Background One of the most challenging yet common areas in reconstructive surgery is the closure of defects in the lower leg. Surgeons can choose from several reconstructive options including local and free flaps. The aim of this study was to understand the reconstructive strategy for lower leg defects of different microsurgeons around the world by harnessing the power of social media and online questionnaires. Methods A case of a patient with an exposed plate over distal tibial fracture was presented via an online questionnaire distributed on various social media platforms. A total of 369 international microsurgeons replied with their preferred treatment choice. The data were analyzed according to geographic area, microsurgical training, seniority, and subspecialty. Results Among all the respondents (n = 369), 64% would have opted for a free flap reconstruction, while the remaining 36% would have opted for a local/pedicle flap. In the group that would have opted for a free flap, 63% would reconstruct the defect using a free fasciocutaneous flap, while the remaining 37% would have used a free muscle flap. In the local flap group, 60% would have used a local perforator while 30% would have chosen a conventional local flap. While North American and European microsurgeons had a clear preference toward free flaps, Asian, Middle Eastern, African, and South American surgeons were evenly divided between local and free flaps. Conclusion In this study, we provide a current global overview of the reconstructive strategies for a lower limb with skin defect and bone or prosthesis exposure. We hope that this will be able to help global microsurgeons and patients worldwide. [ABSTRACT FROM AUTHOR]

Background  The impact of the coronavirus disease 2019 (COVID-19) outbreak shut down most conferences. To minimalize the influence, virtual meetings sprang up subsequently. International Microsurgery Club (IMC), as one of the largest professionals-only online microsurgery education groups worldwide, began to host regular weekend webinars during the pandemic to fill the knowledge gap. This study aims to discuss how webinars have fundamentally changed the way knowledge is delivered and exchanged. Methods  From February 29, 2020 to March 14, 2021, 103 IMC webinars were reviewed and analyzed in detail to determine the use, benefit, and effect. A comparison between webinars hosted by the different societies was made as well. A questionnaire survey focusing on attendees' behavior, attitude, and using habit about webinars was also made. Results  As for the 103 IMC webinar events, the peak participants were 112.3 people in average. The members requesting to join IMC abruptly increased during the pandemic, and the group activity increased dramatically. From the questionnaire (n  = 68), the satisfaction level was high (8.88 ± 1.18/10). The respondents were most satisfied with the good quality of the speakers (73.5%). Not only hosts our webinar series but IMC also serves as the platform that welcomes webinars from other societies to share their information. In September 2020, International Microsurgery Webinar League was established via the significant webinar hosts, with more than 300 recorded webinar talks connected successfully. Conclusion  As the knowledge revolution driven by COVID-19 will continue, IMC will keep playing an essential role in exploring new and emerging opportunities to improve knowledge dissemination worldwide beyond the space-time boundary.

Background  Gynecological reconstruction is difficult, particularly in cases with recurrence and received previous surgeries and/or radiotherapy and necessitate secondary reconstruction. Perforator flaps can preserve other donor sites for potential later reconstruction, and they also can be better tailored to the defect. We hypothesized that the use of perforator-based flaps can better restore the defect with less complications. Methods  A retrospective review was conducted of all patients who underwent vulvar–perineum reconstruction between 2011 and 2018 by the senior author, and oncologic and reconstructive outcomes and complications were analyzed. Results  Thirty-three patients underwent 55 soft tissue reconstructions for vulvar–perineum defects during the study period. The mean follow-up time was 27.6 ± 28.9 months. Squamous cell carcinoma was the most common cancer (45.5%). For 11 patients (33.3%), the procedures were performed for the treatment of recurrent cancer. The average defect size was 39.8 ± 34.3 cm 2. The overall survival rate was 90.3%. Profunda artery perforator flaps were the most commonly applied flap for reconstruction in both the primary and recurrent groups. Poor wound healing was the most common complication which occurred in 10 of the 55 flaps (18.2%). Perforator flaps presented fewer complications than myocutaneous flaps or traditional random flaps. Similarly, Island pedicle flap design also presented fewer complications than traditional rotation flaps. With proper reconstruction, previous surgery or radiotherapy did not contribute to an increase in complications. Conclusion  In our experience, perforator flaps can provide satisfactory reconstruction for perineum reconstruction with low postoperative complications while preserving other donor sites in the event of disease recurrence for repeat resection and reconstruction. Previous surgery or radiotherapy did not increase the complications or preclude its usage. A redefined reconstructive ladder was created to help selecting the best state-of-the-art technique for reconstruction to achieve better results. [ABSTRACT FROM AUTHOR]
