COMPARISON: CT Brain dated [**Date**] FINDINGS: The external auditory canals are stenotic bilaterally, worse on the left, with thickened tympanic membranes noted bilaterally, likely representing congenital cholesteatomas. The middle ear cavities are small bilaterally. The inner ear structures, including the lateral semicircular canals, vestibule, and cochlea are dysplastic bilaterally. The incus and malleus are intact bilaterally. Inflammatory debris is seen in the region of the oval window on the right, less so on the left.
