    Autografting with split-thickness skin grafts (STSG) remains an essential procedure in burn and reconstructive surgery. The process of harvesting STSG, however, leaves behind a donor site, an exposed area of partial-thickness dermis left to heal by secondary intention. There has yet to be a consensus amongst surgeons regarding optimal management of the donor site. The ideal donor site dressing is one that allows for expeditious healing while minimizing pain and infection. Despite numerous studies demonstrating the superiority of moist wound healing, many surgeons continue to treat STSG donor sites dry, with petroleum-based gauze. In this study, two burn centers performed a retrospective review of burn patients whose STSG donor sites were treated with either Xeroform® or Mepilex® Ag dressings. Infections were documented and in a subgroup analysis of patients, postoperative pain scores were noted and total opiate usage during hospitalization was calculated. Analysis revealed an overall infection rate of 1.2% in the Mepilex® Ag group and 11.4% in the Xeroform® group (p<0.0001). Patients with Xeroform® donor site dressings had increased odds of donor site infection (OR=10.8, p=0.002). In subgroup analysis, there were no significant differences in maximum pain scores between Mepilex® Ag and Xeroform® groups, nor were there differences in opiate usage. STSG donor sites dressed with silver foam dressings have a lower rate of donor site infection relative to those dressed with petroleum-based gauze. Moist donor site dressings such as foam dressings (including Mepilex® Ag) should be the standard of care in STSG donor site wound care.
    La greffes de peau mince (GPM) demeure une procédure essentielle dans la chirurgie de brûlure et de reconstruction. La zone donneuse de greffe (ZDG) représente une perte de substance cutanée superficielle, cicatrisant spontanément. Il n’y a pas de consensus concernant la prise en charge optimale de la ZDG. Le pansement idéal de la ZDG doit promouvoir la cicatrisation et réduire la douleur ainsi que le risque infectieux. Malgré les nombreuses publications montrant l’intérêt d’un environnement humide pour la cicatrisation, de nombreux chirurgiens réalisent des pansements secs vaselinés. Cette étude rétrospective effectuée dans 2 CTB compare les pansements de ZDG réalisés au Xéroform® ou au Mepilex Ag®. Les infections ont été documentées et, dans un sous-groupe, les scores de douleur et la consommation d’opiacés au long de l’hospitalisation ont été notés. Les taux d’infection sont de 1,2% dans le groupe Mepilex Ag® et 11,4% avec Xéroform® (p<0,0001). Le risque d’infection de la ZDG est augmenté (OR 10,8 ; p = 0,002) en cas d’utilisation de Xéroform®. Il n’y avait pas de différence de douleur et de consommation d’opiacés entre les 2 groupes. Les ZDG recouvertes d’un pansement hydrocellulaire imprégné d’argent s’infectent moins que celles traitées avec une gaze imprégnée de vaseline. L’utilisation sur les ZDG d’un pansement humide comme une mousse hydrocellulaire (par exemple Mepilex Ag®) devrait devenir la norme.

    在美国,获得性阴茎埋藏畸形是一种越来越常见的疾病。掩埋阴茎畸形的治疗是通过从脂膜和耻骨前区域去除浸软的皮肤和皮下组织来完成的。并更换裸露的阴茎皮肤。如果局部组织推进不足以覆盖缺损,可能需要进行皮肤移植。虽然大腿前部是常用的,这产生了第二个缺陷。在这里,我们描述了2例从膜中收获的厚度分裂的皮肤移植物,以覆盖掩埋的阴茎畸形。
    确认了两名阴茎隐埋畸形患者。裸露的耻骨上组织升高。使用较差的牵引力,收获厚薄的皮肤移植物并将其放置在阴茎轴上。切除剩余的多余组织。
    一名患者出现真菌皮疹,经局部治疗后缓解。另一名患者患有血肿,需要手术撤离。两个病人都没有其他并发症,两者都有超过95%的厚度分裂的皮肤移植物。
    这些病例证明了将膜皮移植成功用于隐埋阴茎畸形矫正。该供体位点避免了第二缺陷的产生。正如这里所证明的,移植物是一个持久的选择,即使在局部感染和血肿的情况下。
    UNASSIGNED: In the United States, acquired buried penis deformity is an increasingly more common condition. Management of the buried penis deformity is accomplished with removal of macerated skin and subcutaneous tissue from the panniculus and prepubic region, and replacement of denuded penile skin. If local tissue advancement is insufficient to cover the defect, a skin graft may be required. Though the anterior thigh is commonly used, this creates a second defect. Here we describe 2 cases of split-thickness skin grafts harvested from the panniculus to cover buried penis deformities.
