Abstract: The ear is an organ of special sense which is crucial for hearing, balance and orientation. It has an extremely complicated anatomy with minute structural components. It is divided into three sections, the outer, middle, and inner ear. The outer ear consists of the auricle, the external auditory canal and terminates at the tympanic membrane. The middle and inner ear are housed in the petrous part of temporal bone. Congenital sensorineural hearing loss arises as a result of abnormalities in the inner ear, the vestibulocochlear nerve, or the processing centers of the brain. Imaging plays an important role in the evaluation of congenital sensorineural hearing loss.
