Long-term Complications of Gluteal Augmentation Using Aquafilling Filler: A Case Report.

The interest in gluteal augmentation using minimally invasive techniques has been increasing rapidly. Despite the fact that Aquafilling filler was described as biocompatible with human tissues, the number of associated complications has been rising. We present an exceptional case of a 35-year-old female patient, who suffered major long-term complications in association with Aquafilling filler injections in the gluteal region. The patient was referred to our center with signs of recurrent inflammation and severe pain focusing on the left lower extremity. A computed tomography (CT) scan showed multiple, communicating abscess formations all the way from the gluteal region to the lower leg. Therefore, an operative debridement was accomplished in the operating theater. Finally, this report emphasizes the severity of possible long-term complications when using Aquafilling filler especially in larger areas. Furthermore, the oncogenicity as well as toxicity of polyacrylamide, the core material of Aquafilling filler, remains uncertain, which is why further research is urgently required.

The perception of plastic surgery during the COVID-19 pandemic-an analysis of online search patterns on a medical information platform.

In 2020, the COVID-19 pandemic impacted global life and transitioned economies and societal perceptions of life as we knew it. Professional and social life mostly ground to a nadir during the first lockdown in Europe in March. As a consequence, measures aimed at preventing the spread of the virus were established in medical facilities also and elective plastic surgery procedures were temporarily suspended in our clinic and others. A majority of the population, including those potentially contemplating plastic surgery procedures, spent most of their time at home with ample time available to research information about surgical procedures and other topics online. This investigation analyzes the relevance of plastic surgery during the pandemic on the basis of online search behavior patterns. Online traffic data from the online platform http://www.mooci.org were extracted using Google Analytics over a period of 6 months. The parameters analyzed were: pageviews, session duration, and bounce rate. Additionally, differentiation by areas of interest has been obtained. The data were compared and analyzed before and after the beginning of the first hard lockdown in Austria, Germany, and Switzerland. There were no significant differences in regard to pageviews and session duration when comparing time points before and after the beginning of the hard lockdown. The bounce rate exhibited a significant decrease after the beginning of the lockdown, implying a more conscious search for information and greater absorption and retention. There was no difference that could conclusively be attributed to the pandemic in terms of specific areas of interest researched. Society's demand for information about plastic-surgical procedures continues to be steadily prevalent-despite, or even in particular, during a global pandemic. Providing reliable and readily available information about plastic surgery procedures is an important component of a functioning doctor-patient relationship and informed consent. This information may reflect society's increased interest in plastic surgery during the pandemic, or be simply reflective of more spare time at hand to allow for such research. Further studies should investigate the relevance of elective procedures over the entire course of the pandemic.

Quality and Vitality of Autologous Fat Grafts Harvested by Different Techniques: A Clinical Comparison Study.

BACKGROUND: Unpredictable outcomes with autologous fat grafting due to reabsorption processes present a major challenge for healthcare providers and patients. A higher number of viable adipocytes is considered to result in a higher volume being retained. Although various adverse factors have been extensively researched, other potential parameters have been less investigated or even neglected. OBJECTIVE: The aim of this study was to investigate the harvesting process of adipose tissue as the primary cause of cell damage and to determine the risk factors associated with low cell survival. METHODS: Thirty-nine male and female subjects undergoing planned elective liposuction or abdominoplasty were enrolled. Forty-seven lipoaspirates harvested by different liposuction techniques were analyzed. RNA isolation and real-time polymerase chain reaction was performed to elucidate differences in the expression of various adipocyte markers. Furthermore, scanning electron microscopy was performed on various samples to determine the cell damage caused by the different techniques. RESULTS: A statistically significant lower expression of peroxisome proliferator-activated receptor γ was detected in subjects with a higher BMI. A trend towards a lower expression of perilipin 1 in lipoaspirates harvested by a super wet + ultrasound technique, compared with dry and super wet techniques, was shown. The lowest level of cell damage determined from scanning electron microscopy images was in lipoaspirates harvested by the super wet + ultrasound technique, and this level was statistically significantly different from those obtained by the 2 other techniques. CONCLUSIONS: Optimization of the outcome in autologous fat grafting may be feasible by targeting and optimizing the harvesting process as a main risk factor for impaired adipocyte viability. Ultrasound-assisted liposuction might be considered a suitable harvesting technique.

Autologous Fat Grafting in Reconstructive Breast Surgery: Clinically Relevant Factors Affecting the Graft Take.

