The surgical treatment of craniofacial disorders, using metallic internal osteofixation system has inspired an evolution with advanced operative technique and fixation devices over past two decades. As any other surgical procedures, this procedure also associates problems such as infection, palpability, loosening, and restrict craniofacial skeleton growth, which lead to undue secondary operations for removal. These problems are improved by using bioabsorbable osteofixation system. We compared the patient's subjective symptoms using bioaborbable system versus metallic osteofixation system in zygomatic bone fracture. we should take the individual steps (postoperative 2 weeks, and 1 year) in treating fractured zygoma. From August, 2001 to August, 2003, we used bioabsorbable osteofixation system in 28 patients in zygomatic fracture ($Biosorb^{TM}FX^{(R)}$) and compared 23 patients who were treated with metallic osteofixation system. There was no significant difference in the both groups in subjective symptoms and postoperative result.

Between 1977 and 1987, 8 patients underwent excision of cardiac myxomas at the Hanyang University Hospital. All had a left atrial myxoma. There were 4 female and 4 male patients ranging from 15 to 62 years of age. Preoperative findings consist of symptoms and signs of congestive heart failure except one. Diagnosis was confirmed by echocardiography[8 cases] and angiography[2 cases], preoperatively. A biatrial operative approach was utilized in all but 2, who were small sized. Complete excision of the tumor with a cuff of normal tissue[1 was atrial wall and 7 were atrial septum] was performed. all heart chambers were carefully explored for presence of multicentric myxomas or tumor debris. There were no operative deaths or intraoperative embolization. Follow-up has been 1/3 to 10 years. There has been 1 late death, due to recurrence and 1 patient had reoperation for mitral regurgitation due to dilatation of the annulus by a huge tumor mass. Surgical excision of the myxoma can be performed with low morbidity, and it provides excellent and sustained symptomatic relief. The recurrence rate is low, but long-term follow-up and serial echocardiography are advisable.

Castleman`s disease is a rare disease entity of unknown etiology, with the characteristics of large, well marginated benign lymph node hyperplastic mass. This disease occurs predominantly in the mediastinum but also occurred in other areas of the body usually where lymph nodes are normally found. They have been divided into two histologic types: the hyaline vascular lesion which comprises over 90% of the cases; the plasma cell lesions, which was characterized by large follicle with plasma cell and systemic manifestation, such as fever, anemia elevated ESR, hypergammaglobulinemia, hypoalbuminemia. This disease have behaved in a benign fashion and complete surgical excision is the choice of treatment. We experienced a case of Castleman`s disease which was treated by surgical resection through the thoracotomy, and has good postoperative and follow up result. We report a case of the Castleman`s disease with its review.

Esophageal atresia with tracheoesophageal fistula may occur as separate, but usually occur in combination. First described by Thomas Gibson in 1696, esophageal atresia was not successfully treated until 1939 when the first two survivors of staged correction were described by Ladd and Leven. In 1941, Haight and Towsley performed the first successful one-stage primary repair. We report three cases of esophageal atresia with tracheoesophageal fistula of which were treated with one-stage surgical repair method. The operation was performed tra-nspleurally through right 4th intercostal space. The fistula in the trachea was closed with interrupted 5-O prolene sutures and esophagoesophageal anastomosis was performed with 3-O prolene single layer sutures in all cases. All patients tolerated the operative procedures and recovered uneventfully. On follow-up study, anastomotic stricture was developed in one patients, so esophageal dilatation was performed for it with the Griintzig balloon catheter and the result was satisfactory. The other patients were well-being without any complication.

A coronary artery fistula was surgically ligated in a 38-year-old woman via a left anterior mini-thoracotomy without the use of cardiopulmonary bypass. In selected cases, this surgical approach can provide an excellent surgical exposure for coronary artery fistula ligation. It also offers an excellent cosmetic result and shorter hospital stay.

