Maxillary defect may be induced by trauma, inflammation, cyst, tumor and surgical procedure. In case of limited wall defect, free bone graft has been preferred. But it has some problems such as postoperative bone resorption and soft tissue inclusion to recipient site. And we can not use free bone in the case who has inflammation in the donor site. So we used the micro-titanium mesh as reconstructive material for the maxillary wall defect. We had operated 8 patients who were diagnosed as maxillary partial defects from June 1997 to September 1998 in the Chin-Hae military hospital. They were 1 case of antral wall defect, 1 case of palatal wall defect, 5 cases of infra-orbital wall defects and 1 case of oroantral fistula case. As a result, the micro-titanium mesh has shown the morphological stability and biocompatibility and it could be used in case who has infection. And mesh structure could prevent soft tissue ingrowth to bony defect area. Thus it can be used to the case of maxillary partial defect successfully.

Ventricular septal defect was the most common congenital Heart disease admitted to the Severance Hospital from December, 1963 to June 30. 1977. A total of 1,811 cardiac patients received cardiac catheterization in the CardiacCenter of Yonsei University Medical College. Out of the 1,811 cardiac patients, 791 cases had congenital heart disease and of these 172 cases had ventricular septal defect. This amounted to 21.7% of all those with congenital heart disease. Seventy cases of ventricular septal defect operated on in the chest surgery department are presented. Of these 70 cases of ventricular septal defect, 54 cases were male and 16 cases were female. Their ages ranged from 4/12 months to 32 years. The ratio of systolic pressure of the main pulmonary to systemic artery [Pp/Ps] for 29 of the 59 isolated ventricular septal defects was below 45 percent. Pp/Ps ratio for 19 of the 59 isolated ventricular septal defects was 75 percent. The patients were mostly below fifteen years of age. Out of 64 cases, there were 36 cases of type II defects, 20 cases of type I, 4 cases of type III , 2 cases of type IV, one case of both type II and one case of left ventricular right atrial communication. The anomalies associated with ventricular septal defect were 13 in all; 4 cases of aortic insufficiency, 3 cases of ruptured aneurysm of the sortie sinus of valsalva, 2 cases of ruptured aneurysm of the sortie sinus of valsalva with aortic insufficiency, 2 cases of patent ductus arteriosus, one case of ruptured aneurysm of the aortic sinus of valsalva with atrial septal defect [secundum type] and one case of atrial septal defect [secundum type]. Overall mortality was 8.6 percent. The mortality in pulmonary artery banding was 37.5 percent. The causes of mortality were in one case congestive heart failure, in one case asphyxia and in one case respiratory insufficiency. Tile mortality in ventricular septal defect associated with pulmonary hypertension was 7.1 percent. The cause of mortality was in one case low cardiac output syndrome. There was no mortality in the ventricular septal defects without pulmonary hypertension and mortality in the ventricular septal defect. In ventricular septal defect associated with combined anomalies, the causes mortality were in one case respiratory insufficiency and in one case congestive heart failure.

A case of bronchogenic cyst associated with a partial pericardial defect is reported. Bronchogenic cysts are not so rare in incidence, but they are more rare when associated with a pericardial defect, the first case being reported by Rusby and Sellors in 1945. Recently, we experienced such a rare case of a bronchogenic cyst with a partial pericardial defect. The patient is a 39-year-old female and she was found to have a left anterior mediastinal mass during routine chest X-ray. During the operation, we detected partial pericardial defect after removal of the mediastinal mass. The pericardial defect was repaired with a Gore-Tex Membrane. The pathological examination of the mass showed a bronchogenic cyst. The patient had an uneventful hospital course.

