Liver transplantation is definitive treatment for the patients suffering from hepatitis, severe liver cirrhosis and liver cancer. In these patients, systemic infections under immunosuppression may occur easily. Therefore, primary object of dental treatments before liver transplantation is absolute removal of oral infection source. In addition, comprehensive dental management plan is essential for success of liver transplantation. The present study has been performed to investigate decayed, missing and filled permanent teeth index(DMFT index), degree of oral hygiene, past medical history, need of dental treatment, completion of dental treatment need and time interval between dental visit and operation date of liver transplantation in liver transplant candidates. Obtained results were as follows; 1. Decayed teeth of the patients were 2.68, missing teeth were 4.02 and filled teeth were 3.42. DMFT index was 10.12. 2. Twenty percents of patients showed moderate to severe food impactions, 42.2% of patients had moderate to heavy calculus and 37.8% of patients displayed gingival inflammation with swelling. 3. Patients needed periodontal treatments more than any other dental treatments. Periodontal treatments were needed for 88.9% of patients, operative & endodontic treatments were 46.7% of patients and 33.3% of patients needed for oral & maxillofacial surgical treatments. 4. Among 90 patients, time interval between scheduled operation date of liver transplantation and dental visit was within 2 weeks for 32.2% of patients, within 1 week for 20.0% of patients. In conclusion, most liver transplant candidates needed dental treatments for removal of potential infection sources. However because of insufficient interval between dental visit and operation date, they had taken liver transplantation procedures without comprehensive dental management. Development of preventive and comprehensive dental management program is mandatory for these patients. Cooperative interdisciplinary management will play a positive role for successful liver transplantation.

Purpose: We sought to determine the appropriate management modality for clavicle fracture through the review of current literature. Materials and Method: This article provides an overview of the knowledge regarding clavicular fracture in adults, including epidemiology, classification, surgical indication, current technique, and results. We also addressed recent debates: the range of the surgical indication for mid-clavicular fracture and the introduction of anatomically precontoured plate as a new treatment modality. Result and Conclusion: Nonsurgical treatment has been regarded as the first choice in the management of clavicle fractures. Quite recently, mounting evidence has shown that adverse outcomes, after a nonsurgical treatment, such as nonunion and malunion, were more prevalent than previously assumed. Accordingly, the indications for surgical fixation appear to be broadening. However, given that the ideal treatment option remains to be determined, the appropriate treatment of clavicle fractures should be tailored based on careful assessment of individual patient's data and preference.

Purpose: This study was conducted to determine the usefulness of ultrasonography in evaluating callus formation in radiologically suspected nonunion or delayed union of clavicle fractures during conservative management. Materials and Methods: Six male patients and one female patient (average age: 38.3 years; range: 7 to 70 years), whose conservatively managed clavicle fractures were suspected of nonunion or delayed union, were examined with ultrasonography. If callus formation was detected, the patient continued to receive conservative management. If callus formation was not detected, the patient received operative management. Results: Six patients, in whom callus formation was observed ultrasonographically, continued to receive conservative management. The final simple radiographies of their fractures showed complete unions. One patient, in whom no callus formation was observed ultrasonographically, received operative management. In that patient, there was no operative finding of any fracture healing. Conclusion: Ultrasonography is a useful tool for evaluating callus formation in clavicle fractures suspected of nonunion or delayed union during conservative management. Ultrasonography can be used to avoid unnecessary surgery.

Purpose: To evaluate the efficiency of arthroscopic treatment for infected total knee arthroplasty (TKA), and to investigate the factors affecting the outcomes. Materials and Methods: We analyzed 17 cases which underwent arthroscopic treatment to treat infection after TKA. After confirming infection by hematologic examination and analysis of joint fluid, we performed arthroscopic debridement, synovectomy and irrigation with normal saline mixed with antibiotics. Through routine examination after operation, we checked failure of treatment or recurrence of infection. If there is no recurrence until 2 years after the operation, we considered it as a success of treatment. Results: Of the 17 cases taken arthroscopic treatment, 13 cases were treated successfully with primary arthroscopic treatment only, but 4 cases had to undergo re-operation because of persistence or recurrence of infection. Analyzing the factors affecting the results, we found that symptom duration of the re-operation group is longer than the treated group after arthroscopy (p<0.05). Conclusion: Arthroscopic treatment can be effective when we performed appropriate selection of patients, careful and extensive arthroscopic irrigation and debridement, and suitable use of antibiotics. However, we have to do early arthroscopic surgery as soon as possible when infection after TKA is suspected.

후두암의 치료는 병변의 위치, 크기 등에 따라 치료방법이 다양하고 그 예후 또한 상이하다. 일반적으로 초기 후두암에서는 수술이나 방사선 요법이 비슷한 치료결과를 보이고, 진행된 후두암에서는 수술적 치료가 더 좋은 예후를 나타내는 것으로 알려져 있으나 발성장애를 초래하는 경우가 대부분이다. 저자들은 1986년부터 1990년까지 5년간 강남성모병원에서 후두암치료를 받았던 환자 81명을 대상으로 치료방법에 따른 음성보존 성적을 분석하였다. 1. T1 성대암 환자 18명중 16명 (88.9%)에서 방사선치료 또는 수술로써 음성을 보존할 수 있었다. 2. T2 후두암 환자 11명중 6명은 수술후 음성보존이 가능하였다. 3. 진행암환자 (T3, T4) 50명중 33명에 대해 수술을 시행하였고 이중 16명(48.5%)은 후두부분 또는 근전적출술 및 기관-식도 누공술에 의해 음성기능을 보존할 수 있었다. 4. 진행암환자에서 유도화학요법과 방사선치료의 병용요법만을 받은 17명 모두 6개월 이내에 재발하였고, 수술 혹은 수술과 방사선 치료를 병용한 33명중 27명이 최소한 6개월 이상 평균 2년 이상의 무병상태였다. 5. 후두부분 또는 근전적출술은 총 81명중 28명에서 시행되었고 그중 5명 (17.9%)에서 재발하였다.

