Dental infections and maxillary sinusitis are the main causes of osteomyelitis. Osteomyelitis can occur in all age groups, and is more frequently found in the lower jaw than in the upper jaw. Systemic conditions that can alter the patient's resistance to infection including diabetes mellitus, anemia, and autoimmune disorders are predisposing factors for osteomyelitis. We report a case of uncommon broad maxillary osteonecrosis precipitated by uncontrolled type 2 diabetes mellitus and chronic maxillary sinusitis in a female patient in her seventies with no history of bisphosphonate or radiation treatment.

Purpose : To assess the clinical findings and hard tissue changes of osteomyelitis of the jaws using computed tomographic (CT) image analysis. Materials and Methods : We reviewed and interpreted the CT images of 163 patients (64 males and 99 females, age range from 10 to 87 years) who visited the Seoul National University Dental Hospital from April 23, 2006 to December 31, 2008 and were diagnosed as osteomyelitis of the jaws through clinical, radiologic, and histopathologic examination. Each CT findings was investigated for frequency, correlation with age and gender. Results : Of the 163 patients, 31 (19.0%) were affected on the maxilla, 135 (82.8%) were affected on the mandible, and 3 (1.8%) were affected on the both jaws simultaneously. The mean age of the patients who were affected on the maxilla was 61.0 years and that of the patients who were affected on the mandible was 56.2 years. On the maxilla, the most frequent site of disease was the posterior area (83.9%) and on the mandible, mandibular body (83.0%), followed by angle (48.1%), ramus (38.5%), condyle (13.3%), incisal area (9.6%), and coronoid process (3.0%). Among the 31 maxillary osteomyelitis, defect in the trabecular bone was observed in 28 (90.3%), osteosclerosis 20 (64.5%), defect in the cortical bone 27 (87.1%), sequestrum 17 (54.8%), and periosteal reaction 2 (6.5%). Among the 135 mandibular osteomyelitis, defect in the trabecular bone was observed in 100 (74.1%), osteosclerosis 104 (77.0%), defect in the cortical bone 116 (85.9%), sequestrum 36 (26.7%), and periosteal reaction 67 (49.6%). Conclusion : Of our cases, the maxillary osteomyelitis was visibly observed more frequently in females than males. The incidence is the highest in seventies (28.8%) and the lowest in teens (3.1%). The osteomyelitis of the jaws was observed more frequently in males than females before the age of 50, and observed more frequently in females after the age of 50. The most noticeable point was that the sequestrum was observed more often on maxillary osteomyelitis and the periosteal reaction was observed more often on mandibular osteomyelitis.

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.

Osteomyelitis in the oral and maxillofacial area is a relatively uncommon inflammatory disease that occurs due to odontogenic causes such as endodontic infection, facial trauma, insufficient blood supply caused by some medical conditions, and iatrogenic postoperative infections. Among them, the incidence rate of candida osteomyelitis in this area is minimal; therefore, no consensus on the diagnosis, treatment, and prognosis has not been established yet. With the increasing number of immunocompromised elderly patients, candida osteomyelitis of the jaw is expected to become more prevalent. In this case report, we present an 81-year-old male patient with candida osteomyelitis of the jaw, including the maxillary and ethmoid sinuses.

The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis. viral infections such as herpes zoster and fungal infections such as mucormycosis, aspergillosis etc. Herpes zoster is a common viral infection, the oral soft tissue manifestations of which are widely known and recognized. Extremely rare complications such as osteonecrosis, and secondary osteomyelitis in maxilla were observed. But, reports of spontaneous tooth exfoliation and jaw osteonecrosis following herpes zoster infection in the distribution of the trigeminal nerve are extremely rare in the literature. We report a case of maxillary necrosis by herpes zoster in an uncontrolled diabetic patient. There was extensive necrosis of the buccal and palatal mucoperiosteum and exposure of the alveolar bone. This patient was successfully treated using a removal of necrotic bone and nasolabial flap. We briefly discuss different diseases which can lead to maxillary necrosis and a review. Analysis of the pathogenesis of herpes zoster and bone necrosis are discussed.

Osteomyelitis is an exhaustive disease whose main feature is an inflammation of inner part of bone, bone marrow. In oral and maxillofacial area, we have maxillary and mandibular osteomyelitis and the latter is dominant because of its impaired blood supply. The main cause of osteomyelitis is a bacterial infection and the ways of infections are by periapical odontogenic infection, fracture, post-operative complication, and periodontal disease. The predominant etiologic factor is periapical odontogenic infection mostly caused by advanced dental caries. It is generally believed that periodontal disease could be a cause of osteomyelitis. But periodontal disease is usually confined to the alveolar bone area and not extends to the underlying bone marrow. Accordingly periodontal infection per se rarely cause produce oseomyelitis. Even though osteomyeltis could be occurred by periodontal disease, its virulence of infection is milder than periapical odontogenic infection. So it usually provokes sclerosing or hyperplastic osteomyelitis rather than suppurative type. We had a case of suppurative osteomyelitis caused by periodontal disease and treated it with periodontal and oral and maxillofacial surgical method.

Maxillary sinusitis is an infectious disease which can arise from odontogenic etiology and a maxillary osteomyelitis can spread into the sinus and consequently develop maxillary sinusitis. In this case report, a mid eighty's lady was diagnosed as BRONJ with maxillary sinusitis as a complication. The patient was managed successfully in collaboration with a endocrinologist. Through serial follow-up of serum CTX, we could decide the timing of surgical intervention.

Acute osteomyelitis of the maxilla with orbital cellulitis is occasionally seen secondary to a buccal infection, dental infection or necrotic process of the maxillary antrum. A case of acute osteomyelitis of the maxilla with orbital cellulitis in 5 years old boy has recently been experienced and cured by immediate incision and drainage combined with adequate antibiotics therapy. This paper was attempted to report the case with a brief review of reference.

The authors observed a 33-year-old male patient who had suffered from osteopetrosis with maxillary osteomyelitis. The obtained results were as follows: 1. Physical examination revealed hepatosplenomegaly and bowing legs. 2. Nearly all bones of the entire skeleton showed unusual increased radiodensity and the paranasal sinuses were markedly obliterated. 3. There were seveal old fractured sites in the femur and hip bones and subluxation of hip joint. 4. The radiodensity of both jaws were prominently increased and there were many malformed teeth and impacted teeth. 5. Bone scan revealed multiple, irregularly increased uptakes in large joints and long bones.

Osteopetrosis is a rare bone disease characterized by systemic osteosclerosis due to an osteoclast dysfunction that decreases bone resorption. This report demonstrates two cases of adult osteopetrosis with secondary osteomyelitis of the maxilla, in siblings who are 43-year old female and 55-year old, male respectively. The common radiographic features of these cases were increased radiopacity in skull, rib and vertebra. The radiographic features that differed between these two cases were the osteosclerotic pattern of the jaw bones, that is, diffuse patterns in the female case, while the male case showed nodular patterns that were confined to the root apices. The diagnosis of osteopetrosis may be complicated due to the varying degree of osteosclerosis on panoramic radiograph. Additional radiographs such as the chest and skull radiograph may be helpful for the diagnosis of osteopetrosis.
