UNLABELLED Facial integrity is a condition which interferes in the daily life of the individual. The loss of an eyeball has psychological impact, requiring adaptation. Interventions such as prosthetic repair seem to lead to emotional and behavioral change. PURPOSE The objective of this study was to identify the psychosocial aspects related to unilateral(More)
The aim of this research was to compare the condylar morphology of patients with unilateral condylar hyperplasia (UCH) and patients with a class III skeletal relationship using cone beam computed tomography (CBCT). A prospective study was conducted on patients with facial asymmetry attending the division of oral and maxillofacial surgery of the study(More)
Facial asymmetry is relatively common, but it becomes a disease when condylar hyperplasia is involved. The purpose of this investigation was to describe and compare the morphological characteristics of hyperplastic condyles to their nonhyperplastic contralateral side. Fifteen subjects aged between 14 and 29 years with facial asymmetry and diagnosed with(More)
Malignant fibrous histiocytoma is a sarcoma with rare occurrence in the oral and maxillofacial region; surgery is the most reliable treatment. Inadequate resection of the sarcoma on the oral and maxillofacial region is associated with a high incidence of local recurrence and a poor prognosis. Only few patients of malignant fibrous histiocytoma of the malar(More)
The diagnosis of synovial chrondromatosis of temporomandibular joint (TMJ) requires a combined assessment consisting of clinical, radiologic, and histopathologic examinations. The purpose of this study is to report in 1 patient the removal of a single large cartilaginous nodule floating in the upper joint compartment using arthroscopy. A 30-year-old woman(More)
OBJECTIVE Auricular prostheses are artificial substitutes for facial defects. The retention of these has often been a problem. This study aimed to evaluate the mechanical behavior of 3 retained auricular prosthetic connections when submitted to a mechanical cycling test. MATERIALS AND METHODS Twelve samples with installed implants were obtained and(More)
Extensive resection of tumor often results in bone and soft tissue defects that cause functional and esthetic consequences. The reconstructive surgery is extremely important for the rehabilitation of these patients. The purpose of this study is to report on the use of Hyperbaric Oxygen therapy (HBO) in the case of a large ameloblastoma treated with(More)
PURPOSE To compare the condylar volume of patients with unilateral condylar hyperplasia (UCH) with that of patients with a Class III skeletal relation. MATERIALS AND METHODS Twenty cone-beam computed tomograms of patients were analyzed. Images were divided into 2 groups: 10 from patients with transverse asymmetry of the face and 10 from patients with a(More)
OBJECTIVES The aim of this study was to compare the mechanical resistance of four different osteosyntheses modeled in two different sagittal split ramus osteotomy (SSRO) designs and to determine the linear loading in a universal testing machine. MATERIALS AND METHODS An in vitro experiment was conducted with 40 polyurethane hemimandibles. The samples were(More)
Obstructive sleep apnea is a common sleep-related breathing disorder of major public health importance. However, the treatment remains challenging. The current gold standard, particularly for moderate to severe cases, is continuous positive airway pressure, but it is often suboptimal because patients dislike it so do not tolerate it [1]. Thus, many surgical(More)
