  • 文章类型: Case Reports
    为了应对隆鼻需求的增加,特别是在亚洲人口统计学中,已经见证了从自体材料到合成植入物的转变,如有机硅和膨胀聚四氟乙烯。这些材料会增加感染等并发症的风险,挤压,包膜挛缩,和不满。这项研究的重点是一名48岁患者先前使用硅胶植入物的翻修隆鼻手术,并提出了一种管理植入物胶囊的创新方法。在背侧重建中使用现有的胶囊作为切块软骨移植物的机械和生物支持结构,展示了一种有希望的方法来减轻风险并改善翻修手术的结果。硅胶周围的胶囊具有生物活性,并为软骨移植物的存活和改善愈合过程提供了良好的环境。这种方法倾向于尽量减少解剖,以避免潜在的翻修并发症,如皮肤坏死,纤维化组织,和感染。
    To answer the increased demand for augmentation rhinoplasty, particularly in Asian demographics, a shift from autogenous materials to synthetic implants like silicone and expanded polytetrafluoroethylene has been witnessed. These materials present an increased risk of complications like infection, extrusion, capsular contracture, and dissatisfaction. This study focuses on a case of revision rhinoplasty in a 48-year-old patient with a previous silicone implant and propose an innovative approach in managing the implant capsule. The use of the existing capsule as a mechanical and biological support structure for the diced cartilage graft in dorsal reconstruction showcases a promising method to mitigate risks and improve outcomes in revision surgeries. The capsule around the silicone is biologically active and provides a good environment for the cartilage graft to survive and improve the healing process. This approach tends to minimize the dissection to avoid potential revision complications like skin necrosis, fibrotic tissue, and infections.

    唇裂隆鼻术(CLR)可矫正唇腭裂患者的鼻畸形。然而,在一些国家,如日本,在CLR使用硅胶植入物方面存在限制。虽然历史报道提到了自1980年代以来它们的使用,缺乏长期数据。该病例报告描述了一名53岁的日本女性,患有双侧唇裂和腭裂,30多年前接受了带有硅胶植入物的CLR。植入物钙化,导致鼻背皮肤硬化和变薄,引起人们对挤压的担忧。为了防止潜在的挤压,移除植入物,并用自体第七肋软骨移植物代替.各种嫁接技术被用于基础支持,背侧增强,和鼻尖细化。术后评估结果良好,无并发症。此病例强调了使用硅胶植入物进行CLR后长期随访的重要性,并主张将自体肋骨软骨作为可靠的替代方法。报告此类病例对于告知患者管理和研究CLR中有机硅植入物的长期安全性至关重要。
    Cleft lip rhinoplasty (CLR) corrects nasal deformities in cleft lip and palate patients. However, limitations exist in some countries like Japan regarding the use of silicone implants for CLR. While historical reports mention their use since the 1980s, long-term data is lacking. This case report describes a 53-year-old Japanese woman with bilateral cleft lip and palate who received a CLR with a silicone implant over 30 years ago. The implant calcified, causing nasal dorsum skin hardening and thinning, raising concerns of extrusion. To prevent potential extrusion, the implant was removed and replaced with autologous seventh rib cartilage grafts. Various grafting techniques were used for basal support, dorsal augmentation, and nasal tip refinement. The postoperative evaluation showed excellent results with no complications. This case highlights the importance of long-term follow-up after CLR with silicone implants and advocates for autologous rib cartilage as a reliable alternative. Reporting such cases is crucial for informing patient management and research on the long-term safety of silicone implants in CLR.

