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.

PURPOSE: To compare contrast sensitivity and color vision after implantation of a clear intraocular lens (IOL) and a yellow-tinted IOL in diabetic retinopathy patients. METHODS: In the 50 eyes of 25 diabetic patients with non-proliferative diabetic retinopathy, clear IOLs were implanted in 25 eyes, and yellow-tinted IOLs were implanted in 25 fellow eyes. Three months after the surgery, contrast sensitivity function was measured with a vision contrast test system, and color discrimination was tested using the Farnsworth Munsell 100-hue test. RESULTS: Eyes implanted with yellow-tinted IOLs had significant differences in contrast sensitivity values compared to those of fellow eyes implanted with clear IOLs in both the moderate diabetic retinopathy group (6.0 cycles per degree) and the severe diabetic retinopathy group (throughout all spatial frequencies except 12.0 cycles per degree). The yellow-tinted IOL did not modify chromatic discrimination compared with that of the clear IOL. In the blue-yellow axis error score, however, there were significant differences between the clear IOL and the yellow-tinted IOL. CONCLUSIONS: With progressing diabetic retinopathy, the yellow-tinted IOL provided better contrast sensitivity than the clear IOL. The yellow-tinted IOL improved color vision in the blue-yellow chromatic axis without causing chromatic discrimination defects.
