1/79. Maxillofacial osteonecrosis in a patient with multiple "idiopathic" facial pains.Previous investigations have identified focal areas of alveolar bone tenderness, increased mucosal temperature, abnormal anesthetic response, radiographic abnormality, increased radioisotope uptake on bone scans, and abnormal marrow within the quadrant of pain in patients with chronic, idiopathic facial pain. The present case reports a 53-year-old man with multiple debilitating, "idiopathic" chronic facial pains, including trigeminal neuralgia and atypical facial neuralgia. At necropsy he was found to have numerous separate and distinct areas of ischemic osteonecrosis on the side affected by the pains, one immediately beneath the major trigger point for the lancinating pain of the trigeminal neuralgia. This disease, called NICO (neuralgia-inducing cavitational osteonecrosis) when the jaws are involved, is a variation of the osteonecrosis that occurs in other bones, especially the femur. The underlying problem is vascular insufficiency, with intramedullary hypertension and multiple intraosseous infarctions occurring over time. The present case report illustrates the extreme difficulties involved in the diagnosis and treatment of this disease.- - - - - - - - - - ranking = 1keywords = osteonecrosis, jaw (Clic here for more details about this article) |
2/79. Computerized tomography in the management and follow-up of extensive periapical lesion.Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
3/79. Glandular odontogenic cyst. A rare entity with aggressive biological behaviour. A case report.Glandular Odontogenic cyst is an apparently rare jaw cyst characterised by typical histopathological features, propensity to reach large size and high rate of local recurrence, if not adequately treated. Identification of this cyst as a separate entity is important because of the difference in biological behaviour. We report a case of Glandular Odontogenic cyst occurring in maxilla.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
4/79. eosinophilic granuloma as a form of inflammatory reaction. A case report.eosinophilic granuloma consists of the proliferation and/or accumulation of langerhans cells in the bones, generally of the cranium and face, as a uni- or multifocal cystic lesion. It is considered to be a localized chronic form of Langerhans cell disease. The most frequent oral location is the posterior part of the mandible, where the bone lesion often gives rise to lesions of the overlying soft tissues. We report a case showing bilateral involvement of the upper jaw and unilateral involvement of the mandible. The eosinophilic granulomas arose in association with odontogenic periapical infectious processes, suggesting that this disorder may be a form of inflammatory response.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
5/79. eosinophilic granuloma of the jaws: a report of three cases.Three cases of eosinophilic granuloma involving two boys and a girl are reported. Osteolytic lesions of the jaws were seen in all three patients. The two boys presented mandibular lesions, while the girl had lesions in both jaws. Patient age at the onset of the disease was 6 and 9 years in the boys and 10 years in the case of the girl. The affected zone was painful to palpation in all cases, with intra- and extraoral swelling and bone bulging that caused slight facial deformity and bleeding of the gums. Biopsies were obtained in all three cases, and the histopathological study confirmed the diagnosis. The clinical course was favorable in all three children.- - - - - - - - - - ranking = 0.006726589722883keywords = jaw (Clic here for more details about this article) |
6/79. Rapid growth of giant cell granuloma in pregnancy treated with calcitonin.The giant cell granuloma of the jaws is a benign osteolytic lesion that may be treated by curettage, intralesional corticosteroids, or calcitonin. These medical treatments may be particularly useful when lesions arise in the immature facial skeleton, recur, or enlarge very rapidly-the last two situations being recognized complications of pregnancy. In this study, a patient is presented with a central giant cell lesion of the maxilla that switched from a relatively indolent growth pattern to become a rapidly enlarging and destructive lesion in the maxilla almost immediately after the patient became pregnant. Although calcitonin treatment is normally avoided in pregnancy, it proved highly effective, caused no obstetric or fetal side effects, and was not contraindicated by renal failure due to lupus nephritis. Histologically, the lesion was converted to a fibro-osseous lesion-like appearance. On the basis of the results of this case, calcitonin appears to be a safe, effective, and conservative treatment for giant cell granulomas that enlarge rapidly during pregnancy.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
7/79. Unusual jaw lesions in the paediatric and adolescent patient: a management challenge.While major maxillofacial pathology in the young patient is relatively uncommon, non-malignant conditions may pose a significant treatment dilemma due to their aggressive or unpredictable behaviour. Several such diseases managed by the Oral and Maxillofacial Surgery Unit at the Royal Children's Hospital of Melbourne have been selected for review. Illustrative case reports to highlight the principles of management are presented.- - - - - - - - - - ranking = 0.0044843931485887keywords = jaw (Clic here for more details about this article) |
8/79. osteonecrosis of the maxilla as a complication to chemotherapy: a case report.Numerous oral complications have been documented as a consequence of chemotherapy for the treatment of cancer. One not so well documented consequence of this treatment is avascular necrosis or osteonecrosis of the underlying bone. In this case report, osteonecrosis of the maxilla in a 48-year-old female patient who was treated for acute myelogenous leukemia is presented. The patient had successfully completed both induction and consolidation chemotherapy without steroid administration. Possible causes and difficulties in diagnosis were reviewed.- - - - - - - - - - ranking = 0.28539397191796keywords = osteonecrosis (Clic here for more details about this article) |
9/79. A review of odontogenic keratocyst with a report of unusual occurrence in the maxilla.Odontogenic keratocysts (OKC) are keratinizing epithelium-lined cycts of the jaws with well-defined histologic criteria and possessing one clinical feature warranting their recognition and separation as a distinctive entity, due to their exceedingly high recurrence rate. This report describes a case of OKC which occurred in the anterior maxilla in a 12 year old female child, with its treatment. These lesions are normally seen in the mandible, and are rare in the maxilla.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
10/79. Radiological features of glandular odontogenic cyst.OBJECTIVES: To present five new cases of glandular odontogenic cyst (GOC) and to review the radiological features at presentation as reported in the English literature. methods: From 1993 to 2002, five patients in our department were diagnosed with GOC based on histopathological findings and supported by radiography and CT. The radiographic features of the new GOC cases were analysed in addition to 51 literature cases. RESULTS: There were 31 male and 25 female patients, aged 14-90 years (mean 50 years). The mandible was involved in 80% and the maxilla in 20%; most of the lesions were located in the anterior jaw. Radiographically, 52% of the lesions were unilocular and 48% were multilocular; 94.5% showed well defined borders, which were sclerotic in 7.7% and scalloped in 13%. Information on cortical plate integrity was available in only 24 cases: 50% showed perforation, 8.3% erosion of the cortical plates and 8.3% thinning of the cortical plates. root resorption was reported in 22% of patients and tooth displacement in 24.4%. CONCLUSIONS: Data collected indicate that GOC has potentially aggressive behaviour, with expansion and perforation in a significant number of cases. We recommend the use of multiple plane radiographs, with CT reserved for large lesions, especially those that are multilocular or involve extragnathic structures.- - - - - - - - - - ranking = 0.0011210982871472keywords = jaw (Clic here for more details about this article) |
