Abstract:
Posterior semicircular canal dehiscence represents a third-window lesion manifesting as hearing loss with vestibular dysfunction. Computed tomography findings of a dehiscent posterior canal can be verified with increased vestibular evoked myogenic potential responses as in other third-window lesions. The jugular bulb is the bulbiform connection between the sigmoid sinus and the internal jugular vein at the skull base. High jugular bulb can erode into inner ear structures. According to the literature review, there has been no case report about posterior semicircular canal dehiscence caused by high jugular bulb in Asia. Therefore, the authors report a case with a review of literature.
