Tanzer reported microtia reconstruction using autogenous costal cartilage, thereafter so many plastic surgeons have tried various modification to get further refinement of reconstructed auricle. But the multiple stages of ear reconstruction required prolonged hospitalization and cost. In order to decrease the number of surgical stages and for the maximal convolution, we have employed a surgical procedure with three layered costal cartilage graft for the high profile auricle, concha formation and lobule transposition at the same time. However, it has still been difficult to reconstruct the tragus in cases of microtia that lack such component. We reconstructed the tragus using part of the microtic ear in addition to our above procedure simultaneously. This procedure is started with transposition of the lower two-thirds of the microtic ear to make lobule and then the upper third of the microtic ear is elevated as a chondrocutanenous flap which is then transposed 120-180degree C downwards to reposition at the area anterior to the conchal cavity. Using this technique, we have reconstructed 28 microtic ears. Adequate positioning of the auricle and tragus have been achieved and a more natural auricle obtained.

The prominent mandibular angle is one of the disfiguring features in the Oriental, commonly seen and considered to be unattractive. Because it gives a square and muscular facial appearance, its surgical correction is dine frequently as a modality of facial contouring surgery in the Oriental. The reduction mandibular angleplasty is not a simple surgical technique for the unexperienced surgeon. We adopted C-arm fluoroscopy as a method of identifying the osteotomy line for the beginners. The reduction mandibular angleplasties assisted by C-arm fluoroscopy were performed in 9 patients, providing symmetric and satisfactory results. Now we are sure that the reduction mandibular angleplasty assisted by C-arm fluoroscopy can be an accurate and safe method for the unexperienced surgeon, especially the patient with deep-seated prominent mandibular angle.

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.

PURPOSE: The aim of this study is to evaluate the value of preoperative MRCP prior to laparoscopic cholecystectomy by analysis of postoperative outcomes. METHODS: Between 2009.12~2010.12, 283 patients underwent laparoscopic cholecystectomy for treatment of benign biliary disease. Among these patients, 125 underwent preoperative MRCP and were classified as the MRCP group. The remaining 158 patients who did not undergo MRCP were classified as the non MRCP group. We compared perioperative data, including the rate of bile duct injury, operative complication, conversion rate, hospital stay, and hospital cost between the two groups. In addition, we analyzed preoperative MRCP findings, including common bile duct (CBD) stones and bile duct anomaly. RESULTS: Findings on pre-operative MRCP scan revealed silent CBD stones in five patients (4.0%) and bile duct anomalies were identified in 17 patients (13.6%). Three cases of bile duct injury occurred in the non MRCP group, whereas, no bile duct injury occurred in the MRCP group. No significant statistical difference in postoperative complication was observed in either group. Mean duration of operation was 50.5 (+/-30.4) minutes in the MRCP group, and 52.2 (+/-29.9) minutes in the non MRCP group (p=0.630). Post operative hospital stay was 2.1 (+/-1.4) days (mean) in the MRCP group, and 2.5 (+/-2.5) days in the non MRCP group. No statistical difference was observed between the two groups (p=0.110). CONCLUSION: MRCP may be useful for evaluation of bile duct anomaly and identification of hidden bile duct stones. However, this modality did not show statistical benefits for postoperative outcomes in patients who underwent laparoscopic cholecystectomy.

PURPOSE: The purposes of this study are to determine the degree of diagnostic consistency among the primary diagnosis in the emergency department (ED), abdominal multidetector computed tomography (MDCT) findings, and the final diagnosis at hospital discharge in elderly patients with non-traumatic acute abdominal pain; to describe common disease entities in these patients; and to determine the extent of agreement between management plans before and after abdominal MDCT. METHODS: We undertook the retrospective review of the charts of 109 patients, 65 years or older with non-traumatic acute abdominal pain. The measure of agreement between diagnostic phases and between planned and actual management was evaluated by Cohen's kappa statistic. RESULTS: Value of the kappa statistic for agreement between primary diagnosis in the ED and final diagnosis at hospital discharge and between MDCT findings and final diagnosis were 0.408 and 0.776, respectively. The most common MDCT findings were biliary disease (17.4%), ischemic bowel disease (16.5%) and malignancy (16.5%). At the time of final diagnosis at hospital discharge, the order of frequency was malignancy (16.5%), biliary disease (15.6%), and ischemic bowel disease (12.8%). The degree of agreement between before and after abdominal MDCT in management plans was 0.154. CONCLUSION: Abdominal MDCT can skew diagnosis and management plans significantly in elderly patients with nontraumatic acute abdominal pain.

