PurposeA head injury (HI) may cause a skull fracture, which may or may not be associated with injury to the brain. In essence, a skull base fracture (SBF) is a linear fracture at the base of the skull. Loss of consciousness and Glasgow coma score (GCS) may vary depending on an associated intracranial pathology. The pathomechanism is believed to be caused by high energy impact directly to the mastoid and supraorbital bone or indirectly from the cranial vault. Aim of this study is to define the correlation between SBF and intracranial hemorrhage (ICH) in patients with HI.MethodsAnalysis of data obtained from a retrospective review of medical records and from a systematized database pertaining to diagnostic criteria of SBF patients based only on clinical symptoms associated with ICH caused by HI treated in the Department of Neurosurgery at Dr. Hasan Sadikin Hospital, Bandung, Indonesia from January 1, 2012 to December 31, 2017. The exclusion criteria included age less than 15 years and no head computed tomography (CT) scan examination provided.ResultsA total of 9006 patients were included into this study in which they were divided into 3 groups: group 1, HI with no ICH; group 2, HI with single ICH and group 3, HI with multiple ICH. In all the SBF cases, SBF at anterior fossa accounted for 69.40% of them, which were mostly accompanied with mild HI (64.70%). Severity of HI and site of SBF correlated with the existence of traumatic brain lesions on CT scan, thus these factors were able to predict whether there were traumatic brain lesions or not. Most of the patients with epidural hemorrhage (EDH) has single traumatic lesion on CT scan, whereas most of the patients with cerebral contusion (CC) has multiple traumatic lesions on CT scan. On patients with both traumatic brain injury and SBF, most of the patients with anterior fossa SBF has EDH; whereas most of the patients with middle fossa SBF were accompanied with CC. Surgery was not required for most of the patients with SBF.ConclusionSBFs were strongly correlated with traumatic ICH lesions patients with anterior fossa SBF were more likely to suffer EDH whereas with middle fossa SBF were more likely to suffer CC.
