title: Imaging in sensorineural deafness.
abstract: In this paper, the authors describe, in details, the techniques and the indication of CT scanner and MRI for the evaluation of neurosensory deafness. CT scanner allows to study bony and pneumatized structures of the ear. CT scanner is mostly indicated for the study of congenital deafness, post-trauma deafness and unilateral progressive deafness for which the otoscopy is normal. MRI allows the study of fluid compartments, nerves, vascularization and tissue. MRI will be chosen to evaluate sudden sensory neural deafness and unilateral deafness. However, it is worth to mention that CT scanner and MRI are complementary and that precision of the imaging system as well as a strong collaboration between the otolaryngologist and the radiologist are mandatory.
