From the Guidelines
The management of a suspected basal skull fracture requires prompt stabilization and careful monitoring to prevent complications, with initial management including maintaining airway, breathing, and circulation while immobilizing the cervical spine, as recommended by recent guidelines 1. The patient should be placed on strict bed rest with head elevation at 30 degrees to reduce intracranial pressure. It is essential to avoid nasogastric tube insertion, nasal suctioning, or nasal medications as these could enter the cranial cavity through the fracture. Prophylactic antibiotics, such as ceftriaxone 2g IV daily, are often administered if CSF leakage is present, though this practice remains somewhat controversial 1. Analgesics should be provided for pain control, typically acetaminophen 1000mg every 6 hours, avoiding NSAIDs due to bleeding risk. Neurological observations should be performed regularly to monitor for deterioration. Diagnostic imaging with non-contrast CT scan is essential to confirm the diagnosis and identify complications, as supported by the American College of Radiology 1. Most basal skull fractures heal spontaneously within 7-10 days, but patients require close monitoring for potential complications including meningitis, CSF leaks, cranial nerve injuries, and vascular injuries. Neurosurgical consultation is necessary, though most cases are managed conservatively unless there are complications requiring surgical intervention such as persistent CSF leakage or significant intracranial hemorrhage. Some key points to consider in the management of basal skull fractures include:
- The use of clinical decision tools, such as the Canadian CT Head Rule (CCHR) and the New Orleans Criteria (NOC), to identify patients at high risk of clinically important brain injury 1.
- The importance of considering the patient's age, mechanism of injury, and presence of other risk factors, such as anticoagulant or antiplatelet medications, in the management of basal skull fractures 1.
- The role of MRI in the diagnosis of complications, such as CSF leaks or cranial nerve injuries, particularly in patients with cranial nerve deficits not explained or incompletely characterized by CT 1.
From the Research
Assessment and Management of Basal Skull Fracture
The management of a suspected basal skull fracture involves a comprehensive assessment to identify potential complications and guide treatment. Key considerations include:
- Recognition of the fracture pattern and associated complications, such as cranial nerve or vascular injury, cerebrospinal fluid leak, or meningitis 2
- Diagnosis of cerebrospinal fluid (CSF) leaks, which can be achieved through positive beta-2-transferrin study, thin-slice CT scanning, and MRI cisternography 3
- Imaging evaluation to identify the location and extent of the fracture and associated complications, using techniques such as CT and MRI 4, 5, 6
Diagnostic Approaches
Diagnostic approaches for basal skull fractures and CSF leaks include:
- CT scanning, which can be used to identify the fracture pattern and associated complications 2, 4
- MRI cisternography, which can be used to diagnose CSF leaks and identify the location of the leak 3, 5
- Beta-2-transferrin study, which can be used to confirm the presence of CSF in nasal or aural discharge 3
Treatment Options
Treatment options for basal skull fractures and CSF leaks include:
- Conservative management, which may involve bed rest, hydration, and observation, and may be sufficient for resolving CSF leaks in some cases 3
- Surgical management, which may involve open surgery or endoscopic surgery, and may be necessary for cases with significant complications or persistent CSF leaks 3
- Use of lumbar drains to reduce intracranial pressure and promote healing of CSF leaks 3
