Total scalp avulsion is rare but a devastating injury. This condition burdens the patient with disfigured cosmetic appearance and permanent psychosocial trauma. Throughout history, this condition has been favored in women working with mechanics since the long hair function as a vector appliance for oblique pull of the hair into a stationary torque. We present our experience of the replantation of the total avulsed scalp in male, first to be reported in Korea. Warm ischemic time was exceeding 16 hours along with severe crushed condition of the detached margin, a relatively satisfactory result was obtained.

Purpose: The purposes of this study were to explore changes in pain, mood and the level of posttrauma risk for 2 weeks after acute hand microsurgery and determine predictors of pain 2-week after microsurgery. Method: Using a sample of 84 patients with hand microsurgery, pain, mood, and posttrauma risk were measured by the Brief Pain Inventory-Korea, the modified Profile of mood states, and the Posttrauma risk checklist at 1-day, 1-week and 2-week post-microsurgery. Repeated measures ANOVA and Multiple regression analysis were conducted to evaluate changes in pain, mood, and posttrauma risk over time after the surgery and determine predictors of pain 2-week after the surgery. Results: Pain significantly decreased (F=63.22, p<.001), mood significantly improved (F=41.04, p<.001) 2 weeks after microsurgery and interestingly, posttrauma risk significantly decreased from baseline to 1-week microsurgery but increased at 2-week after microsurgery (F=24.66, p<.001). Approximately 57% of the variance of pain 2-week post-microsurgery was explained by pain at 1-week post-microsurgery, mood and the numbers of injured fingers. Conclusion: The findings suggest the pain control for 1week after acute surgery being critical and posttrauma rehabilitation of injured finger being necessary. Developing nursing interventions is urgently needed to help individuals with impending hand microsurgery.

Microsurgery is a precise surgical skill that requires an extensive training period and the supervision of expert instructors. The classical training schemes in microsurgery have started with multiday experimental courses on the rat model. These courses have offered a low threat supervised high fidelity laboratory setting in which students can steadily and rapidly progress. This simulated environment allows students to make and recognise mistakes in microsurgery techniques and thus shifts any related risks of the early training period from the operating room to the lab. To achieve a high level of skill acquisition before beginning clinical practice, students are trained on a comprehensive set of exercises the rat model can uniquely provide, with progressive complexity as competency improves. This paper presents the utility of the classical rat model in three of the earliest microsurgery training centres and the new prospects that this versatile and expansive training model offers.

Since surgery is usually a difficult task because of physiological tremor, eye strain, and tremor, contagious and radioactive hazard, it is necessary to develop micro-surgery telerobotic system using improved tools suitable for their specific tasks. Nowadays the growth of interest on microsurgery and medical applications of robotics has been so rapid. But the medical robots are only practical applications of the industrial robots. This paper identifies five general areas of advanced microsurgery based on the current technological background and expertise, and analyzes the motion, tool and accuracy with respect to microsurgery task, and proposed the criteria to evaluate micro-surgical manipulator. The analysis of microusrgery can be heplful to clarify some basic concept and design of micro-surgical manipulators. With these data we will alos propose an efficient in-parallel-platform manipulator having special kinematic structrue structure suitable for microsurgery.

A microsurgery telerobotic system has been developed to aid surgeons from physiological tremor, eye stram, hand tremor, contagious and radioactive hazard. This paper identifies four general areas of advanced microsurgery and analyzes the motion, tools, accuracy and applying forces with respect to microsurgery tasks, and proposes the criteria to design the microsurgical robot. The analysis of microsurgery can be helpful to clarify some basic concept and design of surgical robots. Based on this analysis results, we propose an efficient in-parallel-platform manipulator having a special kinematic structure suitable for microsurgery.

Breast deformity, in post-burn patients, is a common problem leading to lower self-esteem and reclusive behavior that impairs quality of life. The authors present the course of treatment of an 18-year-old immigrant girl who suffered second- to third-degree burns over approximately 20% of her total body surface area in her early childhood. The second- to third-degree burns were located on her right trunk and abdomen, as well as her right shoulder, neck, and right groin area. Since it was not offered in her home country, reconstructive surgery, including microsurgical breast reconstruction, was sought abroad. Due to the lack of available skin and soft tissue, a bilateral breast reconstruction with free transverse myocutaneous gracilis flaps was offered. This case illustrates one method of using microsurgery to address post-burn breast deformities in order to alleviate psychological suffering and improve quality of life.

Purpose: The purpose of the present retrospective cohort study was to investigate the incidence of sinus perforation during endodontic microsurgery and to assess healing of cases with sinus perforation. Materials and Methods: Clinical and radiographic records were collected from patients who were treated with endodontic microsurgery in the Microscope Center of the Department of Conservative Dentistry at Yonsei University College of Dentistry, Seoul, Korea, between March 2001 and January 2016. To determine the incidence of sinus perforation, all cases involving maxillary premolar and molar teeth were assessed, and cases with perforation of maxillary sinus during the procedure were counted. To assess the outcome of the endodontic microsurgery, cases with sinus perforation were recalled at least 1 year after surgery. Result: Two hundred and forty-nine maxillary premolars and molars were treated with endodontic microsurgery. Among these cases, 16 cases had sinus perforations. Overall incidence of sinus perforation was 6.4%. Thirteen cases with sinus perforation were followed up for 1 year after endodontic microsurgery. Outcome assessment revealed that 2 of 13 cases with sinus perforation had failed. The success rate of endodontic microsurgery with sinus perforation was 84.6%. Conclusion: Endodontic surgery performed using microsurgical techniques decreases the risk of sinus perforation. Predictable outcomes of endodontic microsurgeries and healing of sinus membrane can be expected with adequate treatment steps and careful periodic follow-ups in cases with maxillary sinus perforations.
