  • Segmental resection or wedge resection of the lung and direct cutting across of bronchi frequently results in postoperative airleaks or bronchopleural fistula in some cases. Many methods have been devised to handle air leak problems by oversuturing the raw edges, the application of pleural onlay flaps, the use of cautery or tissue adhesives, but these still has not solved the problem of air leaking from raw surfaces of the lung with only partial successful we have tried the use of histoacryl to closure the raw surface of the resected lung and compared it’s results with of the closure with chromic catgut sutures in cats from May 1989 to Jan. 1990 at the department of the thoracic and cardiovascular surgery, Yonsei University, College of Medicine. Ninety lobe of the lungs were used in this study and forty nine of which have been divided segmentally and closed with histoacryl on the raw surfaces. Forty one of which have been divided segmentally and closed with sutures using chromic catgut for control. There were air leakages in twelve cases among 49 cases with applying histoacryl and airleak were in two cases among 12 cases with reapply histoacryl, But there were air leak in two cases among 41 cases with sutures using chromic catgut and airleak were in one case among with resutures using chromic catgut.

  • In coronary artery bypass grafting, a diffusely diseased left anterior descending coronary artery (LAD) is an obstacle to achieving complete revascularization, consequently leading to the possibility of a poor prognosis. Long segmental reconstruction with or without endarterectomy is a revascularization method for treating diffusely diseased coronary arteries. Herein, we report a successful case of long segmental reconstruction of a diffusely diseased LAD using a left internal thoracic artery onlay patch after endarterectomy.

  • There are various modalities in the treatment of facial asymmetry, but in severe case with TMD by actively growing deformed condyle, the treatment choice is removing the condyle growth center and TMD symptom such as click or muscular discomfort. In our one case, the patient was complain of facial asymmetry. There are severe deformed condyle head with bird-head fashion and enlarged mandibular ramus and body vertically about 18 mm, overgrowthed Rt. mandible body horizontally about 20 mm. She had intermittent Lt. TMJ clicking and muscular discomfort. The author diagnosed it as Lt. hemimandibular hyper-plasia & R, hemimandibular elongation, a combination form with TMD. the condyle was in active growing state in scintigraphic analysis. So we extirpated the deformed condyle by intrasoral sagittal split ramus osteotomy and reshaped the condyle and mandibular distal fragment extraorally. The distal fragment was readapted in glenoid fossa and fixated. In Rt. mandibular body area, autogenous onlay bone graft on the inferior border of mandible was performed to correct the asymmetry. The clicking and facial asymmetry was corrected and we report this results with other literature findings.

  • The spontaneous rupture of the esophagus is an uncommon disease, but without early diagnosis and treatment, the mortality rate is high. This report is on the two cases treated at the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyu-ngpook National University. The first patient, after heavy drinking, had vomiting followed by chest pain, dyspnea and subcutaneous emphysema. After diagnosis using an esophagogram, an operation was perfomed. About a 4cm rupture was found at the lower left part of the esophagus and was primarily sutured with the intercostal muscle. The patient was weaned from the ventilator after 40 hours. The second patient had symptoms the same as the first case. Six days after the app-earence of the symptoms, the patient was treated by the Thais onlay gastric patch method. The leakage happened after the surgery and he received a conservative treatment. After discharge no abnormalities, such as leakage and stricture, were found on the eso-phagogram The two patients now live a normal life.

  • 대동맥판막질환에 동반된 허혈성 심질환의 원인은 대부분 전신적인 동맥경화의 진행에 따른 것이며, 심한 석회화가 초래된 대동맥판협착증 환자에서 대동맥판막의 일부가 떨어져 나와서 관상동맥 색전증 및 협착을 유발시킨 예는 매우 드물다. 저자들은 흉부압박감을 주소로 내원한 73세 여자 환자에서 심초음파검사와 관상동맥조영술을 시행하여 중증 대동맥판협착증과 우관상동맥의 색전증을 진단하고 대동맥판치환술과 우관상동맥의 색전제거술 및 관상동맥성형술을 시행하였던 예를 치험하였다. 수술 후 우관상동맥 색전의 원인 물질이 대동맥판막으로부터 떨어져 나온 석회성 판막조직으로 판단되었기에 이와 관련된 문헌고찰과 함께 보고하는 바이다.

