It consists of three parts: the vestibule, semicircular canals, and cochlea . These are cavities hollowed out of the substance of the bone, and lined by periosteum . They contain a clear fluid, the perilymph, in which the membranous labyrinth is situated . </P> <P> A fracture classification system in which temporal bone fractures detected on CT 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 capsule is the most dense portion of the temporal bone . </P>
