Basal skull fractures. A prospective study of 100 consecutive admissions.
A prospective study of 100 consecutive patients with basal skull fracture admitted to the University Hospital, Kuala Lumpur between July 1986 and October 1988 was carried out to study its epidemiological pattern, clinical and radiological presentations, mechanisms of injury, time interval between accidents and neurosurgical referrals, complications and outcomes. Two-thirds of the patients were between 20 and 50 years old and 79% were male. Half of the injured were motorcyclists and 22% were pedestrians. Three-quarters of the patients were seen within an hour after injury. Thirty-two patients had intracranial haematomas: 14 subdural, 9 extradural and 9 intracerebral. Three patients developed meningitis (two after operations) and six developed epilepsy. Eighteen patients died, but good recovery resulted in 70 patients at follow-up of 1 to 28 months. A small subgroup of 15 patients with severe ear and nose bleeding as a result of basal venous sinus tear died within a few hours despite aggressive resuscitation, probably due to underlying severe brain stem injury. The implication of the high incidence of basal skull fractures in motorcyclists, despite the enforcement of crash helmets is discussed, with possible mechanisms proposed.