    UNASSIGNED: Two patients with a buried penis deformity were identified. The denuded suprapubic tissue was elevated. Using inferior traction, split-thickness skin grafts were harvested and placed onto the shaft of the penis. The remaining excess tissue was resected.
    UNASSIGNED: One patient had a fungal rash that resolved with topical treatment. The other patient had a hematoma requiring surgical evacuation. Neither patient had any other complications, and both had over 95% take of the split-thickness skin grafts.
    UNASSIGNED: These cases demonstrate the successful use of pannicular skin grafts for buried penis deformity correction. This donor site avoids creation of a second defect. As demonstrated here, the grafts are a durable option, even in the setting of local infection and hematoma.

    背景:桡骨前臂游离皮瓣(RFFF)是各种重建的主力。尽管RFFF抬高后有多种手术技术可用于供体部位的闭合,最常见的技术是使用分层厚度皮肤移植(STSG)或全厚度皮肤移植(FTSG)进行闭合.闭合可导致前臂和手的伤口并发症和功能以及美学损害。计划的系统评价和荟萃分析的目的是比较与伤口相关的功能相关和美学相关的结果与全厚度皮肤移植物(FTSG)和分裂厚度皮肤移植物(STSG)在radial前臂游离皮瓣(RFFF)供体部位闭合。
    方法:将进行系统评价和荟萃分析。将遵循系统审查和荟萃分析(PRISMA)指南的首选报告项目。电子数据库和平台(PubMed,Embase,Scopus,WebofScience,Cochrane中央对照试验登记册(中央),中国国家知识基础设施(CNKI)和临床试验注册(ClinicalTrials.gov,德国临床试验注册,ISRCTN注册表,国际临床试验注册平台)将使用预定义的搜索词进行搜索,直到2024年1月15日。重新搜索将在审查发表前12个月内进行。符合条件的研究应报告在提高RFFF和缺损闭合后供体部位并发症的发生。包括的闭合技术是使用全厚度皮肤移植物和分裂厚度皮肤移植物的技术。排除的闭合技术是不使用皮肤移植物的初次伤口闭合。结果被认为是受伤的-,功能-,和美学相关。将纳入的研究是随机对照试验(RCTs)以及前瞻性和回顾性比较队列研究。病例对照研究,没有对照组的研究,动物研究和尸体研究将被排除在外。每个研究将由两名审阅者以盲法方式进行筛选。第三位审稿人解决差异。将使用ROBINS-I和RoB2工具评估原始研究中的偏倚风险。使用ReviewManager(RevMan)5.4.1完成数据合成。如果合适,将进行荟萃分析。研究之间的变异性将使用I2指数进行评估。如有必要,将使用R。结果的证据质量最终将使用建议分级评估来评估,开发和评估(等级)方法。
    结论:这项研究的发现可能有助于我们了解两种闭合技术的并发症发生率,并可能对未来RFFF供体部位管理指南的制定具有重要意义。如果可用数据有限,并且有几个问题仍未得到回答,将需要更多的比较研究。
    背景:该协议是根据PRISMA-P协议扩展而开发的,并于2023年9月17日在国际前瞻性系统审查登记册(PROSPERO)注册(注册号CRD42023351903)。
    BACKGROUND: The radial forearm free flap (RFFF) serves as a workhorse for a variety of reconstructions. Although there are a variety of surgical techniques for donor site closure after RFFF raising, the most common techniques are closure using a split-thickness skin graft (STSG) or a full-thickness skin graft (FTSG). The closure can result in wound complications and function and aesthetic compromise of the forearm and hand. The aim of the planned systematic review and meta-analysis is to compare the wound-related, function-related and aesthetics-related outcome associated with full-thickness skin grafts (FTSG) and split-thickness skin grafts (STSG) in radial forearm free flap (RFFF) donor site closure.
