Dr. Tommy Nai-Jen Chang is a board-certified plastic surgeon in Taiwan. Currently, he is an Associate Professor in the Division of Reconstructive Microsurgery, Department of Plastic and Reconstructive Microsurgery, Chang-Gung Memorial Hospital, Linkou Medical Center, Taiwan. Dr. Chang finished his residency at Chang-Gung Memorial Hospital in 2011 and was appointed as staff of the department. He learned peripheral nerve reconstruction from Prof. David Chwei-Chin Chuang since 2012. Between 2015 and 2016, Dr. Chang completed a peripheral nerve research fellowship at the Hospital for Sick Children (SickKids) in Toronto, Canada, supervised by Dr. Gregory Borschel, Dr. Tessa Gordon and Dr. Ronald Zuker. After several years of peripheral nerve training under the guidance of Dr. David Chuang and Dr. Gregory Borschel, Dr. Chang is now capable of performing all types of peripheral nerve surgery. Currently, Dr. Chang works with Professor David Chwei-Chin Chuang and Dr. Johnny Chuieng-Yi Lu for peripheral nerve reconstruction for adult and pediatric brachial plexus injury, facial paralysis, and reconstruction of upper and lower extremity defects, decompression neuropathy including carpal tunnel, cubital tunnel, thoracic outlet syndrome, and the neurogenic tumors.
In addition to exploring motor nerves, Dr. Chang has also explored the sensory and autonomic nervous system as well in recent years and advanced some new areas, such as breast and nipple neurotization, robotic-assisted sympathetic trunk reconstruction, and hyper-selective neurectomy to treat primary hyperhidrosis. Besides, Dr. Chang also does microvascular surgery for Head and Neck reconstruction, perineal reconstruction, and extremities reconstruction. A total of 80 articles have been published in literature until the year 2022, mainly in the field of reconstructive microsurgery.
His research interests include peripheral nerve regeneration and reconstruction, and social media for microsurgery education. Dr. Chang founded the International Microsurgery Club (IMC) in 2016; until now, this group represents the largest online microsurgery platform. Dr. Chang was invited as the editor-in-chief of International Microsurgery Journal (IMJ) in 2017 and established International Microsurgery Website (IMW) in 2018 to provide educational resources for microsurgery surgeons worldwide. Dr. Chang coordinates the IMC Webinar Series during the COVID-19 pandemic to provide continuous education to global microsurgeons in 2020. By April 2022, there had been over 210 events, and all of the recordings were available on the IMW for members to access for free.
Aside from IMC, in Sep 2020, Dr. Chang also coordinated the main microsurgery webinar hosts and created an International Microsurgery Webinar League. Over 500 free accessed microsurgery-related free webinar talks were then connected online automatically, and the power of online learning of this system continues to expand and benefit the global microsurgeons.
Prof. David Chwei-Chin Chuang is the first plastic surgeon who concentrated on peripheral nerve science that incorporated injuries, reconstruction, and research 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, Prof. 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. 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 of 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.
Moreover, Prof. Wang excelled above and beyond expectations by taking the time to review and revise microsurgery anatomy, which clarified certain anatomy structures associated with microsurgery. As a result of his contributions, reconstructive microsurgery has been significantly improved. Furthermore, he has written many literary works pertaining to such topics, such as the "Clinical Anatomy Atlas of Microsurgery".
It is indeed a significant step forward in the development of global microsurgery to have Prof. Wang serve as the honorary Editor-in-Chief of the International Microsurgery Journal since with this collaboration, we have succeeded in removing the barriers of language and platform, so people are able to learn the techniques from Chinese microsurgeons. There will be more cooperation not only in the journal, but also in the conference and the online platform in the future. This knowledge exchange and pooling should be beneficial to global microsurgeons and patients alike.

The authors describe a case of ischemia of the lower extremity following a free fibula harvest for head and neck reconstruction. The authors discuss preoperative, intraoperative, and postoperative strategies to assist in diagnosing and managing risks associated with free fibula flap harvesting in this paper.
In a cost-effective and portable way, a novel method was developed to assist trainees in spinal surgery to gain and develop microsurgery skills, which will increase self-confidence. Residents at a spine surgery center were assessed before and after training on the effectiveness of a simulation training model. The participants who used the training model completed the exercise in less than 22 minutes, but none could do it in less than 30 minutes previously. The research team created a comprehensive model to train junior surgeons advanced spine microsurgery skills. The article contains valuable information for readers.