Kabuki (Niikawa-Kuroki) syndrome was first reported by Niikawa et al(1981). The faces of the patients are similar to the make-up of traditional Japanese Kabuki actors: long palpebral fissures, an ectropium of the lateral third of the eyelids,and arching eyebrows with sparse lateral halves. Craniofacial findings include a depressed nasal tip, short nasal septum, large and prominent ears, and micrognathia. Other main features area mild to moderate mental deficiency, short stature, skeletal and dermatoglyphic abnormalities, including prominent finger tip pads. Oral anomalies are common in KS(over 60percent) and include abnormal dentition, widely spaced teeth, cleft palate or lip, high vault of palate, hypodontia, conical incisors, screw driver-shaped incisors and ectopic upper 6-year molars. The increased occurrence of cleft lip and palate or the development of a high vault of palate has been described by a number of authors. This condition is believed to be common in Japan, but has been reported from other parts of the world. The objective of this presentation is to report a case of this syndrome in six-year-old girl, with characteristic findings.

Journal of the Korean Society of Emergency Medicine 2004;15(6):492-497
PURPOSE: This study aimed to investigate the injury patterns of unrestrained front-seat passengers in traffic crashes. METHODS: Using 2000~2003 data from the Jeonbuk Provincial Police Agency and medical-chart review, we estimated the relationship between crash patterns and individual variables, such as age, sex, Injury Severity Score, prehospital care, outcome, injury types, passenger seats, velocity, and alcohol consumption. We also investigated whether the Injury Severity Score correlated with crash patterns, passenger seats, velocity, prehospital care, and alcohol consumption. RESULTS: The mean Injury Severity Scores in frontal and rollover crashes were 15.0(+/-0.7) and 22.6(+/-3.3), respectively and the difference was statistically significant (p<0.05). The mortality rate was higher in rollover crashes than in frontal crashes (p<0.05). The most common type of injury in unrestrained passengers during frontal and rollover crashes was head and face injury. In addition, chest and lumbar spine injuries were more common in rollover crashes than in frontal crashes, and this difference had statistical significance (p<0.05). The Injury Severity Score correlated with the crash patterns (rho=0.25, p<0.01), overspeeding (rho=0.44, p<0.01), prehospital care (rho=0.25, p<0.01), and alcohol consumption (rho=0.18, p<0.05). CONCLUSION: We estimate that rollover crashes are associated with an increased risk of injury to and death for frontseat passengers compared to frontal collisions. Knowledge of injury mechanisms should help emergency physicians to promptly evaluate all areas at risk, as well as the potential for fatality.

Journal of the Korean Society of Emergency Medicine 2006;17(1):39-44
PURPOSE: This research investigated the extent of telephone advisers'satisfaction with respect for giving telephone advice and the working environment at 12 emergency medical information centers. METHODS: During July 2004, we approached 12 emergency medical information centers. We sent a three page postal questionnaire to each worker. The questionnaire had three parts questions about the working environment, giving telephone advice, and demographic characteristics. RESULTS: The response rate was 81.8%. The hundred (100) workers selected for this study were telephone advisers. As to the working environment, they were unsatisfied with the small workspace and the poor ventilation. Sixty-three (63) workers had telephone advice education. They felt that 'callers' overstatements' and 'not seeing the patients' left them stressed when giving telephone advice. They anticipated that 'protocol' and 'education about medical knowledge' were necessary for improving telephone advice. Seventy-three (73) workers had experienced burnout syndrome. CONCLUSION: Based on this survey on the extent of satisfaction with giving telephone advice and with the working environment, we think that improvements in the working environment and in the professional education for telephoneadvice skills are necessary. Also, we suggest that education to improve advisers'medical knowledge, development of advice protocols, and a program to prevent and manage burnout syndrome are required for enhanced work satisfaction in the future.

A healthy 72-year-old male was referred to the emergency department (ED) for removal of a foreign body (FB) in the right bronchi from a local medical clinic. The FB was a dental part measuring 5×15 mm in size, which had been accidently aspirated into the lung during a dental procedure. On arrival at the ED, he only complained of mild chest discomfort, and there were no abnormal findings in on physical examination. ED physicians prepared bronchoscopic FB removal while the patient rested in bed. During the wait for bronchoscopy, the patient felt discomfort in the chest and epigastric area, and then he coughed forcefully and at the same time, epigastric thrust was performed with his fist. After several strong coughs with epigastric thrusts, the FB was expelled from his mouth. Chest roentgenogram showed no FB, and the patient was discharged from the ED with no complications. Bronchoscopy has been the only treatment option for bronchoscopic FB, and self-removal of FB is rare. This case report may be helpful to understanding a possible mechanism of self-clearance of FB in some healthy adult patients with a small-sized endobronchial FB.
