Loss of mandibular continuity due to neoplasm, trauma, or infection results in major esthetic and biologic compromise. The use of costochondral grafts for reconstruction of temporomandibular joint, described first by Gillies in 1920, has been accepted as a suitable method for replacing the mandibular condyle, especially in growing children. Autogenous iliac bone graft has been a satisfactory source of mandibular reconstruction since Sykoffs report in 1900. Autogenous bone grafts from the posterior aspects of the ilium provide large amount of PMCB with acceptable donor site morbidity. In timing of reconstruction, initial disease, age, medical history, growth and development, esthetic and psychologic factors should be considered. We present a case of osteosarcoma in the mandible that was treated by a hemimandibulectomy and the defect was reconstructed 20 months later with composite method of costochondral and posterior iliac bone graft.

Periosteum in general is described as a specialized fibrous membrane of mesenchymal origin consisting of two basis layers : outer fibrous layer consists of irregularly arranged dense connective-tissue with fibroblasts, and inner osteogenic or cambial layer is composed of more loosely arranged fibers, greater vascularity and flatted spindle-shaped pre-osteoblasts. This periosteum may serve in controlling bone growth, especially mandibular growth has been emphasized. But, the periosteum enwrapping the facial skeleton have been studied for many years leaving a controversy in opinion regarding the function of these structures. We evaluated the bone formation activity of te periosteum in allogeneic bone grafts which bones are made of freeze-dried preparation preoperatively. We made the calvarial bone defects, 5 ${\times}$ 7mm sized, amd grafted with allogeneic bone in rats, which a half of specimens has dissected the overlying periosteum and a rest intacted. After bone grafting, we evaluated the capacity ofbone formation of periosteum, 1, 2, 4, 6, 8 weeks postoperatively. There are subtle differences of bone formation during early healing period after demineralized allogeneic bone grafting between control groups with periosteum and experimental groups without periosteum.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Ribs, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows ; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From march to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.

Vscularized calvarial bone flaps have been useful tools in the reconstuction of different type of bone defects in craniofacial surgery Vascularized bone transfer are often preferred to nonvascularized bone grafts because nonvascularized bone grafts are less resistant to infection, not as mechanically strong, and do not survive well in a poorly vascularized bed. Potential advantages of vascularized outer table calvarial bone flap include proximity to the operative field, membranous origin similar to that of the facial skeleton, maleability which allows for a variety of shapes and sizes, inconspicous donor sit scar. The following are the case reports of two patients who underwent craniofacial reconstruction suing vascularized outer table calvarial bone flap.

It is difficult to obtain a satisfactory bony union of large bone defect secondary to trauma, tumor resection, congenital pseudarthrosis of tibia and bony metaplasia following infection with conventional methods. Conventional nonvascularized autologous bone graft do not provide adequate large amounts of donor bone and usually undergo necrosis or nonunion due to lack of vascular nutrition. Currently, advanced in microsurgery have made it possible to provide a continuing circulation of blood in bone grafts so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. Thus, the grafted bone is achieved more rapid stabilization without sacrificing viability. We reviewed 11 cases of vascularized fibular grafts which were performed from December 1982 to January 1993 and the following results were obtained: 1. Large bone defects with chronic osteomyelitis secondary to trauma were could be successfully treated by the vascularized fibular transfer. 2. In our experience, the vascularized fibular transfer was thought to be one of good methods of treatment for congenital pseudathrosis of tibia. 3. Complete tumor resection was followed by a free vascularized fibular transfer, resulting in good functional improvement, without local recurrence. Long bone defect secondary to bony dysplasia was could be reconstructed by the vascularized fibular transfer. 4. The transferred vascularized fibula had been hypertrophied with bony union during follow-up period and there was no resorption of the grafted fibula.

Objective: The sinus floor elevation procedures have been used to facilitate implant placement in the severely atrophic posterior maxilla. Many variables may have an influence on the outcomes of the sinus floor elevation in combination with implant treatment. The aim of this study was to analyze survival rate of implants placed in the edentulous maxillae of patients in whom sinus floor elevation was undertaken according to variables. Materials and Methods: It consisted of 96 patients(50 male and 46 female), ranging in age from 31 to 70 years(mean 49 years), who underwent sinus floor elevation procedure(94 implants in left side and 106 implants in right side) from 2001 to 2002. A total of 200 implants were placed in the grafted sinus(73 implants in lateral approach and 127 implants in crestal approach). All implants were restored by fixed prosthesis. All patients were healthy. Follow-up periods for implants were between 48 to 60 months. Results: The cumulative survival rate of implants was 91.5%. Gender, age and operation site did not have an influence on the survival rate. There was statistically significant differences for the implants which placed in less than 4 or 5 rom residual bone height, the survival rate was 60%, 81.4% respectively (p<0.05). There was no statistically significant difference of implants survival rate ac- cording to approach technique. The survival rate for 100% autogenous bone grafts was lower with respect to composite grafts containing autogenous bone and 100% substitutes. The survival rate for hydroxyapatite-coated implants was statistically significant lower than other textured group (p<0.05). Conclusion: Residual bone height, surface texture and graft materials have an influence on the survival rate. To use autogenous bone as a part of a composite bone replacement, implant texture which leads to more favorable implant-bone interface were necessary. To determine residual bone height for initial implant stability was important.

Numerous techniques of anterior cruciate ligament (ACL) reconstruction have been described in literature. All have inherent advantages and disadvantages. The central one-third patellar tendon and hamstring tendons are the most commonly used autogenous tissues for replacement of a torn anterior cruciate ligament. Although the central one-third patellar tendon is considered to be 'the gold standard' for replacement of torn ACL. equivalent results have been reported using hamstring tendon grafts. Autogenous hamstring grafts provide adequate strength while avoiding donor site morbidity associated with bone-tendon-bone harvest. $EndoButton^{\circledR}$ femoral fixation allows precise femoral tunnel placement without a second incison. The purpose of this article is to describe surgical techniques using a quadrupled semitendinosus tendon and $EndoButton^{\circledR}$ fixation, and review the results of replacement of ACL.
