We have observed 360 cases of spontaneous pneumothorax from Jan. 1971 to Dec. 1981 at the department of Thoracic and Card iovascular Surgery, Yonsei University College of Medicine. The patients age ranged from 2 days to 95 year-old. The associated pulmonary lesions were shown pulmonary tuberculosis in 158 cases[43.9%], bullae in 35, pulmonary emphysema In 32, pneumothorax in 10, paragonimiasis In 7 and unknown underlying pathology in 109 patients. 70 [51.1 %] out of 1 37 cases who received conservative medical treatment Including thoracentesis were cured completely, but the 67 cases [48.9 %] of remaining uncured patients were treated by surgical procedures. The 290 patients who received surgical management were recovered without recurrent pneumothorax. The surgical procedures were closed thoracotomy drainage or explothoracotomy. The choice of treatment should be based on the extent of pneumothorax or the presence of underlying pulmonary disease. Tube thoracotomywas the most effective procedure in achieving the expansion of collapsed lung. On the other hand, open thoracotomy could be a good approach to recurrent pneumothorax, persistent air leakage, incomplete expansion of the lung and bilateral pneumothorax. The minithoracotomy Is the best procedure to recurrent pneumothorax.

Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.

Background: Functional closure of the orbicularis oris muscle and esthetic reconstruction of nasolabial components are impossible in patients with severely deformed premaxilla. Here, we review a surgical strategy for patients with unremedied premaxilla retrospectively. Results: Vomerine ostectomy and premaxillary setback with nasolabial repair were performed in 12 patients with bilateral cleft lip and palate. The mean age of patients was 21.7 months. The extent of ostectomy varied between 3 and 11 mm. There were no serious complications from defective perfusion to the premaxilla or the philtral flap. The follow-up period ranged from 2 to 25 months. Proper positioning of the premaxilla and satisfactory nasolabial esthetics were achieved in all patients. Conclusions: We performed nasolabial repair after premaxillary setback without jeopardizing the premaxillary segment or the philtral flap. Our surgical strategy could be recommended in poor socio-economic circumstances due to the cost effectiveness of limiting the number of surgeries.

Initial successful treatment of postpneumonectomy empyema depends to a large extent on adequate dependent drainage of the empyema sac and the use of antibiotics. But definite control of the infected space remains a disturbing and controversial area in the field of thoracic surgery. A 55-year-old man had a right pneumonectomy for tuberculosis with the development of postoperative thoracic empyema and in October 1973. Postoperatively, an empyema developed and the condition was managed with closed drainage and an open window thoracostomy. He was transferred to our institution in October 1988, and underwent thoracoplasty for the obliteration of the empyema space, resulting in a remaining space. The remaining space after thoracoplasty was obliterated by myoplasty using a rotation flap of splitted pectoralis major muscle three months later. He was discharged with uneventful course 12 days after operation, and continues to do well 3 months following operation. Our experience shows that thoracoplasty and myoplasty offer an effective alternative method of management of post-pneumonectomy empyema.

We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

Most thyroid cancers are well-differentiated cancers and have a very good prognosis. About 10% of thyroid cancer, however, invades the surrounding tissues, causing local recurrence and distant metastasis, and eventually affecting survival rate. In locally advanced thyroid cancers, the invasion of trachea, larynx and esophagus, can be occurred by primary tumor and may also result in lymph nodes metastasis. Surgical resection is still mainstay for the treatment of locally advanced thyroid cancer. The main purpose of the surgical resection is to eliminate the cancer completely, therefore, it can cause many complications such as dysfunction of the larynx, trachea and esophagus. It can have a serious effect on the quality of life, therefore there is still controversy on the extent of the surgery. The authors compare and analyze the opinions which were already discussed in the literatures published so far. These will help to select the surgical method.

The authors describe the experience with the interactive image-guided Zeiss SMN system, which has been applied to 20 patients with various intracranial lesions during one year. Preoperative radiologic evaluation was CT scan in 6 cases, MRI in 14 cases. In all except one case, average fiducial registration errors were less than 2mm. There was no statistical difference in registration error between CT and MR image. This system considered to be relatively stable with respect to soft and hardware. Also it was useful for the designing of the scalp incision and bone flap and assessing the extent of resection in tumors, especially in gliomas. Moreover, it was helpful to evaluate complex surgical anatomy in skull base surgery.

From Jan. 1983 to Dec. 1985, seven cases of pectus excavatum, six were male and one female, were underwent an operation at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. The ages of patients ranged from 6 to 27 years. They all had symptoms of feeling inferiority about chest deformity. The concavity on the funnel chest varied in its extent, and the severity, which was measured by water volume filled into it, varied from 59.5cc/m2 to 129.9cc/m2. All but one patients were approached through a bilateral transverse submammary incision and one approached through a vertical midline incision. Successful surgical correction required resection of all deformed costal cartilages with transverse anterior osteotomy and internal fixation using retrosternal metal bar. No serious complication have followed the use of this technique, but minor complications such as serous accumulation, pneumothorax and strut migration have been experienced. All patients were satisfactory about the surgical results.

Esophageal fistulas may occur in an advanced stage or as a potentially life-threatening complication of treatment. They can be divided into esophageal-respiratory and esophageal-aorta fistulas. The diagnosis is confirmed with fluoroscopy using dilute barium oral contrast, followed by thin-section computed tomography, which defines the precise location and extent of the fistula. Flexible esophagoscopy and bronchoscopy are required for confirmation and anatomic assessment of the suspected fistula and provide additional information for treatment planning. Contamination is traditionally controlled by surgical exclusion, along with a jejunal feeding tube. Currently, fully covered self-expanding metal stents are the primary treatment option.

Purpose: To evaluate the factors which affect the level of the amputation for treatment of DM foot excluding arterial occlusion. Materials and Methods: We selected 30 patients (10 of major amputations, 20 of minor amputations) who were amputated from May, 1999 to April, 2001 because of DM foot. Major amputation is BK amputation, and minor amputation is amputation below ankle joint. Gender, age, size of the wound, extent of the necrosis, infectious organism, medical com orbidity, duration of DM and blood glucose level, duration of DM foot and treatment history were investigated. Results: In major amputations, male to female ratio was 9:1, average of the age was 63.8, the average of sizes of the wound was 16cm2, duration of DM was 15.0 years, duration of DM foot was 10.6 weeks, and 80% of patients had necrosis and the organisms were S. aureus, E. faecium, Streptococcus, P. vulgaris, average of the blood glucose levels was 301 and 40% of them had been treated for DM foot. In minor amputations, male to female ration was 9:1, average of the age was 56.6, the average of sizes of the wound was 4.8cm2, duration of DM was 11.2 years, duration of DM foot was 5.7 weeks, and 40% of patients had necrosis and the organisms were S. aureus, Streptococcus, M. morganini, E. faecium, average of the blood glucose levels was 257 and 20% of them had been treated for DM foot. Conclusion: In DM foot patients, extents of the necrosis, duration of DM, duration of DM foot, the infectious organism were significant factors to decide extent of the amputation level.
