They make up about 20% of all skull fractures and are mainly caused by high-velocity blunt trauma and falls from high heights. Depending on their precise location, they can be divided into frontobasal, laterobasal and frontolateral fractures. Possible clinical signs are the presence of cerebrospinal fluid rhinorrhea or otorrhea, periorbital ecchymosis (raccoon eyes), retroauricular ecchymosis (battle sign) and cranial nerve injuries. Furthermore, fractures of the petrous bone can lead to a conductive hearing loss, sensorineural hearing loss as well as dizziness and nausea due to a failure of the labyrinth.PRACTICAL RECOMMENDATIONS: If there are any clinical signs of a basilar skull fracture, neurological deficits or limited consciousness (GCS < 15), a CT should be performed to rule out a basilar skull fracture and accompanying pathologies. In addition, if vascular injury is suspected, a CT angiography should be performed. Treatment is usually interdisciplinary and depends mainly on the accompanying injuries and possible complications. A purely conservative approach with close controls (with imaging) is often sufficient. The surgical approach is primarily used to treat possible complications, for example intracerebral bleeding.PMID:34236447 | DOI:10.1007/s00117-021-00879-3
