Pathology of the oval and round window may result in conductive and mixed hearing loss. Familiarity with the normal anatomy, appropriate technical procedures and imaging findings related to oval and round window pathology can optimize pre-clinical assessment and management of conductive and mixed hearing loss.  

Imaging of the oval and round windows is important in the assessment of hearing loss, vertigo and tinnitus particularly in the context of congenital and acquired malformations, trauma, otosclerosis and chronic otitis media. We review the normal anatomy of the oval and round windows and the appropriate CT and MRI techniques for imaging them. MDCT and MRI features of the following oval and round window pathologies will be reviewed: 1. Trauma with and without fractures of the oval and round windows. 2. Otosclerosis of the oval and round windows. 3. Malformations (congenital and acquired) of the oval and round windows. 4. Post surgical complications related to the oval window such as dislocation of prosthesis into the vestibule through the oval window.
