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 basilar skull fracture typically requires a significant degree of trauma to occur. [1] It is defined as a fracture of one or more of the temporal, occipital, sphenoid, frontal or ethmoid bone. [1] Basilar skull fractures are divided into anterior fossa, middle fossa and posterior fossa fractures. [1] Facial fractures often also occur. [1]
visible deformity or depression in the head or face; for example a sunken eye can indicate a maxillar fracture an eye that cannot move or is deviated to one side can indicate that a broken facial bone is pinching a nerve that innervates eye muscles
The Hangman's fracture which is a fracture of the C2 vertebral body or dens of the cervical spine upon which the skull base sits to allow the head to rotate, can also be associated with atlanto-occipital dislocation. Despite its eponym, the fracture is not usually associated with a hanging mechanism of injury. [13]
In time the swelling hardens (calcification) leaving a relatively softer centre so that it appears as a 'depressed fracture'. Cephalohematoma should be distinguished from another scalp bleeding called subgaleal hemorrhage (also called subaponeurotic hemorrhage), which is blood between the scalp and skull bone (above the periosteum) and is more ...
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.
The clivus (/ ˈ k l aɪ v ə s /, [1] Latin for "slope") or Blumenbach clivus is a part of the occipital bone at the base of the skull. [2] It is a shallow depression behind the dorsum sellae of the sphenoid bone. It slopes gradually to the anterior part of the basilar occipital bone at its junction with the sphenoid bone. It extends to the ...
Bone fractures to the crown of the head are linear or depressed and range in severity based on the impact to the skull. The linear fracture involves a break to the skull whereas the depressed fracture results in the scatter of skull fragments. [19] The skull fractures are mainly caused by incidents involving a vehicle, assault, or a fall.
