Dose-Dependent Effects of Botulinum Toxin Type A on Prevention of Postoperative Scars in Various Regions in the Body: A Prospective, Double-Blind Randomized Controlled Trial. Aesthetic Plast Surg 2024:10.1007/s00266-024-04351-0. [PMID: 39218835 DOI: 10.1007/s00266-024-04351-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Accepted: 08/23/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Botulinum toxin type A (BTXA) can improve wound healing and reduce scar formation; however, the exact dose required to prevent postoperative scarring across various anatomical sites remains unclear. This study aimed to investigate the effectiveness and optimal concentrations of BTXA for preventing postoperative scarring across various common surgical sites throughout the body. METHODS In this prospective randomized controlled trial, 46 patients with benign skin tumors received injections of 1, 2.5, or 5 U/0.1 mL of BTXA or 0.9% saline immediately following surgical tumor excision on both sides of the incisions. Follow-ups were conducted at 7 days, 15 days, and 1, 3, and 6 months postoperatively. Patient-reported adverse events and standardized digital photographs were collected. Scar formation was assessed using the modified Stony Brook Scar Evaluation Scale (mSBSES). RESULTS All 46 patients completed the trial without severe complications. The mSBSES scores were higher in the experimental groups at all follow-ups. The 5 U/0.1 mL BTXA dose group demonstrated optimal scar prevention at all high-risk sites for scar hyperplasia. No significant difference was observed between the 2.5 U/0.1 mL and 5 U/0.1 mL doses for intermediate-risk sites, while 1 U/0.1 mL dose was sufficient for low-risk sites. Overall, 86.5% of patients were satisfied with their treatments, with 16.3% being very satisfied. CONCLUSIONS Early postoperative BTXA injection can reduce or prevent hypertrophic scarring, with optimal doses ranging from 1 to 5 U/0.1 mL depending on the surgical site, supporting broader clinical application of BTXA. The effectiveness of different concentrations of botulinum toxin type A (BTXA) in preventing postoperative scarring was compared, expanding the scope of previous research, which focused only on the head, face, and neck regions, to include the trunk and extremity areas. Different optimal injection strategies were determined based on different surgical sites and their risks of developing hypertrophic scars. The study demonstrates that BTXA not only reduces scar formation but also enhances patient satisfaction and reduces postoperative itching and pain, contributing to overall better postoperative outcomes. By establishing the efficacy and optimal dosing of BTXA for various surgical sites, this research supports the potential for broader clinical application of BTXA in aesthetic and reconstructive surgeries.

Abstract
Background Face plays the most crucial part in defining personality and anything that hampers the facial esthetics foists a great amount of psychological impact. Hence, it is extremely important to manage the facial injuries efficiently and consider all the three elements of recovery, i.e., psychological, medical and esthetics. Purpose-To evaluate the efficacy of silicone gel in healing of lacerated wounds on face. Materials and methods A sample size of 44 patients in each group undergoing suturing of contused lacerated wound (CLW) was calculated with P-67, q-52 and l-10 Using Formula, N = 4pq/l2 using Statistical Package for Social Sciences (SPSS) software version 23. Patients were divided into two groups, Group A and Group B where Group A was study group who applied silicone over sutured wounds, while Group B was control group who did not applied any gel. Results In silicone group, a significant difference was observed between 7th day and 30th, 60th, 90th and 120th day in healing scores, while in non-silicone group, no significant difference was observed at the initial period. However, difference started to appear from 90th day and continued till 120th day. Conclusion Silicone gel has considerable effect in healing of wound and prevention of unesthetic scarring when it is applied immediately from the day of suture removal and continued till 3 months.