  • A 23.5 kg179, 8 months olds non-spaycd female Rottweiler dog was submitted to the veterinary teaching animal hospitals Chonbuk: national university, for chronic bitten trauma on right foreleg with pain, lameness, and pronation. The patient fought with a neighboring dog about five months ago and had mild anorexia, depression, bolt normal walking at that time. CBC and blood chemical examination were in normal range. Physical examination resulted in the right foreleg with edema and interval rotation of carpal joint. Radiograph of the right carpus showed varus and subluxation. We finally diagnosed the patient as the growth deformity of distal radius and ulna caused by medial premature closure of distal radial physis. Osteotomy was performed fur reforming of the varus of the distal radius and ulna with 6-hole straight plate and six 3.5 mm screws. Panarthrodcsis of carpus was preformed for correcting subluxation using 6-hole T-shaped plate and four 3.5 mm screws with cortical onlay autograft and strengthened by two 3.5 mm screws and tension wire band in lateral aspect of the carpus. Follow-up radiographs after 16 weeds of the surgery showed complete coaptation of osteotomy sire of the radius and uIna. After 6 months of the procedurc, talc plate, screws and the wire were removed except 7-shaped plate and four screws fur arthrodesis. The patient was seen in normal forelimb and could walk and run without lameness after 7 months of the procedure.

  • The purpose of this study was to investigate the influence of balancing interference on the mandibular movement and masticatory muscle activity. 5 subjects(male. average age of 24.3) without dysfuction in masticatory system were selected. The balancing interference was provided by construction of cast metal crown and onlay on the upper and lower first molars. Clinical examination, changes displacement and velocity, and muscle activity were recorded and analyzed by means of BioPak system(Bioresearch Inc., Milwaukee Wisconsin. USA). The results were as follows ; 1. In clinical examination, various symptoms were reported by all subjects after application of interference. Almost symptoms were subsided after elimination of interference. 2. In the border movements in frontal plane, lateral border movement toward non-interference side was changed according to the interference after application of interference. Immediately after removal of interference, border movements' pattern was recovered as same as before experiment. 3. During gum chewing on the non-interference side, horizontal movement was decreased immediately after application of interference(p<0.05). 1 week after application of interference, horizontal movement was more decreased in 3 subjects and showed a chopping type masticatory stroke. But in 2subjects, horizontal movement was increased to avoid interference. 4. In EMG of the mandibular rest position, no significant changes were showed in the experiment period(p>0.05). 5. During gum chewing on the interference side, the activity of opposite temporal muscle was increased immediately after application of interference(p<0.05). 1 week after application of interference. The activity of ipsilateral temporal muscle and left and right masseter muscles was increased (p<0.05). 1 week after elimination of interference, increased muscle activity was recovered about the same level as before experiment. 6. During gum chewing on the non-interference side, 1 week after application of interference, the activity of ipsilateral temporal muscle was increased (p<0.05). 1 week after elimination of interference. increased muscle activity was returned about the same level as before experiment.

  • Background: This report describes the authors' experience of "melting" septal cartilage after placement of a septal extension graft in a nasopharyngeal cancer patient that had been previously undergone radiation therapy, and provides a review of the literature. Methods: Electronic medical records were used to obtain details of the patient's clinical history. Results: A 32-year-old woman, who had previously undergone radiotherapy for nasopharyngeal cancer, visited our department to for rhinoplasty. Rhinoplasty was performed using a septal extension graft to raise the nasal tip (first operation). Five days after surgery, it was found that the septal extension graft was melting without any signs of infection, that is, the graft had softened, lost elasticity, thinned, and partially disappeared without any sign of infection at 5 days, and thus, the nasal tip was reconstructed with conchal cartilage (second operation). Five months after surgery, it was found that almost all septal cartilage had disappeared without any sign of infection, and thus, the entire nasal septum was reconstructed using 2-mm costal cartilage and an onlay graft was used for tip augmentation (third operation). Conclusions: After cartilage has been exposed to radiotherapy, its patency should be viewed with suspicion. Further studies are needed for determine the mechanism responsible for cartilage damage after radiotherapy.

  • Purpose: Anterior ridge defect after tooth extraction results in unfavorable appearance. Ridge augmentation procedures should be preceded by careful surgical-prosthetic treatment planning, and various techniques can be used in anterior ridge augmentation. Materials and Methods: Three patients showed deformed ridges after tooth extraction. Three different techniques ; onlay-interpositional connective tissue graft; bovine hydroxyapatite graft with free connective tissue graft; bovine hydroxyapatite graft with resorbable collagen membrane following free connective tissue graft; were used for anterior ridge augmentation. Result: Soft tissue graft can be used in small amount of ridge defect, hard tissue graft combined with soft tissue graft can be used in large amount of ridge defect. After ridge augmentation, about three months of healing period, augmented tissue was stabilized. The final restoration was initiated after this healing period, and the tissue form was maintained stable. Conclusion: Careful diagnosis and surgical-prosthetic treatment planning with joint consultation prior to surgery should be performed in order to attain an optimal esthetic results.
