The basic technique for total reconstruction of the microtia was established by Tanzer, who utilized autologous rib cartilages for constructing the auricular framework. In order to decrease the number of surgical stages and to achieve maximal convolution, we employed a surgical procedure with simultaneous three layered costal cartilage grafting for the high profiled auricle, concha formation and lobule rotation. However, we performed ear elevation as an additional procedure for some patients who had decreased helical height due to absorption of cartilage framework or postoperative trauma and who had wanted to wear the spectacles or to have more natural appearance of auriculocephalic sulcus. From August 1988 to October 1997 we had performed surgeries for the ear elevation of 58 patients in 177 patients with total ear reconstruction, using various elevation methods; skin graft, local flap, and local with costal cartilage block. When the ear elevation was performed with skin graft, postoperative contraction of the grafted skin was inevitable. In cases with two skin flaps, it was difficult to stabilize and maintain the correct projection of the constructed ear. So we elevated the reconstructed ear by utilizing a costal cartilage block, two skin flaps to cover the posterior region and skin graft. We conclude that the local flap with costal cartilage block is one of the most favorable methods in ear elevation which can maintain the adequate projection and make natural looking auriculocephalic sulcus.

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

Ameloblastic fibrosarcoma is an extremely rare variety of odontogenic tumor. It has not previously been reported in Korea. The tumor is composed of benign odontogenic epithelium with a mesenchymal part which exhibits the histologic features of fibrosarcoma. We have reported a case of amloblastic fibrosarcoma of the mandible in a 26-year-old man with swelling of right mandible for 2 weeks. The tumor showed yellowish ill-demarcated ulcerating mass involving right premolar and molar area. Light microscopy revealed irregularly arranged strands and islands of odontogenic epithelium surrounded by abundant mesenchymal tissue with the feature of fibrosarcoma. The fibrosarcoma cells were strong positive on immunostain for vimentin and ameloblastic cells were weakly positive for cytokeratin. S-100 and CEA were negative in both epithelial and sarcoma cells. The sarcoma cells were corresponding to fibroblasts on the electron microscopy with abundancy of RER and mitochondria and covering of basal lamina. Two types of virus like particles were distributed in the cytoplasm and nuclei of sarcoma cells. We treated the patient with surgery and chemotherapy. The recovery was uneventful and the prognosis is under observation.

Pneumatosis cystoides intestinalis is a rare condition which is characterized by multiple gas-filled cysts of varying sizes in the wall of the gastrointestinal tract. In 85% of the cases, it is associated with gastrointestinal, pulmonary, and connective tissue diseases or with other conditions. In about 15% of the cases, the etiology remains obscure. In most cases, the prognosis is poor, so early diagnosis and treatment are required. We report two cases of primary pneumatosis cystoides intestinalis with portal venous gas which were associated with alcoholism and diabetes mellites and which were complicated by pneumoperitoneum and panperitonitis.

Under the assumption that people go through stages in making dietary behavior change, this study was attempted to apply the stages of a change model for fat intake by examining the associations of social psychological variables with stages of change in dietary fat reduction. Derived from social psychological theories, 10 social psychological variables on motivational beliefs(6), social influence(3) and self-efficacy(1) related specifically to selecting every day diets low in fat were constructed. Fat and energy intakes were assessed by a short form semi-quantitative food frequency questionnaire. The associations of stages of change with motivational beliefs, social influence, and self-efficacy variables and energy and fat intakes were assessed in 333 female adults from large cities in Korea. Dietary stage groups differed significantly on most of the social psychological variables in ways predicted by theory. Motivational factors that lead to a psychological state of readiness to take action were important in the early stages of the dietary change process. Social influences were more important in the stages as people decide to take action. Self efficacy and motivational beliefs, particularly, reduction of perceived barriers were important in maintaining fat reduction behavior. The results of our study indicate differences in stages of change in fat reduction behavior in terms of nutrient intakes and social psychological correlates and suggests that adding a time dimension to social psychological models increases our understanding of dietary change, which assist us in designing nutrition education interventions that are more appropriately targeted by stage of change.
