Abstract

Superior semicircular canal dehiscence (SSCD) is a condition caused by the absence of bone over one or both of the superior semicircular canals that leads to dysfunction of the vestibular end as result of formation of third window besides round and oval window resulting in altered fluid dynamics. We present a case of 48 year old man presenting with vertigo and aggravation of symptoms with noise. CT temporal bones revealed, bilateral SSCD which was detected in 5 mm interval coronal images. Thus in a middle age group individual presenting with vertigo a diagnosis of dehiscent superior semicircular canal should be considered.