Abstract
Although skin scarring is considered by some to be a minor, unavoidable consequence in response to skin injury, for many patients, cosmetically unsightly scars may cause uncomfortable symptoms and loss of function plus significant psycho-social distress. Despite their high prevalence and commonality, defining skin scars and their optimal management has proven problematic. Therefore, a literature search to assess the current evidence-base for scarring treatment options was conducted, and only those deemed Levels of Evidence 1 or 2 were included. Understanding the spectrum of skin scarring in the first instance is imperative, and is mainly comprised of four distinct endotypes; Stretched (flat), Contracted, Atrophic, and Raised for which the acronym S.C.A.R. may be used. Traditionally, scar assessment and response to therapy has employed the use of subjective scar scales, although these are now being superseded by non-invasive, objective and quantitative measurement devices. Treatment options will vary depending on the specific scar endotype, but fall under one of 3 main categories: (1) Leave alone, (2) Non-invasive, (3) Invasive management. Non-invasive (mostly topical) management of skin scarring remains the most accessible, as many formulations are over-the-counter, and include silicone-based, onion extract-based, and green tea-based, however out of the 52 studies identified, only 28 had statistically significant positive outcomes. Invasive treatment options includes intralesional injections with steroids, 5-FU, PDT, and laser with surgical scar excision as a last resort especially in keloid scar management unless combined with an appropriate adjuvant therapy. In summary, scar management is a rapidly changing field with an unmet need to date for a structured and validated approach.

Abstract
This randomized, double-blind, and sham device-controlled trial aimed to evaluate the efficacy and safety of home-based photobiomodulation therapy using an 830-nm light-emitting diode (LED)-based device for the prevention of and pain relief from thyroidectomy scars. Participants were randomized to receive photobiomodulation therapy using an LED device or a sham device without an LED from 1 week postoperatively for 4 weeks. Scars were assessed using satisfaction scores, the numeric rating scale (NRS) score for pain, Global Assessment Scale (GAS), and Vancouver Scar Scale (VSS) scores. The scars were also assessed using a three-dimensional (3D) skin imaging device to detect color, height, pigmentation, and vascularity. Assessments were performed at the 1-, 3-, and 6-month follow-ups. Forty-three patients completed this trial with 21 patients in the treatment group and 22 patients in the control group. The treatment group showed significantly higher patient satisfaction and GAS scores and lower NRS and VSS scores than the control group at 6 months. Improvements in color variation, height, pigmentation, and vascularity at 6 months were greater in the treatment group than in the control group, although the differences were not significant. In conclusion, early application of 830-nm LED-based photobiomodulation treatment significantly prevents hypertrophic scar formation and reduces postoperative pain without noticeable adverse effects.

Abstract
Silicones, more specifically those of the polydimethylsiloxane type, have been widely used in the pharmaceutical industry for decades, particularly in topical applications. In the dermatological field, in addition to provide undeniable textural and sensory benefits, they can play important functions in the physicochemical properties, stability and biopharmaceutical behavior of these formulations. However, despite the notable advances that can be attributed to the family of silicones, the reputation of these compounds is quite bad. Indeed, silicones, even if they derive from sand, are synthetic compounds. Moreover, they are not biodegradable. They flow into our wastewater and oceans, accumulating in the fauna and flora. This obviously raises many concerns in the common imagination. Do silicones represent a danger for our environment? Should the human species worry about long term toxic effects? Are the claimed benefits really that important? After exploring the various applications of silicone excipients in topical dermatological formulations with a special focus on recent advances which open breathtaking prospects for dermatological applications, this paper shed light on the specific challenges involved in preparation of silicone-based drug as well as, the in vivo behavior of these polymers, the toxicological and environmental risks associated with their application.

The use of fluid silicone gels in the prevention and treatment of hypertrophic scars: a systematic review and meta-analysis. Burns 2022; 48:491-509. [PMID: 35367089 DOI: 10.1016/j.burns.2022.03.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 02/04/2022] [Accepted: 03/12/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Silicone products, either as a sheet or in fluid form, are universally considered as the first line therapy in the prevention and treatment of hypertrophic scars and keloids. However, the study results have been questioned by different authors and there has never been a large systematic synopsis published on the efficacy of fluid silicone gels. This systematic review aims to elucidate the available evidence of the results obtained by fluid silicone gels and present a complete and comprehensive overview of the available literature as well as a meta-analysis of the pooled data. METHODS A systematic search for articles concerning the use of silicone gel in the treatment and prevention of scars was performed on 3 different databases (Pubmed, Embase and Cochrane library) according to the PRISMA statement. Only RCT's were included. Qualitative assessment was done by 2 separate reviewers using the Cochrane risk of bias (RoB 2) assessment tool. Revman 5.4.1 software was used for meta-analysis. RESULTS The search yielded 507 articles. Two articles were identified through other sources. After deduplication and removal of ineligible records, 340 records were screened on title and abstract. Full text screening was done for 23 articles and ultimately 18 articles were included. A meta-analysis comparing fluid silicone gel to no treatment or placebo gels was conducted. CONCLUSION Studies on the effects of liquid silicone gels on hypertrophic scars are numerous and this systematic review shows that the use of liquid silicone gels is associated with both a prophylactic and a curative effect on scars. However, a considerable amount of the available 'high evidence' trials are at a high risk for bias and it is uncertain whether or not the effects of silicone gels are comparable to silicone sheets and if the additional components present in many silicone gels are partially responsible for their scar improving capacity.

