levels, which brings into question construct validity when scar rating scales are used in a way for which they were not designed. Reliability estimates in this study were likely reduced by the underrepresentation of scars in the more severe range. This limitation needs to be addressed in future research. Advances are required in the development and refinement of burn scar rating scales, specifically for photographic use, given their routine use in clinical care.

A nude mouse model of hypertrophic scar shows morphologic and histologic characteristics of human hypertrophic scar

Hypertrophic scar (HSc) is a fibroproliferative disorder that occurs following deep dermal injury. Lack of a relevant animal model is one barrier toward better understanding its pathophysiology. Our objective is to demonstrate that grafting split-thickness human skin onto nude mice results in survival of engrafted human skin and murine scars that are morphologically, histologically, and immunohistochemically consistent with human HSc. Twenty nude mice were xenografted with split-thickness human skin. Animals were euthanized at 30, 60, 120, and 180 days postoperatively. Eighteen controls were autografted with full-thickness nude mouse skin and euthanized at 30 and 60 days postoperatively. Scar biopsies were harvested at each time point. Blinded scar assessment was performed using a modified Manchester Scar Scale. Histologic analysis included hematoxylin and eosin, Masson's trichrome, toluidine blue, and picrosirius red staining. Immunohistochemistry included anti-human human leukocyte antigen-ABC, α-smooth muscle actin, decorin, and biglycan staining. Xenografted mice developed red, shiny, elevated scars similar to human HSc and supported by blinded scar assessment. Autograft controls appeared morphologically and histologically similar to normal skin. Xenografts survived up to 180 days and showed increased thickness, loss of hair follicles, adnexal structures and rete pegs, hypercellularity, whorled collagen fibers parallel to the surface, myofibroblasts, decreased decorin and increased biglycan expression, and increased mast cell density. Grafting split-thickness human skin onto nude mice results in persistent scars that show morphologic, histologic, and immunohistochemical consistency with human HSc. Therefore, this model provides a promising technique to study HSc formation and to test novel treatment options.

Is single-port laparoscopy for benign adnexal disease less painful than conventional laparoscopy? A single-center randomized controlled trial

To determine whether laparo-endoscopic single-site surgery (LESS) results in less postoperative pain and a better cosmetic surgical scar compared with conventional laparoscopy. Prospective randomized controlled trial. A county hospital in Norway. Forty women with benign adnexal disease or a hereditary cancer risk scheduled for laparoscopic adnexal surgery. LESS or conventional laparoscopy. Postoperative pain 24 hours after surgery. There was no difference in pain at 24 hours after surgery, with a mean score of 3.0 (SD 2.1) in the LESS group and 2.5 (SD 1.5) in the conventional laparoscopy group. Significantly more shoulder tip pain was reported by women undergoing LESS compared with those having conventional surgery at 6 and 24 hours after surgery. A high satisfaction with the cosmetic result was reported in both groups, with no significant difference in the Manchester scar scale score. Although similar levels of postoperative pain are experienced by women having LESS and conventional laparoscopic surgery, women having LESS report significantly more shoulder tip pain compared to those having conventional laparoscopic surgery. This may relate to a significantly longer operation time in the LESS group. NCT01288599.

A Long-term Follow-up Study of Acellular Dermal Matrix With Thin Autograft in Burns Patients

We report long-term follow-up results of acellular dermal matrix (ADM) allograft combined with thin split-thickness skin autograft (STSG) for burn treatment. Between March 2001 and May 2007, we treated 19 cases of burn wounds or scar wounds at 34 different body sites with ADM allograft combined with STSG. All patients were monitored, with the mean follow-up period being 3.3 ± 1.4 years. Transplant skin was assessed by using a modified Manchester Scar Scale. The control sites that were treated with STSG at the same time were also monitored. There were significant differences in contour, contracture, and texture between the treatment and control sites (P < 0.05), but not in color, sensation, and complications (P > 0.05). All composite-grafted joints showed recovery and improvement in function postoperatively. The aesthetic contour of the skin donor site was satisfactory. Composite graft with ADM produces a supple texture without contractures, approaching the normal skin contour, and leading to adequate improvement in function.

