This is a retrospective study on condylar fracture of mandible. The stucy based on a series of 112 patients who had treated for the fractures of mandibular condyle on Kyunghee Dental Hospital from January, 1989 to August 1997. We studied the age and sex distributions, causes of fractures, location of fractures and so on. The results as follow : 1. The ratio of male : female was 4:1, and the highest frequency of condylar fractures was registered among patients aged to 21 to 30 years. 2. The most common cause of condylar fractures was fall-down(47.7%), followed in incidence by direct-blow(27.9%) and traffic accidents(20.7%). 3. Subcondylar fracture had highest incidence(50%), and followed by condyle head(27.4%) and condylar neck(22.6%). 4. 9.7% of condylar fractures had occurred bilaterally and in cases of bilateral condylar fractures, condylar head fractures(58.33%) was hightest incidence. 5. Mandibular symphysis was most commonly involved in condylar fracture(63.4%), and 27.7% of condylar fractures had not any other mandibular fractures.

Mucormycosis is an acute opportunistic infection caused by a saprophytic fungus found in soil, decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. Throughout the history of mucormycosis, from the first case in humans reported in 1885 by Paltauf, through publication by Gregory et al of the first observation of rhino-orbital cerebral mucormycosis in 1943, to the report by Harris in 1955 of the first known survivor, little has changed in the diagnosis and outcome of this disease. Without treatment, the patient may die after an interval ranging from a few days to a few weeks. Regulation of diabetes mellitus and a decrease in the dose of immunosuppressive drugs facilitate the treatment of Mucormycosis. Extensive debridement of craniofacial lesions appears to be very important. intravenous amphotericin B is clearly of value. This is a case report of a patient with mucormycosis in maxilla. He was an uncontrolled DM patient, and for the treatment of intravenous amphotericin B and sequestrectomy were applied.

Carcinomas derived from ameloblastomas have been designated by a variety of terms, including malignant ameloblastoma, ameloblastic carcinoma, metastatic ameloblastoma, and primary intra-alveolar epidermoid carcinoma. The term of ameloblastic carcinoma is differentiated from the term of malignant amelblastoma and is defined as an ameloblastoma in which there is histologic evidence of malignancy in the primary tumor or the recurrent tumor(or metastasis), regardless of whether it has metastasized. The well-documented and adequately followed cases are currently lacking and this report described an instance of ameloblastic carcinoma with good result after treatment and review of literature.

Basal cell nevus syndrome is inherited as an autosomal dominant trait with variable expressivity. This syndrome comprises a number of abnormalities such as multiple nevoid basal cell carcinomas of the skin, skeletal abnormalities as bifid rib and fusion of vertebrae, central nervous system abnormalities as mental retardation, eye abnormalities, and multiple odontogenic kerato cysts. In 1960, Gorlin and Goltz first described the features of this disease as constituting a true syndrome; since then, it has been realized that it is much more complex and encompassing than initially thought. This patient has many symtoms of basal cell nevus syndrome. we has known multiple jaw cysts through panorama and facial computed tomography. He has hyperchromatism on basal cell through skin biopsy. In ophthalmologic consult, he has blindness on right. On his past medical history, amputation was done on his toes for polyductalism. - So we report with literature reviews

The osteochondroma, also known as osteocartilaginous exostosis, is one of the most common benign tumors of the axial skeleton. These tumours rarely affect the facial skeleton and a true osteochondroma of the mandibular condyle is a very uncommon entity. The tumors are usually slow growing, and symptoms develop over a long time. The most common presentation of the condylar osteochondroma consists of a changing occlusion, the development of facial asymmetry, and a posterior open bite on the affected side. In this case, we treated an osteochondroma of Lt. mandibular condyle through excision of the lesion via the temporal approach to the temporomandibular joint.

Squamous papilloma is a benign proliferation of stratified squamous epithelium, resulting in a papillary or verruciform mass. Verrucous carcinoma is a differentiated variant of squamous cell carcinoma and may present diagnostic difficulties as it may be erroneously diagnosed as squamous papilloma. Squamous papilloma is similar to other oral mucosa malignancy in microscopic view. So, it is difficult to distinguish between squamous cell papilloma and other oral mucosa malignancy. Here are three patients. they were diagnosed as squamous papilloma initially, but the lesion was recurred. In recurred lesion, verrucous carcinoma or squamous cell carcinoma were found. So we report that recurred oral mucosa malignency(verrucous carcinoma or squamous cell carcinoma) which was diagnosed as squamous papilloma.