The loupe plays a critical role in the microsurgeon's arsenal, helping to provide intricate details. In the absence of adequate subcutaneous fat, the prismatic lens of the spectacle model may exert enormous pressure on the delicate skin of the nasal bone. By developing a soft nasal support, the author has incorporated the principle of offloading into an elegant, simple yet brilliant innovation. A simple procedure such as this could prove invaluable for microsurgeons who suffer from nasal discoloration or pain as a result of prolonged use of prismatic loupes. With this technique, 42% of the pressure applied to the nose is reduced.
Smartphones and cellular technology have revolutionized flap monitoring. Smartphones provide low-cost thermal imaging alternatives to flap monitoring. It remains unclear, however, whether this method is accurate or reliable. It may be challenging to use smartphone thermal imaging when clinicians fail to communicate clinically relevant events. The authors demonstrate three instances in which the thermal imaging information on smartphones was misleading. Each case is analyzed to determine how clinical decisions should be made.
The article describes the case of a 27-year-old man who suffered from scarring at the penopubic junction as a result of penis lengthening surgery.

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.

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.
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.
The authors present a revised application of the composite iliac crest bone free flap for hemimaxillectomy defects. This flap solely can give a support to the eye globe and the dental implants without osteotomies and titanium meshes. The upper ridge of the flap can be shaped to replicate the curvature of the orbital floor. The inner oblique muscle and the deep fascia can serve as an additional material for separation of the oral cavity from the nasal airway. Utilization of the Customized Contour Implants gives a surgeon a refining instrument for aesthetic correction of facial projection.
The authors proposed a new less invasive island flap, namely the first metatarsal artery capillary perforator flap. The advantages of this flap include the preservation of the first metatarsal artery and the adiposal tissue in the web space, thereby preventing compression around the remaining deep peroneal nerve.
The authors present a retrospective review of 7 patients who underwent wide excision of the malignant tumors around the clavicle. Patient demographics, clinical details, the arc of rotation, outcome, and complications were analyzed.
Patients with gynecological abdominal wall malignancies can benefit significantly from radical resection and autologous reconstruction. The pedicled anterolateral thigh flap is the preferred donor site, offering a reliable solution to abdominal wall reconstruction in this setting. The satisfactory results should prompt a more aggressive surgical approach for these patients. This article describes the authors' experiences with the abdominal reconstruction following surgical resection of gynecological abdominal wall malignancy using pedicled anterolateral thigh flap.

This study describes the authors’ experience regarding a successful free tissue transfer in a vessel-compromised neck. The authors also propose an algorithm for management of vessel-compromised neck.
The authors demonstrated the utility of hemi-intravascular stenting technique in a pediatric thumb replant.
Facial palsy affects both the functional and aesthetic aspects of the face. Many techniques for both static and dynamic facial reanimation have been described. Authors present their series of facial reanimation using the functioning free gracilis muscle flap innervated by the masseteric nerve.
This study reviews the reconstruction modalities within the multidisciplinary approach for chest wall reconstruction. The authors have proposed an algorithm that is formulated based on their experience to manage chest wall defects following cancer resection.
LVA and vascularized lymph node transfer VLNT are established lymphedema treatments. However, LVA is only effective for early disease and VLNT can cause donor-site lymphedema and contour deformity. VLVT is free of these limitations. The authors described their experience of a new VLVT technique.
The ALT and AMT flaps are the most commonly used thigh free flaps for intraoral reconstruction. Recently, PAP flap has been proposed as an alternative. This study aimed to compare the thickness of these thigh flaps and to identify the factors influencing flap thickness in our population.
Authors discuss a silicone tube that provides structural support to vessels throughout the entire precarious suturing process. This modification of the conventional microvascular anastomosis technique may facilitate initial skill acquisition using the rat model.
Authors proposed a simple innovative technique that helps in achieving a clear surgical field at the time of venous repair by diverting the venous bleeding through a glove finger and at the same time preventing venous congestion of the flap.
