[Superior semicircular canal dehiscence syndrome: a case of Tullio phenomenon].
Superior semicircular canal dehiscence syndrome is a clinical picture with sound and pressure-induced vertigo, autophony, hearing loss and a lowered bone conduction threshold. It is an important differential diagnosis to otosclerosis and patent eustachian tube. Diagnostic investigations include audiometric testing, nystagmus provocation, computed tomography and vestibular evoked myogenic potentials. Surgical repair of the dehiscence represents a curative therapeutic option. We describe the disease symptoms on the basis of a typical case.
