RESUMO
BACKGROUND: In recent years, the PAP (profunda artery perforator) flap has gained popularity in reconstructive breast surgery. However, the tissue available for flap harvest is usually limited. Therefore, grafting two PAP flaps to form a stacked PAP flap for unilateral reconstruction of large breasts is a safe and reliable option. Patient We present the case of a 59-year-old patient arriving at our unit with prior bilateral nipple-sparing mastectomy and implant-based reconstruction after diagnosis of BRCA-2 mutation and breast cancer. Autologous reconstruction with a DIEP flap was the initial treatment suggested to our patient. Preoperative CT scans showed subpar perforators not suitable for anastomosis, ultimately resulting in unilateral DIEP flap reconstruction on the left side. After an uneventful postoperative period, the patient requested autologous conversion of the right side due to persistent symptomatic capsular contracture. To achieve symmetry with the contralateral breast, we decided to perform a stacked PAP flap for unilateral breast reconstruction. RESULTS: The combined flaps provided enough tissue to achieve a satisfactory aesthetic result and symmetry and weighed 600 g in total, while the single DIEP flap on the left side weighed 716 g. There were no complications during the surgical procedure. Postoperative recovery was uneventful, and the patient was discharged after seven days. There were no signs of adipose tissue necrosis at the most recent check-up. On the left donor side, there was a small wound healing defect, which healed well non-surgically. The patient was satisfied with the results. CONCLUSION: The PAP flap has become an established alternative to standard breast reconstruction procedures. The stacked PAP flap can provide a safe and efficient method for unilateral reconstruction of large breasts. Perfusion and drainage through the inferiorly anastomosed flap showed sufficient outflow and did not lead to increased adipose tissue necrosis. In our case, the total surgery time was not substantially longer than in single PAP flap surgery. Furthermore, the possibility of unilateral placement of two flaps may avoid follow-up operations such as multiple lipotransfers to equalise both breasts.