PEDs can be used as alternative means of magnification in microsurgery training considering that they are superior to surgical loupes in magnification, FOV and WD ranges, allowing greater operational versatility in microsurgical maneuvers, its behavior being closer to that of surgical microscopes in some optical characteristics. These devices have a lower cost than microscopes and some brands of surgical loupes, greater accessibility in the market and innovation plasticity through technological and physical applications and accessories with respect to classical magnification devices. Although PEDs own advanced technological features such as high-quality cameras and electronic loupes applications to improve the visualizations, it is important to continue the development of better technological applications and accessories for microsurgical practice, and additionally, it is important to produce evidence of its application at surgery room.
Avulsion injuries and replantation of the upper arm are particularly challenging in the field of traumatic microsurgery. At present, the functional recovery of the avulsion injuries upper arm after the replantation is generally not ideal enough, and there is no guideline for the surgeries. The aim of this study was to analyze the causes of failure of the upper arm replantation for avulsion injuries, summarize the upper arm replantation’s indications, and improve the replantation methods.
VSG is a type of bariatric surgery that is accepted as the simplest but most efficient surgical modality to treat morbid obesity. A mouse model of VSG has been widely utilized to investigate the underlying mechanisms of VSG. There are numerous microsurgical techniques for VSG in mice, and we report herein a modified technique with 2 disposable micro-clamps to simplify the surgery.
This article presented 3 cases diagnosed with chronic fatigue syndrome, severe skin adjuvant infiltration and skin ulcers.
This case report describes authors successfully attempt to perform a topographically correct sural nerve transplantation in the extracranial facial nerve stem using the intraneural facial nerve stem topography proposed by Meissl in 1979. This is the first reported case of successful fascicular nerve grafting of the facial nerve stem following extensive laceration.
ICG lymphography is an invaluable tool in lymphedema management. Both immediate and delayed scans are needed when performing the study. The delayed scan needs to be performed at the time of the lymphographic plateau to appreciate the full extent of the pathology. Using a recumbent cross trainer, the lymphographic plateau can be achieved in 15 minutes following ICG injection. We have found this exercise enhanced ICG lymphography protocol worthwhile of adoption by high volume lymphedema centers to raise diagnostic accuracy and efficiency.
The implications of rebound heparin hypercoagulability following cessation of therapy in microsurgery is unreported. In this article the authors report two cases of late digit circulatory compromise shortly after withdrawal of heparin therapy. The authors also propose potential consideration for changes in perioperative anticoagulation practice to reduce this risk.
The supraclavicular flap has gained popularity in recent years as a reliable and easily harvested flap with occasional anatomical variations in the course of the pedicle. The study shows how the determination of the dominant pedicle may be aided with indocyanine green angiography. Additionally, the authors demonstrate how they convert a supraclavicular flap to a free flap if the dominant pedicle is unfavorable to a pedicled flap design.
A thin profunda artery perforator flap harvested from the left thigh is shown in this video. Preoperative computed tomographic angiography is used to assess morphology of the perforators and its branches, pedicle length and vertical location of the two branches from the ischial tuberosity. These measurements are translated on to the patient. Locations of both branches are confirmed with a handheld doppler. The authors concluded that preoperative computed tomographic angiography is a useful technique to provide detailed anatomic information on morphology of perforators, course through the septum or muscle above the deep fascia and skin thickness. Computed tomographic angiography allows quick and easy assessment of the whole vascular anatomy of the leg and helps to arrive at the decision about selection of the best flaps based on the characteristics of the defect and on the individual anatomy of the patient.
The senior author (Dr. Isao Koshima) designed a tibial osseo-periosteal (TOP) flap. TOP flap has a favorable anatomical position with a thin skin around it, hence it is a good option for an island flap. TOP flap can be used for various mild to moderately sized osteo-cutaneous defects with low morbidity. In this article, the authors describe their experience of the first reported cohort of TOP flaps in clinical practice.
The video presents a useful technique for microvascular anastomosis in reconstructive surgery of the head and neck. It is advantageous to use this series of sutures when working with limited space, weak vessels (vessels irradiated, or with atheroclastic plaques), suturing in tension, or suturing smaller vessels (less than 0.8 cm in diameter).
Osteoarthritic finger joints are often repaired with joint implants, arthrodesis, or a vascularized interphalangeal joint graft. However, grafts can damage the donor toe. Based on the results of this study, the authors suggest that vascularized distal interphalangeal joint transfers from the second toe may be suitable for reconstructing these defects through microsurgery.