BACKGROUND: Autologous fat grafting is an effective tool for soft tissue augmentation in reconstructive breast surgery. Despite the major advantages of this minimally invasive approach, the unpredictability of graft survival presents challenges. OBJECTIVES: No clear consensus on the optimal technique has yet been published and well-defined prospective studies investigating impairing factors are lacking. This aim of this study was to generate valuable fundamental data. METHODS: Ten female patients undergoing elective autologous fat grafting after nipple-sparing mastectomy were enrolled. Punch biopsies and lipoaspirates were collected from the harvest site for histologic, gene expression, and scanning electron microscopic analysis. Noninvasive Lipometer measurements determining the subcutaneous adipose tissue thickness at the graft site were used to calculate the respective take rate. Patient- and surgery-related data were acquired and correlated with the take rate. RESULTS: A statistically relevant correlation between the take rate and the existing mean subcutaneous adipose tissue thickness at the grafted breast prior to surgery was observed. An approximate correlation was identified regarding the number of previous grafting sessions, body weight, and BMI. No statistically significant correlation was demonstrated for age, harvest site, or the mean adipocyte size. A lower level of cell damage was observed in scanning electron microscopic samples of washed lipoaspirates; and a strong indirect correlation with the expression of the adipocyte markers FABP4 and PLIN1 was apparent. CONCLUSIONS: Factors correlating to the take rate were identified. Future studies investigating the clinical relevance of each impairing factor are essential to contribute to the optimization of this valuable method.

Analysis of social media use by European plastic surgery societies: A missing link for #PlasticSurgery.

PURPOSE: The field of Plastic Surgery is prominent on social media around the world. Board certified plastic surgeons and societies of plastic surgery play a role in providing accurate, evidence-based information to the public, patients, and colleagues. The aim of this study was to explore the use of social media by European Plastic Surgery Societies. METHODS AND MATERIALS: A retrospective analysis of the presence and activity of European Plastic Surgery Societies on Facebook, Twitter and Instagram was conducted between December 12th 2018 and December 12th 2019. The results have been compared to the American Society of Plastic Surgeons. RESULTS: Twenty, eleven and nine European societies yielded an active account on Facebook, Twitter and Instagram respectively. Only seven European societies had an account on all three platforms and were therefore considered polypresent. The amount of followers of those seven societies was significantly higher than of the others (p-value = 0.02). Their activity yielded significantly more posts on Facebook (p-value = 0.02). The American Society of Plastic Surgeons had more followers on all three platforms than all European societies combined. CONCLUSION: Social media are still rather unexploited by European Plastic Surgery Societies. A tendency towards increased visibility can be observed, yet a higher penetration is required to further educate and engage through social media. The quantitative data provided serve as reasonable foundation for further studies and a guide for growth of #PlasticSurgery.

Three-Dimensional Evaluation of Static and Dynamic Effects of Botulinum Toxin A on Glabellar Frown Lines.

BACKGROUND: The use of injectable solutions for aesthetic purposes has increased tremendously, but lacks objective support. We aimed at assessing static and dynamic effects of botulinum toxin A (BoNTA) on glabellar lines by use of an objective three-dimensional methodology. METHODS: We prospectively collected three-dimensional stereographic photographs of two different facial expressions (pretreatment, 30 and 90 days posttreatment) in 21 patients, receiving a total of 20 units of BoNTA in both corrugator supercilii muscles. The primary endpoint was the three-dimensional static and dynamic surface irregularity, and secondary endpoints were the glabellar line scale and overall patient satisfaction. Blinded retrospective data analysis and statistical evaluation were performed with p < 0.05 considered statistically significant. RESULTS: Static glabellar lines (neutral facial expression) were significantly reduced by - 17% and - 24% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). Dynamic glabellar frown lines (firmest possible bilateral eye closure) demonstrated a reduction of surface irregularity by - 26% and - 21% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). The subjective dynamic glabellar line scale documented a statistically significant improvement on day 30 posttreatment (mean ± SD: 1.5 ± 0.8; p < 0.05) versus pretreatment (2.8 ± 1.0). Polled patients confirmed a subjective wrinkle improvement 90 days posttreatment. CONCLUSION: The presented setup detected even subtle changes of BoNTA treatment for facial wrinkling and is a promising asset for scientific evaluations of clinical studies analyzing the outcome and duration of efficacy of injectable solutions on the face.

Anatomy of the Vascularized Lateral Femoral Condyle Flap.

