In order to determine the factors influencing outcome following craniotomy for trauma in patients over the age of 65 and to establish criteria for surgical intervention, the authors carried out a retrospective analysis of the hospital and general practice records of all head injury patients over the age of 65 who underwent a craniotomy for evacuation of a post-traumatic haematoma within 7 days of injury at Frenchay Hospital during a 10-year period (1980-89). Outcome was measured using the Glasgow Outcome Scale and patients were allotted to a good outcome group (good recovery or moderate disability but independent) or a poor outcome group (severe disability, vegetative state of death). There were 35 men and 31 women with a mean age of 72.5 years (range 65-85 years). ⋯ Outcome was significantly worse in the older patients (75-85 years) compared with the younger patients (65-74 years) and in those patients requiring craniotomy within 24 hours of injury, but the mechanism of injury (fall or road traffic accident), the presence or absence of skull fractures and limb fractures and the pre-operative CT scan appearances did not influence outcome. This study confirms the high probability of poor outcome following surgical evacuation of traumatic intracranial haematomas for elderly head-injured patients with pupillary dilatation or extensor motor responses. Craniotomy under these circumstances is not justified.

Retrospective and epidemiological studies have suggested that smoking increases the risk of developing aneurysmal subarachnoid haemorrhage (SAH). During 1990, 217 patients presenting to the Mersey Regional Neurosurgical unit with spontaneous SAH were prospectively studied. ⋯ Management outcome at 6 months following aneurysmal SAH was similar for smokers and non-smokers (p = 0.43) but smokers had more postoperative pulmonary complications requiring ventilation. Significance was tested with chi-square tests.

A retrospective analysis of 34 patients who underwent microsurgical therapy for craniopharyngioma from 1975 to 1989, a period when CT imaging was routinely used, is presented. Mean follow-up was 6.4 years with no patients lost to follow-up. Those who underwent subtotal resection with adjuvant radiation had a significantly better recurrence-free interval compared with those who either underwent total or subtotal surgical resection only (p < 0.05 and p < 0.025). ⋯ Those with subtotal resection and radiation had a 12% rate of recurrence. Endocrine and visual deficits were common after surgery. Based on this review, our results suggest that with a policy of attempted total resection where possible, subtotal removal along with adjuvant radiation, in cases where total resection was deemed unsafe, may be more effective than aggressive total resection alone as the initial management of craniopharyngioma.

During a 6-year period (1984-89), 31 patients were treated at Rambam Medical Center with penetrating craniocerebral injuries (PCCI) not associated with military action. Eighteen (58%) patients died during their initial hospitalization; only two of them had admission Glasgow Coma Scale (GCS) above five. The admission GCS coupled with the mode of injury (type of missile and motivation of shooting) were valuable for early accurate prognosis assessment. ⋯ The neurological status, CT appearance, as well as the motivation of shooting should be considered in order to assess accurately the possible outcome. Compared with our military series of 113 patients with PCCI, there were more extensive injuries, although the mean period until neurosurgical treatment was the same. Long-term complications connected to dural tears remote from the entrance wound occurred in three of the survivors.

The effects of high velocity missiles are described. A series of cases of craniocerebral tangential gunshot wounds over a 6 year period is presented with unsuspected cerebral contusion shown by CT. ⋯ The short- and long-term sequelae and the extent of cerebral damage belie the innocent appearance of the scalp wound. This influences the management of this unusual type of head injury.
