Professor David Chwei-Chin Chuang is the first plastic surgeon who concentrated on peripheral nerve science that incorporated injuries, reconstruction, and researches in Taiwan. It took him 30 years to be recognized as a world expert in the field of peripheral nerve injury and reconstruction. He started his microsurgical career in 1984 and became an academic professor in 2000. His phenomenal career was inspired largely by mentors namely: Dr. Samuel Noordhoff who motivated him to become a plastic surgeon, Dr. Fu-Chan Wei who influenced him to become a micro-surgeon; Dr. Julia K Terzis (USA), Dr. H. Millesi (Austria), Dr. A. Narakas (Switzerland), and Dr. Toru Kondo (Japan) - all four of whom had primed him to become a peripheral nerve microsurgeon.
In the process of aiming to make a solid contribution in the world of microsurgery, Prof. Chuang has developed many concepts and techniques related to the following: peripheral nerve reconstruction that deals with the classification level of brachial plexus injury; classification of level of radial nerve injury; classification of severity of post-paralysis facial synkinesis and strategy for treatment; the classification of traction avulsion amputation of the major limb; the technique of gracilis myocutaneous flap harvest; the technique revolution of FFMT for facial nerve reconstruction; the surgical treatment of thoracic outlet syndrome; the subfascial anterior transfer for cubital tunnel syndrome; the operative methods of nerve transfer for irreparable brachial plexus avulsion injury; the contralateral C7 transfer with free vascularized ulnar nerve graft; the intercostals nerve transfer to the musculocutaneous nerve, and other nerve transfer procedures.
Despite his already quite hectic schedule, he still found the time to get involved in many types of researches, which are related to peripheral nerve and free functioning muscle transplantation. Also, his numerous experimental types of research have been published in Plastic and Reconstructive Surgery, one of which is the research for arterialized venous flaps using vaso vasorum changes that he completed in 2015.
Because of his unique field of medical expertise, Prof. Chuang has been invited in countless local and worldwide meetings for special lectures, symposiums and panels in Japan, Korea, China, Thailand, Singapore, Indonesia, India, Argentina, Italy, Finland, Kuwait, Hong Kong, Mexico, Turkey, Germany and the USA. Furthermore, he also co-authored a chapter in three versions of the textbook entitled “Plastic Surgery” (2nd version 2006, third version 2013, and a new coming fourth version). Aside from these seemingly untiring achievements, he did several presentations locally and internationally, which were profiled in quite a number of publications for different medical journals.
Prof. Chuang has been similarly sought as the International Associate Editor of Plastic and Reconstructive Surgery from 2014 to 2016, and his term has been extended from 2016 to 2018. In relation to the foregoing, Professor Chuang has twice hosted the "Instructional Course" for adult brachial plexus injury in 2009, and facial paralysis reconstruction in 2011. The third part (adult brachial plexus injury) of which, is coming soon this 2017.
To make his career in micro surgery more fulfilling, Prof. Chuang engaged himself with the Fellow Training Program of Chang Gung Memorial Hospital as one of the teachers, for hundreds of international foreign fellows. Along with this, he has treated international patients (approximately 100) from 20 different countries around the world.
As an authority figure in the field of micro-surgery, Prof. Chuang held vital positions as follows: Chief of Department of Plastic Surgery, Chang Gung Memorial Hospital, Taipei-Linkou; 13th President of Taiwan Plastic Surgical Association (2006-2008); 10th President of Taiwan Society for Surgery of the Hand (2009-2010); and First (1st) President of Taiwan Society for Reconstructive Microsurgery (2014-2016). At present, he is the 9th President of World Society for Reconstructive Microsurgery (WSRM) from March 2015 to June 2017. Prof. Chuang is undertaking every workable means and ways to fortify the relationship between the WSRM central office and the four regional societies (ASRM, ALAM, EFSM and APFSRM).
Prof. Chuang’s high hope is for the International Microsurgery Club and the International Microsurgery Journal to truly become the “World Society.”

Prof. Wang is the world-famous microsurgeon in China. He is currently the chief of Shandong Provincial Hospital Extremities Surgery Department, professor and chief physician of Chinese Association of Microsurgery, vice chairman of Chinese Medical Association Branch of Microsurgery and Branch of Hand Surgery, and committee member of Shandong Province Society for Surgery of the Hand, committee member of Chief Shandong Province Society for Trauma surgery, vice chief physician of Shandong Province Society for Reconstruction Surgery, and editorial board member of Chinese Journal of Clinical Anatomy.
Prof. Zeng-Tao Wang’s work is filled with creativity, mainly focusing on a combination of clinical research and basic medical research. He has published several world-class original results based on innovative techniques in the clinical medical field. For instance, Dr. Wang’s research made great improvements regarding low temperature organ preservation. He successfully replanted three cases of low temperature-preserved severed finger at -196°C. Moreover, he created assembled digit reconstruction, a procedure that brought to light a whole new vision to the traditional procedure which has been used for thirty years in the world by replanting digits through cutting off the index toe. This new technique allows reconstructed fingers to resemble original digits instead of toes. His creativity and innovative visionary leads the field of reconstructive surgery into a new era.
Even more, Prof. Wang exceeded expectations as he placed extra hard work in reviewing and revising microsurgery anatomy, which helped clarify several anatomy structures related to microsurgery. His contribution has an exceptional impact on the improvement of the field of reconstructive microsurgery. He also has many literary works regarding such matters, for instance, the “Clinical Anatomy Atlas of Microsurgery”.
To include Prof. Wang as the honorary editor-in-chief of International Microsurgery Journal is the breakthrough of the global microsurgery since we successfully overcome the barrier of language and platform, so people can learn the masterpieces from Chinese microsurgery masters. In the future we will have more cooperation not only in the journal, but also the conference, and the online platform. Hope the knowledge pooling and exchange can benefit the global microsurgeons and the patients.

