PURPOSE Reduction and plate osteosynthesis of condylar fractures often require a wide extraoral approach with the risk of aesthetic impairment and possible facial nerve palsy. To avoid complications, the purpose of this pilot study was to use an endoscopic device for the treatment of condylar fractures also allowing for endoscopically assisted plate application. PATIENTS AND METHODS Seven con...

Skull fractures are quite often observed in victims of falls, traffic accidents, attacks with the use bats and rods. The aim study is to assess stress-strain state human head under impact on basis finite element modelling. applied frontal region bone by middle part end a cylindrical solid (a rod). differently oriented respect relation Frankfurt plane. model includes epidermis (skin), structures...

A method has been developed, which we call the "response probability density function technique," which has applications in predicting the probability of injury in a wide range of biodynamic situations. The method, which was developed in connection with sonic boom damage prediction, utilized the probability density function of the excitation force and the probability density function of the sen...

This study investigated the severity of injuries associated with falling from bed and the effectiveness of injury-prevention strategies. Injury criteria were calculated for head- and feet-first falls from six bed heights onto a tiled surface and floor mat. These values indicated a 25% chance of experiencing a serious head injury as a result of falling feet-first from a bed height of 97.5 cm ont...

We present two cases of orbital meningioma which were totally excised by a neurosurgical and craniomaxillofacial team using skull base approaches.

complication of skull fracture, occurring almost exclusively in infants and children under the age of three (1, 2). It follows head trauma with accompanying skull fracture. Dural tear associated with skull fracture is the basic mechanism by which this condition occurs. Growing skull fracture is most commonly observed in the frontal and parietal regions, but it can occur anywhere in the skull (3...

PURPOSE Electroencephalogram (EEG) source analysis is a noninvasive technique used in the presurgical of epilepsy. In this study, the dipole location and orientation errors due to skull conductivity perturbations were investigated in two groups of three-dimensional head models: A spherical head model and a realistic head model. METHODS In each group, the head model had a brain-to-skull conduc...