    METHODS: A systematic review and meta-analysis will be conducted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines will be followed. Electronic databases and platforms (PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI)) and clinical trial registries (ClinicalTrials.gov, the German Clinical Trials Register, the ISRCTN registry, the International Clinical Trials Registry Platform) will be searched using predefined search terms until 15 January 2024. A rerun of the search will be carried out within 12 months before publication of the review. Eligible studies should report on the occurrence of donor site complications after raising an RFFF and closure of the defect. Included closure techniques are techniques that use full-thickness skin grafts and split-thickness skin grafts. Excluded techniques for closure are primary wound closure without the use of skin graft. Outcomes are considered wound-, functional-, and aesthetics-related. Studies that will be included are randomized controlled trials (RCTs) and prospective and retrospective comparative cohort studies. Case-control studies, studies without a control group, animal studies and cadaveric studies will be excluded. Screening will be performed in a blinded fashion by two reviewers per study. A third reviewer resolves discrepancies. The risk of bias in the original studies will be assessed using the ROBINS-I and RoB 2 tools. Data synthesis will be done using Review Manager (RevMan) 5.4.1. If appropriate, a meta-analysis will be conducted. Between-study variability will be assessed using the I2 index. If necessary, R will be used. The quality of evidence for outcomes will eventually be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
    CONCLUSIONS: This study\'s findings may help us understand both closure techniques\' complication rates and may have important implications for developing future guidelines for RFFF donor site management. If available data is limited and several questions remain unanswered, additional comparative studies will be needed.
    BACKGROUND: The protocol was developed in line with the PRISMA-P extension for protocols and was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 17 September 2023 (registration number CRD42023351903).

    尽管病因不同,急性热烧伤和全厚度(FT)皮肤缺损与类似的治疗挑战有关。当不适合主要或次要关闭时,这些伤口类型的常规护理标准(SoC)治疗是分层厚度皮肤移植(STSG)。这种侵入性手术需要供体皮肤的足够可用性,并且与供体部位的发病率有关。高医疗保健资源使用(HCRU),以及与长期住院有关的费用。因此,可以促进有效愈合和供体皮肤保留的治疗选择已被高度预期。RECELL®自体细胞收获装置有助于制备用于治疗急性热烧伤和FT皮肤缺损的自体皮肤细胞悬浮液(ASCS)。在最初的临床试验中,该方法在急性热烧伤患者中显示出较好的供体皮肤保护益处和与SoCSTSG相当的伤口愈合.这些发现导致2018年美国食品和药物管理局(FDA)批准了RECell的这一适应症。随后的非热FT皮肤伤口的临床评估显示,当与广泛网格的STSG结合使用时,与SoCSTSG相比,提供供体皮肤保护优势和可比的愈合效果。因此,该装置于2023年6月获得FDA批准,用于治疗由创伤性撕脱或手术切除或切除引起的FT皮肤缺损.鉴于已证明RECell±STSG与单独用于烧伤治疗时的STSG具有健康经济优势,谨慎的做法是检查烧伤和FT皮肤缺损治疗途径的相似性,以预测用于FT皮肤缺损时RECell的潜在健康经济优势.本文讨论了两种适应症之间的相似之处,RECell报告的临床结果,以及HCRU和使用该装置可预期的非热FT皮肤缺损的成本效益。
    Despite differing etiologies, acute thermal burn injuries and full-thickness (FT) skin defects are associated with similar therapeutic challenges. When not amenable to primary or secondary closure, the conventional standard of care (SoC) treatment for these wound types is split-thickness skin grafting (STSG). This invasive procedure requires adequate availability of donor skin and is associated with donor site morbidity, high healthcare resource use (HCRU), and costs related to prolonged hospitalization. As such, treatment options that can facilitate effective healing and donor skin sparing have been highly anticipated. The RECELL® Autologous Cell Harvesting Device facilitates preparation of an autologous skin cell suspension (ASCS) for the treatment of acute thermal burns and FT skin defects. In initial clinical trials, the approach showed superior donor skin-sparing benefits and comparable wound healing to SoC STSG among patients with acute thermal burn injuries. These findings led to approval of RECELL for this indication by the US Food and Drug Administration (FDA) in 2018. Subsequent clinical evaluation in non-thermal FT skin wounds showed that RECELL, when used in combination with widely meshed STSG, provides donor skin-sparing advantages and comparable healing outcomes compared with SoC STSG. As a result, the device received FDA approval in June of 2023 for treatment of FT skin defects caused by traumatic avulsion or surgical excision or resection. Given that health economic advantages have been demonstrated for RECELL ± STSG versus STSG alone when used for burn therapy, it is prudent to examine similarities in the burn and FT skin defect treatment pathways to forecast the potential health economic advantages for RECELL when used in FT skin defects. This article discusses the parallels between the two indications, the clinical outcomes reported for RECELL, and the HCRU and cost benefits that may be anticipated with use of the device for non-thermal FT skin defects.

