To identify bony labyrinth defects as causing symptoms that might otherwise be difficult to understand.
Imaging investigation on cases of lowered vestibular evoked myogenic potentials (VEMP) threshold.
Academic tertiary case-referral medical center.
One patient with continuous bilateral tinnitus.
High-resolution computed tomography of petrous bone was performed after audiometry, impedance, and VEMP recording.
We found a previously unreported dehiscence of the bony plate between the basal turn of the cochlea and the carotid canal.
A VEMP study could prompt diagnostic imaging tests that might otherwise be neglected. Moreover, it is important to consider the possibility of a bony dehiscence involving not just the semicircular canals.
