title: Radiological visualization of the vestibular aqueduct. Technique and morphological features.
abstract: Thin-section tomography in the lateral and off-lateral projections permits radiographic visualization of the vestibular aqueduct, which is seen as an inverted J. The proximal curved portion has a constant configuration, while the distal straight portion varies according to the width of the external aperture and may be tubular, funnel-shaped, or filiform. Nonvisualization of the curved portion does not necessarily mean that it is not present.
