Traumatic extradural haematomas in pediatric age group.

A series of 75 children with traumatic extradural haematomas operated on at our Department between 1982 and 1988 were analysed in detail. The overall mortality rate was 17%. CT scan constituted a valuable tool for an early and correct diagnosis, and the mortality rate declined to 9% in the post-CT era. The outcome was found to be predominantly affected by the preoperative neurological status, by the duration of the time interval between onset of coma and surgical intervention, and mainly by the presence of associated brain lesions.
