Evaluation of simulated bone lesion in the head of the mandible by using multislice computed tomography.

Unlabelled: Conventional radiography has shown limitation in acquiring image of the ATM region, thus, computed tomography (CT) scanning has been the best option to the present date for diagnosis, surgical planning and treatment of bone lesions, owing to its specific properties.

Objective: The aim of the study was to evaluate images of simulated bone lesions at the head of the mandible by multislice CT.

Material And Methods: Spherical lesions were made with dental spherical drills (sizes 1, 3, and 6) and were evaluated by using multislice CT (64 rows), by two observers in two different occasions, deploying two protocols: axial, coronal, and sagittal images, and parasagittal images for pole visualization (anterior, lateral, posterior, medial and superior).

CT assessment of the correlation between clinical examination and bone involvement in oral malignant tumors.

Oral cancers have a tendency to invade the surrounding bone structures, and this has a direct influence on the treatment management and on outcomes. The objective of this study was to correlate the clinical parameters (location, clinical presentation and TNM staging) of oral malignant tumors that can be associated with a potential of bone invasion and determine the accuracy of clinical examination to predict bone involvement, using computed tomography (CT). Twenty five patients, with oral malignant tumors were submitted to clinical and CT examinations.

Nasopharyngeal angiofibroma. surgical approach using a transoral Le Fort I osteotomy following embolization: a case report.

Nasopharyngeal angiofibroma (NA) is a rare vascular benign nonencapsulated neoplasm, characterized by local aggressiveness and destructive potential, typically diagnosed in adolescent males. We report a case of NA affecting a 15-year-old male that presented with a persistent nasal obstruction and epistaxis with 1 year of evolution. Clinical and radiological patterns pointed out a differential diagnosis of NA.

Osteomyelitis of the mandible associated with autosomal dominant osteopetrosis: a case report.

Osteopetrosis is a rare hereditary bone disorder presenting with variable clinical features and is characterized by an increase in bone density. The main clinical findings of the benign-type of osteopetrosis (autosomal dominant) are fractures and osteomyelitis of the mandible, leading to the detection of the disease. We report a case of autosomal dominant osteopetrosis with secondary mandibular osteomyelitis.

Adult T-cell leukemia/lymphoma with predominant bone involvement, initially diagnosed by its oral manifestation: a case report.

Adult T-cell leukemia/lymphoma (ATL/L) is a rare malignant neoplasm linked to human T-cell lymphotropic virus type 1 (HTLV-1). This virus has been identified in Japan, the Caribbean, and, more recently, Brazil. We report a case of ATL/L (lymphoma-type) affecting a 30-year-old Brazilian woman.

Computed tomography assessment of Apert syndrome.

Apert syndrome, or acrocephalosyndactyly type I, is a craniofacial dysostosis, an autosomal dominant condition characterized by severe developmental disturbances of the craniofacial region including bilateral coronal synostosis associated with midface hypoplasia, exophthalmia, hypertelorism, and symmetric syndactyly of the hands and feet. The aim of this study is to assess the clinical and computed tomography imaging patterns of non-operated patients with Apert syndrome, correlating the bone abnormalities of the cranium, face and the skull base. The study population consisted of 5 patients with Apert syndrome.
