The therapeutic methods and follow - up prognosis of subcondylar fractures in adults have always been sources of controversy. To improve the therepeutic results in subcondylar fractures with displacement, and especially, the bicondylar ones, the auther employ the surgical reduction using of sagittal split and oblique subcondylar osteotomy. This report is illustrated by six clinical cases.

Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.

The purpose of this study was to observe the tissue response to the orthodontic force applied immediately after buccal horizontal subapical osteotomy of maxilla. Five mongrel cats weighing about 2.5 Kg were used for this experiment. The left upper canine and premolar of each cat served as a experimental side and the right ones as a control side. On the experimental side, a 100gm orthodontic force was applied between the upper canine and premolar immediately after the osteotomy. On the control side, the same orthodontic force was applied without the osteotomy. After 7days, the experimental animals were sacrificed. The results were as follows: 1. In the pressure zones of the experimental group, significant increase of osteoclasts and direct resolution along the alveolar bone surface was observed as compared with those of the control group. 2. In the pressure 2ones of the experimental group, a less extensive hyalinized zone was observed than those of the control group. 3. In the pressure zones of both group, no root resorption was found. 4. Tn the tension zones of the experimental group, new bone deposition increased along the alveolar bone surface as compared with those of the control group. In conclusion, the results suggest the possibility that early orthodontic treatment after orthognathic surgery may have some benefits if the stability of the repositioned segment at surgery is secured.

This is a report of cases that post-operative orocutaneous through & through open wounds are healed & closed by wound contraction if soft tissue drainage was well established, which seldom is interfered with by local or systemic abnormalities. Authors also found that the localization & seguestration of infected mandible are far better performed by natural mechanisms than by cutting across involved bone.

A tracheostomy is performed to relieve an upper airway obstruction, to facilitate bronchial toilet, to decrease dead space, to assist ventilation and as an elective procedure in head and neck surgery. Many complications are associated with tracheostomy, both in the actual performance of the operation and in the postoperative management. Recently the authors report one case ; a two years old children got a severe burn on face and neck and received tracheostomy and have carried tracheostomy cannula for 10 years, at last the cannula was worn out and the 12 years old boy came to the hospital.

Background: Post-pneumonectomy empyema(PPE) is an uncommon but a serious complication. The management remains as challenge for general thoracic surgeons. Material and Method: During the period of January 1990 to December 1996, we evaluated the results of 20 patients with post-pneumonectomy empyema. Result: Sex ratio were 15 male and 5 female patients with mean age of 41.5${\pm}$21.5 yrs. The occurrence ratio of left to right side was 8:12. The most common disease for prior pneumonectomy was pulmonary tuberculosis. The duration between pneumonectomy and PPE was variable in 1 month to 6yrs. Fever was the most frequent symptom and S. aureus was the most frequent pathogen. In 13 cases, there were combined with BPF. Four patients underwent trans-sternal closure, and Clagett procedure was performed. There was one recurrence that later underwent muscle plombage and omentopexy later. Nine patients underwent omentopexy, muscle plombage and thoracoplasty. There were 7 cases that were not combined with BPF. All 7 patients underwent thoracoplasty, and two of them were combined with muscle plombage. Mean follow-up duration is 40${\pm}$32.3 months. There were no late deaths nor recurrences of PPE. Conclusion: We conclude that early diagnosis and proper drainage in PPE patients are important in its initial stage of management, and also management is completely achieved in thoracoplasty with muscle plombage or omentopexy.

Purpose : To describe long-term clinical results and serial changes in the postoperative range of motion(ROM) after arthroscopic treatment for a limitation of motion(LOM) of the elbow. Materials and Methods : The subjects who visited chosun university hospital from December, 1996 to January 2000 were twenty-one patients ranging from 37 to 54 years of age, and the average age was 43.2 years. The chief complaints were painful limitation of motion of the elbow and average ROM showed that flexion contracture were 17 degrees and further flexion were 87 degrees. Results : The total ROM was $70^{\circ}$ preoperatively. 2 months after postoperatively the mean flexion contracute improved from $17^{\circ}\;to\;3^{\circ}$ with further flexion from $87^{\circ}\;to\;122^{\circ}$ degrees. One year after postoperatively the mean flexion contracture were $5^{\circ}$ and further flexion were $113^{\circ}$. All patients reported a decresement in pain level as well as improvement in motion. There was no complication in this series. Conclusion : Arthroscopic surgery appear to be satisfactory management modality for degenerative elbow contractures.

The incidence of decannulation difficulty included tracheal stenosis has markedly increased in recent years because of translaryngeal intubation and tracheostomy although advancing antibiotics and new treatment for these problems. Treatment has always been difficult but in mild cases, a new soft, flexible tracheal T-tube that designed to maintain an adequate tracheal airway as well as to provide support in the reconstructed trachea and in severe cases, transverse resection with subsquent end to end anastomosis has been used in recent years. Authors experienced 2 cases of tracheal stenosis and decannulation difficulty which developed after tracheostomy that was performed due to automobile accident and fall down respectively and using a silicone tracheal T-tube for 3 months good results were obtained. So authors reported with brief review of literatures.

The management of neonate with long gap atresia without a fistula(type A) is complex and controversial. Various esophageal reconstruction include use of native esophagus or replacement with colon, stomach and small bowel. A severe premature male, at 28 weeks gestation weighing 1.2kg, was born with type A esophageal atresia in Chonnam University Hospital. Initial treatment consisted of gastrostomy under the local anesthesia and suctioning of proximal pouch, and than underwent delayed esophageal end to end anastomosis. A minimal leakage and mediastinitis ocurred postoperatively, but was treated by adequate drainage and negative suction from the leakage site through the gastrostomy. The patient was discharged in good general condition and normal weight of 5.4kg after 4 months after the surgery.

Lung volume reduction surgery(LVRS) has recently been advocated as an alternative or a bridge to lung transplantation for patients with evere dibbling emphysema. This procedure is a palliative treatment performed to alleviate the dyspnea of patients with emphysema and improve performance in the activities of daily living. The rationale of lung volume reduction for generalized emphysema is that the removing of the diseased and functionless lung may improve the function of remaining, less diseased lung. The factors critical to the success of LVRS are careful patient selection, accurate localization of target areas, meticulous anesthetic and operative technique, and intensive postoperative support. We have experienced a case of severe emphysema in a 59-year-old male patient. After selection process and pulmonary rehabilitation, the patient was treated with video-assisted thoracoscopic LVRS and the post-operative course was uneventful.
