Posterior fossa extradural hematoma due to closed head injuries

ABSTRACT

Extradural hematoma of posterior cranial fossa that related to closed head injuries was rare and difficult diagnosis. The study involved 45 patients. 40/45 patients had signs of hematoma in occipital region, 34/45 patients had headache, 28/45 patients had vomit, 22/45 had dizziness, 30/45 patients had sleepy. 23 patients received X-ray imaging, in which, 11 patients showed the rupture of occipital bone. On CT images, rate of partial ventricular collapse and displacement was 95.6%. 28/45 patients with posterior fossa extradural hematoma had conscious duration. And in 18 patients this duration longed for more than 1 days. Perception worsened rapidly is a common sign of posterior fossa extradural hematoma, especially in acute hematoma. Mortality of posterior fossa extradural hematoma was 20%. Rate of patient without post-operative complication was 71.1%. Rate of patient with post-operative complication was 8.9%.