Myasthenia gravis is an autoimmune disease in which the thymus gland is thought to play a central role in the pathogenesis. Thymectomy is now standard therapy, and improvements in surgical techniques, anesthesia, and respiratory care and the use of plasmapheresis have markedly reduced the operative morbidity. We experienced 7 myasthenia gravis with maximal thymectomy from November 1989. As compared with the results of previous classic transsternal thymectomy group the 25 patients who were operated from June 1979 to December 1991[Group B], excellent surgical result was obtained in maximal thymectomy group[Group A]. During follow-up period that ranged from a month to 10.7 years[mean 2 years], the remission rate for the entire group was 15.6 percent and an additional 71.9 percent had improvement[87.5 percent benefited]. In Group A, the remission rate was 42.9 percent with 100 percent of the patients benefiting from operations. But in Group B, 8 percent had remission and a total of 80 percent benefited. In both Groups, there was no operative mortality but there was one case`s mortality in Group B during follow-up period.

The otitis externa frequently occurs in dog. The cause is mostlyan increase of bacterias (for example Staphylococcus spp. Streptococcus spp. and Psudomonas spp.) and/or yeast fungi (especially malassizia pachydermatis) and/or infestation with parasites (otodecits cynotis) which growth is promoted by a change of the microclimate in the external auditory meatus. The worse therapeutic results of medicine is explained by an intolerance and resistence of microorganisms which was often observed. In this study of dog with otitis externa developed a generalised pyoderma. This, in fact, could be a causative factor in the development of otitis externa and its recurrence. Concluded, the surgical treatment is the best method for eliminating chronic otitis externa.

Background ; To evaluate the efficacy of Fibrin glue to decrease recurrence in video-assisted thoracoscopic surgery(VATS) for a treatment of spontaneous penumothorax. Material and Method : All medical records of 17 patients who underwent a thoracoscopic wedge resections of bullae with stapling device with Fibrin glue in our institute between May 1998 and December 1999 were reviewed. variables analyzed include affected sites primary indication of VATS. duration from admission to discharge duration of postoperative stay duration of chest tube drainage recurrence and complication. There were 16 men and 1 woman. Result : There was no evidence of hemodynamic instability or arterial blood gas abnormalities encountered during the procedure. Mean age at the time of the VATS was 26.9 years (range 15 to 61 years) The mean duration from admission to discharge was 7.8 days and mean postoperative stay was 5.1days mean chest tube indwelling period was 4..0 days. There was no recurrence of pneumothorx. Conclusion : Thoracoscopic wedge resections with introduction of fibrin glue are safe and effective and requires only a short hospital stay. We believe that this thoracoscopic technique will further simplify the surgical treatment of pneumothorax.

Background: Neuroblastoma is the third most common malignancy of chidhood, and is the most common mediastinal mass in children under the age of 2 years. However, the results of surgical treatment have been seldomly reported in Korea. Therefore, we analyzed the results of surgical treatment in children with neuroblastoma and its influencing factors. Material and Method: We studied the clinical characteristics and prognosis of 12 children, 11 makes and 1 female, whose primary thoracic neurobalstomas or ganglioneuroblastomas were diagnosed and operated between 1977 and 1997. Men age at presentation was 29.9 months. Result: Respiratory symptoms were the modes of performed in 9 patients. Complete excision, partial excision, and biopsy only were performed in 9, 2, and 1 patients respectively. Ten patients of thoractic neuroblastomas survived (83.3%) during follow-up period. Conclusion: The postoperatve 5-year survival of thoracic neuroblastoma was 76.4% and the prognosis was related to the stage of neuroblastoma. We suggest that complete resection should be considered as preferential method in the treatment of thoracic neuroblastoma in children, especially with early stage.

Permanent canine are very important teeth in point of function as well as esthetic. Therefore impaction of canines is a frequently encountered clinical problems. The incidence of impaction ranges between 1-3%. The cause of canine impaction can be result of ectopic position of tooth germ, defect of dental follicle, early loss or delayed exfoliation primary canine, space problem, supernumarary teeth, cyst, odontoma, Impaction frequently involves further complication such as root resorption of adjacent teeth, cyst formation and migration of the neighboring teeth. Various treatment modalities include extraction of primary canine, surgical opening and orthodontic traction, autotransplantation, surgical extraction of impacted canine.