This case report demonstrates an important supermicrosurgical technique for lymphedema, which was established by Isao Koshima in 1994. So far, over 2,000 cases of limb edema have been treated by this surgical method.
Immediate limb compression following the LVA procedure facilitates lymphatic drainage and increases the surgical efficacy by increasing the number of functioning anastomoses, and is a recommended postoperative practice.
Optimum operating conditions are an integral part of a successful microvascular surgery. We hereby introduce a new technique to make a low- cost microsuction cannula, which will be helpful for microvascular surgeons.
Improving efficiency of microvascular anastomosis by combination of open-loop and airborne suture techniques.
The authors describe various patient and breast-related factors that influence surgical outcomes while also addressing some techniques and principles for aesthetic microsurgical reconstruction.
Supraclavicular flap is an excellent fasciocutaneous flap for head and neck reconstruction due to its close color and texture match. In general, long flaps are required, but with the risk of distal necrosis. The aim of this study is to assess the relationship between the length and distal end necrosis of the supraclavicular flap.

A Fantastic platform for learning, professional development, and camaraderie. It's all just a few clicks away.
Division of the lateral plantar artery does not jeopardize the foot circulation because of anastomosis of the lateral plantar artery with the dorsalis pedis artery at the first intermetatarsal space. However, care should be taken with patients with peripheral artery occlusive disease and the flow of dorsalis pedis artery should be confirmed before surgery. Given the advantages of sizable vessel, easy dissection, and proximity to the defect, we believe that the lateral plantar artery might be a valuable option as recipient vessel for lateral plantar forefoot reconstruction.
Health care systems in many countries are confronted with increasing economic limitations. Thus, complex microsurgical procedures and extensive rehabilitation programs are poorly compensated. However, this case demonstrates a dramatic reduction of socioeconomic expenses by allowing a potential radiocarpal amputee to return to work for another estimated 30 years.
The 2nd instructional course for adult brachial plexus injuries is a fantastic opportunity to meet and learn from experts in the field. We cordially invite you to visit Chang Gung Memorial Hospital to participate in this unique learning experience.
Pedicled anterolateral thigh flap is a versatile option for reconstruction of complex soft tissue defects in varied anatomical regions. Its wide arc of rotation and less donor site morbidity are its added advantages.
The authors reviewed the MDCT images to show the number of lymph nodes superior to the saphenofemoral junction. In this study, on average, 3.67 nodes existed. However, there were 4 percent of cases with no countable nodes. This result indicates that appropriate preoperative screening is needed for this procedure.
The communication among international microsurgeons have switched from one direction (from paper, textbook) to multiway interactions through the internet. The authors believe the online platform will play an immensely important role in the learning and development in the field of microsurgery.
A 29-year-old male suffered from total loss of function of his left shoulder and upper limb after a traffic accident while riding a motorcycle. He was treated by a brachial plexus specialist at another hospital and managed surgically under the impression of total root avulsion.
The authors present a novel synthetic vascular model for microanastomosis training. This model is suitable for trainees with intermediate level of microsurgical skills, and useful as a bridging model between simple suturing exercise and in vivo rat vessel anastomosis during pre-clinical training.
Combining intraoperative ICG lymphography with NIR vein visualization can aid supermicrosurgeons in identifying lymphatic vessels and superficial venules to guide LVA incision placement. This guided approach significantly improves successful creation of LVAs when compared to the blind (anatomic) approach. In addition, the absence of linear ICG lymphographic patterns does not prevent formation of successful LVAs.
Authors present a case of combined proximal median and ulnar nerves extensive injury that was successfully managed using a novel safe strategy implemented.
Authors report a case of lower extremity lymphedema treated by LVA that preoperatively mapped not only lymphatic vessels by PDE, but also veins and venules using Veinsite™ .
Shoulder instability and lack of shoulder mobility are common and exhausting problems in adult patients with traumatic brachial plexus injury. Although primary nerve reconstruction remains the “gold standard” for brachial plexus management, secondary shoulder reconstruction by trapezius transfer is needed in neglected cases.