BACKGROUND: The perforators of the free lateral femoral condyle flap have yet to be adequately described in humans. Therefore, the authors investigated the perforator vessels of the lateral femoral condyle flap in an anatomical study and discussed potential clinical applications with a particular interest in its indication with vascularized bone and/or iliotibial band for tendon repair surgery. METHODS: The authors dissected thighs of 28 cadavers to evaluate the anatomical properties of perforator vessels that branch from the superior lateral genicular artery and supply bone, cartilage, subcutaneous tissue, and the iliotibial band of the lateral femoral condyle. RESULTS: In each dissected thigh, the superior lateral genicular artery was present and the average pedicle length was 38 ± 10 mm. The average diameter of the superior lateral genicular artery, proximal to its distribution into the deep articular and superficial patellar branches, was 2 ± 0.5 mm. A communication between deep articular and superficial patellar branches was seen in 96 percent of the dissected thighs. In 24 cases (86 percent), the authors were able to show the iliotibial band perforating vessel and harvest a free lateral femoral condyle flap as an osteochondral fasciocutaneous bone flap with vascularized tendon. CONCLUSIONS: Altogether, the authors' results indicate that the blood supply of the lateral femoral condyle flap is consistent and the lateral femoral condyle flap could serve as a free composite flap for complex indications in hand or limb reconstructive surgery. Clinical studies to compare the lateral femoral condyle to other well-established microsurgical free flaps are warranted.

Aesthetically and functionally satisfying reconstruction of an Achilles tendon and overlying skin defect in a 15 year old girl: a case report.

Achilles tendon and overlying soft tissue reconstruction presents an interdisciplinary challenge. In the literature many possible procedures are described, but each reconstruction in this region has its specific demands. Single stage reconstruction is normally pursued, but it is not always the best procedure for the patient, either aesthetically or functionally. We present a case of a 15 year old girl who suffered a soft tissue defect of 10cm×6cm in size at the area of the Achilles tendon due to a contact burn by an exhaust pipe during a motorcycle accident. For this case, reconstruction of the soft tissue defect using a free temporoparietal fascial flap (TPFF) and a full-thickness skin autograft was the best means to provide a satisfying result for both the patient and the surgeon.

The Austrian breast implant register: recent trends in implant-based breast surgery.

INTRODUCTION: Due to the fact that the number of breast implant surgeries for cosmetic and medical purposes is rising yearly, a discussion about the quality of service for both patients and physicians is more important than ever. To this end, we reviewed the Austrian Breast Implant Register with one specific question in mind: What are the trends? MATERIALS AND METHODS: In the statistical analysis of the Austrian Breast Implant Register, we were able to identify 13,112 registered breast implants between 2004 and 2012. The whole dataset was then divided into medical and cosmetic groups. We focused on device size, surface characteristics, filling material, device placement and incision site. All factors were considered for all examined years. RESULTS: In summary, the most used device had a textured surface (97 %) and silicone gel as the filling material (93 %). The mean size of implants for the cosmetic group was 240 cc, placement was submuscular (58 %) and the incision site was inframammary (67 %). In the medical group, the mean size was 250 cc. Yearly registrations had their peak in 2008 (1,898 registered devices); from this year on, registrations decreased annually. A slight trend away from subglandular placement in the cosmetic group was noted. Also, the usage of implants with polyurethane surface characteristics has increased since 2008. The smooth surface implants had a peak usage in 2006 and their usage decreased steadily from then on whereas the textured surface was steady over the years. DISCUSSION AND CONCLUSION: Keeping the problems related to the quality of breast implants in mind, we could recommend an obligatory national register. Organisations of surgeons and governments should develop and establish these registers. Furthermore, an all-encompassing international register should be established by the European Union and the American FDA (Food and Drug Administration); this might be useful in comparing the individual country registers and also would help in delivering "evidence based" medicine in cosmetic and medical procedures.

First experience using contrast-enhanced ultrasound to evaluate vascularisation of acellular dermal matrices after implant-based breast reconstruction.