Purpose : Rarity of olfactory neuroblastoma makes it difficult for treating Physician to Practice with a consistent protocol. This study is peformed to analyze our experience with various treatment modalities for patients with olfactory neuroblastoma. Discussion includes review of some recently published literatures. Methods and Materials : Between June of 1979 and April of 1997, 20 patients were treated under the diagnosis of olfactory neuroblastoma at Seoul National University Hospital. There were 14 male and 6 female patients. Age at initial treatment ranged from l3 to 77 years with median or 24 years. fifteen or 20 patients had Kadish stage C. They were treated with various combinations of surgery, radiation therapy and chemotherapy; surgery+postoperative radiation therapy+adjuvant chemotherapy for 2 patients, surgery+postoperative radiation therapy for 6, neoadjuvant chemotherapy+surgery for 1, surgery+adjuvant chemotherapy for 1, surgery only for 2, neoadiuvant chemotherapy+ radiation therapy for 3, radiation therapy+adjuvant chemotherapy for 1, radiation therapy only for 3, and no treatment for 1 patient. Results : Follow-up ranged from 2 month to 204 months with mean of 39.6 months. The overall 5- and 10-year survival rates are 20% and 10%, respectably. Four patients are alive at the time of data analysis. One of four living patients was treated with radical surgery, postoperative radiation therapy and adjuvant chemotherapy, two patients with radical surgery and postoperative radiation therapy, and one with radical surgery only. Conclusion : Multidisciplinary approach, including radical surgery, pre- or post-operative radiation therapy and chemotherapy, should be addressed at the initial time of diagnosis. Although limited by small number of the patients, this study suggests importance of local treatment modality, especially radical surgery in the treatment of lofactory neuroblastoma.

Purpose To evaluate the MRI findings and clinical factors that are characteristic of patients who ultimately undergo surgery for medial epicondylitis. Materials and Methods Fifty-two consecutive patients who were diagnosed with medial epicondylitis and underwent an elbow MRI between March 2010 and December 2018 were included in this retrospective study. The patients' demographic information, clinical data, and MRI findings were evaluated. All variables were compared between the conservative treatment and surgical treatment groups. Logistic regression analyses were conducted to identify which factors were associated with surgical treatment. Results Common flexor tear (CFT) tear size showed a statistically significant difference in both the transverse and longitudinal planes (p < 0.001, p = 0.013). The CFT abnormality grade significantly differed in both the transverse and longitudinal planes (p = 0.022, p = 0.003). A significant difference was also found in the medial collateral ligament abnormality (p = 0.025). Logistic regression analyses showed that only the transverse diameter of the CFT tear size (odds ratio: 1.864; 95% confidence interval: 1.264-2.750) was correlated with surgical treatment. Conclusion Of patients diagnosed with medial epicondylitis, patients with a larger transverse CFT tear size tend to undergo surgical treatment ultimately.

Obstructive sleep apnea syndrom(OSAS) is defined by total or partial collapse of the upper airway during sleep. In the presence of specific anatomic features, OSAS is potentially amenable to surgical treatment. Initially, the only treatment available for these patients was a tracheotomy that bypassed the obstruction and resulted in a 100% cure. However, this was not readily accepted by most patients, and surgical methods other than tracheotomy were developed to successfully maintain adequate upper airway patency during sleep by comparing to postoperative polysomnography(AHI,RDI etc). In this paper, I would like to provide an overview of some of the multilevel surgical techniques available for treating OSAS as well as the necessary preoperative considerations.

Purpose : To evaluate the potential advantage for 'sandwich' technique radiotherapy compared to Postoperative radiotherapy in resectable rectal cancer. Materials and Methods : Between January 1989 and Mar 1994, 60 patients with resectable rectal cancer were treated at Inje University Seoul and Sanggye Paik Hospital. Fifty one patients were available for analysis: 20 patients were treated with sandwich technique radiotherapy and 31 patients were treated with Postoperative radiotherapy. In sandwich technique radiotherapy(RT), Patients were treated with preoperative RT 1500 cGy/5fx, followed by immediate curative resection. Patients staged as Astler-Coiler B2, C were considered for postoperative RT with 2500-4500 cGy. in postoperative RT total radiation dose of 4500-6120 cGy, 180 cGy daily at 4-Sweets was delivered. Patients were followed for median period of 25 months. Results : The overall 5-year survival rates for sandwich RT group and postoperative RT group were $60\%$ and $71\%$, respectively(p>0.05). The 5-rear disease free survival rates for each group were $63\%$. There was no difference in local failure rate between two groups($11\%$ versus $7\%$) Incidence of distant metastasis was $11\%$(2/20) in the sandwich technique RT group and $20\%$(6/31) in the postoperative RT group(p>0.05). The frequencies of acute and chronic complications were comparable in both groups. Conclusion : The sandwich technique radiotherapy group shows local recurrence and survival similar to those of Postoperative RT alone group but reduced distant metastasis compared to Postoperative RT group. But long term follow-up and large number of patients is needed to make an any firm conclusion regarding the value of this sandwich technique RT.