Transverse incision advantages for total knee arthroplasty

BackgroundIf a transverse incision can be safely used for total knee arthroplasty (TKA), decreases in scar formation, reduced injury of the infrapatellar branch of the saphenous nerve and improved kneeling motion will be observed. MethodsWe evaluated 95 patients (101 knees) on whom primary TKA was performed with follow-up of more than 2 years. A longitudinal incision was used for the first 40 knees and a transverse incision for the remaining 61 knees. Operation time, blood loss, complications and Knee Society Score were evaluated. Wound lengths, widths and the Manchester Scar Scale (MSS) were measured 1 year after the surgery. Further examination evaluated sensory disturbances and whether kneeling was possible. ResultsThe complication rate in both groups was almost the same. The wound lengths measured at a 90° knee-flexed position were about 15 cm with no significant difference between the groups. The average width measured at a maximum area was significantly smaller in the transverse group than in the longitudinal group. MSS of the transverse group was also significantly lower than that of the longitudinal group. Sensory disturbance was found to be significantly smaller in the transverse group than in the longitudinal group both in subjective and objective evaluation at 1 year after surgery. When a transverse incision was used, the direction of the incision corresponded to the running direction of the saphenous nerve, and thus, we were able to reduce sensory disturbances on the distal lateral side of the knee joint. The transverse group (70.4%) performed significantly better than the longitudinal group (40.6%) at kneeling motion. ConclusionsWe showed that making a transverse incision is a safe method, resulting in a reduction of scar formation and less dysfunction of the infrapatellar branch of the saphenous nerve, and improvement of kneeling motion.

Patient satisfaction and clinical results 10 years after modified open thoracoplasty for pectus deformities

Indications for surgical treatment for patients with pectus excavatum and carinatum are psychosocial issues, pulmonary or cardiac limitations or pain. When surgery is indicated in our institution, patients are treated with a modified thoracoplasty according to the Ravitch technique. In order to stabilize pectus excavatum, an allogenic bone strut is transplanted which does not require removal. Seventy-one patients with a mean age of 17years who were treated for pectus deformities between 1997 and 2007 were evaluated retrospectively. The average period of follow-up was 5.3years. Sixty-six percent of the patients suffered from pectus excavatum, 34% from pectus carinatum. One osseous revision had to be performed after overcorrection of pectus carinatum into pectus excavatum. Six minor complications occurred. At follow-up, the mean patient satisfaction score was 4.3 (scale 1-5). The Manchester Scar Scale resulted in 96% cosmetically well-healed scars. Clinically, 93% of the surgical results were rated good. This study retrospectively shows that this modification of the Ravitch approach is a safe and effective treatment option for pectus deformities with long-term satisfactory results for the patients without the need for bar removal.

The use of MatriDerm® and skin grafting in post-traumatic wounds

The aim of this study was to prove the effectiveness of MatriDerm(®) combined with skin grafting versus skin grafting alone in post-traumatic wounds treatment. At the Department of Plastic and Reconstructive Surgery of the University of Rome Tor Vergata, we treated 60 patients: 30 patients with dermal substitutes (MatriDerm(®)) combined with autologous skin graft and 30 with skin graft alone. Two weeks after the first treatment, 95% of wounds treated with MatriDerm(®) and skin graft showed a re-epithelisation, whereas it was 75-80% in the control group. We used the Manchester Scar Scale (MSS) and patient's self-estimation scale to assess the outcomes. Mann-Whitney U test was performed for the five items of the MSS and the results were combined to those of patient's self-estimation scale and the re-epithelialisation percentage to test the significance between the two groups. These data confirm the evidence of the clinical use of MatriDerm(®) technology in the healing of soft tissue wounds and prove the effectiveness of combining MatriDerm(®) and skin grafting for the first time. Furthermore, we observed a percentage reduction of wound contraction and in the same time an improvement of elasticity, quality of scars tissue and dermal architecture.

Health Professionalsʼ and Consumersʼ Opinion: What Is Considered Important When Rating Burn Scars From Photographs?

With advances in wound care technology, there is a trend toward patients undertaking specialist burns treatment in an outpatient capacity. Photographic scar evaluation is a part of this trend in some health services because it permits scar assessment by different health professionals, both within and across outpatient services, to assess the impact of scar management strategies. The aim of this study was to explore the parameters considered integral to scar assessment when completing photographic scar evaluation. First, opinions were sought from 38 burn health professionals in 2 tertiary pediatric hospitals who participated in focus groups where in-person and in-photograph scar rating were completed using three burn scar rating scales (modified Vancouver scar scale, Manchester scar scale, and patient and observer scar assessment scale) presented with a standard format and instructions. Second, 36 occupational therapists and physiotherapists from Australia and New Zealand completed questionnaires. Third, 10 healthcare consumers from 1 tertiary pediatric hospital participated in face-to-face or telephone interviews. Parameters believed to be assessed using photographic evaluation of burns scarring were vascularity, surface area, color, contour, height, and overall opinion. However, surface area was considered questionable as an indicator of scar maturity. These parameters mostly differ from those considered important in a burn scar outcome measure when rating scars in-person: height/thickness, vascularity, color, pliability, joint function, and patient/client opinion. A categorical scale with visual descriptors, as well as specific strategies to improve photographic technique, may go some way to addressing the perceived difficulty in rating these parameters using burn scar photographs.

