Frequency of Extradural Hematoma in Patients with Skull Fracture after Head Injury
Objective: To assess the frequency of patients with extradural hematoma who have a skull fracture on x-ray skull presenting with a head injury.
Material & Methods: A descriptive case series was conducted at the Department of Neurosurgery, RMU & Allied Hospital, Rawalpindi. 322 patients fulfilling the selection criteria were enrolled in the study from Emergency Ward. Patients with head injury having skull fracture undergone a CT scan for assessment of presence or absence of extradural hematoma. CT scan was done by a single senior radiologist for all patients.
Results: Mean age of patients in this study was 41.31 ± 14.67 years. Among the patients 259 (80.4%) were male and 63 (19.6%) were females. The mean duration of injury of the patients was 6.37 ± 3.40. Extradural hematoma was diagnosed in 104 (32.3%) patients. Age and site of fracture showed a statistically significant association for extradural hematoma. Whereas gender, duration of injury, and type of fracture did not show significant association for extradural hematoma.
Conclusion: Results of this study showed a low frequency of extradural hematoma in patients who presented with a head injury. Still, any patient suspected of head injury leading to skull fractures must be examined on CT scan to avoid and timely detect the intracranial bleeding in order to avert the complications and mortality after traumatic head injury.