The development of aortic insufficiency radically alters the physical findings which are generally associated with ventricular septal defect that was not hemodynamically significant, and the combination of the two lesions produces a typical clinical picture, that may be serious and life-threatening when it is left untreated. Therefore, the selection of patients, type and timing of surgical treatment is considered to be important. Among 114 cases of ventricular septal defect treated surgically utilizing cardiopulmonary bypass in the Department of Thoracic Surgery, Seoul National University Hospital, 7 cases were associated with aortic insufficiency. 1. Five cases were male, and 2 cases were female. Ages were from 4 years to 24 years, and mean age was 11.9 years. 2. In all cases, ventricular septal defect was closed with Teflon patch. In a case, a aortic valvuloplasty and in another, a aortic valve replacement with Hancock valve 23 mm., 5 months after the closure of ventricular septal defect were done. 3. Four cases were type I ventricular septal defect by Kirklin`s classification, 3 cases were type II ventricular septal defect, and diameters of ventricular septal defect were from 3.5 cm. to 0.7 cm. A PDA. was combined to a type I ventricular septal defect. 4. In 5 cases, herniation of the aortic cusp through the ventricular septal defect and in a case, annulus dilatation on the aortic valve was noted. 5. Two cases with type I ventricular septal defect and severe pulmonary hypertension expired. A re-opened case with type II ventricular septal defect expired. 6. Four cases were alive, and all of them show decrease of pulse pressure and aortic insufficiency.

Seven patients had undergone repair of endocardial cushion defect from Jan. 1977 to Dec. 1984 at National Medical Center. Most patients had no associated anomalies except one who had PFO, and mortality case was absent. Five patients had partial ECD and two had complete ECD [Rastelli type A]. In P-ECD patients, the atrial septal defect was closed with patch in all cases and mitral cleft was approximated with 2-3 direct stitches. In two cases of C-ECD, atrial and ventricular septal defect was closed with single patch in one case and atrial septal defect was closed with patch but ventricular septal defect was closed with patch but ventricular septal defect was closed it direct suture in the other case. Atrioventricular cleft was approximated with 2-3 direct sutures. Postop. transient A-V block was noted in 2 cases but returned to regular sinus rhythm after 2 to 6 months.

Since 2000s in Korea, apartment building tended to become goods or assets rather than houses. Therefore, conflicts between supplier and consumer were aggravated, and the defect dispute has been increased rapidly. This dispute enlarges to defect lawsuit and it is social and economical matter. The landscape work in apartment building is main work for a resident that appearance and convenient facility which lawn, tree, fountain, chair, playground, and etc. A number of defects surround landscape work are important issue in defect lawsuit, but, a related research is a minority, and a regulation is incomplete. Therefore, this study is basic study for standard of landscape defect type. As case study on defect lawsuit, draw a landscape defect type in apartment building.

There is urgent for defect consulting work to standardize the investigated method, repaired and reinforced method, and estimated cost about defect in increasing a defect lawsuit of apartment building. For the purpose of developing the standard process of defect consulting work, the review that a used process in law and institution should take precedence. There is not prepared the national standard for defect consulting but is dependent on an experience and a practice of consultants. This study analyzes defect consulting case, defines main steps for developing the standard process, and draws phased work factors. As systemizing this, it is expected to apply to basic structure for developing the standard process of defect consulting work for the next.

The combined anomaly of pulmonary stenosis with atrial or ventricular septal defects is usually associated with decreased pulmonary blood flow and right to left shunt, and result in generalized cyanosis. Non-cyanotic pulmonary stenosis patients have generally been considered to have isolated pulmonary stenosis with intact septa. We are going to report a case of pulmonary stenosis with septal defects who have no frank cyanosis at rest because of the predominant intracardiac shunt from left to right. Recently, we managed surgically a case of pulmonary valvular stenosis combined with secundum type atrial septal defect, type II ventricular septal defect, and patent ductus arteriosus. The clinical manifestations of this patient were exertional dyspnea, frequent upper respiratory infection, chest discomfortness and lethargy since late childhood and these had been progressively aggravated. Pulmonary valvular stenosis, atrial septal defect and ventricular septal defect were closed through simply right atriotomy and patent ductus arteriosus through pulmonary arteriotomy. Immediate postoperative course was uneventful and one year follow up is excellent.

Left ventricular-Right atrial canal is a rare congenital heart disease. The vast majority of the cases reported in the literature are clinically diagnosed as atrial septal defect or ventricular septal defect. The method of choice in establishing the diagnosis of left ventricular-right atrlal canal is selective left ventriculography. Recently we experienced one case of left ventricular-right atrial canal which was diagnosed as ventricular septal defect preoperatively. The type of defect was tricuspid perforation of infravalvular type, and repaired with direct suture. Postoperative course was uneventful and discharged without complication.