Aesthetic Improvements of Skin Grafts in Nasal Tip Reconstruction

Defect closure on the nasal tip subunit still remains challenging. Full-thickness skin transplantation still is used despite its poor outcome in terms of the nasal tip contour caused by lack of dermal tissue. To avoid subsidence deformities associated with nasal tip reconstruction with skin transplants, this study analyzed methods using combined epidermal and dermal replacement. For 30 consecutive patients with a nasal tip defect, a retrospective comparison was made between conventional full-thickness skin transplantation, retroauricular perichondrodermal composite grafts, and skin transplantation supplemented with the collagen-elastin matrix, Matriderm, used as a dermal substitute (n=10 per study group).The postoperative results were evaluated in a randomized and blind manner by external facial surgeons using the Manchester Scar Scale. The findings showed a marked improvement in nasal tip contour with combined epidermal/dermal replacement without any deterioration in other graft qualities, justifying the additional effort involved in this procedure. Two patients developed fistulae after Matriderm-aided skin transplantation. Therefore, the authors do not consider this a suitable method for nasal tip reconstruction.

Treatment of symptomatic abnormal skin scars with electrical stimulation

To evaluate the effect of non-invasive biofeedback electrical stimulation on symptomatic abnormal skin scars. Thirty patients with over 140 scars with long-term pain and itch were recruited into the study. Patients monitored the intensity of symptoms (pain and itching) on a numerical rating scale. In addition, a modified Manchester scar scale was used to objectively assess digital photographs of each scar in terms of colour, contour, distortion and texture, while a non-invasive spectrophotometric intracutaneous analysis was used to monitor the scars' physical characteristics. The electrical stimulation device resulted in a clinically and statistically significant (p < 0.05) reduction of symptoms and scar scores. Pain and itch scores were both reduced to a median score of 0 by 2 months, from a baseline of 7 and 6 respectively. Scar scores were reduced from a baseline of 14 to a median score of 11 by 2 months. These results give a preliminary indication of the potential role of non-invasive biofeedback electrical stimulation in the management of chronic scar pain and itch. However, further large scale controlled studies are warranted to elucidate its overall efficacy and mechanistic action. Funding was provided from Fenzian Ltd for this study.

Outcome Measures and Scar Aesthetics in Minimally Invasive Video-Assisted Parathyroidectomy

To compare the scar outcome of video-assisted parathyroidectomy (VAP) with traditional bilateral cervical exploration (BCE) using previously validated scar assessment scales, and to examine the feasibility of introducing VAP into a general otolaryngology-head and neck practice. A retrospective review of medical records from a prospectively obtained database of patients and long-term follow-up of scar analysis. The records of 60 patients undergoing parathyroidectomy were reviewed: 29 patients underwent VAP and 31 patients underwent an open procedure with BCE. The groups were matched for age and sex. A total of 46 patients were followed up to assess scar outcome. The primary outcome was a comparison of patient and observer scar satisfaction between VAP and traditional BCE using validated scar assessment tools: the Patient Scar Assessment Scale and the Manchester Scar Scale. The secondary outcomes were to retrospectively evaluate our results with VAP and to assess the suitability of introducing this technique into a general otolaryngology-head and neck practice. The average scar length in the VAP group was 1.7 cm, and the average scar length in the BCE group was 4.3 cm. The patients in the BCE group scored higher than the patients in the VAP group on the Manchester Scar Scale (P < .01) and on the Patient and Observer Scar Scales (P = .02), indicating a worse scar outcome. The mean operative time in the VAP group was 41 minutes compared with 115 minutes in the open procedure BCE group. There was no difference between the 2 groups in terms of postoperative complications. Video-assisted parathyroidectomy is a safe and feasible procedure in the setting of a general otolaryngology-head and neck practice, with outcomes and complication rates that are comparable to those of traditional bilateral neck exploration. Both patient and observer analysis demonstrated that VAP was associated with a more favorable scar outcome when compared with BCE.

