The Preferred Reconstructive Choice for a Lower Third Tibial Exposure Defect: An Online Survey of 356 Microsurgeons.

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.

International Microsurgery Club: An Effective Online Collaboration System.

BACKGROUND: This study aimed to determine if International Microsurgery Club (IMC) is an effective online resource for microsurgeons worldwide, in providing an avenue for timely group discussions and advice regarding complicated cases, and an avenue for collaboration and information sharing. METHODS: All posts on the IMC Facebook group from member 1 to 8,000 were analyzed according to inclusion criteria and categorized into three categories-case discussion, question, and information sharing. Posts were retrospectively analyzed for number of responses, time of responses, number of "likes," number of treatment options, time of day, and demographics of authors and responders. RESULTS: A retrospective analysis of 531 cases showed an average response rate of 75.7% within 1 hour and as membership grew. The response rate stabilized averaging between 72.5 and 78% across all times of the day. An average of 11.8 microsurgeons was involved per case discussion, and 5.7 treatment options were provided per case. CONCLUSION: IMC is shown to be an effective resource to allow microsurgeons to access timely advice from other microsurgeons without time and distance limitation, and to have interactive group discussions on complicated cases.

The Preferred Management of a Single-Digit Distal Phalanx Amputation.

BACKGROUND: Replantation of a single digit at the distal phalanx level is not routinely performed since it is technically challenging with questionable cost-effectiveness. The purpose of this study was to analyze international microsurgeons' clinical decisions when faced with this common scenario. METHODS: A survey of a right-middle finger distal phalanx transverse complete amputation case was conducted via online and paper questionnaires. Microsurgeons around the world were invited to provide their treatment recommendations. In total, 383 microsurgeons replied, and their responses were stratified and analyzed by geographical areas, specialties, microsurgery fellowship training, and clinical experiences. RESULTS: Among 383 microsurgeons, 170 (44.3%) chose replantation as their preferred management option, 137 (35.8%) chose revision amputation, 62 (16.2%) chose local flap coverage, 8 (2.1%) chose composite graft, and 6 (1.6%) favored other choices as their reconstruction method for the case study. Microsurgeons from the Asia-Pacific, Middle East/South Asia, and Central/South America regions tend to perform replantation (70.7, 68.8, and 67.4%, respectively) whereas surgeons from North America and Europe showed a lower preference toward replantation (20.5 and 26.8%, respectively p < 0.001). Having completed a microsurgery fellowship increased the attempt rate of replantation by 15.3% (p = 0.004). Clinical experience and the surgeons' specialties did not show statistical significance in clinical decision making. CONCLUSION: From the present study, the geographic preferences and microsurgery fellowship experience influence the method of reconstruction for distal phalanx amputation. Multiple factors are taken into consideration in selecting the most suitable reconstructive method for each case scenario. In addition to the technical challenges of the proposed surgery, the cost of the procedure and the type of facility needed are important variables in the decision making process.

Impact of Social Media on Current Medical Conferences.

BACKGROUND: Medical conferences are forums for research, continuing medical education, and networking. Social media is increasingly used for communication and networking due to its low cost and ability to overcome large distances. This study investigates the impact that social media brings to the current conference system. METHODS: There are three parts of this study: (1) comparing two similar brachial plexus injuries (BPIs) courses without (2009) and with (2017) social media support, and the participants' feedback; (2) sharing our experiences in the management of the 2018 International Course on SuperMicrosurgery (ICSM) conference; and (3) evaluating the studies from the social media platform International Microsurgery Club (IMC), for the consensus pertaining to social media and conference system. RESULTS: With the help of social media, international attendance increased during the 2017 BPI conference compared with the 2009 BPI course (25 nationalities in 2009 vs. 35 in 2017). At least 23% obtained their meeting information through social media. Live surgery was the overall main attraction (79%). The 2018 ICSM meeting revealed that video posts increased attendance; videos that were the most effective in attracting (viewership) were either short or pertained to surgical procedures. Facebook, Messenger, and WeChat smartphone applications were effective for immediate communication and troubleshooting among the participants. From the IMC polls, 78% believe that the social media and the conference complemented each other. 97% attended the conference to update their skills and knowledge. CONCLUSION: Social media is a quick and economic tool in promoting medical conferences and instant messenger systems offer immediate communication amongst associates. Despite the popularity of social media, the conference still has its irreplaceable role. The combination of the conference and the social media enhances the training and education of microsurgeons.

