Purpose: Zygomaticomaxillary complex (ZMC) fracture is one of the most common facial injuries after facial trauma. As ZMC composes major facial buttress, it is a key element of the facial contour. So, when we treat these fractures, the operator should have a concern with the symmetry to restore normal appearance and function. But sometimes, unfavorable results may occur. The aim of this study is to analyze the unsatisfied midfacial contour after ZMC fractures reduction retrospectively and to point out the notandum. Methods: 369 patients, treated for fractures of the ZMC were included in the study. After the operation, such as open reduction and internal fixation (ORIF with titanium or absorbable materials), open reduction, and closed reduction, midfacial contour was evaluated with plain films and 3-dimensional computed tomography. And unfavorable asymmetric midfacial contours were correcterd by secondary correction and re-evaluated. Gross photographs were obtained at outpatient clinic. Results: Total of 38 patients had got a facial asymmetry and among of them 24 patients were treated secondary revisional ORIF operations for correction of unfavorable result of after primary reduction. Two of them had received tertiary operations, three patients had got osteotomy more than after one year and six patients had got minor procedures. The etiology of asymmetry were lateral displaced simple fracture of arch (n=2), lateral displaced comminuted fracture of arch (n=6), comminuted arch fracture combined posterior root fracture (n=9), and communited arch and body fracture (n=12), severely contused soft tissue (n=9). After the manipulations outcomes were acceptable. Conclusion: To prevent the asymmetry in ZMC fracture reduction, complete analysis of fracture, choice of appropriate operation technique, consider soft tissue, and secure of zygoma position are important. Especially, we should be more careful about communited fracture of zygomatic body and lateral displacement, root fracture of zygomatic arch. Because they are commom causes that make facial asymmetry. To get optimal result, ensure the definite bony reduction.

Background: There is controversy about the benefit of surgical correction of an atrial septal defect (ASD) in patients over 60 years old. The purpose of this study was to determine whether surgical treatment is beneficial in those 60 years of age or older. Materials and Methods: We reviewed the clinical course of 57 patients (mean age: $63.54{\pm}5.59$ years) diagnosed with an isolated secundum ASD after the age of 60. The 24 patients (group A) who underwent surgical repair were compared with the 33 patients (group B) who were treated non-surgically. The mean follow-up period was $6.8{\pm}4.5$ years. Results: One operative death, 5 late deaths (20.8%) in group A, and 9 deaths (27.3%) in group B occurred in the study period. Symptomatic improvement was noted in 18 patients (75%) of group A after surgery. However 13 patients (39.4%) of group B showed symptomatic improvement during the follow-up period (p=0.012). The incidence of new atrial arrhythmia of the two groups was significantly different (16.7% vs 36.7%, p=0.038). The actuarial 10 year survival rate was 79% in group A and 73% in group B. Conclusion: Although surgical correction of ASD did not increase survival in patients over 60 years old, the surgical outcomes of ASD showed low operative mortality and resulted in symptomatic improvement in the majority of these patients. This study has shown the benefits of surgical closure of ASD even in advanced age in comparison to medical treatment.

Background: Coronary involvement in Takayasu's arteritis is a rare but fatal disease. The aim of this study was to evaluate the early and mid-term results of Takayasu's arteritis patients who underwent coronary artery bypass grafting (CABG). Materials and Methods: Of 2,280 patients who underwent isolated CABG from January 1998 to June 2012, Takayasu's arteritis was identified in 5 patients. There were 3 female patients, and the mean age was $58{\pm}9$ years. Takayasu's arteritis was diagnosed during preoperative evaluation for coronary artery disease in 4 patients, and the initial manifestation was angina pectoris in 4 patients. All of the patients underwent anaortic off-pump CABG (OPCAB) using the in situ left or right internal thoracic arteries (ITA); 3 patients had severe stenosis of the proximal left subclavian artery and the in situ right ITA was used instead. Medical treatment for inflammatory arteritis during the perioperative and follow-up period was performed if indicated. Early, 1-year, and 5-year angiographic results and clinical outcomes were analyzed. Results: There was no surgical mortality, and all of the patients were discharged without complications on postoperative $8{\pm}2$ days. Early postoperative (postoperative $2{\pm}1$ days) angiography demonstrated a graft patency of 100% (12 of 12 distal anastomoses). One-year ($13{\pm}3$ months) angiography was performed in 4 patients, and all of the grafts were patent (100%, 9 of 9 distal anastomoses). Conclusion: By performing anaortic OPCAB in patients with Takayasu's arteritis, we were able to avoid complications associated with manipulating an atherosclerotic and severely calcified ascending aorta. The early and mid-term graft patency of OPCAB in Takayasu's arteritis was maintained when concomitant with medical treatment.

