The Site of Lesion in Hearing Loss : Advances in Otoneuroradiology

The last decade has witnessed significant advances in imaging of the middle and inner ear and the auditory pathways. High resolution computerized tomography (CT) scanners and new magnetic resonance (MR) sequences have been implemented in clinical practice as valuable supportive tools for the Audiologist in the identification of the site of lesion and for the surgical planning by the Otologist. The purpose of this chapter is to review the current advanced methods of neuroradiological evaluation of patients with sensorineural hearing loss (SNHL), either congenital or acquired, especially focusing on the assessment of candidates to cochlear implantation (CI), with plenty of explicative images.