    乳头倒置是常见的,可能导致母乳喂养的挑战,性经历,和对自己外表的不满。目前,对最佳治疗方法缺乏共识。最近提出了在乳房切除术后乳房重建中使用光滑的硅胶植入物来重建乳头-乳晕复合体。这项研究提出了第一例使用这种方法治疗II级乳头内陷的患者,该患者先前未通过常规重建手术治疗。
    Inverted nipples are commonly observed and can lead to challenges in breastfeeding, sexual experiences, and dissatisfaction with one\'s physical appearance. Currently, there is a lack of consensus on the optimal treatment approach. The use of a smooth silicone implant to reconstruct the nipple-areola complex in post-mastectomy breast reconstruction has recently been proposed. This study presents the first case using this approach in a patient with a grade II inverted nipple who previously failed conventional reconstructive surgical treatment.

    目的:囊状挛缩是一种罕见但严重的有机硅植入隆鼻手术并发症。严重时,挛缩会影响鼻子的所有层面,造成严重的疤痕和毁容。目前尚无评估鼻子收缩的标准化方法,也缺乏关于严重挛缩症治疗的文献。因此,本研究旨在建立硅胶隆鼻术后继发鼻挛缩的综合分级体系和治疗方法。
    方法:我们对2012年至2021年出现鼻挛缩的患者进行了回顾性分析。所有术前照片均由两名整形外科医生进行评估,间隔一个月两次。拟议的评分系统包括:正常(一级),轻度挛缩伴可检测植入物(II级),中度挛缩伴皮肤变薄(III级),重度挛缩伴短鼻畸形(IV级),和背侧皮肤瘢痕的破坏性挛缩(Va级),或小柱缺乏症(Vb级)。使用kappa值来评估观察者之间和内部的一致性,以确定系统的可靠性。
    结果:根据87例患者,对于两个评估时间点,观察者之间的一致是实质性的(k=0.701和0.723).观察者内部的一致性对于评估者1(k=0.822)是极好的,对于评估者2(k=0.699)是实质性的。
    结论:使用此评分系统,我们提出了一种针对鼻子收缩的分级治疗算法。最值得注意的是我们在Vb级患者中使用radial前臂游离或前额皮瓣重建小柱。通过结合重建和美学原则,这种治疗方法为严重鼻子收缩的管理提供了有效和优雅的解决方案。
    方法:本期刊要求作者为每篇文章分配一定程度的证据。对于这些循证医学评级的完整描述,请参阅目录或在线作者说明www。springer.com/00266.
    OBJECTIVE: Capsular contracture is a rare but serious complication of silicone implant-based augmentation rhinoplasty. When severe, the contracture can affect all layers of the nose, causing significant scarring and disfigurement. There is currently no standardized method of evaluating contracted noses and a paucity of literature on the treatment of severe contracture. Therefore, this study aimed to establish a comprehensive grading system and treatment approach for patients with nasal contracture secondary to silicone implant-based rhinoplasty.
    METHODS: We conducted a retrospective analysis on patients who presented with nasal contracture from 2012 to 2021. All preoperative photographs were evaluated by two plastic surgeons, twice at 1-month intervals. The proposed grading system comprised: normal (grade I), mild contracture with detectable implant (grade II), moderate contracture with skin thinning (grade III), severe contracture with short nose deformity (grade IV), and destructive contracture with scarring of the dorsal skin (grade Va), or columella deficiency (grade Vb). Inter- and intraobserver agreement was assessed using the kappa value to determine the reliability of the system.
    RESULTS: Based on 87 patients, interobserver agreement was substantial for both evaluation time points (k = 0.701 and 0.723). Intraobserver agreement was excellent for evaluator 1 (k = 0.822) and substantial for evaluator 2 (k = 0.699).
    CONCLUSIONS: Using this grading system, we propose a graduated treatment algorithm for contracted noses. Most notable is our use of radial forearm free or forehead flaps to reconstruct the columella in grade Vb patients. By combining reconstructive and aesthetic principles, this treatment approach provides an effective and elegant solution for the management of the severely contracted nose.

