On the left, no vestibular aqueduct aperture is visible at all. On the right, there is a little irregularity of the medial aspect of the temporal bone which may represent a severely narrowed aqueduct opening.
The inner ears appear normal bilaterally.
This is a "definite" case of according to the American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium1 criteria. In addition, CT findings of severely narrowed or absent vestibular aqueduct openings on both sides are supportive.
See Yamane et al.2 for images and useful illustrations.
In contradistinction of these CT features, vestibular aqueducts can be enlarged (normally congenital) as a cause of hearing loss.
