To evaluate criteria, indications, and prognosis of the various reconstructive methods on the patients with intraoral soft tissue defect who had been treated at Dept. of Oral and Maxillofacial Surgery, Pusan National University Hospital from 2003 to 2005, we have reviewed the clinical data of the patients and analysed. The results were as follows: 1. Tongue flaps have been mainly applied on anterior portion of palate and maxilla. The survival rate was high percent, but the cooperation of patient was inevitable for the success. 2. Palatal mucosa rotational flaps were available on relative large defect on palate, oroantral fistula site. The side effect was a scaring band from secondary healing on denuded donor palate site. Sometimes the band came to be a hinderance to swallowing, phonation. 3. Forearm free flap was a workhorse flap for everywhere in intraoral defects. We had used the flap on cheek, floor of mouth, tongue without any significant complications. But the application of the flap was required for long operation time, which was disadvantageous to the old, weak patients. 4. Cervical platysmal flap could be easily applicable for buccal cheek, floor of mouth after excision of the cancer lesion. The design of the flap could be made simultaneously on neck dissection, but the danger of cancer remnants on the flap always might be remained. 5. Buccal fat pad pedicled flap must have been a primary flap for repair of oroantral fistula especially on posterior maxilla. The flap survival will be expected if the considerations for above reconstructive methods on site, size, condition of defects primarily could be made.

Objective: The cleft lip and/or palate is the most common congenital anomaly with a high incidence within developing or low-income countries. To overcome the disease burden, humanitarian international missions are essential. In mission operation, patients never underwent any type of preoperative hospital care. Moreover, lots of patients past appropriate time of surgery. Therefore, we investigated primary palatoplasties in mission environments with regard to patients’ age and operation modality. Materials and Methods: The subjects included 106 patients who wanted palatoplasty during cleft missions in Vietnam. Medical records and peri-operative clinical photographs were analyzed retrospectively. Results: Primary palatoplasty was performed at the age of 72.5 months on average. Clinically, incomplete cleft palate was 61.3%. Main surgical technique was V-Y push-back operation with intravelar veloplasty (68%). Additional surgical procedures were pedicled buccal fat pad (33%) and vomer flap (16%). Postoperatively, no motality and any transfusion was not performed. Until 1 month after palatoplasty, fistula rate was 3.8%. Conclusion: For management of untreated cleft palate, which past the appropriate time of palatoplasty, pedicled buccal fat pad could be a reliable additional procedure to decrease postoperative fistula rate.

Introduction: This study examined the effect of the application of low intensity pulsed ultrasound on bone healing after an injection of adipose tissue-derived stem cells (ADSCs) during the implantation of a titanium implant in the tibia of diabetes-induced rats. Materials and Methods: Twelve Sprague-Dawely rats were used. After inducing diabetes, the ADSCs were injected into the hole for the implant. Customized screw type implants, 2.0 mm in diameter and 3.5 ㎜ in length, were implanted in both the tibia of the diabetes-induced rats. After implantation, LIPUS was applied with parameters of 3 MHz, 40 mW/cm 2 , and 10 minutes for 7 days to the left tibiae (experimental group) of the diabetesinduced rats. The right tibiae in each rat were used in the control group. At 1, 2 and 4 week rats were sacrificed, and the bone tissues of both tibia were harvested. The bone tissues of the three rats in each week were used for bone-to-implant contact (BIC) and bone area (BA) analyses and the bone tissues of one rat were used to make sagittal serial sections. Results: In histomorphometric analyses, the BIC in the experimental and control group were respectively, 39.00±18.17% and 42.87±9.27% at 1 week, 43.74±6.83% and 32.27±6.00% at 2 weeks, and 32.62±11.02% and 47.10±9.77% at 4 weeks. The BA in experimental and control group were respectively, 37.28±3.68% and 31.90±2.84% at 1 week, 20.62±2.47% and 15.64±2.69% at 2 weeks, and 11.37±4.54% and 17.69±8.77% at 4 weeks. In immunohistochemistry analyses, Osteoprotegerin expression was strong at 1 and 2 weeks in the experimental group than the control group. Receptor activator of nuclear factor kB ligand expression showed similar staining at each week in the experimental and control group. Conclusion: These results suggest that the application of low intensity pulsed ultrasound after an injection of adipose tissue-derived stem cells during the implantation of titanium implants in the tibia of diabetes-induced rats provided some positive effect on bone regeneration at the early stage after implantation. On the other hand, this method is unable to increase the level of osseointegration and bone regeneration of the implant in an uncontrolled diabetic patient.