    背景:囊状挛缩仍然是硅胶乳房植入术的常见并发症。病因,形成机制,诱发因素和偏好因素仍然是研究的主题。这项研究旨在证明与其他已知方法:抗生素和皮质类固醇相比,使用假体周围引入的自体脂肪预防包膜挛缩的有效性。
    方法:研究纳入了80只Wistar大鼠的队列,分为四个子组。所有受试者都接受了硅胶植入物,植入沿腹部中线形成的口袋中。第一个亚组作为对照组,在没有任何治疗的情况下放置植入物的受试者。对于第二和第三子组,植入物用抗生素溶液和肌肉注射地塞米松治疗,分别。最后一个亚组的受试者接受经假体周围引入的离心自体脂肪。
    结果:具有自体脂肪的亚组表现出明显较小的胶囊厚度,代表性不足,表面光滑。使用自体脂肪治疗硅胶假体与假体部位周围缺乏急性炎症有关。
    结论:自体脂肪有助于减少“非自我”反应,这导致形成由散布有脂肪细胞的成熟胶原纤维组成的假体周围囊。
    BACKGROUND: Capsular contracture remains a common complication in silicone breast implantation. The etiology, formation mechanisms, predisposing and favoring factors are still subjects of research. This study aims to demonstrate the effectiveness of using autologous fat introduced periprosthetically in preventing capsular contracture compared to other known methods: antibiotics and corticosteroids.
    METHODS: A cohort of 80 Wistar rats was included in the study, divided into four subgroups. All subjects received a silicone implant, implanted in a pocket created along the abdominal midline. The first subgroup served as the control group, with subjects having the implant placed without any treatment. For the second and third subgroups, the implants were treated with an antibiotic solution and intramuscular injections of dexamethasone, respectively. The subjects in the last subgroup received centrifuged autologous fat introduced periprosthetically.
    RESULTS: The subgroup with autologous fat exhibited a significantly smaller capsule thickness, which was poorly represented, with a smooth surface. The use of autologous fat for treating silicone prosthesis was linked with the lack of acute inflammation around the prosthetic site.
    CONCLUSIONS: Autologous fat helps to minimize the \"non-self\" reaction, which results in the development of a periprosthetic capsule consisting of mature collagen fibers interspersed with adipocytes.

    背景:在乳腺癌治疗后使用硅胶乳房植入物进行乳房重建的趋势一直在上升,以及在美学乳房程序。与硅酮植入物的存在相关的一系列非特异性症状被称为乳房植入物疾病(BII)。然而,BII没有严格的标准来具体定义这个术语。患者和医生对BII的兴趣与日俱增,敦促验证自己的“按需”解释病例。
    方法:在本文中,我们讨论了一个初步诊断为BII的病人,乳房重建后,并回顾了有关BII症状和病因的文献。美学修正的决定,不是外植体,是在对BII的诊断提出质疑时做出的,并诊断出由于对乳房重建的美学结果不满意而导致的躯体化。
    结果:通过更换植入物和对侧乳房固定术改善美观,使患者症状完全恢复。
    结论:根据我们的案例,我们指出,乳房再造后患者的BII诊断具有挑战性.我们建议在考虑这种诊断和进一步诉讼的同时,例如,外植体,尤其是乳房重建后的患者,应考虑一些排除标准.对手术结果的不满意也会导致躯体化和真实临床症状的存在,这不应与对有机硅颗粒的可能的自身免疫反应相混淆。