Skin scar preconceptions must be challenged: Importance of self-perception in skin scarring

Greater objective scar severity and visibility should intuitively cause greater psychosocial distress for patients. Previous research is contradictory and has employed non-validated scar severity measures whilst neglecting patient-rated severity. The aim of this study was to assess the effects of objective and patient-rated scar severity, scar type and location on psychosocial distress. Skin scars were quantitatively assessed on two independent occasions using the 'Manchester Scar Scale' (MSS) - a validated measure. Scars were scored twice independently. Patients also rated their scars (from 'very good' [zero] to 'poor' [four]) and good completed the Derriford Appearance Scale (DAS24) and Dermatology Life Quality Index (DLQI). Eighty-two patients, with an average+/-SD (range) age of 34+/-15 (16-65) years were recruited. Mean psychosocial questionnaire scores were: DAS24 45.5+/-17.8 (15-91); DLQI 7.5+/-6.7 (0-26). Participants had 1.9+/-1.5 (1-8) scars with an MSS score of 31.3+/-24.0 (6.6-162.0) and subjective score of 2.6+/-1.2 (0-4). Correlation between psychosocial distress and objective severity was not significant (DAS24 0.14 p=0.11; DLQI 0.16 p=0.06). Correlation between psychosocial distress and subjective severity was significant (DAS24 0.48 p<0.0001; DLQI 0.46 p<0.0001). Patients with non-visible scars experienced greater psychosocial distress than patients with visible scars (DAS24 9.7 p=0.046; DLQI 4.2 p=0.014). Scar type was unrelated to psychosocial distress. Patient-rated scar severity and scar visibility are correlated with psychosocial distress rather than clinician's objective severity rating or scar type. Although counter-intuitive, results are consistent with research into other disfiguring conditions and patient self-assessment should therefore form an integral part of clinical assessment.

P.312 Surgical treatment of rhinophyma

The incidence of skin cancer, which often affects the facial skin, has risen worldwide. After resecting such facial lesions, plastic reconstruction is necessary in most cases. The paramedian forehead flap (PFF) and the bilobed flap (BF) are commonly used for nasal reconstruction, but whether patients and physicians are satisfied with the esthetics is undetermined? In this study, scar questionnaires (Manchester Scar Scale, Vancouver Scar Scale, and Patient and Observer Scar Assessment Scale) and optical three-dimensional (3D) imaging were used for subjective and objective evaluation of esthetical outcomes after plastic reconstruction of the nose in 30 patients. The distances between landmarks and changes in volume between the treated and both the mirrored, healthy side of the face as well as an untreated, matched control group were measured using the optical (3D) scans. The questionnaires ascertained whether the patient was content with the esthetical outcome of both flaps. In the opinion of the observer, the esthetical outcome of both flaps was sufficient; only a few of the measured distances differed significantly between the patients and the control group. However, the measured volume differences of the donor site of the flap differed significantly between the PFF group and the control group (p = 0.0078). The BF was used for smaller defects, while the PFF was used for major defects. Besides a greater donor-side morbidity for the PFF, both flaps led to esthetically sufficient results and could be used for the reconstruction of the nose depending on the defect size and localization.

Suppressed chemotaxis of burn neutrophils

Composite split-thickness skin grafting (STSG) with acellular dermal matrix (ADM) has been used successfully in burn injuries and trauma, but its use in treating diabetic foot ulcers (DFUs) has not been reported to date. This study investigated the efficacy and safety of composite STSG with ADM in the treatment of DFUs.Fifty-two patients with DFUs were randomized into experimental and control groups. Patients in the experimental group received composite STSG over ADM; the control group received STSG alone. The primary end point was recurrence rate 12 months after grafting. Secondary end points were the healing quality of the grafted site according to Manchester Scar Scale and complete wound closure and complication rates.The number of patients that experienced recurrence was significantly less in the experimental group compared with the control group (4.3% vs 22.7%; p = 0.02). The autografted sites of the experimental group had better appearance and lower Manchester Scar Scale scores (median 9 [interquartile range 8 to 10.25] vs median 11 [interquartile range 10 to 12]; p = 0.006). Rates of complete wound closure by weeks 2, 4, and 8 were similar, as were the rates of complications by post-grafting week 4 (38.5% vs 26.9%; p = 0.38).Composite STSG over an ADM scaffold provides an effective method to treat DFUs, with lower recurrence rates and better physical attributes compared with the traditional STSG method. Complete wound closure and complication rates were comparable between these methods.
