Temporal Bone Fracture Diagram

Temporal Bone Fracture Diagram. Note the involvement of the external auditory canal laterally and the anteromedial extension to the skull base avoiding the labyrinthine structures. Basilar skull fractures, usually caused by substantial blunt force trauma, involve at least one of the bones that compose the base of the skull.

The tympanic antrum is bounded above by a thin plate of bone, the tegmen tympani, which separates it from the middle fossa of the base of the skull, below by the mastoid process, laterally by the squama just below the temporal line, and medially by the lateral semicircular canal of the internal ear, which projects into its cavity. The temporal bone is a very complicated and important piece of bone located at the base of the skull. As the facial nerve travels through the temporal bone, it can be damaged, with paralysis resulting.

A temporal bone fracture may cause facial paralysis, hearing loss, bruising behind the ear, and bleeding from the ear. Basilar skull fractures most commonly involve the temporal bones but may involve the occipital, sphenoid, ethmoid, and the orbital plate of the frontal bone as well.

The zygomaticotemporal suture separates the zygomatic process of the temporal bone from the temporal process of the zygomatic bone, forming the zygomatic arch. Basilar skull fractures include breaks in the posterior skull base or anterior skull base.

Temporal bone trauma usually is the sequela of blunt head injury.damage to the temporal bone typically requires the application of great force and may cause fracture, hemorrhage, nerve trauma, vascular damage, or disruption of the middle or inner ear structures. The fracture is located on the vault or base of skull and is of linear variety [1].