    BACKGROUND: There has been a rising trend in the use of silicone breast implants for breast reconstructions after breast cancer treatment, as well as in the aesthetic breast procedures. A cluster of non-specific symptoms related to the presence of silicone implant has been called breast implant illness (BII). However, there are no strict criteria of BII which would specifically define this term. The increasing interest in BII among patients and physicians urges verifying own cases of \"on-demand\" explantations.
    METHODS: In this paper, we discussed a case of a patient with initial BII diagnosis, after breast reconstruction, and reviewed the literature on the BII symptoms and aetiology. A decision for aesthetic revision, not explantation, was made as the diagnosis of BII was questioned, and somatisation due to dissatisfaction with the aesthetic result of breast reconstruction was diagnosed.
    RESULTS: Improving aesthetics by implant exchange and contralateral mastopexy caused a full recovery from patient\'s symptoms.
    CONCLUSIONS: Based on our case, we point on the fact that BII diagnosis in patients after breast reconstruction is challenging. We suggest that while considering such a diagnosis and further proceedings, e.g. explantation, especially in patients after breast reconstruction, some exclusion criteria should be considered. Dissatisfaction with the result of the surgery can also lead to somatisation and the presence of real clinical symptoms, which should not be confused with the possible autoimmune reaction to silicone particles.

    本文讨论了无症状和有症状的乳房植入物患者的适当初始成像。对于使用盐水植入物的无症状患者,不建议成像。如果存在破裂问题,超声通常是合适的,尽管盐水破裂通常是临床上明显的。FDA最近建议患者在初始硅胶植入手术后5至6年进行初始超声或MRI检查,然后每2至3年进行一次。在患有无法解释的腋窝腺病的患者中,使用当前或先前的硅胶乳房植入物,超声和/或乳房X线照相术通常是合适的,取决于年龄。在一个担心硅胶植入物破裂的患者中,超声或无造影MRI通常是合适的。在患有乳房植入物和可能与植入物相关的间变性大细胞淋巴瘤的患者中,超声通常适合作为初始成像。美国放射学会适当性标准是针对特定临床状况的循证指南,每年由多学科专家小组审查。指南的制定和修订过程支持对同行评审期刊的医学文献进行系统分析。既定的方法论原则,如建议评估分级,发展,评估或等级适用于评估证据。RAND/UCLA适当性方法用户手册提供了确定特定临床场景的成像和治疗程序适当性的方法。在那些缺乏同行评审文献或模棱两可的情况下,专家可能是制定建议的主要证据来源。
    This document discusses the appropriate initial imaging in both asymptomatic and symptomatic patients with breast implants. For asymptomatic patients with saline implants, no imaging is recommended. If concern for rupture exists, ultrasound is usually appropriate though saline rupture is often clinically evident. The FDA recently recommended patients have an initial ultrasound or MRI examination 5 to 6 years after initial silicone implant surgery and then every 2 to 3 years thereafter. In a patient with unexplained axillary adenopathy with current or prior silicone breast implants, ultrasound and/or mammography are usually appropriate, depending on age. In a patient with concern for silicone implant rupture, ultrasound or MRI without contrast is usually appropriate. In the setting of a patient with breast implants and possible implant-associated anaplastic large cell lymphoma, ultrasound is usually appropriate as the initial imaging. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

