).The head, deservedly, has been coined the central hub of individuality and communication with the outside world. By virtue of the critical structures encompassed by the craniofacial skeleton, head trauma can have devastating and debilitating consequences. With advancement of our understanding of brain trauma, technology, and medicine, more victims survive to face the sequelae of what were once terminal injuries. There are 30 million trauma-related hospital visits annually, and approximately 16% are associated with traumatic brain injuries (TBIs). Children, older adolescents, and adults aged 65 years or older are among those most likely to sustain TBIs. The incidence of TBIs is also higher in males. As per the Centers for Disease Control and Prevention (CDC) report, males aged 0 to 4 years have the highest rates of TBI-related emergency department visits. However, the rate of hospitalization and death is higher amongst patients 65 years of age and older. Mechanism of injury leading to TBI varies among the demographic parameters. For example, assault and motorized vehicle crashes are major causes of TBI-related deaths up to the third decade of life, whereas falls are implicated in most of the TBI-related deaths in individuals 65 years of age and older population. In 2010, $76.5 billion was the estimated economic burden of TBI. 1 In light of the societal and financial burdens involved in cranial trauma and as a result of critical anatomic relationships between important neurologic structures, such as the brain and skull, skull base injuries are an important part of the head trauma mélange. Skull base fractures have been reported in 12% of all head injuries and 20% of all skull fractures. 2 With the skull base being located at the anatomic gateway of neurovascular connections of the brain with the periphery, timely diagnosis and management of skull base fractures and their complications are of paramount importance. This work aims to briefly review demographics, diagnosis, complications, and surgical management of skull base injuries.
Mechanism of Injury
AbstractTraumatic injuries to the skull base can involve critical neurovascular structures and present with symptoms and signs that must be recognized by physicians tasked with management of trauma patients. This article provides a review of skull base anatomy and outlines demographic features in skull base trauma. The manifestations of various skull base injuries, including CSF leaks, facial paralysis, anosmia, and cranial nerve injury, are discussed, as are appropriate diagnostic and radiographic testing in patients with such injuries. While conservative management is sometimes appropriate in skull base trauma, surgical access to the skull base for reconstruction of traumatic injuries may be required. A variety of specific surgical approaches to the anterior cranial fossa are discussed, including the classic anterior craniofacial approach as well as less invasive and newer endoscope-assisted approaches to the traumatized skull base.
