COMMENT: Noncontrast CT imaging of the temporal bones was performed in the axial and coronal planes, utilizing standard protocol, without a prior study for comparison. The IAC's bilaterally are symmetric, with a normal appearance of the cochlea, semicircular canals, ossicles, vestibular aqueducts and course of the seventh cranial nerves bilaterally. The scutum bilaterally are intact. There is minimal mucosal thickening scattered within a few of the mastoid air cells bilaterally. However, the middle ears bilaterally are clear.
