Mucoepidermoid carcinomas, first reported by Volkman(1895), form 6% to 9% of all salivary tumors. Two thirds affecting the parotid gland and the remaining third, the minor glands. As we could know from its name, mucoepidermoid carcinomas originate from ductal epithelium including squamous, mucous-secreting, and undifferentiated intermediate cells. Histologically, it is classified as well-differentiated (low grade), moderately-differentiated(intermediate grade), and poorly-differentiated (high grade) types and the treatment method and prognosis are influenced from its histological grade. We have experienced two cases of mucoepidermoid carcinoma treated surgically with good results and now would like to report these with review of literatures.

Eagle's syndrome is the term given to symtomatic elogation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Since ossification of stylohyoid ligament at cadeva was fist described by De Manchetics in 1652 and Weinlecher described clinical symptom which produced by elongated styloid process and osteotomy of styloid process in 1872, Clinical symptom which include sensation of a foreign body on the pharynx, dysphagai, dysphonia, referred pain, and mouth opening disturbance was termed by Eagle as Eagle's syndrome. then, case reports of Eagle's syndrome are presented. in these cases, the patient's chief complaints included periauricular radiating pain, mouth opening disturbance, foreign body sensation, dysphagia, tenderness on the neck. Through vairous X-ray examination and palpation of tonsillar fossa, elongted styloid process were confirmed. Under the general anesthesia there were successfully removed out via transoral approach technique, described by Eagle. after resented styloid process, they were freed from the symptoms without further complication. Therefor we reported these cases treated by surgical resection of styloid process with good results.

Ossifying fibroma is a relatively slow growing tumor, and likely to have presented for some years before its clinical diognosis. The usually well circumscribed nature of ossifying fibroma in jaws lends itself to relative ease of excision and hence the favorable therapeutic results. On occasion, however, particulary in juvenile patient, if maxilla the tumor assumes an aggressive behavior. In that case, because the tumor grows invasively, resection with a margin of healthy tissue is indicated. The case presented is 34 - year old female. The patient had noticed a gradual swelling of the right side of the face approximately 2 months in duration correlation with a intermittent pain on the right maxillary molar area. Palpation disclosed firm swelling on the right anterior and lateral walls of the maxillary sinus extended to the maxillary tuberosity area. The radiographic examination revealed soft tissue mass with multiple dense round calcifications with destruction of anterior and posterolateral wall of the right maxillary sinus and right alveolar process, and hard palate. The mass totally obliterated maxillary sinus and extended to the pterygopalatine fossa. The histologic diagnosis from the biopsied specimen revealed ossifying fibroma. The tumor mass was resected by subtotal maxillectomy procedure due to a recent rapid infiltrative growth. In 5 months of postoperative follow - up period, the patient has favorable prognosis.

저자들은 오랜 기간 관해 상태를 유지하던 중 재발한 Chrug- Strauss 증후군 환자에서 시클로포스파마이드 및 경구용 스테로이드 치료 중 발생한 폐농양 1예를 경험하였다. 본 증례 는 장기간의 관해 후에도 Churg-Strauss 증후군이 재발할 수 있고 치료 중 감염이 발생하였을 때 폐포자충폐렴이나 거대 세포 바이러스 감염과 같은 기회감염 이외에 세균 감염도 발생할 수 있음을 보여주는 증례이기에 문헌고찰과 함께 보 고하는 바이다. Churg-Strauss syndrome (CSS) is a rare disease characterized by asthma, peripheral eosinophilia and vasculitis. A quarter of CSS patients with clinical remission have experienced a relapse. We report here a case of lung abscess in a patient with relapsed CSS. A 46-year-old man who achieved clinical remission of CSS was confirmed for relapse by the presence of peripheral eosinophillia, pulmonary lesions and perivascular infiltrate of eosinophils in colon pathology. After administration of systemic glucocorticoid and one cycle of cyclophosphamide pulse therapy, he complained of dyspnea, sputum and chest pain. There were necrotic masses containing internal air-fluid levels in the right upper and the left lower lobes of the lung on chest radiography. Percutaneous needle aspiration culture specimens revealed the presence of K. pneumoniae. The patient was successfully treated with a 5-week course of antibiotics. (Korean J Med 2014;86:106-109)

Presently, Erbium:YAG laser, which is known as laser for osteotomy, is considered to have good resection effects and to bring about minimum thermal damage. Since studies on this has never been done within the country and left as a field still unexplored, I expect to use this study as experimental data on future use of laser on hard tissue. In this report, both surgical bur(diameter 0.5mm carbide roun bur) and Erbium:YAG laser(100mJ/pulse, 10pulse/sec) was used each on the femur of white mouse and after the same amount of osteotomy, the effect of bone healing on the light microscope was observed and comparative study was made histology. The results are as follows : 1. In the first group (1st day, 3rd day), the osteotomic bone portion of the experimental group was irregular with bone resorption and showed more blood cell infiltration, compared with the control group. 2. At 1 week, bone matrix and immature bone was formed in the peripheral and center of the resection area in the control group. But inthe experimental group, more bone formation was initiated in the peripheral than in the center and showed more infiltration of blood cells and inflammatory cells. 3. At 2 week, bone matrix became mature to have similar density with compact bone and showed new formed vessels in the control group. But in the experimental group, bone formation with decreased density was initiated and new formed vessels together with mature bones was observed. 4. At 3 week, mature bone with equal density and regular trabecular pattern was observed in the control group. But in the experimental group, the continuity between the new bone and old bone was rather loose with decreased maturity, but on the other hand, had even bone formation pattern. 5. At 4 week, both the control and experimental group showed perfect bone healing features. From the results above, I can observe that in osteotomy with Erbium:YAG laser bone healing is rather delayed in each step but if, effective percentage of resection could obtained it would be valuable to substitute mechnical bur or saw and bring about much progress and development in the area of oral and maxillofacial surgery. For this, more studies on bone resection and biomechanical strength of bone tissue after bone healing should be done on various animals.

Maxillofacial infection often place the oral and maxillofacial surgeon in situations where timely decisions have to be made. These decisions can be lifesaving. Odontogenic infection are frequently encountered in the practice of oral and maxillofacial surgery. These infections often repond to surgical and antimicrobial management. Otheriwise odontogenic infections have the potential to spread via the fasical spaces in the head and neck region. They can compromise vital structures in this region or involve distant structures. The classic signs of maxillofacial infections include pain, swelling, fever, dysphagia, and dehydration. The goals of management should be to correct these conditions. We have undertaken clinical studies on infections in the oral and maxillofacial regions (facial space) by analyzing hospitalized patients in the Dept. of Oral and Maxillofacial Surgery, Kyung Hee University Hospital past 5 years from 1991. to 1995. And bacterial cultures and antibiotics sensitivity test were performed and the comparative analysis of the antibiotics was done. The results were as follows: 1. The most frequent cause of oral and maxillofacial infection was odontogenic 68% and in 23% patients with signs and symptom aggrevated after teeth extraction. 2. The most common fascial spaces involved was buccal space 36.1%, followed by submandibular space 12.3% and 3 cases were Ludwig s angina. 3. Antibiotics were administrated in all cases and surgical incision and drainage was performed in 88.6%. 4. The most causative organisms isolated from the pus cultures were streptococci group 51.1%