    皮肤移植涉及去除皮肤的一部分并将其用于身体的另一部分。使用移植物的最常见原因之一是烧伤。我们旨在比较Colactive加Ag敷料与凡士林纱布敷料在烧伤患者分层厚度皮肤移植物的供体部位的效果。
    本研究是在Motahari烧伤医院进行的一项随机临床试验(RCT),德黑兰,伊朗1401抽样方法使用Cochran公式和可用的患者进行,因此招募了15人。研究结果是使用研究人员制作的表格收集的。
    恢复的平均持续时间,疼痛的程度和强度,两种Colative+Ag+Ag敷料与凡士林纱布之间的瘙痒量在95%置信水平上具有统计学意义。(P值<0.05)。此外,结果表明,在95%置信水平(P值>0.05)下,两种敷料中伤口留下的平均疤痕量无统计学意义。
    使用合银敷料疼痛较少,在供体区域减少瘙痒,平均恢复时间比凡士林纱布短。使用Colactive加Ag将比凡士林纱布更有效。
    UNASSIGNED: Skin graft involves removing a part of the skin and using it in another part of the body. One of the most common reasons for using a graft is burns. We aimed to compare the effect of Colactive plus Ag dressing with Vaseline gauze dressing in donor sites of split-thickness skin grafts of burned patients.
    UNASSIGNED: The present study was conducted as a randomized clinical trial (RCT) in the Motahari burn Hospital, Tehran, Iran in 1401. The sampling method was done using Cochran\'s formula and available patients so 15 people were enrolled. The findings of the study were collected using a researcher-made form.
    UNASSIGNED: The average duration of recovery, the amount and intensity of pain, and the amount of itching between the two types of Colative plus Ag plus Ag dressing with Vaseline gauze are statistically significant at the 95% confidence level. (P-value<0.05). In addition, the findings showed that the average amount of scar left by the wound in the two types of dressings examined is not statistically significant at the 95% confidence level (P-value > 0.05).
    UNASSIGNED: The use of Colactive silver dressing has less pain, less itching in the donor area, and a shorter average recovery time than Vaseline gauze. The use of the Colactive plus Ag will be more effective than Vaseline gauze.

    童年对社会发展至关重要,物理,和认知功能。儿童的烧伤与成人的烧伤有很大不同,因为他们很难自救。他们的皮肤更敏感,耐热性更低;他们的暴露可能持续更长的时间,加重烧伤。当被忽视时,儿童烧伤引起的严重致残和变形挛缩可导致严重损害。因此,烧伤康复不应由一个人进行,而应由多学科团队进行,以确保所有患者的身体,心理,在孩子住院和出院后,社会要求得到满足。年轻烧伤受害者的治疗需要从事故发生之日起开始并持续数年的多学科方法。为了减少患者创伤后压力的后果,增加功能独立性,需要一个彻底的康复方案。燃烧团队成员的奉献精神,致力于患者的护理,鼓励患者参与和充分参与康复可以对青少年烧伤患者的长期生活质量(QOL)产生影响。我们介绍了一名7岁的女性,她的右大腿外侧表面烧伤。运动处方应彻底定制,以提供最佳的康复成功,考虑到烧伤的程度和身体限制。本病例报告旨在作为有效管理烧伤患者的必要临床知识和治疗干预方法的实用手册。
    Childhood is critical for developing social, physical, and cognitive functioning. Burns in children are very different from burns in adults because it is difficult for them to save themselves. Their skin is more sensitive and less heat-resistant; their exposure may last longer, worsening the burn. When neglected, severe disabling and deforming contractures caused by burns in children can result in substantial impairment. Therefore, burn rehabilitation should not be carried out by one person but rather by a multidisciplinary team to ensure that all of the patients\' physical, psychological, and social requirements are met while the child is in the hospital and after discharge. The treatment of young burn victims requires a multidisciplinary approach that begins the day of the accident and lasts for several years. To reduce the consequences of the patient\'s post-traumatic stress and increase functional independence, a thorough rehabilitation programme is needed. The burn team members\' dedication, commitment to the patient\'s care, and encouragement of patient participation and full engagement in rehabilitation can make a difference to juvenile burn patients\' long-term quality of life (QOL). We present a seven-year-old female who suffered from a superficial burn over the lateral aspect of her right thigh. Exercise prescriptions should be thoroughly customized to provide the best possible success in rehabilitation, considering the degree of burns and physical limitations. This case report is intended to serve as a practical manual for the necessary clinical knowledge and therapy intervention approaches for managing burn patients successfully.