BACKGROUND: Efficient digitization in medicine still is in its infancy but undeniably has great potential for current and future challenges in health care. Thus far, the rollout of medical apps has not resulted in widespread use of smartphones in the German health care sector-the reasons for this have not been clarified so far. Nevertheless, the lack of user involvement in the development process and content creation might contribute to low acceptance of these products. OBJECTIVE: This study aims to outline an approach to involve medical expertise without any coding knowledge for developing medical app content and functions. METHODS: An end user-operable backend was built. Its usability was evaluated using a usability evaluation test protocol. The results of the usability tests were evaluated by the app development team, and the usability test was repeated for optimizing backend usability. In total, 40 criteria to measure the ease of app usage were defined a priori. The usability test comprised 20 tasks that had to be fulfilled. Usability tasks were analyzed for completion, dropout, and test duration. Due to the COVID-19 pandemic, digital videoconferencing platforms (Zoom and QuickTime Player) were used to complete usability questionnaires. Finally, several backend-based apps for several specialties (infectiology, plastic and reconstructive surgery, and orthopedics) were developed by health care professionals as prototypes. RESULTS: Initial usability testing was conducted with 5 participants (4 men and 1 woman; mean age 39.2, SD 5.97 years). All of them could complete the assigned backend tasks with only a few workflow interruptions and some minor errors. After usability optimization, the workflow completion time decreased from 5.03 minutes to 3.50 minutes, indicating a time saving. The basic backend structure was clear to all test users and the handling was intuitive to learn. Some minor errors in the backend occurred during the test rounds. The apps developed using the aforementioned approach are in clinical use as a proof of concept. CONCLUSIONS: Backends offering operability for medical professionals might have great potential for app development in the mobile health sector. Sophisticated and time-saving usability are pivotal for the acceptance of medical software, as illustrated by the backend-based apps presented herein, which are in clinical use as a proof of concept. Basic interventions are essential and sufficient for adequate usability optimization. Practicable, well-structured software usability evaluation is possible based on the usability evaluation test protocol.
RESUMO
(1) Background: Postoperative pain is a frequently underestimated complication significantly influencing surgical outcome and patient satisfaction. While abdominoplasty is one of the most commonly performed plastic surgery procedures, studies investigating postoperative pain are limited in current literature. (2) Methods: In this prospective study, 55 subjects who underwent horizontal abdominoplasty were included. Pain assessment was performed by using the standardized questionnaire of the Benchmark Quality Assurance in Postoperative Pain Management (QUIPS). Surgical, process and outcome parameters were then used for subgroup analysis. (3) Results: We found a significantly decreased minimal pain level in patients with high resection weight compared to the low resection weight group (p = 0.01 *). Additionally, Spearman correlation shows significant negative correlation between resection weight and the parameter "Minimal pain since surgery" (rs = -0.332; p = 0.013). Furthermore, average mood is impaired in the low weight resection group, indicating a statistical tendency (p = 0.06 and a Χ2 = 3.56). We found statistically significant higher maximum reported pain scores (rs = 0.271; p = 0.045) in elderly patients. Patients with shorter surgery showed a statistically significant (Χ2 = 4.61, p = 0.03) increased claim for painkillers. Moreover, "mood impairment after surgery" shows a dramatic trend to be enhanced in the group with shorter OP duration (Χ2 = 3.56, p = 0.06). (4) Conclusions: While QUIPS has proven to be a useful tool for the evaluation of postoperative pain therapy after abdominoplasty, only continuous re-evaluation of pain therapy is a prerequisite for constant improvement of postoperative pain management and may be the first approach to develop a procedure-specific pain guideline for abdominoplasty. Despite a high satisfaction score, we detected a subpopulation with inadequate pain management in elderly patients, patients with low resection weight and a short duration of surgery.
RESUMO
(1) Background: Postoperative flap loss and wound healing disorders are severe complications after microsurgical free flap surgery. Despite multiple clinical observations, a possible influence of season and external temperature on outcome are largely missing. (2) Methods: Retrospectively, data were collected from 151 patients receiving microsurgical free flaps from March 2018 to August 2019. Patients were divided into two cohorts. The winter group includes all patients who underwent surgery from October 2018 to March 2019 and the summer group al those who underwent surgery from April 2018 to September 2018. Data included demographic information, pre-existing conditions, flap characteristics, and postoperative complications like flap losses and wound healing problems. External temperatures during the first 14 postoperative days were documented and the predictor of flap loss and wound healing disorders was detected. (3) Results: In the winter group (October-March; Ø 7.24 °C) 72 patients (46 female, 24 males; Ø 57.0 years) and in the summer group (April-September; Ø 18.79 °C) 81 patients (48 female, 33 males; Ø 56.0 years) received free flap surgery. There were no significant differences in demography (age: p = 0.593; gender: p = 0.419; BMI: p = 0.141). We found a significant increase in flap loss during summer (χ2(1) = 6.626; p = 0.010; V = 0.209) strengthened by logistic regression analysis (p = 0.037; Exp(B) = 9.655). Additionally higher average temperatures 14 days postoperatively represents another main driver (p = 0.023, Exp(B) = 1.161) for postoperative flap loss. (4) Conclusions: The data confirm a significantly higher postoperative flap loss in the summer group. This information may potentially contribute to optimization of perioperative management and planning of elective and semi-elective surgeries.
RESUMO
Thirty-six patients were assessed after scapholunate ligament reconstruction using a portion of the extensor carpi radialis brevis through a dorsal approach. The median age was 53 years. Most (27/38) were graded as scapholunate advanced collapse Grade I. At a median of 47 months after treatment, hand function using the Disabilities of Arm, Shoulder and Hand Questionnaire was 12. The postoperative range of wrist flexion and extension movement was 77% and grip strength 92% compared with the uninjured side. The median patient satisfaction was rated as 9/10. Median pain scores without and with load, using the numeric pain scale (0-10), were 1 and 3, respectively. This reconstruction leads to initial normalization of radiological features, such as scapholunate interval, scapholunate and radiolunate angles, but a notable loss of the immediate postoperative reduction was observed in long-term follow-up, which was not accompanied by any deterioration in the clinical examination. This technique, even in scapholunate advanced collapse type I wrists, resulted in long-term, improved outcomes compared with other techniques.Level of evidence: IV.

