Twenty six patients were operated a total correction of tetralogy of Fallot between Jan., 1984 and July, 1985 at the Dept. of thoracic and cardiovascular surgery, Chonnam University Medical School, and a comparison between the survived group [n = 18] and the dead group [n = B was performed to detect factors influencing laboratory data, cineangiographic findings, operative findings and methods, and pump time. Following results were obtained, 1. There was no significant difference between two groups in the preoperative P.O2 and hematocrit level. 2. The size of the interventricular defect was not related to the operative mortality. 3. There was a significant difference in mortality rate between combined type of stenosis of pulmonary artery, valve and infundibulum and other types of right ventricular outflow tract stenosis. 4. There was a significant difference in mortality rate between the transannular patch reconstruction and other types of operative procedure. 5. There was no significant difference between two groups in total bypass time and aortic time. 6. There was no significant difference between two groups in left ventricular end diastolic volume and right ventricular end diastolic volume. 7. The operative mortality was related to the ratio of the diameter of the pulmonary valve annulus or each pulmonary artery to the ascending or descending aorta in cineangiographic findings, but there was no statistical significance of which probably is due to the lack of the total number of patients.

A total of 20 patients underwent bullectomy in the spontaneous pneumothorax between October 1993 and August 1994. The patients were divided into two groups: Control group; the patients who received with mid-axillary approach[n=10 , Experimental group; the patients who received with video-assisted thoracic surgery [n = 10 . The results were as follows; 1. The total sex distribution was male predominence [M :F=6:1 . Mean age of control group was 31.6$\pm$ 10.1 age and experimental group was 24.3$\pm$ 5.5 age. 2. The operative times were 117.0 $\pm$ 32.6min in control group and 102.5$\pm$ 38.4min in experimental group [not significant . 3. The indwelling period of postoperative chest tube and hospital stay were 4.5$\pm$ 2.6 days and 8.3 $\pm$ 1.8 days in control group, $1.5\pm$ 0.5 days and 3.1 $\pm$ 0.3 days in experimental group[p=0.0018, < 0.0001 . 4. In control group, injection times of pain-killer were 1.7$\pm$ 0.7 times/day at operative day and 0.4$\pm$ 0.6times/day at postoperative 1 day. In experimental group, there were 0.3$\pm$ 0.7times/day at operative day and 0.1 $\pm$ 0.3times/day at postoperative 1 day[p=O.O002 at operative day, not significant at postoperative 1 day .

Background: Class II malocclusion patients with hyperdivergent facial types are characterized by short mandibular body lengths and anterior open bite. Accordingly, the treatment for hyperdivergent skeletal class II malocclusion is a lengthening of the mandibular body length and a counterclockwise rotation of the mandible. To prevent post-operative relapse, botulinum toxin-A (BTX-A) injection can be a retention modality. Case presentation: A class II open-bite patient received BTX-A injection to the anterior belly of her digastric muscle for the prevention of post-operative relapse. The relapse was evaluated via a clinical examination and a lateral cephalometric radiograph after the completion of post-surgical orthodontic treatment. The patient showed stable occlusion without any signs of relapse at 15 months post-operatively. Conclusion: In this case presentation, a single injection into the anterior belly of the digastric muscle was sufficient for the prevention of post-operative open bite.

Although nonoperative reduction plays a major role in the management of uncomplicated intussusception in the pediatric age group, surgical treatment is still a necessary alternative when nonoperative reduction is unsuccessful. The author analyzed the clinical features of 68 patients requiring operation in order to identify factors which might influence the type of operative management. A nine-year experience at Ewha Womans University Hospital was reviewed, and the findings compared to previous reports. Barium was used for the initial reduction attempt in 33 cases, saline in 35. Manual reduction by milking at operation achieved success in 41 cases(60.3%). Fifteen cases(22.1%) required resection of bowel, and 12 patients(17.6%) were found to have spontaneous and complete reduction of the intussusception at operation. Two cases had pathologic leading points. There were no perforations due to nonoperative reduction. There were no significant differences in demographic data, clinical findings, laboratory data, and anatomic type of intussusception between barium and saline reduction groups. However, a significant number of cases with spontaneous reduction were in saline reduction group(p<0.05). There was a slight chance of spontaneous reduction in infants under 6 month of age(p<0.001). Age under 6 month. body temperature over $38^{\circ}C$, symptom over 24 hours, and ileo-colic and ileo-ileo-colic intussusception contributed significantly to the necessity for bowel resection(p<0.05-0.001). The author believes that the age, body temperature, duration of illness, and anatomic type of intussusception strongly influence operative management.

The aim of this report was to present a rare case of a tracheotomy site recurrence after operation and post-operative radiotherapy in head and neck squamous cell carcinoma patient. Tracheotomy site recurrence other than subglottic cancer is very rare in head and neck cancer patient. The granulation tissue around tracheotomy was a fertile "soil" for tumor cell implantation. Midline mucosal sparing block which was used to decreased acute toxicity during post-operative radiotherapy could be facilitating the tumor cell implantation. The head and neck surgeon should try every effort to reduce contamination of cancer cells during operation and consider the entire operative field should be included in post-operative radiation portals.