Use of Social Media and an Online Survey to Discuss Complex Reconstructive Surgery: A Case of Upper Lip Reconstruction with 402 Responses from International Microsurgeons.

BACKGROUND: The best reconstructive strategy for upper lip defects is still in debate. The purpose of this study was to analyze the decisions made by international microsurgeons, who were participated through online questionnaire, distributed by email and social media network. MATERIALS AND METHODS: A case of a two-thirds upper lip oncologic defect was presented via an online questionnaire and 402 microsurgeons replied their treatment options. The data were then analyzed according to the geographic area, microsurgical fellowship, seniority, and subspecialty. All the data were analyzed using SPSS 22. RESULTS: A total of 27.7% of microsurgeons chose a free flap, while 72.3% chose a local/pedicle flap as their preferred method for reconstruction. The most common choice of free and local/pedicle flaps was radial forearm (73.6%) and Abbé (36.2%), respectively. The microsurgeons in Europe preferred local/pedicle flaps than free flap when compared with Middle/South America, Asia-Pacific, Africa and South Asia/Middle East (11.6% versus 50%, 43.4%, 29.3% and 27.3%, respectively, multivariant p < 0.05). The microsurgeons with microsurgical fellowships preferred to use free flaps (32.9% versus 17.5%, multivariant p = 0.021). There was no difference for the seniority and specialty of the microsurgeons. CONCLUSIONS: The online questionnaire is valuable and feasible for obtaining experts' opinions. This study provides a current global overview of surgical preferences for this common complicated clinical scenario.

Aesthetic Multiple-Toe Reconstruction With Combined Iliac Bone Graft and Wraparound Free Anterolateral Thigh Flap-A Case Report and Literature Review.

Compared with upper extremity injuries, toe amputations and their replantations are rare because of the difficulty of their relatively thinner soft tissue envelope. Consequently, fewer reconstructive options are available for toes and they are rarely reported in the literature. In this study, we reported a case of right third to fifth toe amputations and their subsequent reconstruction with iliac bone grafts and a free anterolateral thigh flap. After serial debulking and division procedures, 3 toes were divided successfully. Ten months after the initial operation, the patient regained pain-free functional ambulation despite some bone resorption noted on follow-up radiographs. The patient showed high satisfaction on her new toes in terms of aesthetical and functional outcomes. She was able to stand for over 30 minutes without pain. At the 2-year follow-up, the Foot Function Index was 18.3%. Although toe reconstruction is frequently considered unnecessary because of its relative high demand of surgical techniques and little gain on gait; nonetheless, in selected cases, toe reconstruction may still be beneficial if the metatarsophalangeal joints were intact and there is a strong individual desire for aesthetical restoration.

Three-dimensional comparative changes in the pharyngeal airway of patients with cleft after two-jaw orthognathic surgery.

BACKGROUND: The present study evaluated the three-dimensional changes of the pharyngeal airway after orthognathic surgery (OGS) in patients with unilateral and bilateral clefts, and in unilateral cleft patients with and without pharyngeal flap (PF). METHODS: Forty-five patients with unilateral or bilateral clefts receiving OGS were enrolled. Cone-beam computed tomography images were obtained before (T0) and after (T1) OGS. We measured the pharyngeal airway volumes, minimal cross-sectional area, and the horizontal displacement of facial landmarks. RESULTS: The patients with bilateral cleft exhibited smaller initial velopharyngeal volume (unilateral: 8623 mm 3; bilateral: 7781 mm 3; p = 0.211), while the velopharyngeal volume increased significantly with median of 744 mm 3 after OGS (p = 0.031). The median horizontal displacement of A point was 2.9 and 2.6 mm among the patients with unilateral and bilateral clefts, respectively (p = 0.276), and the median horizontal displacement of B point was -2.9 and -3.3 mm among patients with unilateral and bilateral clefts, respectively (p = 0.618). The unilateral cleft patients with PF exhibited lower initial velopharyngeal volume (PF+: 7582 mm 3; PF-: 8756 mm 3; p = 0.129) and a lower increase in velopharyngeal volume (PF+: 437 mm 3; PF-: 627 mm 3; p = 0.739) after OGS. CONCLUSIONS: Midface hypoplasia and the decrease in the velopharyngeal volume were more prominent among the bilateral cleft patients and the unilateral cleft patients with PF. After OGS, the velopharyngeal volume considerably increased among the bilateral cleft patients, but no considerable differences were noted among the unilateral cleft patients with PF.

