How much monitoring is needed for basilar skull fractures?

Basilar skull fractures account for approximately 19% of all skull fractures. There have been little data published concerning the need for intensive care monitoring in this injury. We retrospectively studied 259 patients admitted to our trauma center over an 8-year period with a diagnosis of basilar skull fracture. All patients were evaluated with cranial computed tomographic (CT) scans. These patients were admitted to the trauma service, and neurosurgical consultation was obtained in all cases. The diagnosis was made by clinical signs in 207 patients (80%), by CT scan in 47 (18%), and by plain films in 5 (2%). Ninety-two patients (group I) had intracranial pathology in addition to basilar skull fracture. Twenty-one patients in this group underwent craniotomy. In this group, the morbidity and mortality rates were 11% and 7%, respectively. Forty-four patients (group II) had no intracranial pathology and a Glasgow Coma Score (GCS) of less than 13. The morbidity was 2%, and the mortality was 2%. One hundred twenty-three patients (group III) had no intracranial pathology on CT scan and a GCS of 13 or greater. The complication rate in this group was 1%, and there was no neurologically related mortality. Patients who are admitted with a diagnosis of basilar skull fracture and who have a GCS of 13 or greater with no intracranial pathology on CT can be managed without intensive care monitoring.