Surgery remains the mainstay in the management of carcinoma of the rectum. However, local recurrence and systemic metastasis remain the challenge. It appears that post operative radiotherapy has a very definite role in the reduction of local recurrence. Minty two patients of carcinoma of the rectum after curative surgery received post operative radiotherapy $5,000rad/5\~6weeks$ to whole pelvis at the Department of Therapeutic Radiology, Seoul National University Hospital between March 1979 and December 1982. Fifty three percent of patients show modified Astler-Coiler stage C2. Actuarial disease free survival rate of rectal cancer was : stage B1, 2 $75\%$, stage C1 $81\%$ stage C2 $39\%$, and stage C3 $20\%$, Twelve percent shows local recurrence and distant metastasis occurred in $28\%$. Prognostic significance of nodal metastasis is also analysed. Incidence of small bewel obstruction, requiring surgery, is $8\%$, occurring between 5th month to 12 th month after operation. It is suggested that post operative radiotherapy of the rectal cancer following curative surgery has a significant role in the reduction of local recurrence.

The present study was conducted to assess error rates with diagnosis using intra-operative frozen sections, and to indicate ways to increase overall performance. Over a period of two years, 227 cases were biopsied intra-operatively. Errors were observed in 14 cases. Four of these were sampling errors, one by a pathologist and three by surgeons. In seven cases incorrect interpretations were made. Epithelial dysplasia was observed on definitive histology in two cases which was not reported intra-operatively. One case was of ectopic thyroid. In cases of oral cancer where sentinel lymph nodes were sampled, immunohistochemistry for cytokeratin was performed to facilitate identification of micrometastasis. Only single case displayed tumor deposits which was not evident morphologically. Resection margins were reported in seventy eight cases. Some 18% (14/50) benefited from revision of margins; overall sensitivity of intra-operative frozen sections for marginal status was 71.4%, with a specificity of 90.3%. Overall sensitivity was 75% and specificity was 97.5%. Careful observation, pathologist experience and knowledge of limitations help in improving the overall diagnostic outcome.

There are few reported cases of post-operative spondylitis caused by $Mycobacterium$ $Intracellulare$. A 75-year-old female presented to our hospital with low back pain and paraparesis after a fall. The radiologic examination revealed compression fractures of L1, L3 and L4 and an epidural hematoma compressing the spinal cord. The dark-red epidural hematoma was urgently evacuated. Four weeks post-operatively, neurologic deficits recurred with fever. On magnetic resonance image, an epidural abscess and osteomyelitis were detected in the previous operative site. Five weeks post-operatively, revision was performed with multiple biopsies. The specimen were positive for acid-fast bacilli and traditional anti-tuberculous medications were started. Because the Polymerase Chain Reaction for non-tuberculous mycobacterium (NTM) was positive, the anti-tuberculous medications were changed to anti-NTM drugs. However, the neurologic deficits did not improve and persistent elevation of erythrocyte sedimentation rate and C-reactive protein were noted. Eight weeks after the revision, $Mycobacterium$ $Intracellulare$ was detected in the specimen cultures. Despite supportive care with medication, the patient died due to multiple organ failure.

This study was conducted to evaluate and compare the apical leakage in the following retrograde techniques; apicoectomys, retrograde filling with zinc oxide eugenol cement, non-zinc and zinc amalgam, and cold-burnished gutta-percha method. One hundred twenty five upper anterior and lower premolar teeth were divided into five above mentioned groups and each tooth was individually prepared for its particular group. The specimens were incubated at $37^{\circ}C$ for 14 days and then were infiltrated by 2% methylene blue for 24 hours. The apical leakage was evaluated by measuring the degree of dye penetration between the filling material and the canal wall. The results were as follows: 1. The cold-burnished gutta-percha group showed the least amount of apical leakage and the apicoectomy group showed the greastest amount of apical leakage. 2. Statistics showed that there were significant differences among the groups (P<0.05), however there was no difference between the zinc oxide eugenol cement retrograde filling group and the non-zinc amalgam retrograde filling group (P>0.05).

Injuries to the major vessels in the thoracic inlet require early recognition and expedient operative approach. Delayed diagnosis difficulties encountered in the operative exposure of the region are the major factors limiting successful management. This report is a review of 13 patients with vascular injuries to the neck base who were managed at Busan National University Hospital from March 1975 to September 1978 about 3 years and 6 months. The important clinical problems are delineated with emphasis on the technical aspects of operative management. 1] Among 13 cases, 8 cases were male 5 cases were female. 2] Of 28 vascular injuries, subclavian axillary vascular injuries were 22 [78%]. Stab wound was the cause in 70% of these patients. 3] Without extension 7 cases[53.8%] were managed successfully with supraclavicular, and axillary incision. Posterolateral thoracotomy one of extending 4 cases, 2 cases were used right musculoskeletal flap for management of proximal part of the subclavian artery and innominate vessel, 2 cases were used left supraclavicular incision with anterolateral thoracotomy for management of left proximal subclavian artery. One Expired. 4] Repair of vascular injury was accomplished by lateral suture of debridement and end-to end anastomosis in 17[74%]. Autogenous vein was used one for interposition graft. Ligation was required 2 arterial, 6 venous injuries. Of 8 cases which were pulseless preoperatively, 5 cases were able to palpable distal pulse. 5] Post operative complications occurred 50%. Complication of vasular repair was rare. The majority was neurologic deficit (33.3%).
