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 basal skull fracture is a fracture in one of the bones at the base of the skull. This is almost always caused by impact trauma such as a hard fall or a car crash. If the temporal bone is affected, one of the following may co-occur: Auricular cerebrospinal fluid discharge; Dizziness; Bruises around the eyes or behind the ears; Facial weakness
A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves. A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen.
When a CSF leak occurs at the temporal bone, surgery becomes necessary in order to prevent infection and repair the leak. [56] Orthostatic hypotension is another complication that occurs due to autonomic dysfunction when blood pressure drops significantly. [ 57 ]
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.
Physical trauma, especially fractures of the temporal bone, may also cause acute facial nerve paralysis. Understandably, the likelihood of facial paralysis after trauma depends on the location of the trauma. Most commonly, facial paralysis follows temporal bone fractures, though the likelihood depends on the type of fracture.
A fracture classification system in which temporal bone fractures detected by computed tomography are delineated based on disruption of the otic capsule has been found to be predictive for complications of temporal bone trauma such as facial nerve injury, sensorineural deafness and cerebrospinal fluid otorrhea. On radiographic images, the otic ...
Enlarged vestibular aqueducts are commonly picked up after newborn hearing screen when a child is identified as having a hearing loss. The hearing loss is commonly mixed and can be of any degree when first identified. The conductive component is due to a third window effect caused by the widened vestibular aqueduct. During an audiologic ...