Objectives: The best treatment for the malignant parotid tumor still remains to be defined, and a better knowledge about the tumor features that predict the treatment result is needed. The aim of this study is to evaluate the treatment outcomes and to suggest the optimal treatment modality for the parotid cancer. Materials and Methods: The clinicopathologic characteristics of 113 patients who were treated for parotid cancer from January 1990 to December 2002 were retrospectively analysed. Univalate analyses were performed to establish the prognostic influence of pateint age, gender, tumor size, histologic grade and lymph node metastasis. Results: The mean age was 46.4 years old (15-81 years) and. The male to female ratio was 1 : 1.1. The chief complaint was a palpable mass in 85%, pain was in 12.4% and facial nerve palsy was accompanied with 2.7%. The mean tumor size was 3.5cm in diameter. The most common malignant tumor was mucoepidermoid carcinoma (33.6%), followed by acinic cell carcinoma (15%), adenoid cystic carcinoma (11%), carcinoma expleomorhpic adenoma (11%), basal cell carcinoma (7%). The most common operative procedure was total parotidectomy (47.8%) and various types of cervical lymph node dissection were added in 69.9%. Postoperative radiotherapy was done in 61.1 %. Postoperative complications developed in 54 cases (47.8%), including 46 cases (40.7%) of facial nerve palsy and 9 cases (8%) of Frey's syndrome. Recurrences developed in 21 cases (18.6%) and deaths in 15 (13.3%). Cumulative survival at 5 year was 75.4%. Univariate analysis of clinical factors showed that histologic grade and positive cervical lymph node significantly influenced survival (p<0.05). Conclusion: These results suggests that the radical resection with lymph node dissection and postopertaive XRT would be necessary to improve the survival of the patients with high grade cancer or positive lymphnode metastasis.

완화의학에서 환자의 평가는 치료의 의사결정과 그 결과에 이르기까지 중요한 역할을 한다. 평가도구의 사용 목적은 이를 환자 진료에 반영하여 개개인 환자와 가족들에 대한 돌봄의 질을 높이는 데 있다. 환자의 기능 상태와 통증 및 비 통증 증상을 평가하는 다양한 단일 영역 및 다차원 평가 척도들이 사용 가능하며, 삶의 질을 측정하는 다양한 도구들이 존재한다. 삶의 질이나 증상 측정에서 우월하다고 추천되는 단일 도구는 없는 실정이다. 도구마다 측정하는 시간의 틀이 다르고, 특성이 다르므로 사용 목적과 상황에 따라 적절한 도구를 선택하여야 한다. 여명 예측을 위해서는 예후 지수의 병용이 권고되는 추세이고, 웹을 기반으로 하는 예측 프로그램들도 등장하였다. 예후지수로는 최근 우리나라에서 다기관 연구를 통해 개발한 객관적 예후지수가 임상적인 여명 예측을 포함하지 않으면서 새로운 객관적인 예후 요인을 반영하여, 누구나 쉽게 사용이 가능하다. 완화의학 입문자의 경우 상대적으로 사용이 용이한 도구가 좋다. 따라서 기능의 평가에는 Eastern Cooperative Oncology Group 기능지수를 사용하고, 통증에서는 10점만점의 숫자 통증 등급(Numeric Rating Scale) 도구를 활용하면서 초기 통증 평가로는 간이 통증 조사지를 추천한다. 여러 가지 증상을 한꺼번에 측정하기 위해서는 숫자 등급으로 직접 물어보거나 혹은 M.D. Anderson 증상조사지(the Korean version of MD Anderson Symptom Inventory) 설문지를 사용하기 바란다. 삶의 질을 평가하는데에는 European Organization Research and Treatment Quality of Life Questionnaire Core 15 for Palliative Care, 예후 지수로는 객관적 예후 지수(Objective Prognostic Score)를 사용하기를 권한다. 향후 완화의학에서 평가도구의 발전방향은 국제 공동 연구의 활성화와 디지털 기기를 통한환자 보고의 전산화이고, 머지않은 앞날에 우리나라에도 이러한 경향이 도입될 것이다.

