Autogenous bone graft is the useful technique for management of various bone defect in oral and maxillofacial surgery. The most common site for bone graft harvest is the anterior iliac crest. There is usually considerable cancellous bone graft available and it can be obtained with minimal morbidity. However, complications noted in iliac crest grafts include prolonged postoperative pain, hematoma and fracture, gluteal muscle weakness. Occasionally, when large amounts of bone graft are needed and previous harvest procedure had used, iliac bone harvest may be not adequate. Like the iliac crest, the greater trochanter has abundant cancellous bone and is readily accessible with acceptable morbidity. The purpose of this study was to assess the availability of cancellous bone graft from the greater trochanter, compare the quantity with that available from the anterior iliac crest, investigate anatomical hazards, and make recommendations for consistent harvest.

The cemento-ossifying filbroma is a well-demarcated and occasionally encapsulated neoplasm composed of fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum, or both. The greatest number of cases are encountered during the third and fourth decades of life and there is a definite female predilection, with female-to-male ratios as high as 5 : 1 being reported. The mandible is involved far more than the maxilla, and 90 percent of all cases are located in the mandible. The mandibular premolar-molar area is the most common site. Radiographically, the lesion is most often well defined and unilocular. Depending on the amount of calcified produced in the tumor, it may appear as completely radiolucent : more often it shows varying degrees of radiopacity. Some lesions may be largely radiopaque with a radiolucent halo. On microscopic study, the tumor is composed of fibrous tissue of varying degrees of cellularity containing calcified material. This may be in the form of trabeculae of osteoid and bone or basophilic ovoid calcifications that resemble cementum-like material. Admixture of the two types of calcifications are commonly seen. On this case, large cemento-ossifying fibroma has grown in the mandible and this lesion was treated by complete surgical excision and posterior iliac bone graft. A review of literature and a report of a case of cemento-ossifying fibroma are presented.

The midfacial deficiency is usually accompanied with congenital craniofacial synostosis, such as Crouzon, Apert, Pfeiffer, Carpenter, Saethre-Chotzen syndrome, and so on. But sometimes isolated midfacial deficiency without cranial malformations may appeared, the cause of which is congenital, hereditary, or secondary to developmental factors, such as infection and trauma to middle face. Since Sir Harold Gillies reposted the first high maxillary osteotomy that alleviated the problems of total midfacial deficiency, the various operative methods were developed by many clinicians, such as Longacre and Tessier. These procedures can enlarge the orbital volume and decreases exorbitism. As middle face was moved forward, these functional, esthetic, and psychologic advantages were resulted from this. This is a case of midfacial deficiency corrected by the subcranial Le Fort Ⅲ osteotomy through only coronal approach.

Although the use of the antibiotics has minimized the dangers of the spread of odontogenic infection to adjacent important organs, sometimes the fatal cases, such as Ludwig's angina, mediastinitis, intracranial complications from the odotogenic infection, may be occurred. The odontogenic infections or oral and maxillofacial region may involve the intracranial area through systemic circulation or by direct spread into the intracranial cavity. Headache, malaise, loss of appetite, chills, fever, vomiting, apathy, and irritability are usually followed by more specific involvement of the nervous system. We experienced one patient who died of intracranial complication from odontogenic infection. So we report the case and the literatures about intracranial involvements following odontogenic infections and dental procedures.

As a society develops and a standard of living raises, the orthoganthic operation, the purpose of which is the harmony of oral and surrounding tissue, the improvement of the basal bony relations for stable tooth-support, and the improvement of facial appearance, generalized in our society. This is a clinical study on 135 patients who underwent orthognathic operation at the Dept. of Oral and Maxillofacial surgery, College of Dentistry, Kyung-Hee University during the last 5 years. The results were as follows. 1. The ratio of female to male was 1.4 : 1. 2. The age distribution of most patients was the period of 20 years thruogh 24 years. 3. The major reasons for seeking orthagnathic surgery were ethetic complanints(94.8%), and additional reason was functional complaints such as masticatory disturbances, phonetic disturbances, and TMJ discomfort. 4. In order to consult about orthognathic surgery, the patients first visited to the Dept. of oral and maxillofacial surgery at the ratio of 24.0%. 5. The ratio of the patients who underwent the presurgical orthodontic treatment was 79.5%, and the treatment usually required the period from 7 months to 18 months. 6. The setback amount was less than 10mm at the ratio of 85.8%. 7. The orthognathic operations which were practiced were usually composed of ramus osteotomy such as sagittal split ramus osteotomy and vertical ramus osteotomy and additional surgery on mandible at the ratio of 86.7%, and SSRO was done at the ratio of 62.5%, and EVRO was done at the ratio of 37.5%.

Maxillary duplication is a kind of proliferative neurocristopathy and considered to arise from bifurcation of neural crest elements soon after migration into mandibular arch. Sometimes this malformation is accompanied with oblique facial cleft. Usually this type of maxillofacial malformation requires multiple surgical intervention and the results are far from ideal. It became more troublesome if it had not been properly corrected on time, because secondary deformities could be developed from growth and development of abnormal tissues. This is a case of a 25-year-old-female patient who showed severe facial asymmetry thought to secondary deformity of maxillary duplication and masticatory disturbance due to multiple supernumerary teeth on posterior part right maxilla. We successully treated these deformities through four times of surgery of bone resection, orthodontic treatment, zygomatic and orbital reconstruction, orthognathic surgery and scar revision... ect. So we reported this rare case with review of literatures.

Maxillary cancer accounts for only 0.3% of all cancers and tumors of the nose and paranasal sinuses are 80% of maxillary neoplasms. The complexes of midfacial anatomical landmarks make the extension of the maxillary cancer more easy. In 1826 since Lazar first made unilateral maxillectomy for the maxillary cancer, various developments were evoluated and in the surgical approach of these lesions most oral & maxillofacial surgeons have used the vestibular approach or Weber-Fergusson approach and also unilateral lesions are common but bilateral lesons are rare. In 1992 Sjovall introduced the bilateral maxillectomy and for the preventions of the facial scar, In 1927 Portmann and Retrouvey reported the sublabial approach and In 1979 Price reported the midfacial degloving approach and in 1981 Allen and Siegel used the term "Midfacial degloving approach". Unlike the previous used Weber-Fergusson approach and Caldwell-Luc method, midfacial degloving method can make the intraoral approach of midfacial structure exposure without facial incision and has populated gradually for the removal of tumors and facial plastic surgery. In this case, two male pt. with bilaterally extensive malignant neoplasm on maxillary sinus was treated with pre or post op. radiotherapy and then underwent the bilateral subtotal maxillectomy via midfacial degloving approach and relatively satisfactory results were obtained.

The verrucous carcinoma which was classified by Ackerman in 1948 is generally well differentiated and slow growing. After its radical surgery, it is rarely recurrent of carcinoma. Tobacco chewing is a most important factor in the etiology of these lesion. It frequently affect males over 55 year old age and usually appears on buccal and mandibular alveolar mucosa. The continuing effort by plastic surgeon to reconstruc lips successfully has been accompanied by numerous publications on the subject. More recent communications have dealt with modifications or refinements of existing procedures. In 1974, Karapandzic reported the use of arterialied flaps to reconstruct lips following excisions of cancers. We have treated 65 year old male patient rapid growing verrucous carcinoma on lower lip with Karapandzic flap. Postoperatively the results showed good prognosis. So we report the result of its treatment and case with review of literature.
