In case of head injury, a dural tear is likely in case of a depressed skull fracture. A burr hole is made through the normal skull near the fractured portion, and Adson's elevator is introduced. Underlying dura is separated carefully from the overlying depressed bone fragments.
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
A key part of the protocols is the "Cogsport" test (also known as COG), a computer-based test of cognitive function. Each player undergoes the test before the start of a new season, and is then tested again on it after a head injury, and the results compared, to determine possible impairment.
Closed-head injury is a type of traumatic brain injury in which the skull and dura mater remain intact. Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people.
More common in adults than in children, intraparenchymal bleeds are usually due to penetrating head trauma, but can also be due to depressed skull fractures. Acceleration-deceleration trauma, [24] [25] [26] rupture of an aneurysm or arteriovenous malformation (AVM), and bleeding within a tumor are additional causes.
The skull can be fractured, but not necessarily. A penetrating head injury occurs when an object pierces the skull and breaches the dura mater. Brain injuries may be diffuse, occurring over a wide area, or focal, located in a small, specific area. A head injury may cause skull fracture, which may or may not be associated with injury to the ...
The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [2] [3] The fracture line extends through the zygomatic arch, the pterygoid plates, the lateral and medial orbital walls, the nasal bones, and the nasal septum.
Pneumocephalus and comminuted fracture of the frontal sinus Pneumocephalus is the presence of air or gas within the cranial cavity . It is usually associated with disruption of the skull : after head and facial trauma , tumors of the skull base, after neurosurgery or otorhinolaryngology , and rarely, spontaneously.
