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.

During a 2-year period microsurgical vasovasostomies using permanent silicone stent(c-shaped stent with 0.6mm slit, 5mm in length, 0.8mm in outer diameter, 0.5mm in inner diameter) were performed in 30 patients for vasectomy revesal. The stent-assisted vasovasostomy(SVV) was intended to decrease the technical demand, the time requirement and the occurrence of reobstruction due to postoperative stricture. The effectiveness of the permanent silicone stent for vasovasostomy was compared with that of microsurgical two-layered vasovasostomy(VV). Sperms were present in all the ejaculates of the 25 men on semen analysis 1-2 months after SVV. Pregnancy occurred in 10 of 22 couples(45.5%) during 2-24 months of follow-up and it took 4-10 months(average 7.2 months) to get pregnant. Average operation time for the VV was 150 minutes and that for the SVV 125 minutes. Among 12 men who had sperms in the ejaculates 1-2 months after SVV, 4 revealed azoospermia 3-17 months postoperatively. Among the 4 patients with postoperative azoospermia, 2 underwent reoperation. On histopathologic examination, previously anastomsed sites showed obliterated lumen of the stent and strictures of vas proximal and/or distal to the stents due to granulation tissues. In conclusion, the SVV was not more efficacious in terms of patency and pregnancy rate than the VV.

The Z-plasty has been known as a most common surgical treatment of congenital circumferential constriction band syndrome of the hand. There were thirteen patients of congenital circumferential constriction band syndrome of the hand. All patients underwent Z-plasty under microscope. we did microsurgical dissection to minimize vascular, neural and lymphatic injury, and then considering secondary correction and scar contracture, tried to preserve as much subcutaneous fat and skin flap as possible without any excision. There were less skin necrosis and lymphedema as a result of vascular compromise. Using microscope offers several advantages. First, preventing vascular, neural and lymphatic injury. Second, getting an accurate suture approximation. finally, preserving as much subcutaneous fat and skin flap as possible without any excision. The outcome of digit growth and contour can be excellent than we expected. As a results, we believe that correction of congenital circumferential constriction band syndrome of the hand under the microscope have better results.

The ability for tissue transfer based on microvascular anastomosis has created a revolution in microsurgical free tissue transplantation. The advantages of cutaneous flaps are that they are soft, durable and provide a good cosmetic reconstruction and muscle flaps have a more vigorous blood supply and a longer, larger vascular pedicle than cutaneous flaps. From June 1992 through May 1997, 68 patients had received reconstructive microsurgery in the lower extremity at Department of Orthopedic Surgery, Chonbuk National University Hospital. The results were as follows. 1. The age distribution was from 15 years of age to 67 and male were 59 cases and female 9 cases. 2. The most common cause was traffic accident(54 cases, 79.4%) and followed chronic osteomyelitis(9 cases, 13.2%), industrial accident(3 cases, 4.4%), burn(1 case, 1.5%) and farm injury(1 case, 1.5%). 3. Latissimus dorsi myocutaneous flap were 25 cases(36.8%), rectus abdominis muscle flap 21 cases(30.9%), gracilis muscle flap 10 cases(14.7%), dorsalis pedis flap 9 cases(13.2%), groin 2(2.9%) and vascularized iliac osteocutaneous flap 1(1.5%). 4. 61 cases(89.7%) of 68 cases were survived and the exposed vital tissues and bones were covered and revealed good cosmetic results.

Background First suggested by Brent in 1979, the pocket principle is an alternative method for patients for whom a microsurgical replantation is not feasible. We report the successful results of a modified palmar pocket method in adults. Methods Between 2004 and 2008, we treated 10 patients by nonmicrosurgical replantation using palmar pocketing. All patients were adults who sustained a complete fingertip amputation from the tip to lunula in a digits. In all of these patients, the amputation occurred due to a crush or avulsion-type injury, and a microsurgical replantation was not feasible. We used the palmar pocketing method following a composite graft in these patients and prepared the pocket in the subcutaneous layer of the ipsilateral palm. Results Of a total of 10 cases, nine had complete survival of the replantation and one had 20% partial necrosis. All of the cases were managed to conserve the fingernails, which led to acceptable cosmetic results. Conclusions A composite graft and palmar pocketing in adult cases of fingertip injury constitute a simple, reliable operation for digital amputation extending from the tip to the lunula. These methods had satisfactory results.