    背景:已发现黑色素瘤患者在接触COVID-19后有更大的不良结局风险,包括死亡。手术后并发症的管理带来了额外的挑战,因为在大流行期间反复住院,可能会增加COVID-19的暴露。我们报告了四例皮瓣,淋巴结扎,和裂层皮肤移植(STSG)成功用于广泛局部切除术(WLE)后躯干和四肢并发症的治疗。这项研究详细介绍了在COVID-19大流行期间的6个月内,躯干和四肢黑色素瘤术后并发症的手术经验。
    方法:我们介绍了4例病例,详细说明了在2月期间对黑色素瘤进行广泛局部切除后发生的并发症的处理至10月2020年。病例1:一名90岁的男子,在非根治性黑色素瘤切除术后,肩部出现伤口裂开和坏死,并在椭圆形形成WLE后用改良的切线到圆方法进行了左右闭合。病例2:一名80岁的男性,他的左上臂黑色素瘤切除,组织病理学未显示出彻底的表现。切除两周后,他接受了WLE和双旋转皮瓣的直接重建。案例3:一名55岁的男子由于WLE而在他的背部经历了大的伤口裂开。他接受了先进的双皮瓣手术。病例4:一名36岁女性,在右小腿WLE和STSG后出现淋巴漏和移植物坏死。进行了微淋巴结扎和re-STSG的组合。手术后一个月,所有伤口都愈合了.术后8个月没有肿瘤复发的临床证据。
    结论:严重并发症(例如,大的伤口裂开,坏死,或淋巴漏)局部广泛切除黑色素瘤后很少见,但必须迅速和适当地管理,特别是在COVID-19大流行期间,由于主要干预措施的并发症而延迟全身癌症治疗,降低了COVID-19感染和肿瘤学结局受损的可能性。
    BACKGROUND: Patients with melanoma have been found to be at greater risk of adverse outcomes including mortality after contacting COVID-19. Management of postsurgical complications presented additional challenges by potentially increasing exposure to COVID-19 through repeated inpatient admissions to hospital during the pandemic. We report four cases for which skin flaps, lymph ligation, and split-thickness skin graft (STSG) were successfully used in the treatment of complications in the trunk and extremities after wide local excision (WLE). This study details the operative experience in management of postsurgical complications for melanoma in the trunk and extremities during a 6-month period at the height of the COVID-19 pandemic.
    METHODS: We present 4 cases detailing management of complications that occurred after wide local excisions performed for melanoma during Feb. to Oct. 2020. Case 1: A 90-year-old man who experienced wound dehiscence and necrosis on the shoulder after non-radical excision for an aggressive melanoma and underwent the side-to-side closure after ellipse formed WLE with modified tangent-to-circle method. Case 2: An 80-year-old man who had undergone excision for melanoma in his left upper arm and histopathology did not show radically. Two weeks after the excision, he underwent a WLE and direct reconstruction with double rotation skin flap. Case 3: A 55-year-old man that experienced a large wound dehiscence on his back due to WLE. He underwent an advanced double skin flap operation. Case 4: A 36-year-old woman who had a lymphorrhea and graft necrosis after WLE and STSG on the right lower leg. A combination of micro lymph ligation and re-STSG was performed. One month after the operation, all wounds had healed. There was no clinical evidence of tumor recurrence after 8 months post procedure.
    CONCLUSIONS: Severe complications (e.g., large wound dehiscence, necrosis, or lymphorrhea) following wide local excision of melanoma are infrequent but must be swiftly and appropriately managed, especially during the COVID-19 pandemic to decrease the likelihood of COVID-19 infection and impaired oncology outcomes from delaying systemic cancer therapy due to the complications in primary interventions.

