Squamous cell carcinoma (SCC) arising within the lining of an odontogenic keratocyst (OKC) is a rare occurrence. Although potentially locally destructive, OKC is a benign odontogenic process that typically presents with clinical and radiographic features characteristic of a benign intraosseous neoplasm. We present the clinical and radiographic features of a maxillary mass that demonstrated SCC arising from the lining of an OKC. Although the initial clinical and radiographic presentation suggested an infection or malignant neoplasm, biopsies revealed an infiltrative well-differentiated SCC contiguous with and arising from the focus of a pre-existing OKC. The patient subsequently underwent a type II hemi-maxillectomy with neoadjuvant chemoradiation. This report discusses the clinical and radiographic features associated with intraosseous malignancies, especially those arising from an otherwise benign odontogenic lesion. While the majority of OKCs are benign, the current report illustrates the potential for carcinomatous transformation within the lining of an OKC.

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.

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.

치성감염에 의한 이차적인 후측인두부나 종격동 감염은 매우 드물게 나타나지만 이러한 감염은 초기의 정확한 진단과 즉각적인 치료가 매우 중요하다. 이의 진단을 위해서는 후측인두부 감염시에 나타나는 임상증상을 잘 이해하고 주의깊은 환자의 관찰을 요하며 전산화 단층촬영이 질환의 진단과 치료에 매우 유용하게 이용될 수 있다. 후측인두부나 종격동 농양 형성시에는 적절한 항생제요법과 광범위한 외과적 배농 그리고 세심한 술후 처치가 치료의기본이 된다. 저자들은 치성감염에 의해 후측인두 및 종격동 농양이 발생된 3명의 환자에서 이를 조기에 진단하고 광범위한 외과적 배농과 적절한 항생제요법을 시행하여 양호한 치료 결과를 얻었다.

Hyperventilation is defined as ventilation in excess of that required to maintain normal blood $PaO_2$ and $PaCO_2$. It is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, two cases of hyperventilation were occurred during local anesthesia for incision and drainage of acute odontogenic infectious lesions. We suggest that the dental patients with acute odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.

Osteomyelitis is the inflammatory disease occured in the bone, involving a bone marrow, a Harversian system and the underlying cortical bone. Osteomyelitis is divided into acute and chronic osteomyelitis. Chronic osteomyelitis. is presented as a pain, swelling, pus discharge and radiographic change. The pathogenesis of osteomyelitis occcuring in the facial bone is predominately due to odontogenic microorgarnisms, Staphylococcus, resulted in odontogenic infection or post-traumatic infection. The mandible is the most commonly involved facial bone and the bones in the middle of third of the face is rare because of a abundant blood supply. Moreover, Osteomyelitis occuring in the zygoma is extremely rare. In our department, we report the case that osteomyelitis occuring in the zygoma with diabetes is resulted by odontogenic maxillary sinusitis.

Odontogenic maxillofacial space abscess in childeren was treated by the surgcal intervention combined with antiboitic therapy. Followings are the results after monitoring its progression. 1. Maxillofascial space abscess is mainly from the odontogenic infection and it may result in the severe states with the various fascial spaces and their relatives. So their early detection and treatment are needed. 2. The most common symptom in patients was the pain under palpation with painful swelling and the mouth floor elevation was observed in the sublingual space abscess. 3. In most cases, for its treatment, symptomatic therapy, antibiotic therapy, surgical incision and drainage were executed. If the infected tooth is possibly conserved, endodontic treatment is preferred, otherwise, it will be extracted as soon as possible.

Infectious myositis, an infection of the skeletal muscles, is a rare condition and potentially life-threatening if not detected and treated in the early stages. This clinical entity may arise from various pathogens, such as bacteria, fungi, parasites, and viruses. A propagation of contiguous infection, penetrating trauma, vascular insufficiency, or hematogenous spreading of microorganisms can cause infectious myositis. Though several cases have been reported in large muscle groups in the lower extremities, there are only a few reports on infectious myositis of the masticatory muscles. We report three cases of infectious myositis presenting jaw pain and trismus. Unlike a common head and neck infection caused by the spreading of odontogenic origin, the early diagnosis of infectious myositis was difficult because no specific lesion suspected to be the infection source was observed in the physical examination and the plain radiographs. Advanced imaging modalities such as computed tomography and magnetic resonance imaging, and laboratory evaluation is useful for the early detection of infectious myositis.

A 47-day-old male infant presented with fever, poor oral intake, irritability, and right-sided bluish buccal swelling. Contrast-enhanced computed tomography of the neck showed a round mass lesion of about $2.0{\times}1.5cm$ that suggested abscess formation in the right masticator space. Ultrasound-guided extraoral aspiration of the abscess at the right masseter muscle was successful. Staphylococcus aureus was identified in the culture from the aspirated pus and blood. Appropriate antibiotics were given and the patient recovered. The patient underwent follow-up ultrasonography that showed an improved state of the previously observed right masseter muscle swelling at about 1 month after hospital discharge. A masticator space abscess usually originates from an odontogenic infection in adults. We report a case of masticator space abscess in a 47-day-old infant in whom septicemia without odontogenic infection was suspected.
