An arteriovenous malformation (AVM) may be defined as a condition in which arteries communicate with veins through channels other than the normal capillary networks. The common unifying clinical element is severe bleeding which can result from this type of lesion. Most sophisticated diagnostic studies include selective arteriogram and ultrasound flowmeter. The treatment for such mass is predicated upon a total elimination of all diseased tissue. AVM in location such as the spinal cord and cerebral vessel are particular poorly treated with surgical excision. Therefore, the technique of intraarterial embolization was first used for these lesions. Certain extensive lesions that are considered inoperable may be treated with embolization alone. The author had managed a patient, 15 year old male, with arteriovenous malformation of the left face involving mandible. Through femoral artery, embolization with polyvinyl alcohol (PVA) was performed. At 1st embolization (1983-12-30), PVA were embolized into his left facial, lingual and internal maxillary arteries. In March 1984, he had repeated gingival bleeding. An angiographic study of the carotid arteries demonstrated the AVM fed by left external carotid artery and right facial artery. At that time, PVA were embolized into his left facial, lingual arteries and right facial arteries. Sixty days postoperatively, no signs of AVM had recurred.

study was undertaken to investigate the effects of combined surgical orthodontic treatment on the mandibular movements and functional rehabilitation. Recordings of functional and border movements with sirognathograph unit(Bio-Pack. Bioresearch Inc. Wisconsin. U.S.A.) were obtained in 26dentofacial deformity patents, who were treated in the Department. Of Oral and Maxillofacial Surgery, Collge Dentistry, Kyung Hee University from April 1991 to July 1993, before surgery, after removal of intermaxillary fixation, 6 and 12 months from the surgery. To groupe the corelation of orthognathic surgery and mandibular movements, statistical analysis was performed by the operation methods (sagittal split ramus osteotomy and vertical ramus osteotomy) and the duration of intermaxillary fixation(IMF). The results were as follows. 1. The mandibular open-closing patterns in dentofacial deformity patients showed a even distribution of undeviated, cross over and noncross over form before and after mandibular setback surgery, but in the open-closing maximal effective width and lateral deviation, there was more noticeable tendency toward normalization and improvement, in vertical ramus osteotomy than sagittal split osteotomy group. 2. After mandibular setback surgery, the mandibular open-closing velocity patterns were significantly improved that, there was decrease in irregularity (from 38% to 15%), reduction of premature contact, and increase in maximal velocity(from 247.1mm/sec to 294.2mm/sec). 3. After mandibular setback surgery, the amount of maximal protrusion significantly increased from 6.8mm before to 8.1 mm 12 months after surgery and there showed better recovery rate in the sagittal split ramus osteotomy than in the vertical ramus osteotomy group. 4. The amount of hinge and translatory movements after mandibular setback surgery showed relatively more decrease and more slow recovery in the vertical ramus osteotomy group. 5. The amount and angle of lateral movement after mandibular setback surgery were decreased immediately after IMF removal but recovered soon and significantly increased 12 months after surgery. There showed a good recovery tendency in the sagittal split ramus osteotomy and short IMF period group. This general tendency can be interpreted as the result of normalization in dentofacial skeletal morphology through surgery with positive consequence in the function of the muscle and temporomandibular joint. In the future, additional data, such as patient s temporomandibular disorder symptom, radiographic assesment of mandibular condyle, and the relationship between the condyle and disc, should be needed for definite analysis of mandibular movements after orthognathic surgery with systemic measurement of sirognathographic registration.

We had presented a case of benign cementoblastoma of left mandibular body area of 16 year old female patient. The benign cementoblastoma, as defined by the W.H.O., is a neoplasm characterized by the formation of sheets of cementum-like tissue which may contain a very large number of reversal lines and be unmineralized at the periphery of the mass or in the more active growth area. The patient was admitted to Department of Oral & Maxillofacial Surgery, Kyung Hee University Medical Center with chief complaint of painless swelling on the left mandibular body area. We were certained of benign cementoblastoma through clinical and radiographic feature, and then performed surgical enucleation of tumor including removal of involved teeth. After 9 months follow up check, we noticed the bony replacement of operation site and no recurrence and so patient had an temporary removable partial denture.