Prospective, Randomized, Double-Blind, Placebo-Controlled Study on Efficacy of Copaiba Oil in Silicone-Based Gel to Reduce Scar Formation. Dermatol Ther (Heidelb) 2021; 11:2195-2205. [PMID: 34687435 PMCID: PMC8611146 DOI: 10.1007/s13555-021-00634-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 10/13/2021] [Indexed: 11/25/2022] Open
Abstract
Introduction Scars are the end result of a biologic and natural process of wound repair after injury, surgery, acne, illness, burns, and infection. When skin is damaged, a fast and coordinated body response is triggered by four highly integrated and overlapping phases including homeostasis, inflammation, proliferation, and tissue remodeling. Healing of a skin wound may result in an abnormal scar if the balance among these four phases is lost during the healing process. Various topical treatments have been used for their ability to reduce unsightly scar formation. Recently, studies have shown improvement in scar appearance after treating with silicone gels containing natural herbal ingredients. The aim of this study is to evaluate the efficacy of a novel silicone-based gel containing copaiba oil (Copaderm) for prevention and/or appearance reduction of different types of abnormal scars. Methods This study was designed as a prospective, randomized, double-blind, placebo-controlled trial involving 42 patients with abnormal scars, divided into two groups. Each group received either a topical scar formulation consisting of copaiba oil in silicone gel or a placebo gel twice a day for 84 days. Assessments of the scars were performed at 0, 28, and 84 days following the onset of topical application using three methods: a clinical assessment using the Manchester Scar Scale, a photographic assessment to establish before and after treatment improvements, and at the end of the study period, patients completed a final satisfaction questionnaire. Results Of the original 42 patients, 32 completed the evaluation. There was a significant difference with respect to the overall score of the Manchester Scar Scale between the two groups from baseline to 84 days (P < 0.05). All patients with copaiba oil in silicone gel achieved improvement of their scars, based on overall score at 84 days. A visible scar reduction was observed with photographic assessment. Eighty-nine percent of subjects (n = 16) with copaiba oil in silicone gel rated as being satisfied or very satisfied after 84 days of treatment. Conclusion Our findings support the hypothesis that copaiba oil in silicone-derivative gel was able obtain significant improvement in color, contour, distortion, and texture for different types of scar through the Manchester Scar Scale analysis. These findings contribute to reducing abnormal scar formation during the healing process.

CD39 + Fibroblasts Enhance Myofibroblast Activation by Promoting IL-11 Secretion in Hypertrophic Scars. J Invest Dermatol 2021; 142:1065-1076.e19.

Abstract
Fibroblasts (Fbs) are critical to hypertrophic scar (HTS) formation and were recently shown to be highly heterogeneous. However, Fb heterogeneity in HTSs has not been fully elucidated. In this study, we observed an increased fraction of CD39+ Fbs in HTS after screening four Fb subtypes (CD26+, CD36+, FAP+, and CD39+). CD39+ Fbs, enriched in the upper dermis, were positively correlated with scar severity. The transcriptional analysis of CD39+ and CD39- Fbs sorted from HTS revealed that IL-11 was more highly expressed in CD39+ Fbs. We then showed that IL-11 was upregulated in HTSs and that its expression was induced by TGFβ1 in vitro. TGFβ1 also stimulated the expression of CD39 at the transcriptional and protein levels, mediating the maintenance of the CD39+ phenotype. Furthermore, IL-11 facilitated myofibroblast activation and extracellular matrix production in both CD39+ and CD39- Fbs. Interestingly, CD39+ Fbs secreted more IL-11 on TGFβ1 treatment and were less responsive to IL-11 than CD39- Fbs. Notably, a CD39 inhibitor effectively reduced stretch-induced scar formation and attenuated bleomycin-induced skin fibrosis, suggesting an antiscarring approach by targeting CD39+ Fbs.

PLoS One 2021; 16:e0249961.

