title: [Imaging of the inner ear].
abstract: New computed tomography (CT) and magnetic resonance (MR) techniques allow more detailed anatomic studies of the inner ear. CT is still the best technique to study patients with fractures, congenital malformations and otodystrophies involving the inner ear. During recent years MR imaging has emerged as an excellent method to detect pathology in the internal auditory canal, membranous labyrinth and bony labyrinth and to characterize petrous apex lesions. MR has even proved its value in patients with fractures and congenital malformations making the diagnosis of, for instance, labyrinthine concussion and absence of the vestibulocochlear nerve possible. The diagnosis of acute/chronic labyrinthitis and intralabyrinthine tumors has also became possible. However, MR and CT are often complementary, as is the case in patients with mixed hearing loss, congenital malformations and petrous apex lesions.