UNLABELLED: Acellular dermal matrices (ADM) have been used frequently in therapeutic and prophylactic breast procedures. To date there have been no reports on vascularisation of ADMs and formation of tissue around them as seen with modern non-invasive imaging techniques such as contrast-enhanced ultrasound (CEUS). In this case series, we used CEUS to investigate the features of ADM in relation to vascular ingrowth and scaffold for "new" tissue formation. This is a retrospective evaluation of patients who underwent successful skin- and nipple-sparing mastectomy (SSM, NSM) with immediate IBBR using ADM from May 31, 2010, through December 28, 2012. Over a 24-month period, 16 patients, with an average age of 44 years (range 27-70 years), were evaluated with CEUS. No contrast agent allergies or side effects were reported for the ultrasound examination. After contrast agent injection (1-18 months postoperatively), homogeneous normal enhancement in the ADM and peripheral region with physiological tissue formation was seen in all patients. In this small study, the most obvious contribution of CEUS is the in vivo evaluation of vascular ingrowth and tissue formation after IBBR with ADM after follow-up of 1-18 months postoperatively. LEVEL OF EVIDENCE III: Retrospective cohort or comparative study; case-control study; or systematic review of these studies.

Analysis of functional outcome after posttraumatic thumb reconstruction in comparison to nonreconstructed amputated thumbs at the proximal phalanx of the thumb ray: a mid-term follow-up with special attention to the Manchester-modified M2 DASH questionnaire and effect size of Cohen's d.

BACKGROUND: Pollicization, toe to thumb transfer, and osteoplastic thumb reconstruction, along with free tissue transfer, are the most reported reconstructive procedures after traumatic amputation at the proximal and middle third of the thumb. We will present our clinical studies on functional outcomes with special attention to the M2 DASH questionnaire and effect size of Cohen's d. METHODS: Eleven patients (2 women and 9 men) with posttraumatic thumb reconstruction (three pollicizations of the index or index stump, four free lateral arm osteocutaneous neurosensory flaps, and four microvascular second toe to thumb transfers), performed during the period 2000 to 2007, were reexamined after 4.2 (SD ±2.1) years (range, 2-7 years postinjury). To ensure homogeneity among the patients' data, we selected only patients with isolated thumb amputations at the level of the proximal phalanx. RESULTS: The total M2-DASH score after thumb reconstruction was 18.55 (SD ±16.79). The M2-DASH score of patients with nonreconstructed thumbs was 32.77 (SD ±18.87). Pairwise comparisons between reconstructed and amputated thumbs showed statistically significant differences (Wilcoxon rank-sum test, p value = 0.03) and a highly effective improvement of hand function (Cohen's d = 1.10) after thumb reconstruction relative to amputated thumbs. CONCLUSION: Before selecting a candidate for thumb reconstruction, it is critical to decide on an individualized treatment plan. Factors such as the patient's occupation and the importance of the aesthetic appearance of the thumb must be carefully considered. The surgeon must investigate the patient's current use pattern and functional requirements before considering a reconstructive treatment.

Treatment of painful neuroma by resection and nerve stump transplantation into a vein.

Twenty-three patients (14 men, 9 women) with 24 painful neuromas underwent resection of neuroma and transposition of the nerve stump into an adjacent vein. The neuromas resulted from amputations (N = 7), tumor excision (N = 5), laceration injuries (N = 4), different types of wrist surgery (N = 3), vein-stripping procedures (N = 2), open fracture of the radius (N = 1), and toe harvest for thumb reconstruction (N = 1). The duration of painful symptoms averaged 66.7 weeks at the time of operation. Average follow-up was 26.5 months. In 22 patients the symptoms improved permanently. Twelve patients experienced complete and permanent relief of pain; some mild degree of pain returned in 8 patients. Two patients experienced moderate pain, and pain recurred unchanged 2 months postoperatively in 1 patient. The results presented are consistent with results of animal experiments demonstrating that typical neuroma does not develop in nerve stumps transposed into veins. Further clinical use of this approach is encouraged.

Treatment of spider leg veins with the KTP (532 nm) laser--a prospective study.

BACKGROUND AND OBJECTIVES: Spider leg veins are telangiectasias located intracutaneously. This condition poses a cosmetic problem. STUDY DESIGN/PATIENTS AND METHODS: The purpose of this study was to determine what influence the KTP (532 nm) laser has on spider leg veins dependent on the vascular diameter and to what extent the skin has been affected. Seventy female patients were treated in three laser sessions. Analysis was done 30 weeks after the last laser treatment session. RESULTS: Fifty-six patients completed the study. In group 1 (vascular diameter < or = 0.6 mm), spider leg veins were no longer visible in 33%; in 40%, a decrease in vascular diameter could be observed; in 27%, no change in size occurred. In group 2 (vascular diameter 0.7-1.0 mm), laser-treated spider leg veins were visible in all patients. Hyperpigmentation occurred in 13 patients. CONCLUSIONS: The KTP (532 nm) laser is an effective for treating spider leg veins having a vascular diameter under 0.7 mm.
