Epidemiologic evaluation of mandibular fractures in the Rio de Janeiro high-complexity hospital.

The aim of this study was to gather data on trauma etiology and mandibular fracture localization in patients who presented at the General Hospital of Nova Iguaçu, Rio de Janeiro, Brazil. From March 2007 to December 2008, 95 patients with mandibular fracture were registered in a medical form, at the Bucomaxillofacial Surgery Department of the General Hospital of Nova Iguaçu, Rio de Janeiro, Brazil. Concerning mandibular fracture etiology, 21.

Utilization of surgical trepan for the obtainment of calvarial autogenous bone graft in maxillary reconstructions.

Maxillomandibular reconstructions are traditionally performed by means of autogenous bone grafts collected from intraoral donor areas and extraoral donor areas such as clavicle, iliac bone, rib, and tibia. The calvarial bone has been studied as an alternative donor area, with a low incidence of complications and minimal postoperative morbidity. Complications such as dural lacerations associated with cerebrospinal fluid leakage and extradural and subdural bleeding were minimized due to the use of surgical trepan, allowing the diploic layer delimitation before the osteotomy, preserving the internal calvarial cortical.