Although capsular contracture represents one of the most important complications after breast augmentation, local inflammation and fibrosis can lead, in very rare cases, to capsular calcification, an often-forgotten radiological sign of capsular contracture. In this article, the authors present a clinical case of breast implant calcification in an 81-year-old patient. Although this complication has been rarely described, the literature was reviewed to clarify the role of the local microenvironment in capsular contracture and calcification. At present, capsular contracture patients are classified using the conventional Baker score and the histological Wilflingseder classification. As it was not possible to consider capsular calcification when classifying our patient using the traditional scores, the authors propose an updated version of the current scale.
RESUMO
Within the last 20 years, robotic-assisted surgeries have been implemented as routine procedures in many surgical fields, except in plastic surgery. Although several case series report promising results, technical and economic aspects have prevented its translation into clinical routine. This review is based on a PubMed and Google Scholar database search, including case reports, case series, clinical and preclinical trials, as well as patents. Past, recent approaches, ongoing patents, as well as eight specific systems for robotic-assisted microsurgery and their potential to be translated into a clinical routine, are described. They may lay the ground for a novel field within plastic surgery. This review provides an overview of the emerging technologies and clinical and preclinical studies and discusses the potential of robotic assistance in the field of plastic surgery.
RESUMO
BACKGROUND: Although postbariatric body contouring procedures have the ultimate goal of restoring quality of life, there currently exist minimal data assessing the effect of these procedures. OBJECTIVES: To identify the most important body contouring procedure for quality of life (QoL). SETTING: University Hospital, Online Questionnaire, Germany. METHODS: A cross-sectional study was designed using a validated version of the internet-based Body Q questionnaire, which was distributed among patients using social media and patient events. RESULTS: A total of 460 patients (443 female, 17 male) participated and fulfilled inclusion criteria. Of those patients, 191 (41.5%) had already undergone surgery, and the rest served as the control group. Patients in a postoperative status had a significantly (P < .05) higher QoL regarding all body regions. Additionally, patients who underwent body contouring surgery showed significantly higher QoL in regard to sexuality, society, body image, and psychosocial metrics. Abdominoplasty represents the most important procedure for QoL. The control group showed the greatest dissatisfaction in the area of the inner thighs. CONCLUSION: Body contouring procedures have been shown to significantly restore and enhance a patient's QoL. Conducting contouring surgeries is specifically associated with an increase in body image satisfaction as well as patient acceptance of certain body regions.

INTRODUCTION: While breast reconstruction has become more and more important within the past decade, research focus areas as well as trends are in constant change. METHOD: The publications from 2012 to 2021 were retrieved from the Web of Science Core Collection database. CiteSpace visualization analysis software was used to analyze the institutions, countries, regions, categories, and keywords on breast reconstruction research. RESULT: A total of 3092 articles were selected. The number of articles published in the last 10 years showed an upward trend year by year. The journal "Plastic and Reconstructive Surgery" had the largest number of publications and citations, representing the core journal. The USA had the largest number of publications and the most extensive cooperation with other countries. The research highlights mainly focused on the improvement of surgical techniques, enhancing postoperative recovery, and oncological safety. CONCLUSION: Over the past decade, research on breast reconstruction has developed steadily, and considerable achievements in the field of surgical techniques, postoperative recovery, and oncological safety were reached. Plastic surgeons should continue to strive for a higher level of evidence study designs, while also recognizing the importance of international and multiple-center cooperation.

INTRODUCTION: Robotic-assisted surgery (RAS) has evolved over the past decades. Currently, novel robotic systems for microsurgery are being launched onto the European market. This novel microscope (RoboticScope®, BHS, Innsbruck, Austria) is a high-definition camera system, connected to an augmented reality headset, projecting a clear image with high magnification in front of the surgeon's eyes. Motion tracking translates the surgeon's head movements onto the system via a multi-axis robotic arm. We report the first use of the robotic microscope for autologous breast reconstruction in humans. METHODS: In May 2020, ten autologous breast reconstructions were performed by our Team. Five reconstructions (three PAP flaps, one bilateral DIEP flap) were conducted with the robotic microscope and matched to five reconstructions using a conventional microscope. We compared ischaemia times, times for arterial and venous anastomosis, and complications. RESULTS: All procedures were performed successfully and safely. Overall time for anastomosis was 31 min (+/- 7 min) in the robotic group and 25 min (+/- 7 min, p = 0.30) in the control group. Flap ischaemia was 54 min (+/- 8 min) in the robotic group and 52 min (+/- 22 min, p = 0.87) in the control group. No intraoperative complications such as venous thrombosis or arterial embolism occurred. CONCLUSION: Robotic microscopes provide the technology to combine flexibility to choose different angles during pedicle preparation and improve the stationary procedure of vessel anastomosis. Novel robotic systems tailored towards refinement in microsurgery hold great potential for implementation in Plastic Surgery procedures.