The present study was designed to consider the changes of the temporomandibular joint after mandibular oblique osteotomy of the cats. In order to carry out this experiment, 17 cats weighing about 3.0kg were selected. One cat was preserved for control and 16 animals were divided into 8 groups, 1 day, 3 days, 5 days, 1 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks. Under the general anesthesia with pentobarbital sodium, the experimental animals were performed oblique osteotomy on both mandibular ramus and wire fixation at mandibular border. The experimental animals were sacrificed consecutively on the 1st day, 3rd day, the 5th day, the 1st week, the 2nd week, the 4th week, the 6th week, the 8th week after surgery and the mandible were dissected out carefully to produce tissue specimen. The specimens were fixed with 10% formalin solution for 24 hours and rinsed with phosphate buffer solution. It was decalcified with 5% nitric acid for 15 days. Thereafter the specimens were dehydrated in alcohol series and embedded paraffin as usual manner. The embedded specimen were sectioned in 4-6μm, stained with hematoxylin-eosin and immunohistochemical stain, and observed through light microscope and polarizing microscope. The results were as follows: 1. The remarkable changes were appeard in the articular surfaces of temporal bone, the articular disc, the retrodiscal tissue, the fibrocartilage layer of condyle, the hypertrophic layer of condyle, the bone marrow of condyle at the 1st week after treatment. 2. Extreme hyperplasia of the fibrocartilage layer and thickening of prechondroblastic-chondroblastic layer in the 2 weeks after treatment. 3. In the 6th and 8th week post experimental animals, a pattern of response observed dense, regular arrangement in the fibrocartilage layer of the articular fossa and the mandibular condyle and in the articular disc. 4. The TGF gradually appeared in condylar bone marrow at 5 days after and increased at 2 weeks after and decreased at 8 weeks after.

This is to report a case of cystic hygroma occured in the left submandibular area of 12 year-old male patient. The patient was admitted to Department of Oral and Maxillofacial Surgery, Kyung-Hee University Medical Center with the chief complaints of left submandibular swelling. Cystic hygroma are a benign neoplasm of developmental origin that are characterized by large endothelial-lined space and found predominantly in the region of the head and neck, commonly in the posterior trianglar of the neck, but in this case, the lesion was found in the anterior triangle. In this case, cystic hygroma is not invade the floor of the mouth and base of the tongue and surgically excised specimen is ovoid, lobulated and 6㎝ × 2㎝ × 4㎝ in size and that is filled with watery, straw-colored fluid. The histological appearance is that of multiple dilated and collapsed lymphatic channels lined by a single layer of flattened endothelium. Focal lymphocytic infiltration as well as small sprouts or buds of lymphangiomatous tissue may extend into adjacent tissue. It is best treated by surgical excision soon after recognition in order to prevent extensive local growth and expansion. This case is of interest because their diagnosis was made when the patient was 12 year-old male patient.

Myxomas are rare tumor that probably arise from the mesenchymal portion of the dental papilla, dental follicle, or periodontal membrane. This is to report a case of myxoma occurred in the left maxillary alveolar portion, maxillary sinus and pterygomaxillary fossa. The patient, 28 years-old female, was admitted to Dept, of Oral & Maxillofacial Surgery, Kyung Hee University Medical Center with the chief complaint of painless mass on the upper left molar area. In this case, the roentgenographic findings revealed sun-ray appearance, root resorption, displacement of involved tooth and destruction of lateroposterior wall of maxillary sinus. The histopathological findings revealed a soft tissue covered by hyperplastic stratified squamous epithelium with prominent rate ridge and no cellular atypia, The upper portion of underlying connective tissue is composed of fibrous collagenous tissue with numerous proliferating fibroblasts and infiltration of large numbers of chronic inflammatory cells and deep portion is made up of loosely arranged, spindle shaped and stellate cells with long fibrillar process. Conservative local curettage is the preferred treatment. Removal of the maxilla or mandible should be avoided if at all possible. Removal should be done only when pathologic fracture or extension of the tumor into the vital anatomical structures is inevitable. In this case, we performed curettagement of the tumor via intraoral approach.
