title: Chronic extradural haematomas: indications for surgery.
abstract: Non-invasive neuro-imaging has led to the detection of minimally symptomatic or asymptomatic chronic extradural haematomas. Our experience and review of the literature suggests that, as in the case of chronic subdural haematomas, there is development of membranes and liquifaction of the clot which may permit drainage of such collections through twist drill or burrholes. The time from development and the neuro-imaging chanes on CT and MRI can suggest the age and nature of the clot and thus permit timing of surgery so that drainage may be accomplished with a minor procedure.
