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.
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. [5] The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment. [6]
Basilar skull fracture. A basilar skull fracture is a break of a bone in the base of the skull. [1] Symptoms may include bruising behind the ears, bruising around the eyes, or blood behind the ear drum. [1] A cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in fluid leaking from the nose or ear. [1]
Clivus (anatomy) The clivus (/ ˈklaɪvəs /, [ 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.
The anterior cranial fossa is a depression in the floor of the cranial base which houses the projecting frontal lobes of the brain. It is formed by the orbital plates of the frontal, the cribriform plate of the ethmoid, and the small wings and front part of the body of the sphenoid; it is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of ...
A cephalohematoma (American English), also spelled cephalohaematoma (British English), is a hemorrhage of blood between the skull and the periosteum at any age, including a newborn baby secondary to rupture of blood vessels crossing the periosteum. Because the swelling is subperiosteal, its boundaries are limited by the individual bones, in ...
Diagnosis. 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. The dura that is now visible is carefully examined to ...
The middle cranial fossa is formed by the sphenoid bones, and the temporal bones. It lodges the temporal lobes, and the pituitary gland. [ 1 ][ 2 ] It is deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior cranial fossa by the clivus and the petrous crest.
