BACKGROUND: The facial bone has a complex structure compared to other bones, and various types of fractures can occur due to its characteristics. Among them, in comminuted fractures of anterior maxillary wall, multiple depressed and impacted bony segments cannot be reduced easily when performing internal fixation using plates and screws or wires, and inadequate restoration leads to a range of complications. This paper introduces an alternative technique using a resorbable mesh with fibrin glue to restore comminuted fractures of anterior maxillary wall. METHODS: Thirteen patients were diagnosed with comminuted fractures of anterior maxillary wall between March 2017 and February 2018 in the authors’ hospital. All patients with comminuted fractures of anterior maxillary wall underwent restoration using resorbable mesh with fibrin glue. The patients’ demographics, causes of facial trauma, mean operation time, length of hospital stay, follow-up period, and complications were recorded. RESULTS: No major complications and only one hypoesthesia of the skin area was noted. Three months after surgery, the hypoesthesia recovered completely. After surgery (mean, 3.9 months; range, 2–12 months), computed tomography showed that the bone fragments in all patients were fixed successfully in their anatomical places. CONCLUSION: In comminuted fractures of anterior maxillary wall, the use of a resorbable mesh with fibrin glue can be an advantageous and effective method for a successful restoration without complications.

Yonsei Dermatology celebrated its centennial in 2017, marking 100 years since Kung Sun Oh established the first Department of Dermatology and Urology in Korea in 1917. Following the footsteps of Kung Sun Oh, a pioneer of Korean dermatology, its members united and worked to provide the best medical service and achieve academic milestones in dermatology. Over the past hundred years, Yonsei Dermatology has played a pivotal role in the advancement of medical science and academia in Korea. The main activities of the department include medical care, education, and dermatologic research. Its research activities have encompassed a wide spectrum of dermatologic manifestations from skin immunology and pathology to introduction of newly developed treatment technologies. As Kung Sun Oh was the first Korean professor of dermatology at Severance Medical School and a passionate educator, we continue to serve his will by nurturing medical students and dermatology specialists to serve as global medical leaders. The Kung Sun Oh Memorial Lecture, first hosted in 1977, was the beginning of mutual international academic exchange in the field of dermatology in Korea. The memorial lecture has played a major role in advancing the academic status of Korean dermatological science by inviting distinguished dermatologists from around the world as guest lecturers. Yonsei Dermatology has played a key role in the history of modern medicine and dermatology in Korea over the last 100 years and continues to make an impact.

Epithelioid hemangioendothelioma (EHE) is a well-differentiated and rare vascular tumor. Systemic metastases are uncommon. Herein, we present a patient with skin metastasis of pulmonary EHE (PEH) that was treated by wide excision. A 76-year-old male was evaluated due to pulmonary thromboembolism and a solitary pulmonary nodule. A biopsy was performed and pathological examination of the mass confirmed EHE. No metastasis was observed. The patient returned to care approximately two years later due to a painful nodule in the right lower leg. A skin biopsy showed metastatic EHE from the lung. We used a safety margin of 1 cm based on clinical experience, because no prior case had been reported regarding the resection margin appropriate for primary cutaneous EHE and skin metastases of PEH. At four months after surgery, the patient recovered without complications or recurrence. Skin metastasis of PEH is extremely rare, and only two cases have been reported in the literature. In this case, we report a rare case of PEH with histologically diagnosed skin metastasis that was successfully treated by curative resection. It is expected that this case report will provide a helpful contribution to the extant data regarding PEH metastases.

PURPOSE: The reverse digital island flap is useful for the repair of various fingertip injuries. We present a modified surgical technique with skin strip elevation for the prevention of postoperative congestion. METHODS: From January 2005 to October 2015, we performed 31 reconstructive procedures for finger injury using a reverse digital artery island flap with and without skin strip retention. Patients' clinical characteristics, surgical outcomes, and complications were investigated. RESULTS: All flaps survived and there were no donor site problems. The mean follow-up time was 5 months (range, 3-8 months). In skin strip retention group, mild venous congestion was observed in 1 case, although it resolved spontaneously. Another case retained flexion contracture, and 2 patients had stiffness at the distal interphalangeal joint. Whereas, in no retention group, venous congestion was observed in 3 cases, 1 patient had partial flap necrosis and 2 patient suffer in flexion contracture at metacarpophalangeal joint. CONCLUSION: The reverse digital island flap procedure produces consistent results and is reliable for the treatment of fingertip injury. Our modified surgical technique of elevating the flap accompanied by skin strip retention helps prevent postoperative congestion.

PURPOSE: Self-inflicted wrist laceration is a common injury in the department of hand surgery. The aim of this study was to investigate the clinical characteristics and psychiatric features of self-inflicted wrist laceration using categorization according to wound severity. METHODS: We reviewed 71 patients from 2002 through 2012. All of the patients were grouped into four groups. Data regarding the following characteristics were collected: age, gender, size, structure involved, instruments used, history of previous self-inflicted injury, comorbidities in psychiatric and presentation of follow-up outpatient appointment to the department of plastic surgery and psychiatry. RESULTS: In these patients, approximately 64% of patients were female. About 80% of patients cut their wrist using a knife. And in grade 3-4 injury, percentage of glass injury was relatively high (22%), compared with other grades (3%). Unlike previous studies, patients in grade 3-4 tended to cut their wrist repeatedly. Focusing on psychiatric problems, approximately one quarter of patients had a previous history of self-infliction. In all patient groups, mood disorder was the most common disorder in patients who had a previous psychiatric disorder. But after operation, more than two thirds of patients had not visited department of psychiatry again. CONCLUSION: We identified some other differences among their characteristics. All patients in group also should be evaluated and surgically treated properly. A multidisciplinary approach is required for patients with wrist laceration due to self-injury in comparison to those with laceration due to other causes. Because many of them have previous self-injury experiences and psychiatric disease.

PURPOSE: Soft-tissue reconstruction in the knee area requires thin, pliable, and tough skin. The range of motion of the knee also acts as a limitation in using only local flaps for coverage. The author has successfully used various perforator flaps for soft tissue reconstruction around the knee while preserving its functional and cosmetic characteristics. MATERIALS AND METHODS: Out of the twenty patients assessed from April 2009 to March 2011, seven received anterolateral thigh perforator flaps, four received medial sural perforator island flaps, four received lateral supragenicular perforaor perforator flaps, and five received medial genicular artery flaps. The age of the patients ranged from 44 to 79 and the size of the defects ranged from 4x5 cm to 17x11 cm. Fifteen of the twenty patients had histories of total knee replacement (TKR) surgery. RESULTS: There were no flap losses in any of the twenty patients assessed. Two patients showed partial losses in the distal area of the flap, but were treated through careful wound care. One patient presented with pedicle adhesion at the drainage site from a past TKR, but it did not hinder the flap survival. Primary closure at the donor site was possible in nine patients, while split skin graft was necessary for the other 13. CONCLUSION: In soft tissue reconstruction of the knee, various perforator flaps can be used depending on the condition of the preoperation scar, wound site, and size. It also proved to provide better functional and cosmetic results than in primary wound closure or skin grafts.
