Treatment of infected mandibular fracture is confronted with various difficult problem, e.g. nosocomial wound infection, non-union of fracture, osteomyelitis. Recently, nosocomial infection has become a major health problem because of excessive morbidity, personal distress, and cost. Frequently, isolated causative microorganisms of nosocomial infection were staphylococcus aureus, pseudomonas aeruginosa, klebsiella species. The various manifestation of the disease related to the pathogenesis and the clinical course tend to give a bad prognosis after operation. This is a report of case that post-operative infected mandibular fracture in 53-year-old man was not healed even through aggressive I & D and antibiotic treatment.

A resorbable barrier membrane is commonly used for the repair of perforated sinus membranes during sinus lifting surgeries. However, repairing largescale perforations poses challenges for clinicians as the protection and isolation of graft material remain uncertain. With this technique, we aimed to prevent graft material loss and subsequent sinus-related complications using intra-sinus rigid fixation of the resorbable barrier membrane in cases with a large perforation of the sinus membrane.

Because sublingual region is well-vascularized and sublingual artery is passed throughout this region, it should be careful not to perforate lingual cortex when placing dental implant on mandible. A 83-years-old male complained severe sublingual hematoma, hemorrhage and dyspnea came our outpatient department. He had received dental implant placement in the same day. He needed hemostasis and airway control. If soft tissue of sublingual region and the artery are injured, it may result in life-threatening excessive hemorrhage. In dental implant surgery, especially mandible, we should recognize the accurate shape of mandible and anatomy of sublingual region. It is important to stop anticoagulant agent before surgery. When a patient has airway obstruction, the operator should manage airway quickly.

Management of maxillofacial trauma includes primary care, in which diagnosis and management of dentoalveolar injury play a vital role. Due to the impact sustained during a maxillofacial injury (whether direct or indirect), dentoalveolar injuries can occur, leading to fracture and displacement of teeth and associated alveolar bone into the surrounding soft tissues and associated structures, such as the maxillary sinus, nasal cavity, upper respiratory tract, tracheobronchial tree, or gastrointestinal tract. Undiagnosed displaced teeth may cause complications such as airway obstruction. This paper reports a case of displaced teeth in the nasal cavity and gastrointestinal tract and highlights the management protocol for displaced teeth secondary to maxillofacial trauma.

Ameloblastomas are generally considered to be benign tumors of odontogenic epithelial origin with high local recurrence. Rarely ameloblastomas exhibit malignant behavior with development of metastases. In this report, we present a 19-year-old woman with ameloblastoma in the right ascending ramus and multiple recurrences. Eleven years after first therapy, ameloblastoma metastasized to ipsilateral submandibular lymph node. We also review literature about cause, treatment and work-up of malignant ameloblastoma.

The purpose of this study is to report on five cases treated with bone graft using recombinant human bone morphogenetic protein-2 (rhBMP-2) on jaw defects after cyst enucleation. We performed bone graft with BMP (rhBMP-2+${\beta}$-tricalcium phosphate/hydroxyapatite) wrapped with a collagen sponge on jaw defects after cyst enucleation. Postoperative panoramic radiographs were taken periodically. After 1 to 12 months, bone remodeling was observed in the jaw defect area. In our cases, there were few signs or symptoms of recurrence of the cyst during the follow-up period.

Fibrous dysplasia is a chronic developmental disease of the skeleton involving formation of immature bone. Involvement of facial bones can result in deformation of facial contour. Prominent cheek area is often treated with malarplasty, which has a variety of modifications, depending on the surgeon's preference. The authors report on a case of polyostotic fibrous dysplasia in which the patient's right cheek had a prominent appearance. The prominence was corrected with malarplasty without internal fixation. The soft nature of bone involved in fibrous dysplasia could provide greater flexibility for modification of the traditional surgery.

This is a case report and review of literature that deal with a surgical correction of mandibular deficiency. Patient, 38 years old male, had visited to treat mandibular deficiency. On the basis of clinical and radiographic examination, he was diagnosed as a micrognathia. Surgical method. 1. Intraoral Bilateral sagittal split osteotomy 2. Augmentation of genioplasty - double step. Patient was satisfied with final esthetics by gnathosurgery.