Abstract
Patients with repaired unilateral cleft lip with palate (UCLP) often show dysmorphology and distorted facial motion clinically, which can cause psychological issues. However, no report has clarified the details concerning distorted facial motion and the corresponding possible causative factors. In this study, we hypothesized that the physical properties of the scar and surrounding facial soft tissue might affect facial displacement while smiling in patients with UCLP (Cleft group). We thus examined the three-dimensional (3D) facial displacement while smiling in the Cleft and Control groups in order to determine whether or not the physical properties of facial soft tissues differ between the Cleft and Control groups and to examine the relationship between the physical properties of facial soft tissues on 3D facial displacement while smiling. Three-dimensional images at rest and while smiling as well as the facial physical properties (e.g. viscoelasticity) of both groups were recorded. Differences in terms of physical properties and facial displacement while smiling between the two groups were examined. To examine the relationship between facial surface displacement while smiling and physical properties, a canonical correlation analysis (CCA) was conducted. As a result, three typical abnormal features of smiling in the Cleft group compared with the Control group were noted: less upward and backward displacement on the scar area, downward movement of the lower lip, and a greater asymmetric displacement, including greater lateral displacement of the subalar on the cleft side while smiling and greater alar backward displacement on the non-cleft side. The Cleft group also showed greater elastic modulus at the upper lip on the cleft side, suggesting hardened soft tissue at the scar. The CCA showed that this hard scar significantly affected facial displacement, inducing less upward and backward displacement on the scar area and downward movement of the lower lip in patients with UCLP (correlation coefficient = 0.82, p = 0.04); however, there was no significant relationship between greater nasal alar lateral movement and physical properties of the skin at the scar. Based on these results, personalizing treatment options for dysfunction in facial expression generation may require quantification of the 3D facial morphology and physical properties of facial soft tissues.

Abstract
Scars are the normal outcome of wound repair and involve a co-ordinated inflammatory and fibrotic process. When a scar does not resolve, uncontrolled chronic inflammation can persist and elicits excessive scarring that leads to a range of abnormal phenotypes such as hypertrophic and keloid scars. These pathologies result in significant impairment of quality of life over a long period of time. Existing treatment options are generally unsatisfactory, and there is mounting interest in innovative cell-based therapies. Despite the interest in mesenchymal stem cells (MSCs), there is yet to be a human clinical trial that investigates the potential of MSCs in treating abnormal scarring. A synthesis of existing evidence of animal studies may therefore provide insight into the barriers to human application. The aim of this PRISMA systematic review was to evaluate the effectiveness of MSC transplantation in the treatment of hypertrophic and keloid scars in in vivo models. A total of 11 case-control studies were identified that treated a total of 156 subjects with MSCs or MSC-conditioned media. Ten studies assessed hypertrophic scars, and one looked at keloid scars. All studies evaluated scars in terms of macroscopic and histological appearances and most incorporated immunohistochemistry. The included studies all found improvements in the above outcomes with MSC or MSC-conditioned media without complications. The studies reviewed support a role for MSC therapy in treating scars that needs further exploration. The transferability of these findings to humans is limited by factors such as the reliability and validity of the disease model, the need to identify the optimal MSC cell source, and the outcome measures employed.

Abstract
This study aimed to investigate the side effects of silicone gel sheet (Lady Care®) and evaluate its prophylactic efficacy in preventing abnormal scarring. Sixty women who underwent caesarean section were recruited from September 2016 to September 2017 in this prospective study. Lady Care® was applied from the 2nd to the 6th postoperative months. Side effects of Lady Care® were evaluated through medical examinations and questionnaires. A plastic surgeon diagnosed abnormal scarring. Pruritus was diagnosed in 25 (47.2%) patients; folliculitis, four (7.5%); dry skin, four (7.5%); contact dermatitis, three (5.7%); wound infection, two (3.8%); and epidermolysis, one (1.9%), albeit with mild severity. Following Lady Care® application, no abnormal scarring and mild hypertrophic scarring was observed in 32 (64.0%) and 18 (36.0%) patients respectively. Of seven patients with pre-existing hypertrophic scars, only two showed hypertrophic scarring after Lady Care® application. Our findings support the safety and prophylactic efficacy of Lady Care®.Impact StatementWhat is already known on this subject? The incidence of abnormal scarring, i.e. keloid or hypertrophic scar formation after caesarean section (CS) is reported to be ∼41%. Abnormal or excessive scar formation can lead to functional limitations, pruritus, pain and cosmetic issues. Studies have also shown a prophylactic effect of the application of silicone materials against the development of hypertrophic and keloid scars, though prohibitive cost and lack of adhesiveness of such gel sheets are known factors limiting their usage.What the results of this study add? The new silicone gel sheet 'Lady Care®' has strong adhesive properties and is consequently not easily peeled off. Furthermore, it is easy to use and economically efficient.What the implications are of these findings for clinical practice and/or further research? This is the first clinical trial on the application of Lady Care® silicone gel sheet for the prevention of CS scarring. Our findings support the safety and prophylactic efficacy of Lady Care®.