INTRODUCTION: Although Covid-19 and especially lockdown periods have affected our everyday live, its impact on hand traumatology is under investigated. MATERIALS AND METHODS: We retrospectively analyzed all patients presenting at a FESSH accredited HTRC and level 1 trauma center in Germany during the Covid-19 lockdown period and an equivalent timeframe in 2019 regarding incidence of hand trauma, injury mechanism, type of injury and hand surgeries. RESULTS: 338 patients presented at our department with acute hand injuries. A significant reduction of work-related accidents was found during lockdown contrary to an increase of do-it-yourself related trauma. Although the incidence of hand trauma decreased during lockdown by 18%, the rate of hand surgery increased in absolute and relative numbers. CONCLUSIONS: Although Covid-19 has negatively impacting elective and semi-elective surgeries, acute hand surgery has gained in importance represented by a shift from work related to do-it-yourself trauma and an increased rate of surgical treatment. LEVEL OF EVIDENCE: IV (therapeutic).

BACKGROUND: Along with the higher availability of Internet, worldwide access and the use of cell phones, the demands of patients for digitalized medical care have increased. METHODS: A questionnaire-based prospective study of 405 patients was conducted to investigate their expectations and requirements of app-based "mHealth" applications. RESULTS: "Behavioral guidance after surgery," "overview of personal findings," and "contact with the treating physician" were the most important factors. In contrast, "exchange with other patients" seemed to be of less importance. CONCLUSION: There is a need for health-oriented apps among patients undergoing plastic and reconstructive surgery, especially with the requirements for individual postoperative care.

Postoperative loss of breast volume represents a significant parameter for outcome evaluation of breast reconstruction. Breast volume broadly varies- depending of reconstruction method as well as surgical differences. A structural pattern of breast volume loss provides an essential parameter for preoperative design, helps to reduce postoperative breast asymmetry rate and thereby the need for reoperation. Therefore we hereby compare volume change of the three main reconstruction techniques: autologous flap-based, prosthesis-based and autologous fat transplantation breast reconstruction.

Although breast surgeries for aesthetic or reconstructive purposes are regularly performed, no focus has been laid on establishing an adequate and reliable volumetry method. While CT and MRI scan represent methods that are already in clinical use, the 3D scan is a novel and promising tool, easy to use with the possibility to measure the anatomic breast volume in an upright position. Nevertheless, its reliability is broadly underinvestigated. LEVEL OF EVIDENCE V : This journal requires that authors assign a level of evidence to each article.

Because breast augmentation is one of the most popular cosmetic procedures, the issue of implant-related complications has been widely debated ever since the FDA approved the use of implants in 1962. Although decades have passed, breast implant illness (BII) still represents a poorly defined and controversial complication. With ongoing nonscientific discussion in the mainstream media and on social media, revealing the etiology of BII is urgent because knowledge of this subject ultimately influences patients' decisions. Little or no scientific research is currently available on BII and no final conclusions regarding its etiology, clinical manifestations, diagnostic criteria, or treatment have been made. This review aims to give an overview of the hypotheses on the etiology of BII and seeks inspiration to improve the conditions of BII patients.

The autologous lipotransfer represents an established method in the field of Plastic Surgery. As a reliable and safe method for breast reconstruction and breast augmentation it offers an alternative to established methods such as implants and flap surgery.Survival rate of adipose derived stromal cells limits success or failure of fat grafting. Slight changes in the fat grafting process can lead to huge changes in ADSC-survival rate.This review wants to optimize the fat-grafting process to ensure best outcomes.

INTRODUCTION: Adipose derived Stem Cells (ASCs) have been proven to play a key role in tissue regeneration. However, exposure to large amounts of cigarette smoke can drastically diminish their function. Erythropoetin (EPO), can modulate cellular response to injury. Therefore, we investigated the ability of EPO to restore the regenerative function and differentiation capacity of ASCs. MATERIAL AND METHODS: Human ASCs were isolated from abdominoplasty samples using standard isolation procedures. Cell identity was established by means of Fluorescence Activated Cell Scanning. Subsequently, isolated ASCs were cultivated with cigarette smoke extract both with and without EPO. Parameters investigated included cellular metabolic activity, adipogenic and osteogenic differentiation capacity, and in vitro wound closure capacity. For further enhancing wound closure, EPO was combined with Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) or Stromal Derived Factor-1 alpha (SDF-1 a). RESULTS: Cigarette smoke reduces adipogenic differentiation, the osteogenic differentiation capacity as well as the in vitro wound healing ability of human derived ASCs. EPO did not change metabolic activity of ASCs significantly. The addition of EPO could partially restore their function. The combination of EPO with GM-CSF or SDF-1 did not result in a synergistic effect regarding wound healing ability. CONCLUSION: Exposure to cigarette smoke significantly reduced the regenerative potential of ASCs. Treatment of ASCs exposed to cigarette smoke with EPO has the potential to partially restore their function.