Experiences and attitudes toward aesthetic procedures in East Asia: a cross-sectional survey of five geographical regions.

BACKGROUND: The demand for aesthetic procedures continues to grow globally, particularly in East Asian countries. The popularity of specific aesthetic procedures varies, however, depending on the particular East Asian geographical region being studied. This study aimed to evaluate the experiences of and attitudes toward aesthetic procedures in five East Asian countries/regions, including China, Japan, South Korea, Hong Kong, and Taiwan. METHODS: To recruit participants, an online questionnaire was designed and distributed on social media networks between May 2015 and March 2016. The statistical analysis was conducted using SPSS software, version 22.0. RESULTS: A total of 3,088 people responded (approximately 600 in each country/region). Of these, 940 participants (47.8%) responded that they had experienced at least one aesthetic procedure in the past. Taiwan had the highest number of participants who had experienced at least one procedure (264/940, 41%), with primarily non-surgical experiences. Only in South Korea did surgical cosmetic experiences exceed non-surgical cosmetic experiences (55.9% vs. 44.1%). The popularity of particular procedures and the motivation for undergoing aesthetic procedures varied by country. CONCLUSIONS: The popularity of aesthetic procedures continues to evolve. Similar trends were observed across the East Asian regions; however, each country had its unique demands and preferences. The information provided by this study can help aesthetic plastic surgeons further understand the patients in their corresponding region, customize their practice, and develop the requisite skills.

International Microsurgery Club is a closed, invitation-only group based on the Facebook social media platform. It was initiated on May 6, 2016, with the primary objectives of providing a convenient forum for discussing challenging cases, sharing valuable resources, and providing opportunities for research collaboration. The membership of International Microsurgery Club has grown to over 8700 at 2 years' existence, and continues to expand. International Microsurgery Club has become one of the largest online platforms for global microsurgeons. Here, the authors share their experience on how to establish a successful online platform for medical education.

Assessing the suitability of medial sural artery perforator flaps in tongue reconstruction - An outcome study.

INTRODUCTION: Oncological resection of the tongue can be reconstructed using a multitude of free flaps. The medial sural artery perforator (MSAP) flap has been well described in the literature in terms of its anatomy and harvest. However, functional outcome studies of post-reconstruction tongue defects using the MSAP flap have not been reported. This study represents the largest outcome study of patients with tongue reconstructions using MSAP flaps and a comprehensive review of its use. MATERIALS AND METHODS: From December of 2010 to October of 2015, 579 patients with subtotal glossectomy and free flap reconstructions in Chang Gung Memorial Hospital were retrospectively reviewed. 27 patients were reconstructed with MSAP flap. The pre- and intra-operative factors, as well as flap-related factors were analyzed. Post-operative complications and functional outcomes were evaluated. Donor site assessment were also conducted. RESULTS: A 96.3% flap survival rate was found with an average total operating time of 6 hours and 18 minutes. 84.6% of patients had primary closure of the donor site with and the remaining either had skin grafts or delayed closure. Donor site closure can be achieved primarily with no functional deficit. Speech intelligibility remained for most patients. 100% of patients resumed normal oral feeding. CONCLUSION: The MSAP flap is a small to medium sized flap most suited for subtotal glossectomy defects where optimal outcomes can be achieved in terms of speech clarity and restoration of oral intake.