Abstract
Background Hypertrophic scars and keloids are postsurgery problems. Some studies showed that onion extract and aloe vera might be beneficial for postoperative scars. However, few of the randomized clinical trials were investigated. Aims To compare the efficacy of silicone gel containing onion extract and aloe vera (SGOA) to silicone gel sheets (SGS) to prevent postoperative hypertrophic scars and keloids. Methods The prospective randomized assessor‐blind controlled trial was conducted with 40 patients who had undergone surgery. The patients were divided into two groups: one treated with SGOA, the other with SGS. The patients were evaluated after 1, 2, and 3 months. The objective assessment was to determine the incidences of scarring, erythema, and melanin values using Mexameter, and pliability through Cutometer. The subjective assessment consisted of the patient and observer scar assessment scale (POSAS) and patient satisfaction. Results After the 12‐week follow‐up, there was no statistically significant difference in the scarring incidence rate of both groups. There were no statistical differences in the POSAS score, erythema, and melanin value between both groups. Using objective assessment, pliability in the SGOA group was statistically significantly higher compared to the SGS group. Pain and itchiness significantly decreased in both groups. No adverse effects were reported in either group. Conclusion Silicone gel containing onion extract and aloe vera is effective as SGS for postoperative scar prevention.

Med J Islam Repub Iran 2020; 34:146. [PMID: 33437742 PMCID: PMC7787045 DOI: 10.34171/mjiri.34.146] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Indexed: 11/24/2022] Open
Abstract
Background: Wound healing is a process that has three overlapping inflammatory, proliferative, and reconstruction phases. Silicone gel and Contractubex (onion extract gel) are two main topical agents used for the prevention and treatment of hypertrophic scars. This clinical trial study aimed to evaluate the efficacy and safety of onion extract and silicone gel on hypertrophic scars of the upper extremity and compare it to non-treated patients.
Methods: This randomized, double-blind, parallel, clinical trial was done on 120 male patients who had undergone upper extremity sharp injury repair. Patients were assigned to three groups, i.e., Silicone gel (Kelo-cortTM; WA, USA) (group 1; 40 patients), Onion extract (ContractubexTM, Merz Pharma, Frankfurt, Germany) gel (group 2; 40 patients), and No Intervention (group 3; 40 patients), using drawing sealed envelopes and a computer-based table of randomization. Data were recorded using the Vancouver scale in each visit by two surgeons who were blinded to the study groups. IBM SPSS Statistics for Windows, Version 22.0. (Armonk, NY: IBM Corp). Data were compared using the ANOVA test. A P-value of less than 0.05 was considered statistically significant.
Results: Vascularity (p=0.200), pliability (p=0.058), pigmentation (p=0.701), and height (p=0.438) as subjective scar parameters were approximately similar in post-upper extremity sharp injury wound hypertrophic scar among the three groups.
Conclusion: Vascularity, pliability, pigmentation and height, as subjective scar parameters, were not statistically different in post-upper extremity sharp injury wound hypertrophic scar among the groups. Even though onion extract gel and Silicone gel show preventive effects in the literature, especially in burns wounds, further studies are recommended to be conducted to prove the topical effects of above-mentioned gels in patients.

