It is common to find a nose with a hump, lower nasal tip and a radix among Koreans. A common procedure as an aesthetical improvement for such feature, involves rasping of the hump, while lifting the tip and the bridge at the same time. As for the hump, en bloc resection is a well-known, traditional surgical method, but it may cause an open roof deformity, which leads to a high possibility of infection if dorsal augmentation using silicone was performed through it as it connects the nasal cavity and dorsum. To overcome this complication, the hump on the bony portion and cartilaginous has been improved by a modified autospreader graft. Also, the graft can also be used for tip-plasty in dorsal augmentation using silicone, septal extension graft, strut and onlay graft. As a result of constant monitoring for a year, the reformation of the hump and infection was not found.

In shape and dimensions, the tibial plateaus are asymmetric with the larger medial tibial plateau and both have a posterior inclination with respect to the shaft of the tibia. Maximizing tibial coverage is an impotant consideration in total knee arthroplasty to provide stahility and load transfer and to improve long-term survival rate of the implants. Most tihial tray designs are symmetric, but several asymmetric designs are available. We evaluated the proximal tibial resection surface during total knee aithroplasty to delineate the tibial plateaus in korean. After tihial bone cut during 100 TKA procedures, the outline of tibial resection suiface was traced and rotational axis of true tibial component was marked intraoperatively. A line was drawn at the maximal anteroposterior (AP) diameter of lateral tibial condyle with parallel to rotational axis of component, and then a transverse axis was drawn at the midpoint of maximal AP diameter of 1ateral tibial condyle. Anteroposterior 10, 20, 30., 40% and midpoint from the media1 and lateral peripheries were calculated manually. The average AP medial 10, 20, 30 and 40% dimensions were 34.7, 43.8, 48.0 and 43.2mm, respectively. The average AP lateral 10, 20, 30 and 40% dimensions were 30.2, 38.4, 42.0 and 40.9mm, respectively. The ratio of medial/lateral AP dimensions 10, 20, 30 and 40% from periphery were 116.9, 114.7, 114.5 and 106.4%, respectively. From these data, we know the asymmetry of the proxirnal tibia1 plateaus in korean. We hope that rnore data will be ohtained in multicenter studies and it will help us to select tibia1 tray and to design the tibial component in korean. But, more accurate standard measures will he need to minimize an error of measurements.

Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

PURPOSE: This study was aimed to review findings of gray-scale ultrasonography and to assess the diagnostic value of the resistive index (RI) in patients with acute epididymitis by comparing with that in normal volunteers. MATERIALS & METHODS: Gray-scale ultrasonogram was reviewed in nine patients with acute epididymitis for echogenicity, size and reactive hydrocele. Normal values of resistive index (RI) were obtained in 20 epididymides from 10 volunteers (aged 20-28, mean 23.7). Nine patients of epididymitis (aged 18-67, mean 37.2) were examinated with color Doppler sonography and RI was measured at 11 sites on epididymal arteries. For the prediction of acute epididymitis, accuracy, sensitivity and specificity were calculated at the cut-off value of RI in 0.65 and 0.70. RESULTS: Gray-scale ultrasonography showed echogenicity that was variable among the 9 cases (hype- rechoic 2 cases, isoechoic 2, hypoechoic 5), enlargement of epididymis in 8, and reactive hydrocele in 8 cases. Normal volunteers displayed color Doppler signals in 14 out of 20. The range of RI in normal volunteers were between 0.64 and 1.00 (mean, 0.79 +/- SD 0.10). In patients with acute epididymitis, color Doppler signals were detected in all patients. The range of RI in epididymitis were 0.40-0.68 (mean, 0.56 +/- SD 0.10). At cut-off RI value of 0.65, accuracy was 88%, sensitivity 81.8%, and specificity 92.7%. At cut-off value of 0.70, accuracy was 92%, sensitivity 100%, and specificity 85.7%. CONCLUSION: In addition to the findings of gray-scale ultrasonography, resistive index and color flow changes are valuable in diagnosing acute epididymitis.

Arteriovenous fistulas of head and neck, especially the external carotid artery are uncommon lesions usually of traumatic origin. They also may be spontaneous, inflammatory, or congenital origin. They maybe accompanied by symptoms and signs such as pulsatile tinnitus, pulsatile mass, palpable thrill, and machine like bruit. Recently, we experienced a case of spontaneous arteriovenous fistula of external carotid artery, treated by coil embolization. The patient noticed pulsatile tinnitus in the left posterior auricular area and left upper neck area. She had no history of head trauma. External carotid angiogram showed fistula between the branches of the external carotid artery (occipital artery, middle meningeal artery, posterior auricular artery) and the internal jugular vein. The fistulas were successfully controlled by coil embolization.

Ceftriaxone is a commonly used antibiotic due to some of its advantages. Reversible gallbladder (GB) sludge or stone has been reported after ceftriaxone therapy. Most of these patients have no symptom, but the GB sludge or stone can sometimes cause cholecystitis. We experienced two patients who had newly developed GB stones after ceftriaxone therapy for diverticulitis and pneumonia, and this resolved spontaneously 1 month after discontinuation of the drug. Awareness of this complication could help to prevent unnecessary cholecystectomy.
