Fig. 11.4 Coronal CT scan images (0.6 mm) from the same patient as in Fig. 11.2. Note the appearance of dehiscence that is more pronounced on the left side.

Fig. 11.5 Reformatted (0.6 mm) CT scan of the temporal bone, with formatting into the plane of the left superior semicircular canal. Note the obvious dehiscence, which corresponds with the conductive low-frequency hearing loss in the patient in Fig. 11.2.

Magnetic resonance imaging (MRI) is typically normal in SSCD syndrome. MRI may be of diagnostic value if a concomitant CSF leak or meningoencephalocele exists.54 As radiographic technology continues to improve, new protocols and techniques continue to push the diagnostic envelope. Some authors have recently advocated for digital volume tomography (also called cone-beam CT) for its higher resolution and reduced artifact.55,56