Abstract
BACKGROUND There is an increasing number of over-the-counter topical products that are said to prevent pathologic scar formation and improve scar cosmesis. However, robust clinical data are lacking to substantiate these claims and to guide selection of topical products. OBJECTIVE To determine the effectiveness of topical scar management products, including silicone gel, Allium cepa onion extract, vitamin E, trolamine, and microporous tape. METHODS AND MATERIALS A PubMed search (2005-2019) was performed to identify studies of topical scar management products. Randomized controlled trials (RCTs), quasi-RCTs, meta-analyses, and controlled clinical trials were included for analysis. RESULTS A total of 34 trials were included in this study. Of the 16 trials investigating silicone gel sheets, numerous high-quality RCTs found that silicone gel sheets and silicone gels significantly improved scar outcomes. Only a limited number of studies supported the effectiveness of onion extract, vitamin E, trolamine, and microporous tape products. CONCLUSION Silicone gel products are an effective noninvasive treatment to prevent formation of pathologic scars and improve mature scars. Further high-quality studies are needed to elucidate the long-term effectiveness of these therapies.

Abstract
Background: Cobblestoning is the most common complication of minipunch grafting.Objective: To assess the value of silicone gel application following minipunch grafting and the histopathological and immunohistochemical changes in cases with cobblestoning.Methods: Minipunch grafting was performed in two similar vitiligo lesions in 27 cases with stable vitiligo. After healing, silicone gel was applied twice daily on one lesion while zinc oxide ointment was applied to the other lesion serving as a control. Four biopsies were taken from each case; normal, vitiliginous skin before treatment and the two treated lesions 3 months after therapy, for histopathology and immunohistochemical staining for MMP9 & tenascin-C.Results: Repigmentation occurred in 19 cases (70.7%). The number of lesions showing excellent and good response was significantly higher on the silicone gel side (p < .001). In 20 cases, cobblestoning either occurred or was absent on both sides. Histopathologically, cobblestoning was similar to hypertrophic scarring. Both markers were elevated after therapy on both sides with no significant difference in percentage change between lesions showing positive and negative cobblestoning.Conclusion: Silicone gel application after minigrating improved the final response with no significant effect on the occurrence of cobblestoning. Cobblestoning resembled hypertrophic scarring histopathologically.

Abstract
To assess the efficacy of topical silicone gel in the management of scars, we conducted this meta-analysis. The systematic search was performed on PubMed, Web of Science and Embase, and six randomised controlled trials with a total of 375 patients were involved. The outcome data of Vancouver Scar Scale were extracted from the studies and their effect sizes were calculated using Review Manager 5.3. As a result, topical silicone gel significantly reduced pigmentation, height, and pliability scores postoperatively compared with placebos or no treatment (Pigmentation: standard mean difference [SMD] = -0.55 [-0.83 to -0.26], P = .0002; Height: SMD = -0.73 [-1.02 to -0.44], P < .00001; Pliability: SMD = -0.49 [-0.95 to -0.03], P = .04). Topical silicone gel and silicone gel sheet were comparably effective (P > .05). The performance of topical silicone gel and other non-silicone topical treatment was also similar (P > .05). In summary, topical silicone gel was effective in post-operative scar prevention.

Abstract
Supplemental Digital Content is available in the text. Background: With the increased focus on the neck and chin in the era of selfies and social media, neck contouring continues to be an in-demand procedure. Full correction of the neck typically requires both submental and postauricular incisions, but the postauricular incisions can be unsightly and painful. This article introduces a viable alternative for the patient. Methods: A case series of appropriate candidates undergoing a novel neck lift technique (the single incision minimally invasive neck lift) is described. Participants include men and women with an age range of 30–70. The surgical technique incorporates shifting of the typical submental incision used in a full neck lift to a cervicomental incision, and when accompanied by wide undermining, the postauricular incisions are avoided entirely. Results: Among the 20 patients in this case study, photographs show that it is possible to achieve results commonly associated with a full neck lift but without the postauricular incisions typically associated with a full neck lift. Conclusions: The single incision minimally invasive neck lift allows the surgeon to offer an effective procedure for appropriate candidates who want to treat excess fat, a sagging platysma muscle and loose, misplaced skin in the submental region without postauricular incisions typically utilized in a traditional full neck lift.

Abstract
Upper motor neuron injuries that occur in cases such as cerebral palsy, cerebrovascular accidents, and traumatic brain injury often have resulting upper extremity deformity and dysfunction. Multiple surgical options are available to improve upper extremity positioning, and, in some cases, motor control. Postoperative therapeutic management is imperative to assist the patient/caregiver in maximizing potential functional gains. This article provides an overview of postoperative guidelines for commonly performed surgeries to manage upper extremity dysfunction caused by spasticity and discusses acute management as well as therapeutic techniques for functional training and improved motor control.

