Right frontal encephalomalacia The frontal pole is largely replaced with the high signal of cerebrospinal fluid left after liquifaction necrosis in this old infarct.
Findings: Smooth midline cavity separating the frontal horns of the lateral ventricles (anterior to the foramen of Monro) and appearing isodense with cerebrospinal fluid.
Further adding to occupant safety, frontal impacts are absorbed by crumple zones directed into Y-shaped chassis members and the main understructure – the strongest part of the chassis.
Performation of surgical procedures anterior to ethmoid bulla can avoid risks of the other models, therefore, endoscopic frontal sinusotomy in the route anterior to ethmoid bulla is a safe model.
