We report 2 cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap. In these cases, the main points to cover the defects were as follows: 1. For the contour of zygoma and maxilla, it was well preserved without bone graft which was not used for second stage reconstruction. In first case, for application of artificial eyes and in second case, for operation after full development. 2. For the drainage of paranasal sinuses, we made the nostril with skin graft, and it was well preserved without any complications during follow up. 3. It was sufficient to cover the defect with latissimus dorsi muscle well designed before surgery and thick enough to fill the defect. 4. In second case, the remained defect of palate and maxilla was not covered for the appropriate reconstructions after full development. In conclusions, we experienced two cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap without any complication and with good results.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Rips, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From March to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.

Lipomas are common soft tissue that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma, is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.

In the treatment of malleolar fracture, anatomical reduction and rigid internal fixation are essential to prevent the complications such as infection, malunion or nonunion, traumatic arthritis, skin necrosis and joint contracture. But it is often difficult to obtain rigid fixation for medial malleolar fracture because of its comminution or thin cortex with osteoporosis. Generally, two operative methods are available for medial malleolar fracture, which are malleolar lag screw fixation and tension band wiring. The purpose of this paper is to analyze which operative method is better for anatomical reduction and rigid fixation and has less postoperative complications for medial malleolar fractures. From March 1992 through March 1995, 88 patients had undergone surgical intervention for medial malleolar fractures. The patients were divided into 2 groups according to operative method for medial malleolar fracture. For one group, malleolar lag screw together with or without a K-wire was used in 48 patients, and for the other group, tension band wiring was used in 40 patients. The average follow-up periods were 14 months in screw fixation group and 13 months in tension band wiring group. The average union time were 15.4 weeks (8-17 weeks) in screw fixation group and 12.2 weeks (6-15 weeks) in tension band wiring group. 27 cases (56%) showed excellent result in screw fixation group and 30 cases (75%) in tension band wiring group. In the patient over 50 years old, 2 (15%) in 13 cases showed excellent result of screw fixation group, while 5 (45%) in 11 cases of tension band wiring group. We concluded that tension band wiring is a better method for medial malleolar fracture to obtain early union and to prevent postoperative complications, especially in the elderly patient.

A 54-year-old diabetic man presented to the hospital with shock and bradycardia. His initial estimated left ventricular ejection fraction (LVEF) was 15% and the electrocardiogram showed a junctional escape rhythm with a wide QRS complex and no P wave. Intensive supportive therapy was initiated after inserting a pacemaker and starting extracorporeal membrane oxygenation. A myocardial biopsy confirmed acute lymphocytic myocarditis with extensive myocyte necrosis, and cardiac transplantation was planned. However, the patient survived without transplantation after vigorous hemodynamic support for 2 weeks. After discharge, he had limited activity for 4 months due to dyspnea caused by a reduced systolic heart function (LVEF, 21%) with a junctional escaped beat. His systolic function recovered markedly 6 months after stopping the hemodynamic support, with the presence of a P wave and narrowed QRS complex.

We investigated the overall survival rate after pulmonary metastasectomy in the bone and soft tissue sarcoma and the available prognostic factors related with the survival rate after pulmonary metastasectomy. Between 1986 and 1995, 9 patients (median age 32) with bone and soft tissue sarcoma with pulmonary metastasis were managed in the Catholic University of Korea. Until the final follow-up in May 1996, 6 patients have died of disease and their mean survival period was 28 months (9- 58months). The actual 5-year survival rate by Kaplan-Meier method was 33%. Prognostic factors such as tumor free interval, number of metastatic lesion, postoperative chemotherapy and histologic grade were analyzed. Three patients who had the tumor free interval over 3 years were alive (mean survival period: 52.6 months), whereas six patients who had the tumor free interval less than 3 years were dead (mean survival period: 19 months). Out of four patients with low grade tumor, three patients were alive with average 39.2 months survival period, whereas five patients with high grade tumor were all dead with average 19.2 months survival period. These results suggested that pulmonary metastasectomy in bone and soft tissue sarcoma may prolong the survival rate. The long tumor free interval, histological low grade and soft tissue sarcoma may influenced on prolonged survival rate. However, number of metastatic lesion or postoperative chemotherapy has not influenced on the survival rate.

Finger injuries are becoming more common with the increasing use of mechanical industrial and household appliances. Among the hand injuries, amputation is the serious disaster to the patient. Recently, application of microsurgical technique to the reattachment of amputated digits has been common clinical procedures. We performed microsurgical replantation to the 75 patients with 102 digits from March in 1986 to February in 1988. The following results were obtained. 1. The most common age distribution was third decade and male to female ratio was about 5:1. 2. The ratio of right to left hand was about 1:1 but the dominant to non-dominant hand was about 2:1. 3. The index finger was most commonly injured and the next was middle finger. 4. The most common type of the injuries was the crushing injury and the most common vector was a kind of pressor. 5. The anesthesia was performed in equal ratio between the general and regional anesthesia. 6. The survival rate of micro-replantation to the injuries of the zone II was 77.8% and zone III was 80%. 7. The functional result after replantation at zone II was better than zone III. 8. Micro-replantation was performed in any case of the type of the injury, the severity of crushing and the ischemic time, and the patients requirement was an important factor.
