This study comprised of 340 cases of extradural haematomas (EDHs) treated during a period of 10 years (1984-1994) in the division of Neurosurgery, Institute of Medical Sciences, Varanasi. Majority of them were rural patients (55.9 percent). The commonest mode of injury was blunt impact to the head mainly by lathi in rural India (48.4 percent), and road traffic accidents in urban population (60 percent). Only 12 percent of patients reached hospital within 6 hours of injury. Outcome is better in rural cases (11.5 percent) inspite of late reporting to the hospital. Such cases are not usually associated with other injuries as impact is focal. Clot with less than 50 ml, 50-100 ml and more than 100 ml had mortality rate 0 percent, 12.5 percent and 18.7 percent respectively; similarly outcome became poorer with increasing midline shift in computed tomography scan (1-4 mm: 0 percent, 5-9 mm: 9.2 percent and 10 mm or more: 29.8 percent). The common site of EDH is temporal (42.2 percent) in urban and parietal (51.6 percent) in rural patients.
