좌측 상악 구치부와 협부의 무통성 종창을 주소로 내원한 16세 여자의 좌측 상악동에서 다량의 석회화 침착과 미맹출지를 포항한 COC 1예를 구내 접근법을 통해 외과적으로 제거하였다. 적출물은 $50{\times}40{\times}35mm$의 크기였고 낭종벽으로 잘 피낭되어 있었다. 조직학적으로는 잘 발달된 상피 내벽과 ghost cell이 나타나 COC의 소견을 보였으며 석회화물은 complex odontoma의 양상을 보여 COC의 type IB로 분류되었다. 술후 1년이 지난 현재 안모의 개선을 나타내고 있으며 재발의 증상 없이 양호한 경과를 보여주고 있다. A case of calcifying odontogenic cyst associated with an unerupted tooth which appeared in the left maxillary sinus of a 16-year-old woman, was reported. Clinical examination revealed painless swelling on the left maxillary posterior region and the cheek. Radiographically, this lesion showed a monolocular radiolucent shadow with calcified materials and unerupted maxillary second premolar. Histological examination revealed cystic structure with presence of the ghost cells, calcified tissue and unerupted tooth. This lesion was classified as Type IB of COC according to classification of the Praetorius. After surgical removal of the cyst, the wound healed uneventfully and the lesion is now free of symptoms.

Pleomorphic adenoma is a circumscribed tumor characterized microscopically by its pleomorphic or mixed apprearance, and its clearly recognizable epithelial tissue intermingled with areas of mucoid, mixed, or chondroid appearance. Pleomorphic adenoma, the most common tumor of the salivary glands, is now generally accepted as epithelial and benign adenoma, The palate is the most common location for minor salivary gland tumor. The neoplasm has been found in all age groups, the majority being in the fifth decade with an age ranged from 30 to 50. Minor salivary gland lesions appear a decade later, ranging in age from 40 to 60. We experienced three cases of pleomorphic adenoma occuring in the palate. They were treated with complete local exicision and reconstructed with pedicled temporal fascial, flap, pedicled buccal fat pad, and palatal islands flap each.

Tetanus is a rare disease which is caused by the exotoxin produced by Clostridium tetani. The exotoxin affects the central nervous system and its main site of action is the interneuronal synapses of the inhibitory pathways where it induce a blockade of spinal inhibition resulting in muscular rigidity. Tetanus may occur when the microorganisms are introduced not ony through wouds that provide anaerobic conditions but also without obvious portal of entry. The incubation period of tetanus varies from three days to four weeks(usually about seven days). Generally, patients with tetanus show early trismus due to the masseteric spasm with varying degree of hypertonicity of the muscles in the neck, back, abdomen and limbs. The spasms of the facial muscles result in risus sardonicus and spasm of spinal musculature causes opisthotonus. Spasms can by precipitated by all forms of stimuli such as noise, light and touch. Recently we encountered three cases of tetanus in 35-, 40-, and 54-year-old male. Their initial presentations were trismus with or without dyspnea. Subsequently, they developed muscular spasm which led to the diagnosis of tetanus, This paper reports these relatively unusual cases with the general description about tetanus and the management of the condition.

The purpose of this study was to investigate the stress distribution and the biomechanism of mandibular condylar fracture, because the condyle is one of the sites predisposed to fracture. Clinical and experimental studies on the fracture mechanism have so far been undertaken by a number of our precedessor. It's possible that fracture pattern of condylar process was influencend by the morphological characteristies of the condylar head. In this analysis, loading was applied to four directions in the model of the mandibular body, and three directions in the model of the condylar head. The results obtained were as follows: 1. Lange stress arised on the condylar head in simulated model with the loading on the mandible symphysis rather than mandible angle, and maximal principal stress arised on the articular eminence. 2. It were supposed that fracture arised on the condylar neck with tendency of the maximal stress on the condylar neck with the all 4 types when the 45 degree and horizontal loading was directed into condylar head. Especially, the tendency was remarkable on the horizontal load of convex type. The stress was remarkable on the pole area in the vertical loading. 3. With the same loading these were supposed that comminuted fracture on the condylar head arised on convex and round type. Especially, the tendency was remarkable in the convex type. 4. The size of displacement was observed in the direction of horizontal, 45 degree and vertical to the descending parameter. The direction of displacement was observed on the upper area of the mandibular head to the internally to the horizontal and 45 degree loading with the all cases, and externally to the vertical loading with the flat and angled cases. Especially, the internal displacement tendency was observed on the condylar head to the all derectional loading with the convex type. Above results suggest that condylar fracture is supposed with the loading on the mandible. Especially, frequency of the fracture is remarkable on the condylar neck area.

Malignant fibrous histiocytoma rarely occurs in the jaws. Although the histogenesis of this tumor remains controversal, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. It is common for metastatic foci to appear in lung and regional lymph node. There are variable treatments such as radiotherapy, surgical excision or combination, therapy of surgical excision, chemotherapy and radiotherapy. With the review of literatures, the authors report the clinical study of two cases of malignant fibrous histiocytoma of the jaw.