INTRODUCTION: Diabetes mellitus remains a significant public health problem, consuming over $400 billion every year. While Diabetes itself can be controlled effectively, impaired wound healing still occurs frequently in diabetic patients. Adipose-derived mesenchymal stem cells (ASCs) provide an especially appealing source for diabetic wound cell therapy. With autologous approaches, the functionality of ASCs largely underlie patient-dependent factors. Diabetes is a significant diminishing factor of MSC functionality. Here, we explore a novel strategy to enhance diabetic ASC functionality through deferoxamine (DFO) preconditioning. MATERIAL AND METHODS: Human diabetic ASCs have been preconditioned with 150 µM and 300 µM DFO in vitro and analyzed for regenerative cytokine expression. Murine diabetic ASCs have been preconditioned with 150 µM DFO examined for their in vitro and in vivo vasculogenic capacity in Matrigel assays. Additionally, a diabetic murine wound healing model has been performed to assess the regenerative capacity of preconditioned cells. RESULTS: DFO preconditioning enhances the VEGF expression of human diabetic ASCs through hypoxia-inducible factor upregulation. The use of 150 µM of DFO was an optimal concentration to induce regenerative effects. The vasculogenic potential of preconditioned diabetic ASCs is significantly greater in vitro and in vivo. The enhanced regenerative functionality of DFO preconditioned ASCs was further confirmed in a model of diabetic murine wound healing. CONCLUSION: These results demonstrate that DFO significantly induced the upregulation of hypoxia-inducible factor-1 alpha and VEGF in diabetic ASCs and showed efficacy in the treatment of diabetes-associated deficits of wound healing. The favorable status of DFO as a small molecule drug approved since decades for multiple indications makes this approach highly translatable.

BACKGROUND: To elucidate the performance of carpometacarpal-I joint prostheses in comparison with the current gold standard treatment, resection-suspension arthroplasty (RA), we conducted a study comparing outcomes of the Ivory prosthesis to those of a cohort of patients receiving RA. METHODS: Initially, we had enrolled 34 prosthesis patients and 48 RA patients, of which 5 and 11 were lost to follow-up. We defined Eaton/Littler stage 3 osteoarthritis, no previous surgery, no concomitant arthrosis, no rheumatic arthritis, no history of trauma and a minimum follow-up period of 2 years as inclusion criteria. We assessed patient demographics, disability of the arm, shoulder, and hand score, pain via visual analogue scale, subjective strength of the thumb, range of motion (radial and palmar abduction and opposition), and patient satisfaction. All occurring complications were recorded. RESULTS: Follow-up included a mean period of 4.5 years (2-7.4) in the prosthesis cohort and 4.1 years (2-6.8) in the RA group. Disability of the arm, shoulder, and hand scores, pain scores, palmar abduction and opposition, and subjective satisfaction showed no significant differences between the two cohorts. Postoperative loss of strength was significantly less in the prosthesis group (p = 0.01). Moreover, we were able to demonstrate better range of motion in terms of radial abduction in the prosthesis group (p = 0.001). The overall complication rate was significantly higher in the prosthesis cohort (41.4% vs. 10.8%) (p = 0.008). Nevertheless, the Ivory prosthesis group showed a survival rate of 93.1%. CONCLUSION: As the high complication rate is compensated by a better functional outcome (enhanced range of motion and strength), we believe that prosthesis implantation can be a reasonable treatment option for carpometacarpal-I osteoarthritis in a particular patient group. Level of Evidence IIIl: Retrospective cohort study.

The use of mesenchymal stem cells for regenerative medicine is becoming more popular than ever before - even though their clinical usage is limited. Many ethical and translational questions, as well as legal aspects and uncertainty regarding safety inhibit the growth of appropriate therapies from promising scientific approaches.This paper demonstrates the main problems of the translation from stem cell based therapies from basic science towards their clinical use.