Abstract
BACKGROUND Silicone sheet is commonly used for scar management but hard to apply to irregular surfaces or mobile areas, and difficult to conceal. On the contrary, silicone gel is easy to apply and nearly unnoticeable. Therefore, we conducted this study to compare their effectiveness. METHODS Patients undergoing horizontal cesarean section were included. Surgical wounds were divided into 2 halves. Patients randomly applied silicone sheets and silicone gel on either side of their wounds for 3 months. The wounds were assessed at 1, 3, 6, and 12 months after surgery. We used the Vancouver Scar Scale (VSS) for an objective evaluation and the visual analog scale (VAS) for a subjective evaluation. RESULTS There was no statistical significance between the silicone sheet and silicone gel groups with respect to VSS score. The silicone sheet group showed a statistically significant higher VAS score for itch at 1 month follow-up (1.18 ± 2.04 vs 0.35 ± 0.85, P = .01). However, the difference was less than 1 on a scale of 10, so it might not be clinically meaningful. CONCLUSION Silicone sheet group showed statistically significant worse VAS score in terms of itch. However, the difference was too small to be clinically meaningful.

Abstract
Background Keloid is an abnormal growth of scar at the site of skin injury, which usually does not regress. It proliferates beyond the original scar. The ear keloid usually develops after piercing injury to wear ornaments. A patient usually asks for removal of keloid, as it is aesthetically unpleasant. Patient may sometimes complain of itching and pain. Aim The study was conducted to analyze results following excision of keloid with its tract and topical silicone gel as the postsurgical adjuvant. Materials and Methods Ear keloids measuring less than 0.5cm or more than 5cm in maximum dimension were excluded from the study. Nonpiercing causes such as burns, trauma, and recurrent keloid were excluded from the study. The study was carried out on 22 patients who had keloid because of piercing injury, including 4 cases with both ear keloids. Of 26 ear keloids, 19 had the tract or connecting tissue. The lesion was excised under anesthesia using magnification. For all the operated cases, topical liquid silicone gel was used as postsurgical adjuvant therapy. The method of application of topical silicone gel was taught to each patient and was considered significant. Result The magnification helped in identification of tract in 73% of the cases in this study. Twenty patients had successfully responded to proposed treatment, and two patients developed recurrence while using topical silicone gel as the adjuvant. These two patients were managed with conventional triamcinolone injection. Conclusion The topical silicone gel as postsurgical adjuvant therapy avoided the use of painful postsurgical injection or radiotherapy for the 1-3cm primary ear keloids. The advantages of magnification were better clearance of keloid tissue, easier identification of tract and removal of keloid pseudopods, meticulous suturing, and comfortable elevation of a small local flap.

Abstract
BACKGROUND Scars represent the visible sequelae of trauma, injury, burn, or surgery. They may induce distress in the patient because of their aesthetically unpleasant appearance, especially if they are excessively raised, depressed, wide, or erythematous. They may also cause the patient symptoms of pain, tightness, and pruritus. Numerous products are marketed for scar prevention or improvement, but their efficacy is unclear. METHODS A literature review of high-level studies analyzing methods to prevent or improve hypertrophic scars, keloids, and striae distensae was performed. The evidence from these articles was analyzed to generate recommendations. Each intervention's effectiveness at preventing or reducing scars was rated as none, low, or high, depending on the strength of the evidence for that intervention. RESULTS For the prevention of hypertrophic scars, silicone, tension reduction, and wound edge eversion seem to have high efficacy, whereas onion extract, pulsed-dye laser, pressure garments, and scar massage have low efficacy. For the treatment of existing hypertrophic scars, silicone, pulsed-dye laser, CO2 laser, corticosteroids, 5-fluorouracil, bleomycin, and scar massage have high efficacy, whereas onion extract and fat grafting seem to have low efficacy. For keloid scars, effective adjuncts to excision include corticosteroids, mitomycin C, bleomycin, and radiation therapy. No intervention seems to have significant efficacy in the prevention or treatment of striae distensae. CONCLUSION Although scars can never be completely eliminated in an adult, this article presents the most commonly used, evidence-based methods to improve the quality and symptoms of hypertrophic scars, as well as keloid scars and striae distensae.