    背景:由于没有可用的术前评估乳房植入物大小的指南,因此在跨女性中进行隆胸手术是一项挑战。这是专门迎合他们的。我们研究的目的是得出术前乳房植入物大小估计的公式,这将消除个人偏见,帮助一对一的讨论,更好的理解,减少手术时间,成本,和翻修手术率。方法回顾性研究于2018年10月至2020年12月进行。我们维持了对患者进行测量的常规方案,此前已发表。线性多元回归方程被用来使用最小参数得出一个公式,即,CC(乳房下褶皱[IMF]处的胸围),POMP(乳房丘最大投影点的周长),和LOWERDIFF(拉伸乳头[IMF]和未拉伸乳头[IMF距离]之间的每个乳房的差值较低)。结果本期共有51名女性接受手术治疗。所用植入物的平均体积为354.51mL。并发症包括6名患者的疼痛和不适,两名患者延迟愈合,伤口开裂。利用这些数据获得了乳房植入物的术前计算公式。在遇到的并发症与插入的植入物超过计算尺寸的百分比之间发现了数学相关性。结论我们可以通过一个简单的公式来估计乳房植入物的大小,该公式仅需要四次人体测量。该等式对于外科医生来说是显著的优点,并且是用于患者教育的有用工具。如果在前瞻性研究中应用,它的有用性将得到确立。从我们的研究来看,似乎比计算尺寸高出9%是更好地避免的。
    Background  Breast augmentation in transwomen is a surgical challenge as there is no available guideline for preoperative assessment of breast implant size, which caters to them specifically. The aim of our study is to derive a formula for preoperative breast implant size estimation, which would remove the personal bias, help in one-to-one discussion, and better understanding, reducing operative time, cost, and revision surgery rate. Methods  This is a retrospective study conducted from October 2018 to December 2020. We maintained a routine protocol for measurements in our patients, which has been previously published. Linear multivariate regression equation was applied to derive a formula using minimum of parameters, namely, CC (chest circumference at the inframammary fold [IMF]), POMP (circumference at the point of maximum projection of breast mound), and LOWERDIFF (lower value of difference in each breast between the stretched nipple [IMF] and the nonstretched nipple [IMF distance]). Results  A total of 51 transwomen underwent surgery in this period. The mean volume of implant used was 354.51 mL. Complications consisted of pain and discomfort in six patients, delayed healing in two patients, and wound dehiscence in one. A formula for preoperative calculation of breast implant was obtained with these data. A mathematical correlation was found between complications encountered and the percentage by which the inserted implants exceeded the calculated size. Conclusion  We could estimate the breast implant size preoperatively through a simple formula that require only four anthropometric measurements. This equation is a significant advantage for the surgeon and a useful tool for patient education. Its usefulness will be established if applied in prospective studies. From our study, it appears 9% above the calculated size is better avoided.

    隆胸被认为是安全的,但乳腺植入物相关鳞状细胞癌(BIA-SCC)的罕见病例已有报道.本研究旨在系统回顾已发表的BIA-SCC病例,提供有价值的临床数据。审查包括14篇文章和18例BIA-SCC。观察到报告的BIA-SCC病例呈上升趋势,上世纪90年代有4例,2010年以来有14例。受影响患者的平均年龄为56岁,症状通常在隆胸后21年左右出现。用于整容手术的有机硅植入物最常与BIA-SCC相关。在所有情况下都需要去除植入物,有些病人需要做乳房切除手术.治疗方法多种多样,选择性使用化疗和/或放疗。估计6个月死亡率为11.1%,而12个月死亡率为23.8%。由于样本量有限,估计的6个月死亡率应谨慎解释。它似乎低于美国整形外科学会报告的比率,没有明确的原因,这种差异。这项研究强调了加强监测和信息共享对改善BIA-SCC检测和管理的重要性。医疗保健提供者在隆胸患者的长期随访期间应保持警惕。
    Breast augmentation is considered safe, but rare cases of breast implant-associated squamous cell carcinoma (BIA-SCC) have been reported. This study aimed to systematically review published cases of BIA-SCC, providing valuable clinical data. The review included 14 articles and 18 cases of BIA-SCC. An increasing trend in reported BIA-SCC cases was observed, with four cases in the 1990s and 14 cases since 2010. The mean age of affected patients was 56 years, and symptoms typically appeared around 21 years after breast augmentation. Silicone implants used in cosmetic procedures were most commonly associated with BIA-SCC. Implant removal was necessary in all cases, and some patients required a mastectomy. Treatment approaches varied, with the selective use of chemotherapy and/or radiotherapy. The estimated 6-month mortality rate was 11.1%, while the 12-month mortality rate was 23.8%. The estimated 6-month mortality rate should be cautiously interpreted due to the limited sample size. It appears lower than the rate reported by the American Society of Plastic Surgeons, without clear reasons for this discrepancy. This study highlights the importance of enhanced monitoring and information sharing to improve detection and management of BIA-SCC. Healthcare providers should maintain vigilance during the long-term follow-up of breast augmentation patients.
