Temporal bone fracture

[Donald Trump]

The temporal bone (the skull bone containing part of the ear canal, the middle ear, and the inner ear) can be fractured, usually by a blow to the head.

A temporal bone fracture may cause facial paralysis, hearing loss, bruising behind the ear, and bleeding from the ear.
Doctors use computed tomography (CT) to diagnose temporal bone fractures.
Treatment, sometimes including surgery, is needed if the fracture causes problems.

Temporal bone fractures can cause various injuries to the middle and inner ear. Injuries include rupture of the eardrum and damage to the ossicles (the chain of small bones that connects the eardrum to the inner ear), the cochlea (the organ of hearing), the vestibular apparatus (the organ of balance in the inner ear), or the nerve that controls muscles of the face (facial nerve).