Purpose: Microsurgical exercise has been performed with rat femoral vessels. But, it needs animal laboratory, anesthesia and its keeping facilities. Materials and Methods: Ten human placentas were studied for suitability in a microvascular exercise. The size and useful length of vessels were measured, and various microvascular anastomoses were performed. Result: The human placenta has many vessels traversing its fetal surface. A variety of sizes are available down to vessels of diameter 1 mm and up to vessels of diameter 6.5 mm (1.0

Microsurgical vascularized bone transfer has the disadvantages of limitation of available donor sites, loss of donor function, and the possibility of donor site defects or deformity. To overcome these shortage of current microsurgical tissue transfer, the method of creating the neovascularized free flap has been introduced. Potentially, this technique must be an innovation in providing the free vascularized bone grafts that are not limited by natural vascular anatomy. But, as could be imagined technique resulted in unavoidable donor bone defect and additional operation for harvesting the autologous bone. The purpose of this study was to evaluate the efficacy of demineralized allogeneic bone as a possible substitute for autologous bone in fabricating the neo-osseous flap. By histologic, microangiographic and radioisotope method, the viability and vascularity of neo-osseous flap, which has been fabricated using allogeneic bone or autologous bone, was assessed in rat model. After 6 weeks, demineralized allogeneic bone showed consistent bone formation and neovascularization. The clinical and microscopic findings of demineralized allogeneic bone group were inferior to those of autogenous bone with regard to bone regeneration. The amount of bone blood floow per dry weight of demineralized allogeneic bone group was significantly higher than that of autogenous bone, even higher that of control intact iliac bone. In conclusion, findings supported that allogeneic bone could be the potential substitute for autologous bone source in creating a prefabricated neo-osseous flap.

In the high radial nerve palsy caused by displaced humeral shaft fracture, radial nerve have to be explored in the fracture site. 5 cases of the ruptured radial nerve at the fracture site of the humerus from January 1993 through January 2005 were treated at first by open reduction and internal fixation with plates and screws fixation and then defective radial nerves were grafted with autogenous sural nerves by microsurgical epineurial and or perineurial neurorrhaphy. At average 30.4 months follow-up, 5 cases were recovered from motor and sensory deficit with solid bony union of the humerus shaft fracture. Authors have confirmed that ruptured radial nerve in the humerus shaft fracture grafted with autogenous sural nerve with microsurgical epineurial and or perineurial neurorrhaphy would be expected good motor and sensory recovery.

The auricle is easy to be amputated in the face due to its protruding position. When facial parts are amputated, the mechanism of injury usually involves some form of avulsion, which damages these fragile vessels over a distance and renders them unsuitable for anastomosis. Replantation of the ear remains a challenging problem because of the tiny vessels and the paucity of adequate veins for anastomosis. Reattachment as a composite graft of the total or subtotal amputated ear is unreliable. Microsurgical replantation can be performed in a minority of cases because of technical difficulties and long operation time. In this article, the authors report two case of a successful ear replantation of completely amputated auricle. Only one artery and one vein were anastomosed in first case. In the other case one artery was anastomosed without vein. Instead of venous repair, multiple incision was done with leech application therapy. and the outcome was successful. In spite of the technical difficulties and long operation time, microsurgical replantation of amputated ear is better than other reconstructive method or reattachment without microsurgery.

Mobile computing devices (MCDs), such as smartphones and tablets, are revolutionizing medical practice. These devices are almost universally available and offer a multitude of capabilities, including online features, streaming capabilities, high-quality cameras, and numerous applications. Within the surgical field, MCDs are increasingly being used for simulations. Microsurgery is an expanding field of surgery that presents unique challenges to both trainees and trainers. Simulation-based training and assessment in microsurgery currently play an integral role in the preparation of trainee surgeons in a safe and informative environment. MCDs address these challenges in a novel way by providing valuable adjuncts to microsurgical training, assessment, and clinical practice through low-cost, effective, and widely accessible solutions. Herein, we present a review of the capabilities, accessibility, and relevance of MCDs for technical skills acquisition, training, and clinical microsurgery practice, and consider the possibility of their wider use in the future of microsurgical training and education.