Objective: The purpose of this study was to determine whether cyst enucleation would be done after marsupialization of large cystic lesion on the jaws or not, and if so, when it should be done. Patients & Methods: 12 patients with cystic lesion treated by marsupialization only and 10 patients with cystic lesion treated by marsupialization followed by enucleation were examined in this study. Postoperative clinical and radiographic examinations were performed at 1, 4, 7, 10, 13, 16, 19 months on 22 patients. Bone regeneration and reduction rate of the residual cystic cavities and bone density were evaluated with a analysis of digital panoramic radiographs. Also histological evaluation of the healing process was performed on 1 patient. Results: Uneventful healing and spontaneous bony filling of the residual cavities were observed in all cases. Postoperative radiographs showed that the size of the lesions was reduced for a few months, but the reduction rate of the residual cavity was minimized for 13~16 months after marsupialization. The bone density was increased 22.5 % after 19 months. Conclusion: This results suggest that the appropriate timing to perform enucleation would be 13~16 months after marsupialization. The state of healing process could be confirmed by histological examination and radiographic evaluation of bone density. Enucleation after marsupialization could be applied appropriately to reduce the periods of bone healing in large cystic lesion on the jaws.

Splenic abscess is an uncommon entity, occuring in 0.14% to 0.7% of several autopsy series. These early reports asserted that splenic abscesses were due primarily to typhoid fever, ma- laria, bacterial endocarditis, bacteremia and sickle hernoglobinopathies. According to recent report, splenic abscesses are related to infection in contiguous organs, infected traumatic hem- atomas and metastatic bacteremia. Combination therapy of splenectomy with broad spectrum antibiotic is the treatment of choice. We report a splenic abscess developed in the patient with diabetes mellitus after dental extraction and cured by broad spectrum antibiotic and percutaneous drainage.

Today's school management is based on several principles : first, the principle of democratization on which the intellectual faculties of the educational staff can be most efficiently combined ; second, the principle of scientific management, the purpose of which is the simplification of school affairs ; thirdly, the principle of adaptability, whirl can meet the changes in social and educational affairs and the needs of the community. The principle of scientific management is the most important of all these. It is aimed at producing marked educational effects by simplifying and enhancing the efficiency of, the disposition of school personnel, the performance of various species of school affairs, the collection of scattered records and the use of educational facilities. It is of fundamental importance for teachers to dedicate themselves to our national education, which does depend most on their prosecution of researches, pursuit and cultivation of educational principles and methods. And they should also impress upon their mind their decisive role and grave duties in social reform and modernization of the fatherland, from which never-ending prosperity in the 1970s will be derived. The task of an assistant principal is to undertake and handle school affairs and educate pupils and students under the direction of the principal. From this point of view, the writer of this thesis has realized that there has been a general tendency to give teachers so influential directions and to entrust them with, and inform them of, many things so suddenly, that their desire fur education is often discouragingly dampened, school hours as well as those for teaching materials are shortened, for the purpose of examining within a given time urgent official documents. These have been a great obstacle to the sincere performance of their duties. As is mentioned above, a true foundation of school management should be laid on the principles of democratization, scientific management, and adaptability. This is why these hindrances to effective education should be eliminated without delay. Otherwise school education could not be expected to he fruitful, and teachers to be faithful to their own duties.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 4 years(2004-2007), and compared with retrospective study during former 10 years(1992-1996, 1999-2003) in Dept. OMS Pusan National University Hospital. We assessed the cause, type, demographic, etc, and analyzed alterations of facial bone fractures during past 3 periods. The results were as follows. The total number of patients was increased. 429 patients treated for maxillofacial fractures between January 1992 and December 1996, 466 patients treated between January 1992 and December 1996 and 764 patients treated between January 2004 and December 2007. The male-to-female ratio were 4.6:1, 3.9:1, and 4.16:1, respectively. Patient in the age groups of 10-19 years and 20-29 years increased in the latter two periods. Assaults and falls are decreased gradually, but slip down s are increased. Traffic accidents are still major cause of facial trauma. The mandibular fractures showed the highest incidence thorought three periods. Symphysis fractures of mandible was increased and condyle fractures of mandible was drecreased in the third period.