Background and Objectives: Non-small-cell lung cancer (NSCLC) represents approximately 80% of all lung cancers. Unfortunately, at their time of diagnosis, most patients have advanced to unresectable disease with a very poor prognosis. The oriental herbal medicine HangAm-Plus (HAP) has been developed for antitumor purposes, and several previous studies have reported its therapeutic effects. In this study, the efficacy of HAP was evaluated as a third-line treatment for advanced-stage IIIb/IV NSCLC. Methods: The study involved six patients treated at the East- West Cancer Center (EWCC) from April 2010 to October 2011. Inoperable advanced-stage IIIb/IV NSCLC patients received 3,000 or 6,000 mg of HAP on a daily basis over a 12-week period. Computed tomography (CT) scans were obtained from the patients at the time of the initial administration and after 12 weeks of treatment. We observed and analyzed the patients overall survival (OS) and progression-free survival (PFS). Results: Of the six patients, three expired during the study, and the three remaining patients were alive as of October 31, 2011. The OS ranged from 234 to 512 days, with a median survival of 397 days and a one-year survival rate of 66.7%. In the 12-week-interval chest CT assessment, three patients showed stable disease (SD), and the other three showed progressive disease (PD). The PFS of patients ranged from 88 to 512 days, the median PFS being 96 days. Longer OS and PFS were correlated with SD. Although not directly comparable, the OS and the PFS of this study were greater than those of the docetaxel or the best supportive care group in other studies. Conclusion: HAP may prolong the OS and the PFS of inoperable stage IIIb/IV NSCLC patients without significant adverse effects. In the future, more controlled clinical trials with larger samples from multi-centers should be conducted to evaluate the efficacy and the safety of HAP.

Objectives: We investigated the efficacy and safety of miniscalpel acupuncture (MA) for knee osteoarthritis (KOA) in an assessor-blinded randomized controlled pilot trial; this would provide information for a large-scale randomized controlled trial. Methods: Participants (n = 24) were recruited and randomly allocated to the MA group (experimental) or acupuncture group (control). The MA group received treatment once a week for 3 weeks (total of 3 treatments), while the acupuncture group received treatment two times per week for 3 weeks (total of 6 treatments). The primary outcome was pain as assessed by a visual analogue scale (VAS). The secondary outcomes (intensity of current pain, stiffness, and physical function) were assessed using the short-form McGill Pain Questionnaire (SF-MPQ) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Assessments were performed at baseline, 1, 2, and 3 during treatment and at week 5 (2 weeks after the end of treatment). Results: Of the 24 participants, 23 completed the study. Both groups showed significant improvements in VAS, SF-MPQ, and WOMAC. However, there were no significant differences between the MA and acupuncture groups. No serious adverse event occurred and blood test results were within normal limits. Conclusion: Our results suggest that although both MA and acupuncture provide similar effects with regard to pain control in patients with KOA, MA may be more effective in providing pain relief because the same relief was obtained with fewer treatments. A large-scale clinical study is warranted to further clarify these findings.
