Mediastinum is the space located between the right & left lung lobes in the center of the thorax, and contains many vital organs such as heart, aorta, trachea, esophagus, vagus nerve, lymphatics. So the infection of mediastinal space causes a serious and potentially fatal process. Like other infections, surgical drainage, aggressive antibiotic therapy and supportive care are recommended for optimal outcome. Airway management in the presence of the neck, glottic edema, elevation of the tongue is a formidible problem especially in the case from odontogenic origin. We have recently encountered such a case resulting in a number of local and systemic complications.

Pyogenic orofacial infections are most commonly odontogenic in origin. Although such infections are usually self-limiting and spatially confined, purulent material may occasionally borrow deeply into contiguous fascial space or planes far from the initial site of involvement. The incidence of orofacial infection remains low in this modern era of preventive dental care and antibiotic therapy, but severe orofacial infections are most frequently observed in the medically compromised patients. We experienced 5 cases of severe orofacial odontogenic infection associated with medical diseases, and then concluded as follows : 1. The average hospitalized period was about 5 weeks, and the signs that indicated that the infections were controlled usually appeared in third week after incision and drainage. 2. The involved medical diseases were diabetes mellitus iatrogenic Cushing's syndrome, rheumatoid arthritis, malnutrition, etc. 3. The medical diseases should be treated coincidently with control of infection.

The dentigerous cysts originate through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium, or between this epithelium and the tooth crown. Next to the radicular cyst, they are the second most common type of odontogenic cyst. They occur over a wide age range with a peak frequency in the 2nd to 3rd decade. A substantial majority involve the mandibular third molars, followed in order of frequency by the maxillary permanent canines, mandibular second premolars, and maxillary third molars. With regard to the treatment of these cysts, the marsupialization procedure with obturator is recommended during the age when the eruptive force of the teeth is still strong. It can be effective when preservation of the displaced teeth is desirable. We treated the dentigerous cyst by marsupialization with obturator and guided the eruption of involved teeth to normal position. And we got the results as follows : 1. Severely dislocated teeth associated with dentigerous cyst erupted into proper position. 2. The enamel hypoplasia and the root deformity were observed some cases. 3. The bone expansion and defect were healed without infection and recurrence.

Osteomyelitis means inflammation of the bone marrow. It usually begins in the medullary cavity, involving the cancellous bone; then it extends and spreads to the cortical bone and eventually to the periosteum. The cause is usually thought to be microbiological. But there still are factors that predispose to produce a possible bone infection such as injuries, syphilis, actionomycosis, chronic kidney failure, alcoholism, malnutrition, radiotherapy, and chemotherapy. Treatment of modalities have been directed toward eradicating microbes and improving circulation in the early stage. In the case presented, surgical debridement and IV antibiotics were the treatment of choice. Osteomyelitis in children is mainly affected in the mandible. And in childhood, the mandibular condyle is regarded as an important center of mandibular growth. Therefore, in young patients, osteomyelitis involving this region may cause a restraint of mandibular development, resulting in facial asymmetry. So diagnosis in the early stage is important in child with osteomyelitis. Recently, we have encountered an interesting case of osteomyelitis of the mandibular condyle in 9-year-old boy. So we present the case and review the literature about osteomyelitis.

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.

Infections in oral and maxillofacial region are relativley common and self-limiting, but in some cases, infections spread to adjacent hard and soft tissue and to cause any complication, even threaten life. So we made retrospective study of patients with interfascial infection who had been hospitalized and been treated by surgical treatment in Dankook university about 10 years. We reviewed the charts of patient with interfascial infection from 1995 to 2005. The result were as follows: 1. In gender & age distribution, male(54.2%) & fouth decade were most frequently. 2. The most common cause of infection was dental caries(55.2%) and the most of involving teeth was lower posterior teeth(44.1%). 3. Submandibular space is most frequently involving space and most infection involved mainly one space. 4. The patients with systemic disease were 38.2%. Diabetic mellitus was 87.2% of systemic diease. The admission period was 19.5 days in systemic disease. 5. The most microorganism in culture was Streptococcus Viridans(36.2%) in all patient. Klebsiella Pneumoniae was found most in Diabetic Mellitus. 6. The patient were mainly treated I&D on admission day. Of them 5(1.1%) patients were received tracheostomy. 7. Serum albumin, CRP and body weight are associated with Nutritional Risk Index(NRI). High risk patient group according to NRI classification showed higher rate of complications & mortality. 8. The patients with complication were 28(6.7%) persons. 4(0.9%) patients were expired. Nutritional Risk Index was helpful to predict the prognosis. When interfascial infection starts to spread, we must pay attention to airway management. Fluid therapy with nutritional may support to healing of wound.

Herpes zoster, an acute viral infection produced by the varicella zoster virus, may affect any of the trigeminal branches. This case report presents a patient with symptoms mimicking odontogenic pain. No obvious cause of the symptoms could be found based on clinical and radiographic examinations. After a dermatologist made a diagnosis of herpes zoster involving the third trigeminal branch, the patient was given antiviral therapy. Two months later the facial lesions and pain had almost disappeared, and residual pigmented scars were present. During the diagnostic process, clinicians should keep in mind the possibility that orofacial pain might be related to herpes zoster.

Descending necrotizing mediastinitis (DNM) is a complication of odontogenic or oropharyngeal infections that can spread to the mediastinum. Such infections is serious, leading to sepsis and frequently to death. Even in this era of antibiotics, the mortality rate associated with DNM is approximately 40%. It is difficult to diagnose early because clinical and radiologic findings appear in the late stage of the infection. Delayed diagnosis is the principal reason for the high mortality in DNM. Therefore, descending necrotizing mediastinitis requires an early and aggressive surgical approach to reduce the high morbidity and mortality associated with this disease. We experienced a case of odontogenic infection followed by acute mediastinitis, so present now with the review of literatures.

Malignant lymphomas are neoplasms with diffuse proliferation of neoplastic lymphocytes and their precursor cells. Diffuse large B-cell lymphoma, which is a subtype of non-Hodgkin's lymphomas, rarely occurs in the head and neck area and is especially rare in the maxillary sinus. We report a case of a 76-year-old female patient who was referred to the oral and maxillofacial surgery office for evaluation of a dental abscess as a clinical diagnosis. Laboratory tests revealed no signs of inflammation or infection; therefore, incisional biopsy was performed. The final diagnosis was diffuse large B-cell lymphoma in the maxillary sinus. Here we describe this case with a review of relevant literature.

A 61-years old man with diabetes mellitus(DM) was admitted to our hospital, complaining of progressive right periorbital swelling, headache and toothache on the right lower second molar. On the first visit, moderate swelling was noticed from the right periorbital region with exophthalmos and subconjunctival effusion. Intraorally, right lower second molar had a severe periodontal disease and fistular formation on its distal area. From 3 days after hospitalization, the visual acuity of his right eye was gradually worsen and we performed CT scan. CT scan demonstrated an inflammatory change at the right orbit with subperiosteal abscess at the inferior orbital wall, which was extended from the right infratemporal, parapharyngeal and internal pterygoid space. Patient was treated by mean of intraoral(right upper vestibular and retromolar) and extraoral(infraorbital) incision and drainage, massive anti-therapy and DM control. The patient improved gradually and finally was discharged from the hospital, but his visual loss of right side was not recovered.