    病态真皮模板,微血管病,和异常炎症是糖尿病伤口瘢痕愈合和复发率高的三个最关键的原因。在本研究中,甲基丙烯酸酯化的脱细胞细胞外基质的组合(ECMMA,akaEM)基于水凝胶系统的负载铜-表没食子儿茶素没食子酸酯(Cu-EGCG)胶囊被提议制造用于糖尿病伤口治疗的生物打印真皮支架。铜离子作为促进血管生成的生物活性元素,EGCG可以抑制伤口部位的炎症。除上述活动外,EM/Cu-EGCG(E/C)真皮支架还可以提供优化的模板和营养交换空间,以指导ECM的有序沉积和重塑。体外实验表明,E/C水凝胶可以促进血管生成并抑制巨噬细胞向M1促炎表型的极化。在糖尿病大鼠全层皮肤缺损模型中,E/C真皮支架联合裂层皮肤移植可通过促进血管生成和驱动巨噬细胞极化为抗炎M2表型来减轻病理性瘢痕形成。这些可能归因于HIF-1α/血管内皮生长因子途径中血管生成相关基因的支架驱动表达和TNF-α/NF-κB/MMP9途径中炎症相关基因的表达降低。这项研究的结果表明,E/C真皮支架可以作为一种有前途的人造真皮类似物,用于解决糖尿病伤口延迟愈合和溃疡的问题。
    Morbid dermal templates, microangiopathy, and abnormal inflammation are the three most critical reasons for the scarred healing and the high recurrence rate of diabetic wounds. In this present study, a combination of a methacrylated decellularized extracellular matrix (ECMMA, aka EM)-based hydrogel system loaded with copper-epigallocatechin gallate (Cu-EGCG) capsules is proposed to fabricate bio-printed dermal scaffolds for diabetic wound treatment. Copper ions act as a bioactive element for promoting angiogenesis, and EGCG can inhibit inflammation on the wound site. In addition to the above activities, EM/Cu-EGCG (E/C) dermal scaffolds can also provide optimized templates and nutrient exchange space for guiding the orderly deposition and remodeling of ECM. In vitro experiments have shown that the E/C hydrogel can promote angiogenesis and inhibit the polarization of macrophages to the M1 pro-inflammatory phenotype. In the full-thickness skin defect model of diabetic rats, the E/C dermal scaffold combined with split-thickness skin graft transplantation can alleviate pathological scarring via promoting angiogenesis and driving macrophage polarization to the anti-inflammatory M2 phenotype. These may be attributed to the scaffold-actuated expression of angiogenesis-related genes in the HIF-1α/vascular endothelial growth factor pathway and decreased expression of inflammation-related genes in the TNF-α/NF-κB/MMP9 pathway. The results of this study show that the E/C dermal scaffold could serve as a promising artificial dermal analogue for solving the problems of delayed wound healing and reulceration of diabetic wounds.

    背景和目标:压疮是患者常见的医疗负担,特别是那些卧床不起或虚弱的人。由于有限的弹性和头皮的球形形状,枕骨压疮的手术管理提出了独特的挑战。这项研究旨在评估一种新颖的重建方法的有效性和安全性,该方法利用局部移位皮瓣和分层厚度的皮肤移植物以及负压伤口疗法(NPWT)进行枕部压疮治疗。材料和方法:对枕骨压疮患者进行了回顾性分析,这些患者使用局部皮瓣和裂层皮肤移植物结合NPWT进行了混合重建。手术结果,包括皮瓣存活率,嫁接百分比,和并发症,被评估。在NPWT组和常规敷料组之间进行比较分析。结果:与传统敷料组(n=22)相比,NPWT组(n=24)在术后第14天显示出明显更高的平均移植物摄取百分比(98.2%vs.81.2%,p<0.05)。两组皮瓣成活率差异无统计学意义。结论:随着人口老龄化的持续增长,枕骨压疮作为一种重要的医疗条件已经得到了广泛的关注。结合NPWT的创新手术方法为枕部压疮患者提供了有效和安全的治疗选择,有可能将自己确立为管理这一条件的未来黄金标准。
    Background and objectives: Pressure sores are a common medical burden among patients, particularly those who are bedridden or frail. Surgical management of occipital pressure sores poses unique challenges due to limited elasticity and the spherical shape of the scalp. This study aims to evaluate the efficacy and safety of a novel reconstruction method utilizing a local transpositional flap and split-thickness skin graft with negative pressure wound therapy (NPWT) for occipital pressure sore treatment. Material and methods: A retrospective analysis was performed on patients with occipital pressure sores who underwent hybrid reconstructions using a local flap and split-thickness skin graft in conjunction with NPWT. Surgical outcomes, including flap survival rate, graft take percentage, and complications, were assessed. A comparative analysis was performed between the NPWT group and the conventional dressing group. Results: The NPWT group (n = 24) demonstrated a significantly higher mean graft take percentage at postoperative day 14 compared with the conventional dressing group (n = 22) (98.2% vs. 81.2%, p < 0.05). No significant difference in flap survival rate was observed between the two groups. Conclusions: As the aging population continues to grow, occipital pressure sores have gained significant attention as a crucial medical condition. The innovative surgical method incorporating NPWT offers an efficient and safe treatment option for patients with occipital pressure sores, potentially establishing itself as the future gold standard for managing this condition.
