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]
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.
The occipital bone is part of the endocranium, the most basal portion of the skull. In Chondrichthyes and Agnatha, the occipital does not form as a separate element, but remains part of the chondrocranium throughout life. In most higher vertebrates, the foramen magnum is surrounded by a ring of four bones.
It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from the nose is cerebrospinal fluid. Treatment may be conservative (as many cases resolve spontaneously), but usually involves ...
The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra.. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the ...
Battle's sign, also known as mastoid ecchymosis, is an indication of fracture of middle cranial fossa of the skull. These fractures may be associated with underlying brain trauma . Battle's sign consists of bruising over the mastoid process as a result of extravasation of blood along the path of the posterior auricular artery . [ 1 ]
While some people dread gift shopping, I thrive when it comes time to shop for the different people on my list. I love Christmas gift shopping, whether I’m trying to find a gift for my mother-in ...
The Jefferson fracture can be associated with this injury, with the C1 ring, or atlas, being fractured in several places, allowing the spine to shift forward relative to the skull base. 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 ...
