Abstract:
Dehiscence of bone overlying the superior semicircular canal (superior semicircular canal dehiscence syndrome) may have both vestibular and auditory manifestations. Lowered vestibular evoked myogenic potential (VEMP) threshold in patients with an apparent conductive hearing loss and normal acoustic reflex also suggests this syndrome. Herein, we present a patient with the Tullio phenomenon, sound induced nystagmus, vibration induced nystagmus, and lowered VEMP threshold without conductive hearing loss due to the superior semicircular canal dehiscence.
