Imaging the Temporal Bone
Imaging of the temporal bone must be integrated into the clinical context because the information provided by otologists is of great interest. The temporal bone contains three cavities: two are filled with air (external ear and middle ear) and one contains fluid (inner ear, or labyrinth, connected to the brain by the eighth cranial nerve). The aims of imaging are, in all pathologies, to avoid surprises during surgery of the middle ear and to provide information about the morphology of the cavities, in particular the inner ear and internal auditory meatus. The procedures for analyzing the different structures of the temporal bone on diagnostic images are the same, and regard both the content and the walls of the cavities.
