| Summary: | Superior semcircular canal dehiscence is a radiological diagnosis which is associated with sound-induced hearing loss, vertigo, nystagmus and oscillopsia. The clinical manifestations have been explained by the absence of a bony cover, generating a ‘third window’. In one temporal bone survey the prevelance was reported as 5 cases in 1000 temporal bones, whereas, bilateral involvement was observed in one case. Here we present an otherwise healthy adult patient suffering from bilateral persistent ear pain, in whom bilateral superior semicircular canal dehiscence was the sole pathology. Bilateral canal dehiscence is a very rare entity and ear pain is unlikely in these cases. To our knowledge, there has been no similar cases reported in the literature so far.
